GGR — Nicotiana attenuata

Summary

A4A49_09152 (GGR) on chromosome 7 of coyote tobacco (Nicotiana attenuata) encodes a protein with polyprenyl synthetase domains and multiple annotated enzyme activities, including all-trans-nonaprenyl-diphosphate synthase (geranyl-diphosphate specific) activity, FGPP synthase activity, geranyltranstransferase activity, dimethylallyltransferase activity, prenyltransferase activity, farnesyltranstransferase activity, and transferase activity, as well as GPCR activity, transmembrane signaling receptor activity, protein translocase activity, GTPase activity, GTP binding, metal binding, and identical protein binding. The gene is associated with geranylgeranyl diphosphate, geranyl diphosphate, farnesyl diphosphate, and carotenoid anabolism, as well as the MEP pathway, monoterpene biosynthesis, isoprenoid metabolism, and plastoquinone anabolism. It is linked to response to herbivore and insect, chloroplast localization, and protein targeting. Associations include rubisco and chlorophyll content, photosynthetic rate, leaf chlorosis, root thickness, and short roots. The gene is connected to chloroplast development, biogenesis, protein import, photosynthesis, seedling lethality, cold stress response, lipid metabolism, and fatty acid composition. Related genes in other species link the family to plastid lipid accumulation and oleic acid content.
