Full textIn the perspective of a second Green Revolution, aiming, unlike the first one, to enhance yields of crops in a low fertility context, the strategies used by plants for an optimal uptake of soil nutrients are at the core of the problem. To solve it and identify ideal breeds among the genetic diversity of crops, plant root systems, their development and their architecture, are called upon to play the leading role. The variability among secondary roots appears as a crucial feature for the optimality of soil exploration and acquisition of mobile and immobile resources, but this phenomenon remains poorly understood. The work presented in this thesis focuses on the lateral roots of maize (Zea mays L.) and attempts to unravel the processes at the origin of intrinsic variations in lateral root development. It relies notably on the phenotyping of individual lateral roots at an unprecedented scale, tracking the daily growth of thousands of them at a high spatial resolution, in order to characterize precisely the spatio-temporal variations existing both between and within root individuals. Individual growth rate profiles were analyzed with a statistical model that identified three main temporal trends in growth rates leading to the definition of three lateral root classes with contrasted growth rates and growth duration. Differences in lateral root diameter at root emergence (originating at the primordium stage) were likely to condition the followed growth trend but did not seem enough to entirely determine lateral root fate. Lastly, these lateral root classes were randomly distributed along the primary root, suggesting that there is no local inhibition or stimulation between neighbouring lateral roots. In order to explain the origin of the observed differences in growth behaviour, we complemented our study with a multi-scale characterization of groups of lateral roots with contrasted growth at a cellular, anatomical and molecular level. A particular focus is set on the analysis of cell length profiles in lateral root apices for which we introduced a segmentation model to identify developmental zones. Using this method, we evidenced strong modulations in the length of the division and elongation zones that could be closely related to variations in lateral root growth. The regulatory role of auxin on the balance between cellular proliferation and elongation processes is demonstrated through the analysis of mutant lines. Ultimately, variations in lateral root growth are traced back to the allocation of carbon assimilates and the transport capacity of the root, suggesting that a feedback control loop mechanism could play a determinant role in the setting out of contrasted lateral root growth trends

Full textThere are two approaches, cultural and cinematographic, in the study of Yasujiro Ozu’s films. In response to the conflict between the two, and to view the richness and depth of Ozu’s works from a new perspective, I propose to return to Zen Buddhism ideas, which are deeply rooted in Japanese culture and aethetics. Ozu’s style of “neither attaching nor quitting" comes from the Buddhist idea that "Color is Emptiness”. "Color" means "phenomenon"; Buddhism asserts that in the universe of Emptiness, all phenomena are changeable and temporary, namely, impermanent. In my research, I will analyze how Ozu, by arranging elements of emptiness and fullness, reveals to us that impermanence is the reality of universe and life, and inspires us to cherish our companies in the impermanent life. We will find that it is the interpenetration of emptiness and fullness, of absence and presence, which give rise to the tension in Ozu’s films. And these films are the manifestation of “the Color of Emptiness”

