Basic mutant information   
Mutant name sles
Mutant/Transgenic mutant
Ecotype Rice (Oryza sativa)
Mutagenesis type T-DNA
(Semi-)Dominant/Recessive recessive
Description a spotted leaf sheath (sles).The sles mutant displayed early senescence, as shown, by color loss in the mesophyll cells, a decrease in chlorophyll content, and upregulation of chlorophyll degradation-related and senescence-associated genes. ROS content was also elevated, corresponding to increased expression of genes encoding ROS-generating enzymes.
