HEME — Sorghum bicolor

Summary

SORBI_3003G225100, designated SbHEME on sorghum chromosome 3, encodes a uroporphyrinogen decarboxylase (EC 4.1.1.37). This gene is associated with chlorophyll anabolism, phytochrome chromophore anabolism, and response to cadmium. It has been connected to photosynthetic rate, respiration rate, protein content, and root length. The encoded protein localises to the chloroplast stroma and cytoplasm. Studies of related genes in other species link the family to grain yield, drought tolerance, chlorophyll content, leaf nitrogen content, carotene content, seed germination, days to heading, anthesis time, pollen fertility, salinity tolerance, oxidative stress response, transpiration rate, stomatal resistance, and leaf necrosis.
