Abstract:
In recent years biofuels have obtained a considerable interest, due to the implementation of ruling and gradual replacement of fossil fuels. One of production steps at gaining the oil is a pressing process. Wastes come into being from this process. These wastes are used as feed, fertilizer prospectively as fuel. A contemporary scientific literature pays attention namely to one of prospective produces which is a produce of the tropical and subtropical zones Jatropa curcas. Tests were performed at Jatropha Curcas seeds of a brown colour (that means gnaw). The aim of a research is an analysis of Jatropa curcas seed from the utilization point of view of the gross calorific value. The basic instrument to evaluate the gross calorific value of each variant of the experiment was a calorimeter PARR 6200 and digital scales for accurate laboratory weighing.

Abstract:
La baisse de la fertilité des sols due à la mauvaise gestion des terres et l’utilisation excessive des engrais chimiques a motivé le regain d’intérêt dans la recherche de fertilisants organiques respectant l’environnement pour un développement durable. Pour évaluer l’efficacité agronomique des litières de Jatropha sur la production de la tomate, une étude a été conduite en champs dans des pots de 20 cm de diamètre. Le dispositif expérimental est un bloc de Fischer randomisé avec un total de 64 pots (4 traitements x 4 répétitions x 4 unités expérimentales). Les résultats ont montré que les litières de Jatropha curcas et Jatropha gossypifolia ont amélioré la croissance et le développement (le diamètre et la ramification de la tige, le nombre de feuille et de fruits ainsi que la masse des fruits) de la tomate par rapport au témoin. La litière de Jatropha curcas a induit une large amélioration de la masse des fruits (33,09 g) par rapport aux autres traitements : le témoin (19,99 g), la litière de Jatropha gossypifolia (20,44 g) et l’engrais chimique (24,02 g). Pour une culture dont on aimerait avoir des gros fruits l’utilisation des fertilisants organiques à base des litières de Jatropha curcas pourrait être conseillée.Mots clés : Fertilisant organique, Litière, Jatropha curcas, Jatropha gossypifolia, Nord-Cameroun. English Title: Effect of organic fertilization based on leaf litter of Jatropha curcas L. and Jatropha gossypifolia L. on the tomato crop (Lycopersicon esculentum Mill.) in Guider (North Cameroon)The decline in soil fertility due to poor land management and excessive use of chemical fertilizers has induced new interest in the quest for environmentally friendly organic fertilizers for sustainable development. To assess the agronomic effectiveness of Jatropha litter on tomato production, a study was conducted in the field in pots of 20 cm in diameter. The experimental set-up is a randomized Fischer block with a total of 64 pots (4 treatments x 4 repetitions x 4 experimental units). The results showed that the litters of Jatropha curcas and Jatropha gossypifolia improved the growth and development (the diameter and branching of the stem, the number of leaves and fruits as well as the mass of the fruits) of the tomato compared to the witness. Jatropha curcas litter induced a large improvement in fruit mass (33.09 g) compared to other treatments: the control (19.99 g), Jatropha gossypifolia litter (20.44 g) and chemical fertilizer (24.02 g). For a crop from which we would like to have larger fruits, the use of organic fertilizers based on Jatropha curcas litter could be recommended.Keywords: Organic fertilizer, Litter, Jatropha curcas, Jatropha gossypifolia, North Cameroon.

Abstract:
<p style="text-align: justify;">Jatropha curcas twigs are part of the Jatropha curcas which can be utilized as herbal treatment by the community to overcome the vaginal discharge problem. Vaginal discharge is a common symptom experienced by most women caused by Candida albicans infection. This research used the true experiment with posttest only control design which aimed to know the content of phytochemistry and antifungal potential of Jatropha curcas twigs extract on Candida albicans growth. Extract of Jatropha curcas in this study was obtained through a solvent extraction process using ethanol 96% by the method of maceration. The method used for the phytochemistry test was a qualitative method, while for the antifungal potential test was done by diffusion method with the concentration of 10%, 25%, 30%, 40% and 50%. The results of Phytochemistry test showed that Jatropha curcas twigs extracts are saponins, tannins, and flavonoids, but no alkaloid compounds were found, however a test result of the antifungal potential test showed that the average diameter of inhibition zone of Candida albicans growth is 0 mm. The conclusion of this study is Jatropha curcas twigs extracts can not inhibit Candida albicans growth, For other researchers which use jatropha curcas twigs, are suggested to do a phytochemical test quantitatively and to test the antifungal potential with dilution method.

