SUGAR CANE FLOWERING CONTROL TECHNIQUE

摘要

PROBLEM TO BE SOLVED: To provide a technique capable of the efficient cross breeding of plants, particularly, sugar cane and the one closely related thereto.SOLUTION: The invention is any one DNA selected from: (a) DNA made of a specified base sequence; (b) DNA made of a base sequence in which one or more bases are deleted, substituted, added or inserted in a specified base sequence, and having activity of specifically promoting gene expression in a mature leaf; (c) DNA made of a base sequency having a sequence identity of 90% or more with respect to the specified base sequence and having activity of specifically promoting gene expression to a mature leaf; and (d) DNA which hybridizes under a stringent condition with DNA made of a sequence complementary to the specified base sequence, and having activity of specifically promoting gene expression in a mature leaf.
