Gene Details:

• Gene ID: Zm00001eb096040
• Gene Symbol: ZmHP2 hp2
• Gene Name: histidine-containing phosphotransfer protein2
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• A naturally occurring non-synonymous SNP variant enhances the interaction between ZmRR1 and ZmHP2, conferring maize plants with a salt-hypersensitive phenotype.
• ZmHP2-mediated signaling increases ZmMATE29 transcription under salt stress conditions. ZmMATE29 encodes a tonoplast-localized Cl− transporter that promotes shoot Cl− exclusion, likely by compartmentalizing Cl− into the vacuoles in root cortex cells.
• Loss of ZmHP2 function confers cytokinin-insensitive and salt-hypersensitive phenotype.