O pinhÃo manso (Jatropha curcas L.) à considerado uma fonte potencial para a produÃÃo de biocombustÃveis, tendo por base a alta produtividade e qualidade do Ãleo extraÃdo de suas sementes. Entretanto, seu uso à inviabilizado para alimentaÃÃo humana e animal devido à presenÃa de fatores antinuticionais como a curcina e, em especial, os Ãsteres de forbol. A utilizaÃÃo de ferramentas biotecnolÃgicas, como a cultura de tecidos, pode vir a minimizar ou solucionar essas limitaÃÃes. Nesse contexto, o objetivo desse trabalho foi propagar in vitro plantas inteiras via cultivo de Ãpices caulinares obtidos a partir de sementes de pinhÃo manso germinadas in vivo e in vitro; determinar a reprodutibilidade de um protocolo de regeneraÃÃo disponÃvel na literatura e definir, atravÃs de estudos histolÃgicos, a origem da planta regenerada in vitro. Para a propagaÃÃo in vitro utilizou-se Ãpices caulinares, como explantes, que foram colocados em meio MS suplementado com as citocininas BAP (6-benzilaminoprina), KIN (cinetina) e 2-iP (2-isopenteniladenina) na concentraÃÃo de 2,0 mg.L-1. O BAP apresentou os melhores resultados no desenvolvimento dos Ãpices caulinares. Este e a giberelina foram utilizados juntos no mesmo meio ou separados, para a induÃÃo do alongamento dos mesmos. O Ãcido indol-3-butirÃco (AIB) foi usado para o enraizamento. A suplementaÃÃo do meio de cultura com BAP foi eficiente no desenvolvimento dos Ãpices caulinares e o alongamento apresentou Ãxito com o uso do GA3 individualmente. O enraizamento com o AIB foi conseguido. A fim de determinar a reprodutibilidade do protocolo de organogÃnese, cotilÃdones de sementes de pinhÃo manso germinadas in vitro foram colocados em meio MS suplementado com BAP e AIB para a induÃÃo da formaÃÃo de partes aÃreas, estas foram alongadas com BAP e enraizadas com AIB. AlÃm disso, os explantes cotiledonares foram colocados com a face abaxial e adaxial em contato com o meio de cultivo a fim de estabelecer a melhor posiÃÃo do mesmo na regeneraÃÃo in vitro. Plantas inteiras de J. curcas L. foram obtidas a partir da utilizaÃÃo do protocolo testado. A melhor posiÃÃo do segmento cotiledonar foi a face adaxial em contato com o meio, onde 56% dos explantes formaram partes aÃreas. A anÃlise histolÃgica foi feita com a coleta de explantes cotiledonares em intervalos sequenciais de 0, 5, 10, 15 e 25 dias de permanÃncia do meio de regeneraÃÃo. O estudo anatÃmico possibilitou o acompanhamento da organogÃnese do pinhÃo manso, no qual cÃlulas parenquimÃticas prÃximas à regiÃo adaxial do explante cotiledonar se dividiram e formaram as partes aÃreas. Os dados obtidos nesse trabalho mostraram que ambos os protocolos utilizados, a partir de Ãpices caulinares e de explantes cotiledonares, foram eficientes no processo de regeneraÃÃo; as anÃlises histolÃgicas sugerem que a regeneraÃÃo ocorre via organogÃnese direta e possivelmente apresenta origem multicelular.
