Full textMicropropagation of apple (Pyrus malus L. ) is realized from the apex isolated for the herbaceous stem. We have studied the factors which influence the rate of multiplication and rooting in order to improve the yields and to master this in vitro culture technique. In multiplication medium containing benzyladenine (4,4 m) and IBA (0,49 m) has permitted to increase the number of axillary buds at the temperature of 27°C. Addition of phloridzine in the medium has produced 9,7 axillary buds per explants, after 7 weeks of culture. The root inducing medium having IAA or IBA gives the best percentage of rhizogenese. Optimal rooting response is obtained with the rooting medium containing phloroglucinol. Adventitious organogenesis and somatic embryogenesis has been exploited to promote new techniques of multiplication. The neoformation of buds has been obtained from internodal explants. TIBA (1 m) with BA (4,4 m) has permitted the induction of buds. The adventitious buds and somatic embryos have been obtained separately or simultaneously from zygotic embryos. The high concentration of auxin and benzydadenine stimulate adventitious regeneration. Immature explants react more vigorously for adventitious organogenesis then the mature explants. Origin of neoformed adventitious buds or embryos is situated at the level of epidermal or sub-epidermal cells

Full textThe cultivated apple (Malus X domestica Borkh, 2n = 2x = 34) is an allogametic perennial, propagated by vegetative methods. It has a high degree of heterozygosity, and a complex genomic constitution. It can be described as a secondary polyploid. The production of haploid plants in such species therefore presents multiple interests concerning cytogenetics and mutagenesis as well as breeding of cultivars. Three haploidization methods have been studied in this thesis: in vitro androgenesis by anther culture, in vitro gynogenesis by unfertilized ovule culture, and in situ parthenogenesis induced by irradiated pollen followed by in vitro culture of immature embryos. - Anther culture has produced a number of androgenetic embryos in three genotypes ('Topred', 'Starking' and 'Rr') and androgenetic calli in three other genotypes ('Golden Delicious', 'R8-16' and 'Doubled Haploid'). Cytological observations showed that androgenetic development has been induced mainly by a diversion of the 1st pollinic mitosis leading to 2 identical nuclei. Our studies have shown that several factors could influence in vitro androgenesis: * The genotype plays a determining role in androgenetic embryo formation * A cold pretreatment (≥ 5 weeks at 2 to 6°C) applied to the flower bud before anther culture has proved to be necessary for embryo formation; 2 to 6 weeks of the same treatment can significantly increase the rate of callogenesis. .

Full textThanks to its clonal propagation (grafting), apple tree is an interesting model for epigenetic studies. Indeed, phenotypic variability can be observed within the same variety, suggesting a potential contribution of epigenetic mechanisms. At the beginning of this thesis, the mechanisms of transmission of epigenetic marks, such as DNA methylation, were still little studied in perennial plants.To better understand how epigenetic marks are transmitted and contribute to phenotypic traits, we have defined two main axes of research: (i) UsingCRISPR-Cas9 technology we have created apple mutant lines in order to obtain a systematic decrease in DNA methylation. (ii) In order to assess the transmission of epigenetic marks during sexual and asexual reproduction, we compared the epigenomes of adult trees, grafts and seedlings obtained by self-fertilization on a model doubled-haploid line. Analyses at the whole epigenome level indicated that there is no overall change in DNA methylation between an adult tree, a grafted tree and an apple seedling. However, we were able to detect specific regions that are differentially methylated (DMRs). Interestingly, more DMRs were detected between seedlings and grafted tree or adult tree than between the tree and grafted tree, suggesting that the tree and grafted tree are closer epigenetically. Our phenotypic, transcriptomic and methylome analysis results confirm the difference between adult trees and seedlings. They also confirm that grafted tree is at the interface between juvenility and maturity

