Description
Milieu de culture pour tissus méristématiques et procédé de culture de ces tissus en condition non stériles
La présente invention concerne un milieu de culture pour tissus méristématiques, un procédé de culture de ces tissus en condition non stériles et les plantes obtenues à l'aide de ce procédé.Culture medium for meristematic tissues and method of culturing these tissues in non-sterile condition
The present invention relates to a culture medium for meristematic tissues, a method for culturing these tissues in non-sterile conditions and the plants obtained using this method.
Il est bien connu que la culture d'embryons somatiques de plantes et de jeunes plantes qui en sont issues nécessite l'utilisation d'un milieu de culture sucré. Cependant la présence de sucre attire les microorganimes tels que champignons, bactéries, algues, protozoaires et virus. Or une protection maximale est nécessaire pour assurer la culture, la croissance et l'obtention de plantules puis de plantes saines. Cet inconvénient est évité en effectuant la culture en conditions stériles, ce qui alourdit et complique l'expérimentation. Une autre voie serait d'ajouter des antibiotiques. Cette solution a été tentée par exemple pour la culture d'embryons de carotte cf Synseeds 1993 Ch; 15 F.Molle et coll.) mais s'est révélée inutilisable en raison d'une phytotoxicité inacceptable provoquant le blocage de la croissance des embryons. On a utilisé des fongicides à large spectre tels que le carbendazime ou le benomyl mais ils ne se sont révélés non phytotoxiques qu'à faibles doses, pour lesquelles leur action était tout à fait insuffisantes. Il en est de même avec certaines combinaisons de fongicides et d' antibiotiques de la littérature. It is well known that the culture of somatic embryos of plants and young plants derived therefrom requires the use of a sweet culture medium. However the presence of sugar attracts microorganisms such as fungi, bacteria, algae, protozoa and viruses. However, maximum protection is necessary to ensure the cultivation, growth and obtaining of seedlings and healthy plants. This disadvantage is avoided by performing the culture in sterile conditions, which increases and complicates the experiment. Another way would be to add antibiotics. This solution has been attempted, for example, for culturing carrot embryos cf Synseeds 1993 Ch; F.Molle et al.) But was found to be unusable due to unacceptable phytotoxicity causing the blockage of embryo growth. Broad-spectrum fungicides such as carbendazim or benomyl have been used, but they have been shown to be non-phytotoxic at low doses, for which their action was quite inadequate. It is the same with certain combinations of fungicides and antibiotics of the literature.
11 est donc connu que le problème d'une protection efficace des milieux de culture pour embryons somatiques dans des conditions non stériles reste entier et qu'il y a un besoin pour résoudre cette difficulté. Cette difficulté résulte d'une plus grande sensibilité, en conditions non stériles, des embryons par rapport aux graines, des embryons aux produits phytosanitaires et au fait qu'il faut également protégér ces embryons contre l'action de micro-organismes autres que les pathogènes. It is therefore known that the problem of effective protection of somatic embryo culture media under non-sterile conditions remains unresolved and that there is a need to resolve this difficulty. This difficulty results from the greater sensitivity, in non-sterile conditions, of embryos compared to seeds, from embryos to plant protection products and the fact that these embryos must also be protected against the action of microorganisms other than pathogens. .
La demanderesse a maintenant découvert un nouveau milieu de culture permettant de résoudre ce problème avec obtention d'une protection efficace par l'utilisation de matières actives protectrices particulières. Par protection efficace on entend une protection d'au moins 10% de la surface du milieu. The applicant has now discovered a new culture medium to solve this problem with obtaining effective protection by the use of specific protective active ingredients. Effective protection means protection of at least 10% of the surface of the medium.
Plus particulièrement l'invention concerne milieu de culture pour tissus méristématiques, en condition non stériles, comprenant un milieu sucré, caractérisé en ce qu'il contient en outre une quantité efficace et non phytotoxique d'au moins une matière active protectrice contre les micro-organismes choisie dans le groupe comprenant une matière active fongicide p' phytosanitaire et une matière active bactéricide rémanente. More particularly, the invention relates to a culture medium for meristematic tissues, in non-sterile conditions, comprising a sweet medium, characterized in that it additionally contains an effective and non-phytotoxic amount of at least one protective active ingredient against microorganisms. organisms selected from the group consisting of a phytosanitary fungicidal active ingredient and a residual bactericidal active ingredient.
Au sens de la présente description, on entend par "tissu méristématique" tout tissu végétal, ou ensemble de cellules végétales, capable, lorsqu'il est mis dans des conditions convenables, de se développer jusqu'à former une plante entière ou partie de plante entière. For the purposes of the present description, the term "meristematic tissue" any plant tissue, or set of plant cells, capable, when put under suitable conditions, to develop to form an entire plant or plant part whole.
