EIL1 — Cucumis sativus

Summary

CSA_1G601520 (EIL1, also known as CsEIL1 or CsEIN3) on cucumber chromosome 1 encodes an EIN3-like protein containing an EIN3_N domain and an ethylene-insensitive-like DNA-binding domain. The product exhibits sequence-specific DNA binding, transcription factor activity, and binds to histones, chromatin, and kinases. In cucumber, EIL1 is associated with sex differentiation, flower formation, regulation of defense responses to insects and wounding, ethylene-mediated signaling, iron transport and response, ascorbate biosynthesis, and desiccation response. It localizes to the nucleus, cytoplasm, and chloroplast envelope. The gene is linked to traits including iron sensitivity, shoot elongation under submergence, branch angle, seed protein content, stamen morphology, aphid response, photosynthetic rate, and high temperature stress response. Studies of Arabidopsis relatives connect the EIN3/EIL family to ethylene sensitivity, iron efficiency, flowering time, and resistance to fungal pathogens and herbivory.
