谷子扩展蛋白与品种抗旱性关系的研究
The relationship between expansin gene family and drought stress in foxtail millet
摘要
Abstract
Obj ective]As an important part of plant cell wall,expansin exists widely in almost every plant genome.Ex-pansin can increase the flexibility of the cell wall and plays an important role in physiological process of plant growth and stress.In order to explore drought genetic resources in foxtail millet.[Methods]1 6 expansin genes of foxtail millet were analyzed.[Results]They were classified into 4 subfamilies (EXPA,EXPB,EXPLA and EXPLB),through the promoter analysis,we found a number of responsive elements related to drought stress,including drought response MYB binding site MBS,ABA response element ABRE,and so on.The expression levels of expansin genes in two fox-tail millet varieties GG (drought-resistant variety)and JF1 6 (drought-sensitive variety)were analyzed,the results showed that their expression levels were different significantly in different varieties under drought stress.[Conclusion] According to cis-acting elements of promoter and phylogenetic tree of expansin genes,we found out there are no signifi-cant relationship between drought stress and these results.But these results provide a foundation for further study on the relationship between expansin genes and stress resistance in foxtail millet.关键词
