    摘要: The present invention relates to a vector for introducing a desired gene into a plant, wherein a selectable marker gene introduced into a plant cell along with a desired gene is optionally removable from the DNA such as chromosome or the like where it exists and functions, then disappeared the function thereof after its expression, and the expression of the selectable marker gene and the disappearance of the function thereof are detectable by morphological change of the tissue derived from the plant cell into which the selectable marker gene is introduced. Also, the present invention constitutes a vector using a morphological abnormality induction gene as a selectable marker gene, while putting a removable DNA element under control of an inducible promoter, wherein the morphological abnormality induction gene is positioned such that it behaves integrally with the removable DNA element, and wherein a desired gene is positioned such that it does not behave integrally with the removable DNA element.

    摘要: A process for producing a plant is described, which comprises the step of culturing a tissue of a plant belonging to the genus Populus, the section Leuce, thereby regenerating the plant via an adventitious bud, wherein the adventitious bud is differentiated from the cultured tissue using an adventitious bud differentiation medium having nitrogen source concentrations of from 1 to 15 mM as ammonia-nitrogen and from 15 to 50 mM as nitrate-nitrogen.
