Abstract:

Abiotic stresses are important factors that affect the growth and development of plant and crop yield. In order to alleviate their negative effects, the study tries to elucidate the material basis for cotton stress resistance and its physiological functions at the molecular level, and at the same time through genetic engineering to conduct stress related gene recombination, which has become a hot spot in cotton stress resistance study. This paper reviewed the mechanism of cotton resistance to abiotic stresses, and recent research progress in the osmoregulation related genes, functional protein genes and transcriptional factor related genes. The paper also outlined the gene resources exploited though genetic engineering, aiming at providing some thoughts and references for future studies on cotton stress resistance.

Key words: abiotic stress, stress tolerance genes, genetic engineering, cotton
