Mutated genes

Locus name Alias Hormone Mutated site Paper description
AT3G54320 WRI1 abscisic acid a point mutation at intron-exon border of the first intron (G3197A)resulting in a splicing defect. encodes an APETALA2/ethylene-response element-binding protein with two AP2/EREBP DNA binding domains,WRI1 affects the regulation of sugar metabolism in the germinating seed and in the initial stage of establishment, but can be dispensed with once the seedling is established.
