摘要:
Disclosed is a method of transforming monocotyledons which necessitates only a short period from the transformation to the regeneration of a whole plant as compared with the conventional methods, thus reducing the frequency of occurrence of mutants, and can be generally applied to the plants for which any system of regenerating the whole plants from protoplasts has not been established, and in which the material to be used can be readily prepared without any particular apparatuses. The present invention provides a method for transforming monocotyledons comprising transforming scutellum of an immature embryo of a monocotyledon with a bacterium belonging to genus Agrobacterium containing a desired gene, which immature embryo has not been subjected to a dedifferentiation treatment, to obtain a transformant.
摘要:
The invention relates to a method for transforming a monocotyledonous plant. The time required from transformation to regeneration of a plant is shorter using the inventive method so that the frequency of emergence of mutants is smaller than the conventional methods. The inventive method may be generally applied even to the plants for which a regeneration method from a protoplast to a plant has not been established, and with which the preparation of the material to be subjected to the method is easy. That is, the present invention provides a method for transforming a monocotyledonous plant, comprising contacting a cultured tissue of said monocotyledonous plant during dedifferentiation thereof obtained by culturing an explant on a dedifferentiation-inducing medium for less than 7 days with a bacterium belonging to the genus Agrobacterium containing a super binary vector having the virulence region of a Ti plasmid, left and right border sequences of T-DNA of a Ti plasmid or an Ri plasmid of a bacterium belonging to the genus Agrobacterium, and a desired gene located between said left and right border sequences.
