Nucleic acid molecule and vector inducing endosperm development in seed plant without fertilization, transgenic seed plant capable of developing endosperm without fertilization and method for constructing same

摘要

As a means for artificially inducing functional endosperm in a seed plant without fertilization, provided is a nucleic acid molecule that contains a base sequence encoding a polypeptide capable of inducing endosperm development, said nucleic acid molecule being to be transferred into the genome of the seed plant and expressed therein so as to induce endosperm development in the seed plant without fertilization.
