A soybean dual-specificity kinase, GmSARK, and its Arabidopsis homolog, AtSARK, regulate leaf senescence through synergistic actions of auxin and ethylene.

Mutated genes   
Mutated Gene 1 GenBank ID AY687391
Alias GmSARK
Organism Soybean (Glycine max)
Description The conceptual protein product of GmSARK contains typical domains of LRR receptor-like kinases: a cytoplasmic domain with all the 11 kinase subdomains, a transmembrane domain and an extracelullar domain containing 9 Leucine-Rich Repeat (LRR) units that may act as a receptor. The expression of GmSARK in soybean leaves was up-regulated in all the three tested senescence systems: senescing cotyledons, dark-induced primary leaf senescence and the natural leaf senescence process after florescence. Furthermore, the RNA interference (RNAi)-mediated knocking-down of GmSARK dramatically retarded soybean leaf senescence.
Mutated Gene 2 Locus name AT5G03280
Alias EIN2
Organism Arabidopsis thaliana
Description Involved in ethylene signal transduction. Acts downstream of CTR1. Positively regulates ORE1 and negatively regulates mir164A,B,C to regulate leaf senescence.
