RBCS — Nicotiana attenuata

Summary

A4A49_32091 (RBCS) in coyote tobacco (Nicotiana attenuata) encodes a small subunit of ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) and belongs to the RuBisCO small subunit domain family. The gene is associated with RuBisCO activity and linked to numerous processes, including the reductive pentose-phosphate cycle, photorespiration, nonphotochemical quenching, regulation of photosynthesis, folate biosynthesis, chloroplast fission, shoot morphogenesis, and alkaloid anabolism. Associations with traits include rubisco content, photosynthetic rate, quantum yield, water use efficiency, chlorophyll content, specific leaf weight, leaf weight, stem elongation, transpiration rate, stomatal resistance, photochemical quenching, plastochron, and aphid response. Studies of related genes in other species link the family to seedling vigor, plant height, leaf angle, leaf senescence, and sugar and protein content.
