- Abstract
bHLH is a superfamily in plant kingdom, whose members participate in the processes of plant growth, development, and stresses resistance. But up to now, the functions of bHLHs in cotton are less studied and reported. This paper took Gossypium hirsutum as material, seperates and clones gene-GhbHLH4, and carried out initial analysis on its function. The results showed that there are abundant stress-response relevant cis-elements in the promoter region of gene GhbHLH4. The leaves and roots of transgenic GhbHLH4 Arabidopsis plants were wider and longer than WT. Transgenic GhbHLH4 plants grew normally under long-time treatment of 150 mmol/L NaCl. The results of this study has laid a foundation for thorough understanding the molecular mechanism of salt tolerance in GhbHLH4 gene.
