PYL-PYR proteins were recently described as receptors for the plant hormone abscisic acid (ABA) and as inhibitors of the phosphatases ABI1 and ABI2 in the presence of ABA. The crystal structures of PYL2 in its apo and ABA-bound forms and of the ternary complex PYL1–ABA–ABI1 have now been solved, providing insight into ABA sensing and signaling.


Until print versions of AOP papers are published, they should be cited in the style "Author(s) Nature Structural & Molecular Biology advance online publication, day month year (doi:10.1038/nsmbXXXXX)". Once the print version (identical to the AOP) is published, it should be cited as follows: "Author(s) Nature Structural & Molecular Biology volume, page (year); advance online publication, (doi:10.1038/nsmbXXXXX)".
