Gene Details:

• MSU gene ID: LOC_Os07g06980
• RAPdb gene ID: Os07g0164100
• Gene Symbol: HDA704
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Rice histone deacetylase HDA704 positively regulates drought and salt tolerance by controlling stomatal aperture and density.
• HDA704 enhances drought and salt tolerance via stomata-regulated mechanism.
• In this study on rice, we identified the RPD3/HDA1-type histone deacetylase HDA704 as a positive regulatory factor in drought and salt tolerance.
• HDA704 was induced by drought and salt stresses.
• Overexpression of HDA704 in transgenic rice promoted stomatal closure, decreased the number of stomata and slowed down the rate of water loss, consequently resulting in increased drought and salt tolerance.
• By contrast, knockdown of HDA704 in transgenic rice decreased stomatal closure and accelerated the rate of water loss, leading to decrease drought and salt tolerance.
• Collectively, these findings reveal that HDA704 positively regulates drought and salt tolerance by repressing the expression of DST and ABIL2.
• HDA704 negatively regulates stomatal aperture and density, repressing the transcription of DST and ABIL2 by histone deacetylation modification.
