Annotated Information
Gene Symbol
- Os02g0187800 <=> OsPYL/RCAR10, OsPYL1, OsPYL10, PYL1, PYL10
Function
- OsPYL is a positive regulator of the ABA signal transduction pathway in seed germination and early seedling growth
- Abscisic acid (ABA) is a phytohormone that positively regulates seed dormancy and stress tolerance.[1][2][3]
Phenotypic analysis
- 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.
- Constitutive expression of OsPYL/RCAR5 increases expression of the ABA-responsive genes under ABA treatment
Expression
- This gene is related to the expression of ABA metabolism and its signaling pathways.
- Proteins related to ABA signaling pathways may have a higher expression variation among different organs or stress responses in comparison with those of ABA metabolism. [2]
Evolution
- It is the common ancestor of many species such as A. thaliana, Arabidopsis lyrata, Populustrichocarpa, Oryza sativa, Selaginella moellendorffii, and Physcomitrella patens.
- Twelve ABA receptor orthologs named OsPYL1–12 in Oryza sativa (OsPYLs) are identified. OsPYL1 corresponds to Os10g0573400 which is showed in the following chaters. [3]
- Phylogenetic relationships in orthologous cluster 7 including ABA receptor genes. An orthologous cluster (OC) is defined to have genes diverged in each species from a gene in the common ancestor of these six species. [2]
