RCA1 — Zea mays

Summary

ZM00001EB164390 (RCA1) on maize chromosome 4 encodes a rubisco activase, an ATP hydrolase with lyase activity that binds ATP and identical proteins. The product localises to the thylakoid and chloroplast stroma and is associated with C4 photosynthesis, NADP-malic enzyme C4 photosynthesis, RuBisCO assembly, malate metabolism, stomatal opening, response to radiation, water and flooding, pigmentation, programmed cell death, phosphorus utilization, nitrogen compound transport, polyamine anabolism, sulfur metabolism, memory, and metabolic burst. The gene is linked to numerous agronomic traits including grain yield, grain weight, net photosynthetic rate, quantum yield, chlorophyll content, plant height, flag leaf area, tiller number, panicle number, root length, shoot dry weight, leaf number, anthesis time, canopy and leaf temperature, transpiration rate, stomatal resistance, water use efficiency, rubisco content, sucrose, starch and protein content, proline content, heterosis, heat tolerance, and salinity tolerance.
