D14 — Pisum sativum

Summary

PSAT6G018360 (symbol D14, also known as RMS3) on garden pea chromosome 6LG2 encodes a protein with an alpha/beta hydrolase fold and esterase activity. This gene is associated with strigolactone signaling and response, including cellular response to strigolactone, strigolactone-mediated axillary bud dormancy, and secondary shoot formation. It has been linked to lateral growth, circumnutation, exploration behavior, regeneration, and arbuscular mycorrhizae formation. The encoded protein localises to the cytoplasm and nucleus and is linked to auxin transport and anabolism, endocytosis, and hormone signaling pathways. Associations with agronomically relevant traits include shoot branching, flowering time, drought resistance and tolerance, heat tolerance, osmotic stress tolerance, nitrogen deficiency response, seed germination, leaf senescence, stomatal closure, and cell membrane integrity. Studies of related genes in other species link the family to plant branching, lateral root density, and sepal senescence.