Full textVerticillium wilt in potato is caused by some imperfect fungi of the genus Verticillium particularly Verticillium dahliae, Kleb. In order to obtain resistant or tolerant clones to this pathogen, we studied three varieties of potato varied in their susceptibility to this parasite and three strains of this fungus by using in vitro culture techniques. Based on the three strains of Verticillium dahliae. Je, cultivated in vitro, we clarified some methods which allowed the production of the filtrates and their conservation without loosing the toxicity. The susceptibility of these varieties to filtrate treatments was tested in vitro and we noted a good correlation with their susceptibility to the fungi in the greenhouse conditions. The study showed that the interaction host-pathogen was modulated by two important factors: the environment and the Ume which mean the physiological age of plant. We cannot find any correlation between the toxicity of m v1tro filtrate and the pathogenesis of the fungus in the greenhouse or in the field, unless the two factors were perfectly controlled. The study also revealed one morphogenetical particularity of the tolerant varieties (as in BF 15 and Katahdin): the growth acceleration in inoculated plants by the fungus which gives them a higher precocity. The regenerated plants were produced from calli after or without the pressure of selection imposed by the filtrate of one strain. These regenerated clones will be then tested in vitro for their susceptibility to the filtrate

Full textAmong Rhodophyta and Chlorophyta, some species have a dermocosmetic interest. For the time being seaweeds are harvested from wild populations leading to problems of supply, heterogeneous biomass and preservation of natural resources. In order to produce an algal biomass of quality throughout the year different systems of micropropagation were evaluated for seven species. For four of them systems of in vitro propagation based on their morphological, physiological and biochemical properties and their in vitro behavior were developed. A slow-growing stock culture of one Chlorophyta was initiated by cuttings and the physicochemical parameters were identified allowing to the establishment of fast-growing cultures. Protoplasts were produced only from these fast-growing cultures. A closed-loop system of micropropagation was elaborated from ‘in vitro seaweed beds’ of another Chlorophyta produced from protoplasts. Tissue culture on solid medium of two Rhodophyta showed their morphogenetic potentialities in particular the regeneration of shoots. The system of in vitro propagation from protoplasts is also possible for one of these Rhodophyta, the production of protoplasts was improved but only the sporadic regeneration of the cell wall was observed. Protoplasts were also obtained from two other Rhodophyta suggesting the feasibility of developing protoplast technology provided to bypass the intolerance of the immersion for the one and to elaborate the sterilization treatment for the other

Full textDuring the last decade micropropagation of trees proved to be a very interesting tool especially for breeding program. Therefore it appeared to be necessary to micropropagate black aider in order to improve vegetative propagation and also in order to study rejuvenation processes. Alder micropropagation was first described in 1983 but only with juvenil matértal. Studies of the different parameters influencing micropropagation enabled to improve the protocole and first results concerning micropropagation of old trees are rather encouraging. New methods, especially apex tissue culture were also used and were successfull with juvenile material. Trying to understand cellular differenciation and the processes of rejuvenation is a very thorough study and only hints were studied. Nonetheless some were rather unusual, such as flavonoïd spectra and mitochondrial activities. This study al so underlines the hurdles met with micropropagation and one may conclude that micropropagation of trees is not ready for industrial scale

Full textIn the present work the possibilities of multiplication through in vitro cutting of three yam cultivars of high economical value, have been studied, and the field behaviour of the in vitro plantlets thus obtained has been observed. The primary explants must be taken from young parts of plants cultivated in green house. Auxins are favorable for rooting of cuttings: a cytokinin like benzyladenin is rather favorable to shoot organogenesis. D. Cayenensis rotundata cv V17/2 give the best multiplication ration with the medium 169 derived from M. S. By C. Martin, reaching 164 000 after 12 months; but this cultivar proved to be also the most difficult to transfer to the field. With the lengthening of daylight a production of V17/2 seed-tuber reaches a theorical ratio of 484 000 over two years. D. Trifida cv INRA 5-20 and D. Alata cv Belep are more hardy refering to their transfer to the field, which however need a good mist. INRA 5-20 has seemingly its field behavior improved through the simple in vitro cutting technic

Full textIn vitro multiplication of globe artichoke is based on shoot apices culture and micropropagation. However, this method cannot be extended to mass production. To try and find new methods, we considered two different approaches somatic embryogenesis and adventive organogenesis. A great number of different explants were cultivated to find out which organs and which stages are the most suitable for callogenesis or organogenesis. Neither organic nor embryogenic calli were obtained. On the other band, rhizogenesis was obtained from organs such as cotyledons and stamens ;caulogenesis was obtained from young receptacles and isolated flowers. Lt was possible to regenerate plants from shoots produced by these last two organs. In a second, step, we studied the way of obtaining shoots from isolated flowers in vitro and their micropropagation. This technique uses a sequence of media, the first being inductive. Histological studies showed that adventive structures originated from axil of sepals. Even though the number of organogenic flowers may be important, only a few produced good quality shoots. This process allows regeneration of virus and bacteria free plants. Yield and conformity problems were considered. Potential applications of this new technique are pointed out