The physic nut (Jatropha curcas L.) is considered a potential source for the biofuel production, because of its high productivity and oil quality extracted from the seeds. However, its use is unfeasible for human and animal food due to antinutritional factors like the curcin protein and specially the secondary metabolites â phorbol esters. The application of biotechnological tools, like tissue culture, can be used to overcome these limitations. In this context, the aim of this work was to propagate whole plants in vitro using shoot cultures obtained from physic nut seeds germinated in vitro and in vivo; to determine the reproducibility of a regeneration protocol available in the literature, and to define through histological studies, the origin of the regenerated plant in vitro. For the in vitro propagation, shoots were used as explants sources, which were placed on MS medium supplemented with the cytokinins BAP (6- benzylaminopurine), KIN (kinetin) e 2-iP (2- isopentenyl adenine), 2,0 mg.L-1. BAP showed the best results in the development of the shoots. This regulator was used alone or in association with gyberelins for the elongation of the shoots. The indole-3-butyric-acid was used for the rooting. The supplementation of the medium culture with BAP was efficient in the development of the shoots and the elongation was superior with the use of GA3 alone. The rooting was achieved with AIB. To determine the reproducibility of an organogenesis protocol, cotyledons from physic nut seeds germinated in vitro were placed on MS medium supplemented with BAP and AIB for the promotion of aerial which were elongated with BAP and rooting with AIB. The cotyledonary explants were placed with the abaxial and adaxial face in contact with the medium to establish the best position of it in the in vitro regeneration. Whole plants of J. curcas L. were obtained using the protocol tested. The best position of the cotyledonar segment was the adaxial face in contact with the medium, where 56% of the explants formed shoots. The histological analysis was made with cotyledonary explants collected in sequential intervals of 0, 5, 10, 15 e 25 days of permanency in the regeneration medium. The anatomical study allowed the accompaniment of the organogenesis in physic nut, where parenchymal cells next to the adaxial region of the cotyledonar explants were divided and formed the shoots. The data obtained from this work showed that both protocols used, from shoots tips and cotyledonar explants, were efficient in the regeneration process; the histological analysis suggests that regeneration occurs via direct organogenesis and possibly presents multicellular origin.

Abstract:
Se analiza la variabilidad morfológica de Jatropha curcas en 20 poblaciones cultivadas en las regiones de Lambayeque, Piura, Tumbes, San Martín y Ucayali. Se muestrearon 123 individuos de 2-4 cm de dap; se registraron ocho parámetros morfométricos como: altura total de la planta, número de ramas de la planta, número de lóbulos del limbo, longitud del limbo, del pecíolo, del fruto, largo y ancho de la semilla. Los parámetros fueron analizados mediante la prueba de comparaciones de medias ANOVA (p menor 0.05); a los que mostraron diferencias significativas se realiza el análisis de componentes principales. Existen diferencias significativas de seis parámetros entre las poblaciones; respecto a la altura total de la planta, el mayor valor se registra para la población de La Libertad, y el menor valor para la población de San Isidro; respecto a la cantidad de ramas, el mayor valor se registra para Olmos, y el menor valor para Chazuta; respecto a la longitud del limbo y el pecíolo, el mayor valor se registra para Tambo Grande, y el menor valor para Olmos; respecto a la cantidad de lóbulos, el mayor valor se registra para Tambo Grande, y el menor valor para Curimaná; respecto a la longitud del fruto, el mayor valor se registra para la población de Oidor y el menor valor en la población Yarinacocha. Los resultados del Análisis de Componentes Principales mostraron que el 66.9% de la varianza correspondió a los 2 primeros componentes. No se observaron grupos claramente definidos; sin embargo, las poblaciones de la región costera formaron grupos distintos con respecto a las poblaciones de la región amazónica.

