Basic mutant information
Mutant name	ors1-1/anac092-1
Mutant/Transgenic	mutant
Ecotype	Col-0
Mutagenesis type	T-DNA insertion_knock out
(Semi-)Dominant/Recessive	recessive
Description	ors1-1/anac092-1 double mutant has a delayed senescence phenotype. However, homozygous ors1-1/anac092-1 double mutant but obtained no evidence for a significant further delay in leaf senescence compared to the single-gene mutants.

Mutated genes
Mutated Gene 1 Locus name AT3G29035 Alias ANAC059/ATNAC3/ORS1 Organism Arabidopsis thaliana Description no apical meristem (NAM) family protein
Mutated Gene 2 Locus name AT5G39610 Alias ORE1/AtNAC092/AtNAC2/AtNAC06 Organism Arabidopsis thaliana Description ORE1 expression is up-regulated concurrently with leaf aging by EIN2 but is negatively regulated by miR164. miR164 expression gradually decreases with aging through negative regulation by EIN2, which leads to the elaborate up-regulation of ORE1 expression.
