Molecular characteristics and regulatory effects of dwarfing Rht genes in Triticum aestivum L.

ABSTRACT:

Background

Application of Rht dwarfing genes has significantly enhanced plant lodging resistance and harvest index. However, the numerous members of Rht genes, particularly newly cloned genes in recent years, remain poorly understood in integrated analysis of their expression patterns under stress conditions, allelic interaction effects, and molecular regulatory mechanisms, these limit our comprehensive exploration of Rht gene regulatory network, and hinder the potential application in wheat genetic improvement.

Results

This study comprehensively analyzed the characteristics of Rht family members. The results showed that there were 27 Rht genes in wheat, with only 10 cloned members. Collinearity of Rht genes was observed in wheat genomes, as well as cross-species collinearit
