PSAT2G070600 — Pisum sativum

Summary

PSAT2G070600 (GRF1) on chromosome 2LG1 encodes a 14-3-3 protein, a member of the conserved 14-3-3 family characterized by the 14-3-3 domain. The gene is associated with a wide range of molecular functions including ion transporter activity, ACP S-malonyltransferase activity, and fumarate hydratase activity, among many others. It is linked to biological processes such as non-photoreactive DNA repair, regulation of DNA replication, fumarate metabolism, and responses to cobalt ion and electrical stimulus. Associations with agronomically relevant traits include fruit yield, starch grain size, leaf chlorophyll content, plant dry weight, zinc and potassium content, seed coat hardness, and shoot system phosphorus content. The gene is also connected to phenotypes including photosynthetic capacity, carbon fixation, iron-deficiency response, and disease resistance to Pseudomonas syringae. Studies of related 14-3-3 family members in other species link the family to fungal disease resistance, virus response, metal homeostasis, and root-knot nematode susceptibility.
