FIB — Nicotiana attenuata
Summary
A4A49_42345 (FIB, LIPC) in coyote tobacco encodes a PAP/fibrillin domain-containing protein with phosphoriboisomerase, starch synthase, transglycosidase and protein-binding activities. It is associated with the pentose-phosphate shunt, photosynthetic electron transport in photosystem II, photoprotection, ATP synthesis, and responses to jasmonic acid and light. The protein localises to the chloroplast thylakoid membrane, stroma, envelope and stromules. FIB is linked to starch grain shape and content, anthocyanin content, shoot growth angle, root morphology, photosynthetic rate, chloroplast development, leaf senescence, high-light stress tolerance, plastoglobule formation, and jasmonate biosynthesis. Related genes in other species link the family to photooxidative stress tolerance, anthocyanin accumulation, elaioplast development, heat stress tolerance, and carotenoid sequestration.
