AAD1 — Solanum tuberosum

Summary

PGSC0003DMG400016247, designated StAAD1 on potato chromosome 11, encodes a stearoyl-CoA 9-desaturase and stearoyl-[ACP] desaturase with a fatty acid desaturase-2 domain, localizing to the plastid, chloroplast stroma and thylakoid. The gene is associated with fatty acid homeostasis, unsaturated fatty acid and jasmonic acid anabolism, oxylipin metabolism, lipogenesis, and regulation of salicylic acid- and jasmonic acid-mediated signaling pathways. It has been linked to defense responses to insects, cold acclimation, endosperm development, and sucrose metabolism. Associations include linoleic acid, sugar, and protein content, respiration rate, germination rate, and traits such as dwarfism, altered fatty acid composition, disease resistance, spontaneous cell death, seed oil content, and cuticle development. Studies of related genes in other species link the family to seed yield, embryo development, and aphid resistance.
