Arabidopsis	At2g29380	Probable protein phosphatase 2C 24.	No verified direct reference in this release
Rice	Os01g0846300	Probable protein phosphatase 2C 9.	No verified direct reference in this release
Rice	Os03g0268600	Together with ABI5, PYL5 and SAPK2, is part of an abscisic acid (ABA) signaling unit that modulates 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.; 2012; DOI: 10.1093/jxb/err338; PMID: 22071266; https://pubmed.ncbi.nlm.nih.gov/22071266/