Abstract:
CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior
Jatropha curcas L. is a plant native to America and belongs to the Euphorbiaceae family. Currently it is gaining economical interest mainly because it is an oilseed crop with potential to produce biodiesel. However, presence of phorbol esters (a class of diterpenes) that are the major toxic constituents of the seeds, limits a better usage of the plant, by making the use of the residue, obtained after the oil extraction from the seeds, unfeasible for animal feed, due to its pro-carcinogenic activity and inflammatory action. Proteomic analysis of the plastids isolated from developing seeds of Jatropha is important because the synthesis of fatty acid as well as phorbol esters, the two most attractive compounds in the study of Jatropha curcas, occur in plastids. Proteomic analysis of this organelle is crucial to better understand and explore not only the biosynthetic pathway of these two compounds but other metabolic pathways , and addtionaly providing foundation for researchs that aimed to develope genotypes with more suitable characteristics for industrial applications. In this study, we performed a proteomic analysis of plastids isolated from the endosperm of developing Jatropha curcas seeds that were in the initial stage of deposition of protein and lipid reserves. Proteins extracted from the plastids were digested with trypsin, and the peptides were applied to an EASY-nano LC system coupled online to an ESI-LTQ-Orbitrap Velos mass spectrometer, and this led to the identification of 1103 proteins representing 804 protein groups, of which 923 were considered as true identifications, and this considerably expands the repertoire of J. curcas proteins identified so far. Of the identified proteins, only five are encoded in the plastid genome, and none of them are involved in photosynthesis, evidentiating the nonphotosynthetic nature of the isolated plastids. Homologues for 824 out of 923 identified proteins were present in three different plastids proteins databases i.e. PPDB, SUBA and PlProt, while homologues for 13 proteins were not found in any of these three databases but were marked as plastidial by at least one of the three prediction programs used (TargetP, ChloroP and PlantMPloc). Functional classification showed that proteins belonging to amino acids metabolism comprise the main functional class, followed by carbohydrate, energy, and lipid metabolisms. The small and large subunits of Rubisco were identified, and their presence in plastids is considered to be an adaptive feature counterbalancing for the loss of one-third of the carbon as CO2 as a result of the conversion of carbohydrate to oil through glycolysis. While several enzymes involved in the biosynthesis of several precursors of diterpenoids were identified, we were unable to identify any terpene synthase/cyclase, which suggests that the plastids isolated from the endosperm of developing seeds do not synthesize phorbol esters. In conclusion, this study provides insights into the major biosynthetic pathways and certain unique features of the plastids from the endosperm of developing seeds at the whole proteome level.
O pinhÃo manso (Jatropha curcas L.) à uma planta nativa da AmÃrica, pertencente à famÃlia Euphorbiaceae. Atualmente, ela desperta interesse econÃmico principalmente por se tratar de uma oleaginosa com potencial para a produÃÃo de biodiesel. Entretanto, a presenÃa de Ãsteres de forbol (uma classe de diterpeno), que sÃo os principais constituintes tÃxicos das sementes, limita uma melhor utilizaÃÃo dessa planta, por inviabilizar o uso do resÃduo de extraÃÃo do Ãleo das sementes na alimentaÃÃo animal, bem como, por apresentar atividade prÃ-carcinogÃnica e aÃÃo inflamatÃria. A anÃlise proteÃmica de plastÃdeos, isolados de sementes em desenvolvimento de pinhÃo manso, à uma importante vertente de estudo, pois tanto a sÃntese de Ãcidos graxos como dos Ãsteres de forbol, os dois compostos mais atrativos no estudo de Jatropha curcas, ocorrem nos plastÃdeos. O estudo proteÃmico dessa organela torna-se crucial para melhor compreender e explorar nÃo somente as vias biossintÃticas desses dois compostos, como de outras vias metabÃlicas, alÃm de proporcionar um conjunto de dados que pode ser utilizado em pesquisas voltadas para o desenvolvimento de genÃtipos com caracterÃsticas mais adequadas para aplicaÃÃes industriais. No presente trabalho, realizou-se uma anÃlise proteÃmica de plastÃdeos isolados do endosperma de sementes em desenvolvimento do pinhÃo manso, que estavam nos estÃgios iniciais de deposiÃÃo de lipÃdios e proteÃnas de reserva (25-30DAA), confirmados por meio de anÃlises histolÃgica e histoquÃmica. As proteÃnas extraÃdas dos plastÃdeos foram digeridas com tripsina e os peptÃdeos foram aplicados no sistema de nano-LC EASYII acoplado online ao espectrÃmetro de massa nano ESI LTQ-Orbitrap velos, o que resultou na identificaÃÃo 1103 proteÃnas, representando 804 grupos de proteÃnas, dos quais 923 foram consideradas identificaÃÃes verdadeiras. Isso expandiu consideravelmente o repertÃrio de proteÃnas do pinhÃo manso atà agora identificas. Dentre as proteÃnas identificadas, apenas 5 sÃo codificadas pelo genoma plastidial, e nenhuma delas està envolvida na fotossÃntese, o que evidencia a natureza nÃo fotossintÃtica dos plastÃdeos isolados. HomÃlogos de 824, dentre as 923 proteÃnas identificadas, estavam presentes nos bancos de dados PPDB, SUBA e PlProt, enquanto homÃlogos para 13 proteÃnas nÃo foram encontrados em nenhum dos trÃs bancos de dados plastidiais, mas foram detectados como plastidiais por pelo menos um dos trÃs programas de prediÃÃo de localizaÃÃo subcelular utilizados (TargetP, ChloroP, PlantMPloc). A classificaÃÃo funcional mostrou que a maioria das proteÃnas identificadas pertencia ao metabolismo dos aminoÃcidos, seguido