Promoter expressing foreign gene in root and shoot apex

摘要

The present invention provides a rice catalase B promoter for inducing expression specifically in at least one site of roots and stem apices. By using this promoter, it is possible to synthesize a resistance substance against nematodes or soil pathogens in roots; synthesize a substance promoting the development of roots in the roots; produce a gene recombinant plant in which expression of a selective marker in the redifferentiated plant body is limited to roots when the plant is young, so as to suppress the expression when the plant is matured; or the like. Further, the capability of expression in stem apices can be used to develop a technique for suppress gene expression in vigorously proliferating cells.
