Gene Details:

• MSU gene ID: LOC_Os09g15430
• RAPdb gene ID: Os09g0323100
• Gene Symbol: OsHTAS
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Further dynamic expression analysis demonstrated that OsHTAS ( a ) was actively responsive to 45 degrees C high temperature stress compared with the OsHTAS ( b ) allele.
• The genetic analysis of F(1) and F(2) offspring derived from the cross between HT54 and HT13, a heat-sensitive breeding line, reveals that the heat tolerance of HT54 was controlled by a dominant major locus, which has been designated as OsHTAS (Oryza sativa heat tolerance at seedling stage).
• The RING Finger Ubiquitin E3 Ligase OsHTAS Enhances Heat Tolerance by Promoting H2O2-Induced Stomatal Closure in Rice.
• OsHTAS was responsive to multiple stresses and strongly induced by exogenous ABA.
• OsHTAS modulated H2O2 accumulation of shoots thus altered the stomatal aperture status of rice leaves, and promoted ABA biosynthesis.
