GluTR — Arabidopsis thaliana
Summary
AT1G58290, also known as HEMA1 or GluTR, encodes glutamyl-tRNA reductase (EC 1.2.1.70). The encoded protein localises to the chloroplast membrane, thylakoid, envelope and stroma. HEMA1 is associated with chlorophyll a and heme A biosynthesis, tetrapyrrole metabolism, and the regulation of tetrapyrrole anabolism, including its inhibition and downregulation of chlorophyll synthesis. The gene is linked to plastid signalling, salt tolerance, and chilling tolerance. Associations with photosynthetic traits include net photosynthetic rate, transpiration rate, photochemical quenching, and stomatal resistance. HEMA1 is also connected to chloroplast development, shoot development, plant growth and survival, and responses to light and sugar. Related genes in other species link the family to porphyrin synthesis, oxidative stress response, and sugar-regulated gene expression.
