Mutated genes

Locus name Alias Hormone Mutated site Paper description
AT5G13530 KEG abscisic acid keg-1and keg-2 alleles have a T-DNA insert after nucleotide 1623 (from the ATG) within exon 2and afternucleotide 2368 with intron 3,respectively. kag-3 has a T-DNA insert at nucleotide 5750 with exon 11. KEG(KEEP ON GOING) contains a RING-Hca domain and a series of ankyrin (ANK) repeats.kinase domain and KEG is required for ABI5 degradation. RING-ANK( for Really Interesting New Gene-Ankyrin) family, a subgroup of RING-type E3 ligases, identified KEG

Phenotype information

Organ AttributeNo hormoneabscisic acid
Root Primary root-short
Cotyledon/Leaf othercotyledons failed to expand and remained white to very pale green compared with WT seedlings of the same age,The emergence of true leaves was greatly delayed in all three keg background, the second pair of true leaves did not emerge,and no futher growth.-
Silique/Seed otherkeg mutants displayed a strong postgermination growth arrest-
Stress otherhypersensitive to sugar and ethylene-
