Annotation PubMed Id
Arabidopsis ABAR/CHLH specifically binds ABA (abscisic acid), and mediates ABA signalling as a positive regulator in seed germination, post-germination growth and stomatal movement, showing that ABAR/CHLH is an ABA receptor [ABAR] 17051210
ABAR/CHLH is an ABA receptor and reveal that the C-terminal half of ABAR/CHLH plays a central role in ABA signaling. 19535472
Timing of chlorophyll-AB expression protein TOC1 is induced by abscisic acid (ABA)signaling; this induction is gated by the clock and determines the timing of TOC1 binding to the ABA-related gene promoter. 19816401
ABAR spans the chloroplast envelope and that the cytosolic C terminus of ABAR interacts with a group of WRKY transcription factors that function as negative regulators of ABA signaling in seed germination and postgermination growth. 20543028
Data show that mutant subunits act as inhibitors of ChlH, and this inhibition is reversed upon addition of Gun4. 21110975
ChlH and GUN4 use distinct mechanisms to associate with chloroplast membranes. 21467578
A missense mutation of CHLH (L690 to F) is responsible for phenotype in which stomatal movements are insensitive to abscisic acid. 21562844
HSP90 proteins respond to the tetrapyrrole-mediated plastid signal to control expression of photosynthesis-associated nuclear genes 22201048
findings provide clear evidence that the Mg-chelatase-catalyzed Mg-ProtoIX production is distinct from ABA signaling, giving information to understand the mechanism by which the two cellular processes differs at the molecular level 23011401
OST1 functions downstream of ABAR in abscisic acid receptor signalling in guard cells. Consistent with this, ABAR protein is phosphorylated, but independently of the OST1 protein kinase. 26175350
