Basic mutant information   
Mutant name upl5-2
Mutant/Transgenic mutant
Ecotype Col-0
Mutagenesis type T-DNA insertion_knock out
(Semi-)Dominant/Recessive recessive
Description Two T-DNA insertion lines (upl5-1 and upl5-2) showed the same senescence phenotype as WRKY53 over-expressers. Over-expression of WRKY53 in the upl5 background enhanced the accelerated senescence phenotype of WRKY53 over-expressers.
