Besides the sole prototypical G protein alpha subunit gene, GPA1, the Arabidopsis thaliana genome has three extra-large GTP-binding protein (XLG)-encoding genes: XLG1 (At2g23460), XLG2 (At4g34390) and XLG3 (At1g31930). |

Epub 2005 Jan 21. Recently, we have shown that the enzyme responsible for S1P production, kinase (SphK), is stimulated by the phytohormone abscisic acid in guard cells of Arabidopsis (Arabidopsis thaliana) and that S1P is effective in regulating guard cell turgor. Importantly, we found that -1- similar to S1P, regulates stomatal apertures and that its action is impaired in guard cells of Arabidopsis plants harboring T-DNA null mutations in the sole prototypical G-protein alpha-subunit gene, GPA1. |

Plant J. 2007 Dec;52(6):1001-13. Epub 2007 Sep 25. On the other hand, the loss-of-function alleles of the sole Arabidopsis heterotrimeric G protein alpha subunit, GPA1, were hypersensitive to ABA in the ABA-inhibition of seed germination and early seedling development, disfavoring a genetic coupling of GCR2 by GPA1. Abscisic acid (ABA) is perceived by several different types of receptors in plant cells. |

| 19135895 | Pandey S, Nelson DC, Assmann SM: Two novel GPCR-type G proteins are abscisic acid receptors in Arabidopsis. Cell. 2009 Jan 9;136(1):136-48. We identify and characterize two novel Arabidopsis proteins that show homology to an orphan vertebrate GPCR (GPR89) and interact with the sole Arabidopsis G protein alpha subunit, GPA1, but also have intrinsic GTP-binding and GTPase activity. |

In the model plant Arabidopsis thaliana, the sole canonical G protein alpha subunit, GPA1, has been implicated in multiple signaling events, including guard cell movement regulated by the plant stress hormone abscisic acid (ABA). |

| 19513236 | Chen JG: Heterotrimeric G-protein signaling in Arabidopsis: Puzzling G-protein-coupled receptor. Plant Signal Behav. 2008 Dec;3(12):1042-5. In Arabidopsis thaliana, GCR2 has been proposed as a GPCR for the plant hormone abscisic acid. On the other hand, biochemical analysis demonstrates that the sole Arabidopsis heterotrimeric G-protein alpha subunit, GPA1, is in the activated state -bound) by default, suggesting that the heterotrimeric G-proteins may act without any GPCRs. |