dos metabolismos dos carboidratos, energÃtico e dos lipÃdios. As subunidades maiores e menores da Rubisco foram identificadas, e sua presenÃa nos plastÃdeos foi considerada uma caracterÃstica adaptativa para contrabalancear a perda de um terÃo do carbono na forma de CO2 como um resultado da conversÃo de carboidratos em Ãleo atravÃs da glicÃlise. Apesar de enzimas envolvidas na biossÃntese de diversos precursores dos diterpenÃides terem sido identificadas, nÃo foi detectado nenhuma terpeno sintase/ciclase, o que sugere que os plastÃdeos isolados do endosperma de sementes em desenvolvimento nÃo sintetizam Ãsteres de forbol, apesar de uma grande quantidade desse composto ser encontrada neste tecido. Como conclusÃo, o presente trabalho proporciona insights sobre as principais vias biossÃntÃticas, e sobre caracterÃsticas peculiares dos plastideos isolados do endosperma de sementes em desenvolvimento.

Abstract:
Biodiesel is primarily produced by transesterification of edible oils. Increasing concern about using food supplies for fuel has generated interest in alternative raw materials. Furthermore, there are numerous steps between harvesting of oilseeds and final production of biodiesel that can be integrated, thereby simplifying the process and making it more suitable for distributed production. Hence, in this study, the production of biodiesel via in situ transesterification of non-edible Jatropha curcas seed has been investigated. The main aim was to investigate the parameters of the process, with a view to reducing the substantial excess of methanol required. A significant secondary aim was to investigate the possibility of utilising other compounds that come out from the process. “Design of experiments” was employed to study the parameters at lab-scale, with the matrix boundary being determined beforehand using one-at-a-time experiments. The reduction of methanol excess was attempted by use of two co-solvents, hexane and diethylmethane (DEM), and by replacing methanol with methyl acetate. It was found that in situ transesterification run using particle sizes below 0.71 mm, a 400:1 molar ratio of methanol to oil, 60 minutes, and a minimum of 300 rpm mixing intensity yielded the highest biodiesel yield of 83 wt %. NaOH concentration and reaction temperature were not found to be significant variables, and were set at 1.0 N and 30oC respectively. DEM was a more effective co-solvent than hexane. The addition of DEM to the process at 400:1 molar ratio experiment increased the yield from 83 to 92 wt %. When methyl acetate was used to replace methanol, the requirement of molar ratio of solvent:oil reduced significantly to 175:1 to achieved 86.8 wt% of biodiesel. The solid meal was shown to contain substantial amounts of protein, making it a valuable co-product stream. Previously J. curcas meal had had little value as animal feed due to its toxicity, but this may be reduced or removed by this process.

Abstract:
Interest and investment in biofuel production is growing in response to political and economic drivers associated with concerns over fossil fuel depletion; the need for energy security; greenhouse gas emission reduction demands; and the perceived potential for biofuel production to contribute to rural development and poverty alleviation. Despite this, empirical data on the impacts of biofuel crops are limited and their potential role in enabling livelihood diversification activities in sub-Saharan Africa is under-explored. Addressing this gap, this research takes an integrated case study approach to assess the impacts of different Jatropha curcas cultivation models on rural livelihoods across a range of study sites in Malawi. The research develops and adopts an integrated research methodology that combines the Sustainable Livelihoods Framework (SLF) with the diffusion of innovation model, using participatory and conventional social science research methods to achieve a multi-scale analysis spanning from local to national levels. Findings show that the overall approach to cultivation (from planting method, through production and processing to marketing) is more important in providing a livelihood contribution than the model of cultivation used. When Jatropha is promoted as a boundary fence, the crop and its by-products (such as seedcake fertiliser) can contribute to all 5 livelihood asset groups (natural, physical, financial, human and social capitals): directly or indirectly through financial capital substitution. However, a complex set of factors are involved in farmers' adoption decisions, .which intimately link the livelihood context, communication channels and the characteristics of the innovation itself. This results in varying numbers of households cultivating the crop in the case study villages. In addition, constraints identified at the local to national level mean livelihood benefits are yet to be fully realised. Communication amongst the diverse range of stakeholders involved in Jatropha cultivation in Malawi is characterised by isolated networks, individuals and groups at the local to sub- national level. At the national level, the private sector dominates policy dialogue. Moreover, relevant legislation and policy is absent, hindering the development of the sector. Policy recommendations and action points for actors are presented in order to address these constraints. At the national level, it is recommended that the government of Malawi should prioritise rural development as a policy goal for the future of national biofuel production and take steps to develop a coherent biofuels policy which is fully integrated into national development policies. At local to sub-national levels, stakeholder communications must be improved in order to facilitate knowledge management and governance of the sector, and investments must be made in the extension services network.

