Basic mutant information   
Mutant name sor1-D
Mutant/Transgenic mutant
Ecotype Col-0
Mutagenesis type T-DNA insertion_activation tag
(Semi-)Dominant/Recessive dominant
Description The suppressor1 of ore9 dominant (sor1-D) was caused by the overexpression of AtCHX24, a putative cation/H+ exchanger. The sor1-D mutation suppressed the phenotypes of ore9 in age-dependent and dark-induced senescence. Furthermore, the sor1-D mutation restored the delayed senescence phenotypes of ore1 and ore3. The sor1-D mutant also exhibited increased sensitivity to pH changes during dark-induced leaf senescence.
