RCA — Cucumis sativus

Summary

CSA_7G430770, symbol RCA (also known as CsRCA), encodes a rubisco activase on cucumber chromosome 7. The product belongs to the RuBisCO_activase_AAA_helical and RCA-like families, possesses ATP hydrolase activity, identical protein binding, and ATP binding, and is annotated with the molecular function rubisco activator. This gene is associated with light absorption, the electron transport chain, regeneration, chlorophyll fluorescence, and electron transfer. Its product localises to the thylakoid, chloroplast thylakoid membrane, chloroplast stroma, and mitochondria. RCA is linked to several agronomically important traits, including net photosynthetic rate, quantum yield, transpiration rate, stomatal resistance, plant height, and growth and development. It has also been connected to responses to low temperature, salt, low light, high temperature, and chilling stress, as well as to photosynthesis and salt tolerance phenotypes. Related genes in other species are linked to leaf senescence.
