Mutated genes

Locus name Alias Hormone Mutated site Paper description
AT2G13540 ABH1 abscisic acid The T-DNA in ABH1 is inserted at the end of the 8th intron encodes the large subunit of a dimeric Arabidopsis nuclear mRNA cap-binding protein, functions in early ABA signaling.ABA-hypersensitivity.
AT4G26080 ABI1 abscisic acid G180D in the PP2C domain encodes a Calcium ion binding / protein phosphatase type 2C, Facilitates the activation of slow anion channels and stomata closure mediated by abscisic acid (ABA).