Sous l'expression "tissu" on inclut toute sorte de tissus végétaux, notamment: le tissu somatique, les masses pro-embryogènes (connu en anglais sous le nom de proembryogenic masses, l'embryon somatique, le tissu zymotique, la graine, le germe, le bourgeon adventice, les pousses, le primordium de tige (connu en anglais sous le nom de shoot primordium), les analogues de protocorn (connus en anglais sous le nom de protocorn like body), le tissu connu en anglais sous le nom de green spot, les cellules germinales et semences naturelles (connues en anglais sous le nom de germ line), les jeunes plants.Under the term "tissue" are included all kinds of plant tissues, including: somatic tissue, pro-embryogenic masses (known in English as proembryogenic masses, somatic embryo, zymotic tissue, seed, germ, weed bud, shoots, stem primordium (known as shoot primordium), protocorn analogues (known in English as protocorn like body), tissue known in English as of green spot, germ cells and natural seeds (known in English as germ line), young plants.
Les végétaux concernés par l'invention sont de nature les plus diverses et incluent les cultures vivrières telles que le riz, le blé, I'orge, le maïs, le soja ; les cultures légumières telles que le céleri, le persil, la salade, le chou-fleur, la carotte, I'aubergine, la tomate,

Onion, garlic, ginger, strawberries, melons, asparagus; food and / or industrial crops such as canola, sugar cane, sugar beet, tobacco, coffee; cultures for medical purposes such as belladonna, ginseng; ornamental crops such as chrysanthemums, gladiolus, lilies, orchids, amaryllis, geraniums, begonia, Cape violets, poinsettia; trees or tree species or shrubs such as conifers, palms, fruit trees, vines, deciduous trees, and others.
Le tissu méristématique peut être sec, déshydraté ou sous forme hydratée jusqu'à 100% d'humidité. The meristematic fabric can be dry, dehydrated or hydrated form up to 100% moisture.
Au sens de la présente invention, on entend par "micro-organismes" ceux appartenant aux classes des champignons, bactéries, algues, virus et protozoaires. For the purposes of the present invention, the term "microorganisms" means those belonging to the classes of fungi, bacteria, algae, viruses and protozoa.
De meme, on entend par "milieu de culture" tout milieu, solide (par exemple milieu gélosé) ou liquide (solution nutritive), éventuellement adsorbés sur des substrats de culture tels que laine de roche, acétate de cellulose, fibres polyethylène, polyuréthannes, noix de coco, permettant la culture de tissus méristématiques, in vitro ou en serre, éventuellement avec relargage contrôlé des matières actives. Le milieu peut être statique, apporté une fois pour toutes ou renouvelé régulièrement sous forme, soit d'un flux continu, soit d'un flux discontinu (batch). Similarly, the term "culture medium" means any medium, solid (eg agar medium) or liquid (nutrient solution), optionally adsorbed on culture substrates such as rockwool, cellulose acetate, polyethylene fibers, polyurethanes, coconut, allowing the culture of meristematic tissues, in vitro or in greenhouse, possibly with controlled release of active ingredients. The medium can be static, provided once for all or regularly renewed in the form of either a continuous flow or a discontinuous flow (batch).
Le sucre est présent dans milieu selon l'invention à une concentration comprise en général entre 0,1 mu et 200 g/I et de préférence comprise entre 5 g/I et 200 g/I. The sugar is present in a medium according to the invention at a concentration generally ranging from 0.1 to 200 g / l and preferably from 5 g / l to 200 g / l.
Par "matière active phytosanitaire", on entend essentiellement une matière active fongicide. Celle ci est de préférence choisie dans le groupe comprenant les dérivés du cuivre, les dérivés de l'oxyquinoléine, les dithiocarbamates, les dicarboximides, les phénylpyrroles, les triazoles. De manière particulièrement préférée, on utilise des fongicides choisis dans le groupe comprenant l'oxychlorure de cuivre, I'oxyquinoléine, l'oxyquinoléate de cuivre, le mancozèbe, le manèbe, le thirame, le fludioxonil, et l'iprodione. By "phytosanitary active ingredient" is meant essentially a fungicidal active ingredient. This is preferably selected from the group consisting of copper derivatives, oxyquinoline derivatives, dithiocarbamates, dicarboximides, phenylpyrroles, triazoles. Particularly preferably, fungicides selected from the group consisting of copper oxychloride, oxyquinoline, copper oxyquinoleate, mancozeb, maneb, thiram, fludioxonil, and iprodione are used.
Dans la présente demande les noms de matières fongicides sont les noms communs (cf Pesticide Manual 1995). In the present application, the names of fungicidal substances are the common names (see Pesticide Manual 1995).
De manière particulièrement préférée, le milieu contient au moins deux fongicides. In a particularly preferred manner, the medium contains at least two fungicides.
Un autre aspect important de l'invention est que ces fongicides sont utilisés en quantité non phytotoxique pour le tissu méristématique, c'est à dire à des concentrations, qui peuvent être plus faibles que celles habituellement utilisées pour la protection des plantes entières. Plus précisément le milieu contient de 0,1 mu à 10go, et de préférence de 1 mg à I g/I de matière active fongicide. Another important aspect of the invention is that these fungicides are used in a non-phytotoxic amount for the meristematic tissue, that is to say at concentrations, which may be lower than those usually used for the protection of whole plants. More precisely, the medium contains from 0.1 to 10 g, and preferably from 1 mg to 1 g / l of fungicidal active ingredient.