O conhecimento da diversidade de fungos micorrízicos arbusculares em raízes de plantas cultivadas é um pré-requisito para o manejo efetivo e a sustentabilidade de sistemas agrícolas. O objetivo deste trabalho foi determinar qualitativa e quantitativamente as comunidades de FMA em agrossistemas plantados com milho, em Pernambuco. Na primeira etapa do trabalho foram realizadas coletas em três estações experimentais do Instituto Agronômico de Pernambuco: uma localizada em área úmida (Zona da Mata - Itambé) e duas no semiárido (Agreste – Caruaru; Sertão - Serra Talhada) em 2010 e 2011. A análise morfológica dos esporos permitiu a diferenciação de 57 espécies de FMA, das quais duas novas para a ciência. Maior densidade de esporos ocorreu na área do agreste, que apresentou menor riqueza de espécies de FMA. Na área mais úmida foi registrada maior riqueza. A estrutura das comunidades de FMA diferiu entre os locais, segundo o teste de procedimento de permutação multi-resposta (MRPP), em função de diferenças nos atributos químicos e granulométricos dos solos. Duas novas espécies foram descritas: Fuscutata aurea, registrada em Itambé e Paraglomus pernambucanum, encontrada em amostras coletadas em Caruaru e Serra Talhada. Foi proposta uma nova combinação para Paraglomus (P. bolivianum) e revisada a ocorrência mundial dos representantes de Paraglomus e Pacispora. Na segunda etapa do estudo (2012) foram realizadas coletas em três propriedades privadas irrigadas, localizadas também nas Zonas da Mata, Agreste e Sertão, respectivamente nos municípios de Igarassu, Passira e Serra Talhada, em dois períodos de desenvolvimento do milho (60 – floração e 90 dias – colheita). A análise morfológica dos esporos revelou a presença de 43 espécies de FMA. Também foram realizadas análises moleculares da raiz, sendo sequenciados 433 clones do SSU rDNA, dos quais 93 pertencentes a indivíduos das ordens Diversisporales, Gigasporales, Glomerales e Paraglomerales. Dentre os 259 clones do LSU rDNA, 153 corresponderam a gêneros incluídos em Diversisporales, Gigasporales e Glomerales. Os demais clones foram relacionados a outros grupos de eucariotas. Em todas as áreas predominaram representantes de Acaulospora e Glomus. Houve diferença significativa entre as áreas para a maioria dos atributos químicos e composição granulométrica dos solos. A estrutura das comunidades de FMA foi significativamente diferente entre as áreas, de acordo com a ordenação (NMS) e o método estatístico (PERMANOVA). A maior porcentagem de raiz colonizada ocorreu em plantas coletadas em Igarassu (Mata), enquanto a maior riqueza de espécies foi encontrada em solos de Passira (Agreste). A diversidade de FMA no solo difere daquela encontrada no sistema radicular de plantas colonizadas. Representantes dos gêneros Claroideoglomus, Diversispora, Dominikia, Intraornatospora, Redeckera e Rhizoglomus não foram identificados no solo rizosférico, enquanto Ambispora e Paradentiscutata foram observados apenas a partir da análise morfológica dos esporos presentes no solo, não sendo obtidas sequências desses gêneros. A rizosfera de plantios de milho, mesmo em áreas com diferentes características edafoclimáticas, abriga diversificada comunidade de FMA, com dominância dos gêneros Glomus e Acaulospora. O estádio fenológico do milho pode influenciar a diversidade, e a composição das comunidades de FMA pode ser melhor determinada com o uso conjunto de ferramentas moleculares e morfológicas para identificação dos fungos.
The effective management and sustainability of agricultural systems depends on the knowledge of the diversity of AMF in roots of cultivated plant. The aim of this study was to determine qualitatively and quantitatively the AMF communities in corn agrosystems, in Pernambuco, Northeast Brazil. In the first stage of this work collections were carried out in three experimental stations of the Agronomic Institute of Pernambuco: one located in an Atlantic rain forest area (Forest Zone - Itambé) and two in semiarid areas ("Agreste" - Caruaru and "Sertão" - Serra Talhada), in 2010 and 2011. Fifty seven taxa were found, two of which are new species. In the “agreste” area we found higher number of spores and lower richness of AMF species. The highest species richness was registered in the most humid area. The structure of the AMF communities differed among the sites, according to the multi-response permutation procedure test (MRPP), due to differences in chemical and physical soil attributes. The new species described are: Fuscutata aurea, registered in Itambé (humid area) and Paraglomus pernambucanum found in samples from the semiarid areas. A new combination for Paraglomus (P. bolivianum) was proposed, and a survey of the global occurrence of Paraglomus and Pacispora was performed. In the second stage of this study (2012), samples were taken in three private properties, with irrigated fields of corn also located in the three areas: rain Forest (Igarassu), "Agreste" (Passira) and "Sertão" (Serra Talhada). The collections were performed in two periods of corn development (60 days – flowering, and 90 days - harvest). The morphological analysis revealed the presence of 43 AMF taxa. Molecular root analyses were performed, and 433 clones sequenced (SSU rDNA), of which 93 belonged to individuals of the orders Diversisporales, Gigasporales, Glomerales and Paraglomerales. Among the 259 clones of the LSU rDNA, 153 corresponded to genera included in Diversisporales, Gigasporales and Glomerales. The remaining clones were related to other eukaryotic groups. Species of Acaulospora and Glomus predominated in the areas. Significant differences among the areas for most chemical and physical soil attributes were found. The structure of the AMF communities was significantly different among the areas, according to the ordination (NMS) and the statistical method (PERMANOVA). The highest percentage of root colonization occurred in plants collected in Igarassu (Forest), while the highest species richness was found in Passira soils (Agreste). The diversity of AMF in the soil differs from that found in the root system of colonized plants. The genera Claroideoglomus, Diversispora, Dominikia, Intraornatospora, Redeckera and Rhizoglomus were only detected through molecular analysis, while Ambispora and Paradentiscutata were observed just from morphological analysis. The rhizosphere of corn crops in areas with different soil and climatic characteristics has a diverse community of AMF, with dominance of Glomus and Acaulospora species. The growth stage of corn plants can influence the diversity of AMF fungi, which decreased in the rhizosphere of older plants. The simultaneous use of morphological and molecular approaches can improve the knowledge about the composition of AMF communities.

Full textThe objective of the thesis was to develop a method for predicting the tissue origin of particles in powders of lignocellulosic plants using the autofluorescence properties of cell walls. The internode under the ear of maize stems was used as a model. Fluorescence macroscopy has been validated for acquiring large multispectral images with representative fields of view about 1 cm². A chemometric approach by multispectral image analysis was applied to build the predictive model of tissues based on their autofluorescence properties observed in stem sections. The calibration set consisted of 40 transverse and longitudinal sections taken at different positions from 10 stems of the same variety. Variability of fluorescence in tissues was found preponderant compared to inter and intra-stems variability by supervised analysis. In order to take into account all the fluorescence variability of the tissues in maize stem without any a priori, the prediction model was built from an unsupervised clustering of all the pixels from the 40 images. The large number of pixels led to the development of a multi-scale clustering method based on K-means method using image pyramids. The model made it possible to identify the main tissues of the stem: lignified and non-lignified parenchyma, sclerenchyma sheaths in vascular bundles in the pith and in the rind, epidermis, fibers of xylem. The next step will be to test the prediction model on powders

