Abstract

The invention discloses an early anther specific promotor and an application thereof. The promoter is the promoter of a rice gene LOC_Os05g42240; the promoter can be used for controlling the specific expression of a target gene in such cells as anther primordium, tapetum and microspore cells in an anther early development stage of a plant; and the promoter is applicable to researches in the aspects of plant breeding and gene function analysis.

Description

technical field

[0001] The invention belongs to the technical field of plant genetic engineering, and in particular relates to a high-efficiency promoter sequence specifically expressed in the early development stage of rice anthers and the application of the promoter in plant transgenesis. Background technique

[0002] Rice (Oryza sativa L.) is a monocot model crop for the study of plant gene function, and it is also one of the most important food crops in the world. However, with the increase of population and the decrease of arable land and a series of problems, how to effectively increase the yield of rice at the unit level has become a long-term research goal in rice breeding. At present, the application of heterosis can not only improve the ability of crops to resist diseases and insect pests, but also effectively improve crop quality and increase crop yield.

[0003] In the utilization of heterosis, the methods of restoring the fertility and maintaining the sterility...
