AP2 — Lactuca sativa

Summary

LsAP2, encoded by gene LSAT_V11C600310710 on lettuce chromosome 6, is a DNA-binding transcription factor containing an AP2/ERF domain. It is associated with blue light photoreceptor activity, transcription corepressor and coactivator activities, and protein homodimerization. The gene is linked to the regulation of floral organ abscission, seed development, endosperm development, seed coat development, and starch biosynthesis. It has been connected to plant epidermal cell fate specification, organ morphogenesis, and the negative regulation of cellulose anabolism. Associations with traits include seed color, seed set, flowering time, plant size, branch angle, trichome morphology, and responses to light, aphids, and jasmonic acid. Related genes in other species link the family to trichome development, mucilage production, tannin accumulation, and drought tolerance.
