基因芯片技术在植物耐盐基因研究中的应用

Nowdays,the problems of food security and environment have been restricting the development of human society. More and more serious soil salinization is threating the limited soil that the human survive with.The key problem needed to solve for plant breeding is improving the salt-tolerance of crops by analyzing the mechanism of plant salt tolerance and researching plant salt tolerance related genes.however,salt tolerance is a quantitative character which involves coordinating of many genes.So it can't reveal the mechanism of plant salt tolerance and the interaction of genes only by a single gene expression analysis.The genechip with the charcaters of high fiux, easy operation and high reliability can reveal the expression and regulation of a large number of genes.We have a review of the application of genechip in salt tolerance mechanism analysis and genes expression in rice, soybean and wheat and have a outlook about the application proepects in the field.
