Genome-Wide Characterization of the Sugarcane PIP Gene Family and Functional Validation of ScPIP2-70 in Low-Potassium Stress Tolerance
This study comprehensively elucidates the evolutionary dynamics and spatiotemporal expression profiles of the sugarcane PIP gene family and uncovers the novel pleiotropic function of ScPIP2-70 in mediating low-K+ stress tolerance, providing critical theoretical support and candidate gene resources for breeding “potassium-efficient” sugarcane cultivars via modern biotechnology.
