Differential Genetic Responses to Drought Stress in C3 and C4 Plants: Insights for Enhancing Crop Resilience
Research reveals that drought stress disrupts photosynthesis by down-regulating key genes in C3 (wheat) and C4 (sorghum) plants, with wheat exhibiting greater susceptibility, highlighting potential genetic targets for improving drought tolerance in crops.
Hormonal Regulation of Sugar Transport Drives Salt Tolerance Through Strategic Resource Allocation in Sorghum
Salt tolerance in sorghum is closely linked to hormone-regulated sugar transporter expression that controls resource allocation between roots, stems, and grains during development, enabling stress-resilient genotypes like Della to delay sodium translocation and sustain metabolic balance.