Plus particulièrement et de préférence, la concentration est comprise entre:
- 0,1 et 10 mg/l pour les dérivés du cuivre,
- 0,1 et 10 mg/l pour les dérivés de l'oxyquinoléine,
- 0,1 et 10 mgA pour les dérivés dithiocarbamiques,
- 0,1 et 10 mg/l pour les dérivés phénylpyrroles,
- 0,1 et 1000 mgA pour les dérivés dicarboximides.More particularly and preferably, the concentration is between:
- 0.1 and 10 mg / l for copper derivatives,
0.1 and 10 mg / l for the oxyquinoline derivatives,
0.1 and 10 mgA for the dithiocarbamic derivatives,
0.1 and 10 mg / l for the phenylpyrrole derivatives,
- 0.1 and 1000 mgA for the dicarboximide derivatives.
Par "matière active bactéricide", on entend essentiellement une matière active bactéricide ou bactériostatique. Celle-ci peut appartenir à une famille quelconque, la préference étant donnée au dérivés de l'acide salicylique tel que par exemple l'acide salicylique, l'acide acétylsalicylique, les salicylates ou encore aux thiazolines, telle que par exemple la 1,2-benzisothiazoline-3-one, voire des antibiotiques. By "bactericidal active ingredient" is meant essentially a bactericidal or bacteriostatic active ingredient. This may belong to any family, the preference being given to salicylic acid derivatives such as for example salicylic acid, acetylsalicylic acid, salicylates or thiazolines, such as for example 1,2 benzisothiazolin-3-one, or even antibiotics.
Le milieu peut contenir plusieurs bactéricides. The medium may contain several bactericides.
La concentration en matière active bactéricide est de 0,1 à 100 mg/l, et de préférence de 0,1 à 100 et de préférence de 0,1 à 10 mg/l de matière active. The concentration of bactericidal active ingredient is from 0.1 to 100 mg / l, and preferably from 0.1 to 100 and preferably from 0.1 to 10 mg / l of active material.
Plus particulièrement et de préférence, la concentration est comprise entre:
- 0,1 et 10 mgA pour les dérivés de l'acide salicylique,
- 0,1 et 5 mg/l pour la 1,2-benzisothiazoline-3-one. More particularly and preferably, the concentration is between:
0.1 and 10 mgA for the salicylic acid derivatives,
0.1 and 5 mg / l for 1,2-benzisothiazolin-3-one.
Le milieu selon l'invention peut encore contenir d'autres matières actives ou adjuvants à condition que les quantités soient non phytotoxiques pour les tissus méristématiques. Pour la fabrication du milieu ci-dessus, il suffit de mélanger les ingrédients décrits avec la base du milieu. Si le milieu final est solide, le mélange se fait à chaud en phase liquide pour être ensuite versé dans des récipients de laboratoire tels que des boites de Petri ou Magenta. The medium according to the invention may also contain other active substances or adjuvants provided that the amounts are non-phytotoxic for the meristematic tissues. For the manufacture of the above medium, it is sufficient to mix the ingredients described with the base of the medium. If the final medium is solid, the mixture is hot in the liquid phase and then poured into laboratory containers such as Petri dishes or Magenta.
Les conditions de culture et les résultats seront mieux compris à l'aide des exemples suivants, sans que ceux-ci limitent la portée de l'invention. The culture conditions and the results will be better understood by means of the following examples, without these limiting the scope of the invention.

The stock solution is made by diluting the active ingredient, formulated or not, in a Heller medium without saccharose. The culture medium is made by adding a fraction of the stock solution to the basal medium, which contains 15 g of sucrose.
Chaque solution nutritive gélosée est répartie dans des boîtes Magenta (Sigma, USA) à raison d'environ 40 ml par boîte. Les boîtes Magenta sont amenées en mini-serre qui sont ouvertes sans précautions particulières en conditions non stériles, à raison d'une boîte par milieu et par mini-serre. Each nutrient solution is distributed in Magenta boxes (Sigma, USA) at a rate of approximately 40 ml per box. The Magenta boxes are brought to the mini-greenhouse, which are opened without any particular precautions in non-sterile conditions, one box per medium and one mini-greenhouse.
La température est d'environ 20"C, avec une humidité relative modulable de 30 à 70% par système brouillard. Les serres permettent d'utiliser l'éclairage naturel mais, si celui-ci est trop faible, on utilise un éclairage d'appoint fixe à l'aide de lampes à vapeur de sodium haute pression de 400 watts. The temperature is about 20 ° C, with a relative humidity adjustable from 30 to 70% by fog system.The greenhouses allow to use the natural lighting but, if it is too weak, one uses a lighting of fixed booster using 400 watt high pressure sodium lamps.
Quatorze jours après la mise en place, la surface du milieu de culture contaminée par les micro-organismes est mesurée dans chaque boîte ainsi que le nombre de colonies qui se sont développées. Fourteen days after the establishment, the surface of the culture medium contaminated by the microorganisms is measured in each box and the number of colonies that have developed.
