General information

Mutant name eer1
Mutant/Transgenic plant mutant
Ecotype Ws
Mutagenesis type T-DNA insertion_knock out
Dominant/Recessive/Semi-dominant
PMID 11161061
CommentFollowing ethylene treatment, the dark-grown eer1 hypocotyl response is greatly exaggerated in comparison with the wild type, indicating that the eer1 phenotype is not simply due to ethylene overproduction. eer1 seedlings have significantly elevated levels of basic-chitinase expression, suggesting that eer1 may be highly sensitive to low levels of endogenous ethylene.