Full textMaize is one of the most widely grown crops in the world and is grown for grain for human consumption, feedstock for cattle and more recently biofuel. When used as fuel, the most important agronomic trait is digestibility which is dictated by cell wall composition and structure. Many studies have been undertaken in order to improve cell wall digestibility and have essentially focused on the lignin biosynthetic pathway. During my PhD research, we have shown that a mutation in ZmCCR1 (Cinnamoyl-CoA reductase 1), key enzyme in lignin biosynthesis, modified lignin structure which in turn resulted in an increase in digestibility. Beyond lignification per se, my studies focused on the identification of other potential parameters influencing digestibility at the cellular level. This is especially pertinent in maize since its stem biomass is made up of different several lignified tissues and cell types. By combining cell wall biochemistry on laser microdissected (LMD) lignified tissues, with histological studies, we have been able to show that in highly contrasting lines (Cm484 and F98902) the lignified cell types patterning and in particular, the amount and cell wall composition are critical factors in determining maize digestibility

Full textThe beginning of crop growth is influenced by soil temperature and water content near the surface. We have developed a model that predicts the local temperature and water content surrounding the seed using easily available meteorological data. Our global sensitivity analysis helped us identify the components of the model with the largest contribution to the output uncertainty. After calibration, the model showed less than 10 % relative error for temperature and water content at 30 cm. In standard sowing conditions in north-western Switzerland, the emergence was better predicted when using our simulated seed bed temperature than air temperature, the classical proxy variable. Combining the emergence model with soil temperature simulation, an accurate prediction of emergence was achieved. This work is an example of applying complex biophysics model for understanding an agronomic problem. The results of this work will participate in optimising breeding efforts for cold-tolerant crop varieties. Future investigations should consider a finer modelling of processes for evaporation and emergence

RESUMO – O melhoramento vegetal, além de buscar as características de interesse, busca também otimizar o processo. Sendo assim, quando há correlação entre as características de interesse e uma de fácil avaliação, abre-se a vertente para a seleção indireta. A utilização de sensores na agricultura possibilita a avaliação sem contato físico, podendo ser uma nova ferramenta na seleção indireta, visando otimizar tempo, mão de obra, custo e o processo. Objetivou-se estudar a relação entre o Índice de Vegetação por Diferença Normalizada (NDVI) e os caracteres agronômicos, na seleção indireta em milho e selecionar os genótipos superiores utilizando técnicas multivariadas. O experimento foi conduzido na segunda safra de 2016, sendo realizadas as medições de NDVI via sensor ativo terrestre, a cada 15 dias após a emergência das plântulas e as avaliações agronômicas de campo considerando os caracteres: altura de planta, altura da espiga principal, acamamento, quebramento, estande e produtividade. O conjunto de variáveis obtidas foram submetidas as análises multivariadas de fatores e de componentes principais. A análise de fatores detectou, no primeiro fator, correspondências positivas entre as variáveis, altura de planta, altura de espiga e produtividade, no segundo fator NDVI-80, NDVI-95 e acamamento mais quebramento e no terceiro fator NDVI-15 e estande. Os gráficos biplots gerados pelos componentes principais, juntamente com análise de ganho de seleção permitiram identificar o genótipo 3 como o mais promissor, por apresentar baixo acamamento mais quebramento, baixo valor de NDVI-80 e NDVI-95 e alta produtividade em relação a este experimento. A partir de todos os resultados concluise que é possível usar o NDVI, via sensor ativo terrestre, como técnica promissora na seleção indireta, para acamamento, quebramento e predição do estande em milho.
ABSTRACT - The plant breeding look beyond the characteristics of interest, look to optimize process, so when there is a correlation between the characteristics of interest and one of easy evaluation, a strand is opened for indirect selection. The use of sensors in agriculture makes possible to evaluate without physical contact and it can be a new tool in the indirect selection, aiming to optimize time, work, cost and optimize process. The objective of this study was to analyse the relationship between Normalized Difference Vegetation Index (NDVI) and agronomic traits, in the indirect selection and to select superior genotypes of maize by multivariate analyse. The experiment was conducted in the second crop of 2016, and NDVI was measurements by an active sensor every 15 day after seedling and field agronomic traits were evaluated considering the following characteristics: plant height, ear height, stalk lodging, stalk breakage, stand and yield. With these data were processed the factor analyzes, principal component and gain selection. The factor analysis detected positive correspondences between the variables, plant height, ear height and yield with factor 1; NDVI-80, NDVI-95 and stalk lodging plus stalk breakage with factor 2; NDVI- 15 and stand with factor 3. The graphics biplots generated by the principal components with gain selection analyze allowed to identify the best genotype, where we could identify the genotype 3 as the most promising, because it present lower lodging plus breakage stalk, low value of NDVI-80 and 95, and high yield in relation to this experiment. From all results it is concluded that it is possible to use the NDVI, by active sensor, as a promising technique in the indirect selection, for stalk lodging, breakage and stand in maize.
