Plant Growth Hormone Regulated Transcription Factors and Promoters Thereof

摘要

Methods for obtaining plants with decreased responses to auxins by reducing exprssion of endogenous MYB77 genes in plants are disclosed. Also disclosed are methods of using plant MYB77 transcriptional promoter sequences to drive expression of heterologous genes in select plant cells at select times in plant development. Methods of obtaining plants with decreased lateral root formation when grown under nutrient deficient conditions by reducing expression of endogenous MYB77 and transgenic plants with reduced expression of endogenous MYB77 genes in are also provided.
