Gene Details:

• Gene ID: HORVU.MOREX.r3.7HG0658790
• Gene Symbol: HvHK1
• Gene Name: HISTIDINE KINASE 1
• Genome: MorexV3_pseudomolecules_assembly
• Species: Hordeum vulgare

Functional Descriptions:

• HvHK1 encodes a histidine kinase and is specifically expressed in the syncytial endosperm at the maternal–filial boundary.
• The RNAi-mediated downregulation of HvHK1 disrupts ETC differentiation, impairs endosperm development and reduces grain weight.
• Demonstrate that HvHK1 functions as a central regulator of ETC specification in the young barley endosperm by orchestrating cytokinesis, cell polarity and wall formation in the syncytial domain at the maternal–filial conjunction of grains.
• Repression of HvHK1 impairs cell specification in the central ETC region and the development of transfer cell morphology, and consecutively defects differentiation of adjacent endosperm tissues.
