Mutated genes

Locus name Alias Hormone Mutated site Paper description
AT1G08260 ABO4 abscisic acid Similar to POL2A, DNA polymerase epsilon catalytic subunit. Essential for Arabidopsis growth. Null homozygotes are embryo lethal, partial loss of function alleles show embryo patterning defects such as root pole displacement. Delayed progression through cell cycle results in embryos with smaller numbers of larger cells.
AT4G26080 ABI1 abscisic acid 4171G->A encodes a Calcium ion binding / protein phosphatase type 2C, Facilitates the activation of slow anion channels and stomata closure mediated by abscisic acid (ABA).
