Abstract
En 中文
Saline soil and drought are among the most devastating abiotic stresses constraining sugarcane (Saccharum spp.) production globally; with soil salinity affecting over 1; 125 Mha worldwide and drought causing severe yield losses in tropical and subtropical agroecosystems. As a glycophytic C4 crop supplying ~80% of the world’s sugar; sugarcane is particularly vulnerable; with threshold salinity tolerance at a mere 1.7 dS m–1 electrical conductivity (EC). This review integrates recent developments in the physiological; biochemical; and molecular responses of sugarcane during stress conditions. Under salinity; photosynthetic CO2 efficiency; chlorophyll integrity; source–sink partitioning; reactive oxygen species (ROS) metabolism; phytohormone signaling; and osmolyte accumulation are altered based on the sugarcane cultivars and cultivation regions. Under drought; stomatal regulation; root hydraulics; abscisic acid (ABA) cascades; and the expression of dehydrin and late embryogenesis abundant (LEA) proteins govern tolerance. At the molecular level; ion-transporter genes (SOS pathway); DREB/ERF transcription factors; aquaporins; and small RNAs constitute central regulatory hubs. Mitigation strategies; including agronomic interventions; exogenous osmoprotectants; plant growth-promoting rhizobacteria; biochar amendment; and advanced breeding tools such as CRISPR/Cas9; marker-assisted selection; and transgenic approaches; are comprehensively discussed for sustainable sugarcane production.
