Gene Details:

• Gene ID: HORVU.MOREX.r2.3HG0228480
• Gene Symbol: HvAKT1
• Gene Name: Inwardly rectifying K+ channel 1
• Genome: MorexV3_pseudomolecules_assembly
• Species: Hordeum vulgare

Functional Descriptions:

• Overexpression of HvAKT1 improves drought tolerance in barley by regulating root ion homeostasis and ROS and NO signaling.
• The expression of HvAKT1 was significantly up-regulated by drought stress in the roots of XZ5—a drought-tolerant wild barley genotype.
• Silencing of HvAKT1 resulted in significantly decreased biomass and suppressed K+ uptake in root epidermal cells under drought treatment.
• Our results highlight the importance of HvAKT1 for root K+ uptake and its pleiotropic effects on root H+-ATPase, and H2O2 and NO in response to drought stress, providing new insights into the genetic basis of drought tolerance and K+ nutrition in barley.
