Drought is one of the most adverse environmental factors affecting wheat yield and quality. Under drought stress, target genes in wheat could be activated and expressed to produce drought-induced proteins, enabling plants to actively adapt to drought, and to maintain survival and yield formation. So, studying on drought-induced proteins and the related genes is essential for future genetic engineering and crop breeding of drought-resisting and water-saving. The objective of this research is to analyse the gene expression profile of wheat under drought stress, and to detect the fragments related to drought-resistant gene expression. Genes induced by drought stress in the seedling of Xinjiang spring wheat cultivar Xinchun 6 at 2-leaf stage were analysed by cDNA-AFLP techniques.
