PSAT7G082120 — Pisum sativum

Summary

PSAT7G082120 (CRY) on garden pea chromosome 7LG7 encodes a DELLA protein belonging to the GRAS transcription factor family, with domains including DELLA_N_sf and TF_GRAS. The product exhibits gibberellin binding, E-box binding, phytochrome binding, and far-red light photoreceptor activity, among numerous molecular functions. CRY is associated with regulation of gibberellic acid-mediated signalling, desumoylation, fruit septum development, inflorescence meristem growth, trichome spacing, and specification of plant organ axis polarity. It localises to the SCF complex, nuclear body, plastid, and plasmodesma. The gene is linked to traits including specific leaf area, flower number, seed coat hardness, linoleic and linolenic acid content, fruit quality and ripening, leaf elongation rate, plant dry weight, and copper sensitivity. Studies of related genes in other species connect the DELLA family to drought tolerance, fruit ripening, seed number, and shoot apical meristem maintenance.
