Application of soybean nac transcription factor gene GmNAC4 in regulating soybean grain size and / or drought resistance

Abstract

The application belongs to the technical field of genetic engineering, and particularly relates to a soybean NAC transcription factor gene GmNAC4 The application discloses the application of the soybean NAC transcription factor gene in regulating soybean kernel size and / or drought resistance GmNAC4 The soybean NAC transcription factor gene has a dual function of "negative regulation of kernel size and positive regulation of drought resistance", the expression of the soybean NAC transcription factor gene is induced by dehydration stress, and thus a molecular switch mechanism of yield-drought resistance trade-off is disclosed, a key target point is provided for soybean molecular design breeding, and high yield and drought resistance can be simultaneously improved through time and space specific expression regulation or modular decoupling strategies, and a traditional breeding bottleneck is broken through.
