EIL1 — Sorghum bicolor

Summary

SORBI_3001G387600, designated SbEIL1 on sorghum chromosome 1, encodes an EIN3-like DNA-binding domain protein with sequence-specific DNA binding, transcription coactivator activity, and histone deacetylase activity, and also binds chromatin, histones, and kinases. SbEIL1 is associated with the regulation of ethylene-mediated signaling, the jasmonic acid/ethylene-dependent systemic resistance pathway, and responses to wounding, defense against insects, iron transport, ascorbate biosynthesis, secondary cell wall biogenesis, nitrogen utilization, and sulfate starvation. It localizes to the nucleus, cytoplasm, chloroplast envelope, and SCF and Sin3-type complexes. The gene has been linked to traits including shoot elongation under submergence, iron sensitivity, seed protein content, plant size, seed set, lignin biosynthesis, aphid response, photoperiod-sensitive flowering, male sterility, and root and leaf development. Related genes in other species connect the family to ethylene response, root elongation, salt stress tolerance, and chlorophyll degradation.
