GL2 — Cucumis sativus

Summary

CsGL2 (CSA_7G447000) on cucumber chromosome 7 encodes a homeodomain-leucine zipper (HD-Zip IV) transcription factor with a START domain and lipid-binding activity, localised to the nucleus. It is associated with plant epidermal cell fate specification, trichome differentiation and branching, and downregulation of trichoblast fate. The gene has been linked to numerous traits including trichome morphology, root epidermal cell length, lateral root length, stem elongation, leaf elongation rate, male flowering, pollen fertility, and seed coat morphology. Phenotypic associations include trichome development and spacing, root hair density and growth, epidermal cell-type differentiation, seed coat mucilage synthesis and development, seed oil content, anthocyanin and fatty acid biosynthesis, stomatal development, osmotic stress response, and arsenic accumulation and tolerance.