In this work was determined, for the first time, the volatile composition from fresh and dried leaves of six accessions (named PM-2, PM-7, PM-10, PM-11, PM-12 e PM-14) and a cultivar (EPAMIG, named here EMB) of Jatropha curcas L. The volatile compounds was extracted by hydrodistillation and then analyzed by GCMS. Thus, it was possible to observe that the (Z)-3-hexen-1-ol was the major compound in the fresh leaves (>70% in all accessions). Alcohols also predominated in the dried leaves, mainly (Z)-2-penten-1-ol and (Z)-3-hexen-1-ol, but others constituents were identified in significant proportions included benzenoid compounds such as benzaldehyde. The influence of drying on volatile composition from leaves of J. curcas was evaluated on the PM-2 accession. Besides, this work also describes the development of a High Performance Liquid Chromatograpy (HPLC) method for differentiation of six accessions and a cultivar (EPAMIG) from fresh and dried leaves of J. curcas. The methanol extracts of the leaves were analyzed by HPLC-DAD and after stages of optimizations, we obtained the fingerprint chromatograms. For a comparative analysis of the accessions and a cultivar, were applied chemometric tools of Principal Component Analysis (PCA) and Hierarchical Cluster Analysis (HCA), which it was possible to discriminate the samples from dried leaves according to their origins. The methanol extracts of the leaves were submitted to cytotoxicity assay against four tumor cell lines (HCT-8, HL-60, SF-295 and MDA-MB435), presenting IC50 values of 25.13 μg/ml, against HL-60 cell line for EMB sample considered promising by National Institute of Cancer, USA (NCI). The biological activity of this extracts was evaluated on the development of Spodoptera frugiperda, considered as a primary pest in corn crop. It was observed 60% larval mortality.
No presente trabalho foi determinado, pela primeira vez, os compostos voláteis das folhas frescas e secas de Jatropha curcas L. pela técnica de hidrodestilação, para seis diferentes acessos (denominados de PM-2, PM-7, PM-10, PM-11, PM- 12 e PM-14) e uma cultivar (EPAMIG, denominada de EMB). As análises foram realizadas através de CG/EM, obtendo-se o (Z)-3-hexen-1-ol (75,7±18,2%) como composto majoritário nas folhas frescas, com percentuais superiores a 70% entre os acessos. Nas folhas secas obteve-se como compostos majoritários o (Z)-2- penten-1-ol (14,9±11,3%), (Z)-3-hexen-1-ol (9,6±9,1%) e o benzaldeído (3,9±2,7%). Um experimento de secagem foi realizado para o acesso PM-2 com intuito de verificar o efeito da secagem na composição dos voláteis das folhas de J. curcas. Neste trabalho também foi desenvolvido um método por Cromatografia Líquida de Alta Eficiência (CLAE) para diferenciação dos seis acessos e da cultivar (EPAMIG) para folhas frescas e secas de J. curcas. Os extratos metanólicos das folhas foram analisados por CLAE-DAD e após etapas de otimizações, foram obtidos os cromatogramas fingerprints. Para uma análise comparativa entre os acessos e a cultivar, aplicaram-se ferramentas quimiométricas de Análise dos Componentes Principais (PCA) e Análise de Agrupamentos Hierárquicos (HCA), pelas quais foi possível diferenciar as amostras das folhas secas de acordo com suas procedências. Os extratos metanólicos também foram submetidos a ensaios de citotoxicidade in vitro para 04 linhagens de células tumorais humanas (HCT-8, HL-60, SF-295 e MDA-MB- 435), obtendo-se CI50 25,13 μg/mL, na linhagem HL-60 para a amostra da cultivar (EPAMIG). Este resultado está dentro do intervalo proposto pelo National Institute of Cancer, USA (NCI) para considerar extratos como promissores. A atividade biológica destes extratos também foi avaliada sobre o desenvolvimento de Spodoptera frugiperda, principal praga do milho, apresentando 60% de mortalidade larval.

