• Symbol: OsHTAS
• MSU: LOC_Os09g15430
• RAPdb: Os09g0323100

• A dominant major locus in chromosome 9 of rice Oryza sativa L. confers tolerance to 48 degrees C high temperature at seedling stage, 2013, J Hered.
• The RING Finger Ubiquitin E3 Ligase OsHTAS Enhances Heat Tolerance by Promoting H2O2-Induced Stomatal Closure in Rice, 2015, Plant Physiol.

Genbank accession number

• 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
