甘蔗近缘野生种蔗茅的研究进展和利用潜力
Research Progress and Utilization Potential of Wild Sugarcane Species Erianthus fulvus Ness
摘要
Abstract
The efficient use of wild sugarcane relatives is critical for expanding genetic diversity and accelerating the breeding process of modern sugarcane cultivars.Erianthus fulvus Ness,a wild species of sugarcane,represents not only a valuable germplasm resource for sugarcane breeding but also an important system for studying genome evolution and functional gene analysis within the sugarcane complex.Since the 1980s,significant progress has been made in the collection and characterization of E.fulvus germplasm,as well as the development of new sugarcane varieties exhibiting enhanced drought resistance and cold tolerance through intergeneric hybridization.Recent studies have elucidated the physiological and molecular mechanisms underlying agromomically favorable traits,including high sugar content,cold tolerance and drought resistance.To further explore the molecular basis of these excellent traits and their application potential in sugarcane breeding,this review summarizes current research on E.fulvus,with a focus on the genetic diversity,genome evolution and sucrose biosynthesis and transport pathways,and also evaluates its potential as a model organism and biofuel crop.Additionally,we examine the molecular responses of E.fulvus to low temperature and drought stresses,discuss the existing challenges in its research and utilization,and propose the future development direction.关键词
