Rice stamen specific expression system protease gene, stamen specific expression promoter of the gene, production method of male infertility introduced rice using suppression of expression of the gene

摘要

The present invention relates to a novel gene encoding cysteine protease expressed specifically in rice anther, an anther-specific promoter of the gene and a method for producing male sterile rice by suppressing expression of the gene. The rCysP1 gene of the present invention is a novel gene encoding cysteine protease that is expressed in rice anther and thus involved in pollen development. Therefore, suppression of the gene expression makes it possible to prepare male sterile rice available to control of seed production because the suppression results in pollen generation in rice. In addition, the above gene of the present invention is available to other Gramineae and provides an advantage to use antagonistic traits, which can be shown by over-expression.
