Mutated genes
Locus name	AT2G36270
Alias	ABI5/BZIP39/DPBF1/GIA1/NEM1
Organism	Arabidopsis thaliana
Description	Abscisic acid insensitive 5 (ABI5).Upregulated in senescent leaves.Encodes a member of the basic leucine zipper transcription factor family, involved in ABA signalling during seed maturation and germination.The abi5-1 mutant did exhibit a delay in senescence compared to its wild type grown on medium containing glucose in combination with low, but not in combination with high nitrogen supply.
