ＳＫＩＮ基因默化质体，以及包含该质体的转型植物细胞及基因转殖植物;SKIN GENE SILENCING PLASMID, AND TRANSFORMED PLANT CELL AND TRANSGENIC PLANT COMPRISING THE SAME

摘要

本发明系关于一种SKIN基因默化质体和包含该质体的转型植物细胞。前述SKIN基因默化质体包含：启动子；两个DNA片段，其系取自源于SKIN1或SKIN2之cDNA的一个DNA片段，并以正义和反义的方向排列；以及第三个DNA片段，其系插在前述两个DNA片段之间。SKIN是水稻生长和产量的负向调控因子，且内源性SKIN表现的减少会增加水稻的产量。本发明还涉及包含前述SKIN基因默化质体的转型植物细胞以及基因转殖植物。; two DNA fragments, which are obtained from one DNA fragment derived from the cDNA ofSKIN1or SKIN2and arranged in sense and antisense orientation; and a third DNA fragment inserted between the two DNA fragments.SKINis a negative regulator of the growth and yield of rice, and decreasing the expression of endogenous SKIN increases the yield of rice. The present invention also relates to a transformed plant cell and a transgenic plant comprising theSKINgene silencing plasmid.
