FIB — Nicotiana attenuata

Summary

A4A49_28593 (FIB, also known as PAP3) encodes a protein with a PAP/fibrillin domain and annotated phosphoriboisomerase, starch synthase, transglycosidase and protein-binding activities. The gene is associated with the pentose-phosphate shunt, photosynthetic electron transport in photosystem II, photoprotection, ATP synthesis, and responses to jasmonic acid and light. It is linked to starch grain shape and content, anthocyanin and phenylpropanoid metabolism, chloroplast development, photosynthetic rate, shoot growth angle, and jasmonic acid content. Localisation evidence places the product in the chloroplast thylakoid membrane, thylakoid lumen, stromule, and plastoglobule. Related genes in other species are linked to photooxidative stress tolerance, anthocyanin accumulation, elaioplast development, heat stress tolerance, and carotenoid sequestration.
