Gene Chips for Expression of Stress-tolerant Genes in Rice
-
摘要: 水稻是世界上最重要的粮食作物之一,全世界50%以上的人口以水稻为主食,导致水稻减产的主要原因之一是受逆境胁迫的影响。为了提高水稻的抗逆性,目前国内外许多实验室正致力于水稻抗逆机制的研究。与抗逆相关的单一基因较难以揭示植物复杂的抗逆机制,而基因芯片技术却可以揭示大量基因表达和调控的情况,使得多基因的调控研究成为可能。本文主要综述了近年来基因芯片技术在水稻受逆境胁迫条件下基因的表达情况。Abstract: Rice(Oryzae sativa) is one of the most important crops in the world.It is the staple for more than 50% of the global population.Adversity stress is one of the main reasons for the rice to suffer a poor yield.To improve the resistance to stress in rice,it is necessary to firstly understand its mechanism.Many laboratories in China and abroad are indeed working on it.However,due to the highly complex nature,no single gene study can be expected to reveal the entire mechanism in plants.Currently,the technology of gene chips might offer a new tool for the studies of the genes expression and regulation associated with the stress resistance.Recent progress in the application is summarized.
