GS1 — Daucus carota subsp. sativus

Summary

DcGS1 (DCAR_014698) on carrot chromosome 4 encodes a sn-glycerol 3-phosphatase with sugar-phosphatase activity, belonging to the Gpp1/Gpp2-like and HAD-superfamily hydrolase domains. The gene is associated with glycerol anabolism and localises to both mitochondria and cytosol. In carrots, DcGS1 has been linked to photosynthetic rate and nitrogen assimilation. Studies of related genes in other species connect the family to desiccation tolerance, formaldehyde stress resistance, mercury tolerance, and salt, oxidative, and osmotic stress tolerance. Sequence similarity evidence further associates the family with traits including leaf nitrogen content, root dry weight, nitrate content, chlorophyll content, seed size, and cadmium concentration.