Physic nut (Jatropha curcas L.) is an important crop due to its ability of storing high content of oil in the seeds, which can serve as raw material for biodiesel production. Because of the presence of toxic constituents like phorbol esters (PEs) and curcins, the seed cake produced as a result of oil extraction cannot be utilize for animal feed. Development of the genotypes better suited for the industrial applications and biodiesel production as well as with lower level of toxic constituents is being hampered by a lack of understanding about the a) proteins related to the biosynthesis and degradation of fatty acids (FAs) and triacylglycerides (TAGs), b) role of proteins deposited during seed development and c) proteins related to the synthesis and storage of toxic compounds during seed development. Agreeing with this, we have performed the anatomical analysis of the developing seeds of J. curcas, followed by the proteome analysis of the endosperm isolated from the seeds of J. curcas at five different developmental stages, which resulted into the identification of the 1517, 1256, 1033, 752 and 307 proteins, from Stage 6, 7, 8, 9 and 10, respectively, summing up to a total of 1760 proteins. Proteins with similar expression pattern were grouped into five different clusters and protein quantification based on spectral counts was determined. Besides identification of the proteins involved in the biosynthesis and degradation of the FAs and TAGs, we also identified a large number of proteins involved in the metabolism of the carbohydrates, which are important for supplying energy and carbon source for the synthesis of TAGs in heterotrophic seeds. Among the members of different classes of seed storage proteins (SSPs), we have identified four SSPs named as nutrients reservoir, which in contrast to the other SSPs showed decreasing deposition pattern during seeds development and revealed to have special role during seed development. In addition, peptidases belong to different mechanistic classes were identified, which have a range of functions, highlighting the role in reserve mobilization during germination. Isoforms of curcin were also identified in this proteome analysis which were absent in our previous proteome analysis of the other tissues from these seeds, suggesting that the deposition of these toxic proteins only occur in the endosperm. Similarly, several enzymes involved in the biosynthesis of diterpenoid precursors were identified in this proteome analysis but, like in our previous proteome analysis of the other tissues from J. curcas seeds,we were unable to identify any terpene synthase/cyclase, enzymes responsible for the synthesis of PEs, which collectively suggesting that the synthesis of PEs may not occur in seeds of this plant. In conclusion, the strategy used here enabled us to provide a first in depth proteome analysis of the endosperm from J. curcas developing seeds, which along with providing information regarding important aspects of the seed development, also set the foundation of a proteomic approach to study biotechnologically important plant species.
