GLUTR — Cucumis sativus

Summary

CsGLUTR (CSA_7G068600) in cucumber encodes a glutamyl-tRNA reductase with EC 1.2.1.70. The gene is associated with chlorophyll biosynthesis, heme anabolism, and porphyrin-containing compound biosynthetic processes. It has been linked to chloroplast development, de-etiolation, and photosynthetic electron transport. The encoded protein localizes to the chloroplast thylakoid membrane, envelope, and stroma. CsGLUTR is associated with leaf color and thickness, net photosynthetic rate, quantum yield, transpiration rate, stomatal resistance, plant height, root length, and arsenic concentration. It is also associated with chilling tolerance, sugar-regulated gene expression, and oxidative stress response. Related genes in other species link the glutamyl-tRNA reductase family to 5-aminolevulinic acid synthesis, heme biosynthesis, plastid signaling, and salt tolerance.
