• Publication
  • A rice orthologue of the ABA receptor, OsPYL/RCAR5, is a positive regulator of the ABA signal transduction pathway in seed germination and early seedling growth, 2012, J Exp Bot.
  • Overexpression of PYL5 in rice enhances drought tolerance, inhibits growth, and modulates gene expression, 2014, J Exp Bot.
• Genbank accession number

• Key message
  • Transgenic rice plants expressing OsPYL/RCAR5, a PYL/RCAR orthologue of rice, were found to be hypersensitive to ABA during seed germination and early seedling growth
  • A rice orthologue of the ABA receptor, OsPYL/RCAR5, is a positive regulator of the ABA signal transduction pathway in seed germination and early seedling growth
  • The constitutive expression of OsPYL/RCAR5 in rice driven by the Zea mays ubiquitin promoter induced the expression of many stress-responsive genes even under normal growth conditions and resulted in improved drought and salt stress tolerance in rice
  • A rice ABA signalling unit composed of OsPYL/RCAR5, OsPP2C30, SAPK2, and OREB1 for ABA-dependent gene regulation was further identified, via interaction assays and a transient gene expression assay
  • This suggests that, although exogenous expression of OsPYL/RCAR5 is able to improve abiotic stress tolerance in rice, fine regulation of its expression will be required to avoid deleterious effects on agricultural traits
  • OsPYL/RCARs thus are considered to be good candidate genes for improvement of abiotic stress tolerance in crops
  • This work demonstrates that the cytosolic ABA receptor OsPYL/RCAR5 in O
  • Previous work identified OsPYL/RCARs as functional ABA receptors regulating ABA-dependent gene expression in Oryza sativa
• Connection
  • OsDET1, OsPYL~RCAR5, OsDET1 Modulates the ABA Signaling Pathway and ABA Biosynthesis in Rice, These findings suggest that OsDET1 deficiency disturbs the CDD complex, which is responsible for ABA receptor (OsPYL) degradation, eventually leading to ABA sensitivity in rice
