Unraveling the K+ transporter gene family in rice: evolution, subcellular localization, K+ uptake activity, and transcriptional responses to salt stress
Rice is a global staple food crop, and its yield is seriously limited by soil salinity. The high-affinity K+ transporter/K+ uptake permease/K+ transporter (HAK/KUP/KT) family of potassium transporters plays a pivotal role in K+ homeostasis and plant salt tolerance. However, their systematic characterization and functio...
