VP1 — Camelina sativa

Summary

CsABI3 (also known as VP1, SIS10, or CsSIS10) on Camelina sativa chromosome 15 encodes a B3 DNA-binding domain protein of the LEC2-like family, with annotated molecular functions including sequence-specific DNA binding, transcription coactivator activity, and phytochrome binding. This gene is associated with positive regulation of seed maturation, cellular response to gibberellin stimulus, regulation of triglyceride catabolic process, and response to trehalose. It is linked to numerous agronomic traits including seedling vigor, seed set percent, linoleic and linolenic acid content, vegetative vigor, water stress response, photoperiod sensitivity, and cadmium concentration. Additional associations include plant male sterility, anther and stamen morphology, petal length and morphology, leaf trichome density, and aluminum response. Studies of related genes in other species link the family to seed development, abscisic acid responsiveness, desiccation tolerance, seed longevity, oil accumulation, and seed degreening.
