Genetic Analysis and Improvement Strategies of Protein Content in Rice Seeds

摘要

Enhancing the nutritional quality of food crops is a way to improve human nutrition and health.Grain protein content(GPC)is an important nutritional quality trait for rice and many other crops.Therefore,it will be very significant to increase GPC and improve rice quality.This paper mainly reviewed the genetic studies GPC in rice,mapping and cloning of QTLs and genes associated with GPC.However,little is known about the molecular mechanism and gene function related to GPC in rice.Thus,here we put forward the genetic strategy by gene pyramiding or molecular marker assisted selection to improve GPC and nutritional quality in rice.This review could provide important information for genetic improvement of grain nutritional quality of rice.
