PPC1 — Glycine max

Summary

GmPPC1 (GLYMA_12G161300V4) on soybean chromosome 12 encodes a phosphoenolpyruvate carboxylase (PEPC), an enzyme with phosphoenolpyruvate carboxylase activity that also exhibits protein phosphorylated amino acid binding and protein binding. This gene is associated with a broad range of biological processes including nitrogen utilization, the urea cycle, cellular respiration, phloem sucrose loading, stomatal opening, and responses to flooding and stimulus. It has been linked to numerous agronomically important traits such as seed protein content, drought tolerance, salt tolerance, net photosynthetic rate, chlorophyll content, germination rate, root length, and seedling growth and development. The encoded protein is localized to multiple cellular compartments including the cytosol, chloroplast stroma, mitochondria, plasmalemma, and apoplast. Studies of related genes in other species link the family to phosphate starvation response, salt stress tolerance, and anaplerotic metabolism.
