Basic mutant information   
Mutant name MYC5OE
Mutant/Transgenic transgene
Ecotype Col-0
Mutagenesis type transgenic
(Semi-)Dominant/Recessive dominant
Description JA-treated leaves from MYC5 overexpression transgenic plants exhibited a precocious leaf senescence phenotype, including a reduced Chl content and lower photochemical efficiency, and it enhanced the JA-regulated expression of senescence-associated genes (SAG13, SEN4, SAG113 and SAG29) and photosynthesis genes (RBCS and CAB1), suggesting that MYC5 overexpression promotes JA-induced leaf senescence.