PinhÃo manso (Jatropha curcas L.) à uma cultura importante devido à sua habilidade em armazenar alto conteÃdo de Ãleo nas sementes, as quais podem servir como matÃria-prima para a produÃÃo de biodiesel. Devido à presenÃa de constituintes tÃxicos como Ãsteres de forbol e curcina, a torta da semente produzida como resultado da extraÃÃo do Ãleo nÃo pode ser utilizada na alimentaÃÃo animal. O desenvolvimento de genÃtipos mais adequados a aplicaÃÃes industriais e à produÃÃo de biodiesel assim como apresentando baixos nÃveis de constituintes tÃxicos està sendo prejudicado pela falta de entendimento sobre a) proteÃnas relacionadas a biossÃntese e degradaÃÃo de Ãcidos graxos e triacilglicerÃis, b) o papel de proteÃnas depositadas durante o desenvolvimento da semente e c) proteÃnas relacionadas à sÃntese e reserva de compostos tÃxicos durante o desenvolvimento da semente. Diante disso, nÃs realizamos uma anÃlise anatÃmica de sementes em desenvolvimento de J. curcas, seguido por uma anÃlise proteÃmica do endosperma isolado de sementes dessa espÃcie em cinco diferentes estÃgios de desenvolvimento, o que resultou na identificaÃÃo de 1517, 1256, 1033, 752 e 307 proteÃnas, dos estÃgios 6, 7, 8, 9 e 10, respectivamente, somando um total de 1760 proteÃnas. ProteÃnas com padrÃo de expressÃo similar foram agrupadas em cinco grupos diferentes e a quantificaÃÃo das proteÃnas baseada na contagem dos espectros foi determinada. AlÃm da identificaÃÃo das proteÃnas envolvidas na biossÃntese e degradaÃÃo de FAs e TAGs, nÃs identificamos um grande nÃmero de proteÃnas envolvidas no metabolismo de carboidratos, as quais sÃo importantes para o fornecimento de energia e fontes de carbono para a sÃntese de TAGs em sementes heterotrÃficas. Entre os membros de diferentes classes de proteÃnas de reservas de sementes (SSPs), nÃs identificamos quatro SSPs denominadas reservatÃrios de sementes, que em contraste as outras SSPs mostraram decrÃscimo no padrÃo de deposiÃÃo e revelaram ter um papel especial durante o desenvolvimento da semente. Em adiÃÃo, peptidases pertencentes a diferentes classes mecanÃsticas foram identificadas destacando o papel da mobilizaÃÃo de reservas durante a germinaÃÃo. Isoformas da curcina ausentes em nossas anÃlises proteÃmicas prÃvias de outros tecidos da semente foram identificadas sugerindo que a deposiÃÃo dessas proteÃnas tÃxicas sà ocorre no endosperma. Similarmente, vÃrias enzimas envolvidas na biosÃntese de precursores de diterpenÃides foram identificadas nessa anÃlise proteÃmica, mas como em nossas prÃvias anÃlises proteÃmicas de outros tecidos de sementes de J. curcas, nÃs nÃo fomos capazes de identificar sintases/ciclases de terpenos, enzimas responsÃveis pela sÃntese de PEs, o que coletivamente sugere que a sÃntese desses compostos pode nÃo ocorrer nas sementes dessa planta. Em conclusÃo, a estratÃgia utilizada nos fornece a primeira anÃlise proteÃmica profunda do endosperma de sementes em desenvolvimento de J. curcas, o que alÃm de fornecer informaÃÃes sobre aspectos importantes do desenvolvimento da semente, tambÃm estabelece a base para uma pesquisa proteÃmica com o objetivo de estudar espÃcies vegetais importantes biotecnologicamente.

A propagação do pinhão manso pode ser realizada via semente e vegetativa através de estacas e micropropagação. Quando realizada via semente, as plantas são mais vigorosas, porém iniciam a produção tardiamente. Utilizando-se estacas têm-se uma produção precoce e mantém as características da planta mãe, no entanto, verifica-se menor crescimento vegetativo inicial. Já a técnica da micropropagação pode produzir mudas sadias, em escala comercial com um curto período. Com isso objetivou-se com esta pesquisa, desenvolver protocolos para a propagação do pinhão manso via sementes, estaquia e micropropagação, visando à obtenção de mudas de qualidades. O projeto foi dividido em três partes: a primeira parte objetivou-se produzir plantas através de sementes, onde foram realizados testes pré-germinativos em diferentes substratos (comercial, vermiculita, areia); a segunda parte utilizou-se estacas, onde foram testadas partes do ramo (apical, mediana, basal) e diferentes substratos (comercial Bioplant®, vermiculita, areia) em duas épocas, agosto/2011 e março/2012. Na terceira parte foram desenvolvidas técnicas de micropropagação, envolvendo as etapas de assepsia dos explantes in vitro através do controle de contaminação utilizando concentrações de cloro ativo e tempo de imersão, problemas frequentes que inviabilizam a utilização da micropropagação para espécies lenhosas, como o pinhão manso; etapa de desenvolvimento onde estudou concentrações da citocinina 6-Benzilaminopurina (BAP) e dos sais do meio de cultivo Murashige e Skoog (1962) (MS); e a fase de enraizamento in vitro utilizando concentrações do ácido indol butírico (AIB).
