RBCS — Hordeum vulgare subsp. vulgare
Summary
HORVU.MOREX.R3.5HG0469020 (HvRBCS) on barley chromosome 5H encodes a RuBisCO small subunit, a component of the Calvin cycle enzyme. The gene is associated with RuBisCO assembly, photorespiration, and carbohydrate metabolism. It has been linked to photosynthetic rate, CO₂ assimilation, and chloroplast development and function. Associations also include responses to thermal, oxidative, and salinity stress, as well as grain filling, flowering time, and meristem and root development traits. The product localises to the thylakoid and chloroplast envelope. Related genes in other species are linked to photosynthetic capacity, photoinhibition, and temperature stress tolerance.
