ASP1 — Camelina sativa

Summary

CsASP1 (CSA17G013280) on Camelina sativa chromosome 17 encodes a cysteine-type peptidase with SUMO-specific endopeptidase activity, belonging to the peptidase C48 and papain-like cysteine peptidase superfamilies. The protein localises to the nucleus and is associated with desumoylation, sumoylation, proteolysis, and the upregulation of flowering under both short-day and long-day photoperiods. CsASP1 is associated with seed weight, plant height, seed yield, flowering time, seed size, blue light-mediated photomorphogenesis, far-red light sensitivity, nitrogen metabolism, vegetative growth, abscisic acid signaling, fertility, floral morphology, severe gametogenesis and embryo development abnormalities, disease resistance, embryo development, and female and male gametophyte development. Related genes in other species are linked to mitochondrial aspartate aminotransferase activity, abnormal floral structures and embryo development, and late flowering with decreased freezing tolerance.
