LSU — Nicotiana attenuata

Summary

A4A49_34492 (LSU, GGPS) in Nicotiana attenuata encodes a prenyl diphosphate synthase with all-trans-nonaprenyl-diphosphate synthase (geranyl-diphosphate specific) activity, FGPP synthase activity, geranyltranstransferase activity, dimethylallyltransferase activity, prenyltransferase activity, farnesyltranstransferase activity, transferase activity, and metal binding. The gene is associated with geranylgeranyl diphosphate anabolism, geranyl diphosphate anabolism, farnesyl diphosphate anabolism, plastoquinone anabolism, isoprenoid metabolism, ubiquinone anabolism, the MEP pathway, response to herbivore, pigmentation, isoprenoid anabolism, carotenoid anabolism, protein synthesis, response to insect, terpenoid anabolism, blue light response, response to salicylate, response to jasmonic acid, and low light tolerance. It is linked to the polyprenyl diphosphate synthase complex, etioplast, chloroplast thylakoid membrane, chloroplast stroma, ER, plastid, and mitochondria. Associations with protein content, photosynthetic rate, chlorophyll content, and drought tolerance have been noted. Related genes in other species link the family to carotenoid biosynthesis and sesterterpene production.