Full textApple trees are the target of a lot of pests and fungal diseases, responsible for many economic losses. Farmers treat these micro-organisms mainly with pesticides. Plant-protection products are today very controversial. French and European authorities control their use by means of numerous regulations. Therefore, an alternative solution with a low remanence must be found in order to limit fungal diseases. The aim of this thesis is to evaluate the innovative process efficiency based on the use of ozonated water against four fungal species: Venturia inaequalis, Botrytis cinerea, Neofabraea alba and Phytophthora syringae. Firstly, this work of thesis verified the ozone antifungal action on spores suspensions of the four fungal species and on different stages of development of V.inaequalis spores. According to the species and stages of development considered, a difference of sensibility was detected. Moreover, alteration of the membrane, due to ozone action, was observed thanks to several experimentations: quantification of phospholipids peroxidation, spore observations with Scanning Electron Microscopy and with Optical Microscopy after staining. Secondly, the ozonated water effects on seedlings previously contaminated by V.inaequalis spores were evaluated. This study confirmed the anti-fungal action of water containing ozone. It was also observed the importance of the water and of ozone quantities supplied. These quantities must be controlled to optimize the antifungal action of the treatment. These results validated the ozone application as a fungicide alternative of use of pesticides. Additional researches will be made concerning the treatment modalities: the aim is to transfer the technology from the laboratory to the orchard

Full textThe vegetative propagation of Pinus merkusii in vitro had been carried out starting from plants issued from either seed germination, or from plantlets of ungerminated seeds. Four steps of different treatments are necessary to realize this technique: the obtaining and development of buds, leaflets growth, root establishment, and transplantation. Bud formation and rhizogenesis require previous induction of growth substances (BAP only or in combination with NAA for bud formation, NAA for rhizogenesis), while leaflets growth and root elongation are promoted by the presence of active charcoal in simple mineral medium. At green-house conditions, the transplantation in the vermiculite shows good results. In this case the root system of cutting is better developed than those obtained from seeds

Full textIn order to increase the yield of sugarcane somatic embryos, the culture media factors were studied. Agarose and Silver nitrate had a positive effect. Genetical factors appeared most important than physiological factors. Thus, the yield was increased from 5% to 50% allowing the first positive trials of encapsulation of somatic embryos, and the application to cell and protoplast cultures. The very compact structure of embryogenic calli remained an obstacle. The establishment of microcallus suspension cultures has been allowed only by direct initiation in liquid medium of embryogenic expiant. These suspensions were able to regenerate plants and to give a great quantity of protoplasts. Some cytological studies and biochemical analysis were carried out to compare embryogenic and non embryogenic calli. Callus structure and cellwall behavior appeared very different. A lignification of embryogenic callus was pointed out. Some very important qualitative and quantitative differences were exhibited in endogenous growth regulators and particularly in ABA and cytokinin metabolism. A specific protein of embryogenic calli and some differences of isozymes and amino-acids were also showed. The whole of these results are discussed in taking the results of in vitro culture into account for a best understanding of gramineous somatic embryogenesis

Full textDeveloping tissue culture for Helianthus annuus L. Provides new options for gene or organelle transfer to overcome natural sterility barriers and producing new nucleo-cytoplasmic combinations. Ln order to introduce genes by direct gene transfer or by protoplasts fusion we developed a protoplast culture. Cell division has been obtained from hypocotyl protoplasts of Helianthus annuus and leave protoplasts of Helianthus petiolaris. The addition of agarose to the protoplast culture medium was an absolute requirement for substaining cell division and microcalli formation. Hypocotyls protoplasts gave rised to embryoid like-structures similar to those observed in hypocotyl liquid cultures. Ln the resultant culture a mixed population of calli and proembryoid structures was noticed. Factors affecting the developmental pattern of embryogenesis from protoplats are studied. The frequeny of embryoid like-structure formation reached 30 % of the total plated protoplasts when they are cultivated in a solidified medium supplemented with BAP (4,4 μM) et de l'ANA (5,4 μM). For sunflower, embryogenesis occurs from hypocotyl protoplasts, indicating that cells when converted to protoplasts are potentially responsive to redetermination via embryogenesis
