Mutated genes   
Locus name AT4G30520
Alias AtSARK
Organism Arabidopsis thaliana
Description Inducible over-expression of AtSARK caused precocious senescence and abnormal floral organ development nearly identical to the GmSARK over-expressing plants; whereas a T-DNA insertion mutant of AtSARK showed significantly delayed senescence.
