Basic mutant information   
Mutant name mybh-1
Mutant/Transgenic mutant
Ecotype Col-0
Mutagenesis type T-DNA
(Semi-)Dominant/Recessive recessive
Description Plants constitutively overexpressing MYBH underwent premature leaf senescence and showed enhanced expression of leaf senescence marker genes. In contrast, the MYBH mutant line, mybh-1, exhibited a delayed-senescence phenotype.
