High impact information on EIN4

Here, we identified two Arabidopsis genes, EIN4 and ERS2, by cross-hybridizing them with ETR2 [1].
EIN4 previously was isolated as a dominant ethylene-insensitive mutant [1].
Four of these loci, designated ein4, ein5, ein6 and ein7, are insensitive to ethylene [2].
Trichoblast cell length was reduced by low phosphorus availability in all genotypes, but even more so for ein2-1 and ein4 [3].

Biological context of EIN4

With the exception of ein4, the degree of inhibition of hypocotyl elongation was correlated with the strength of the ethylene-insensitive phenotype based on the triple response assay [4].

Associations of EIN4 with chemical compounds

However, loss-of-function mutations in ETR1, ETR2, and EIN4 significantly prolonged the time for recovery of growth rate after ethylene was removed [5].
