ACO — Pisum sativum

Summary

PSAT6G107560 (symbol ACO, also known as PsIIL1, IIL1, PsATLEUC1, ATLEUC1) on garden pea chromosome 6LG2 encodes the large subunit of 3-isopropylmalate dehydratase, a homoaconitase/IPM dehydratase family protein with aconitase activity, 4Fe-4S cluster binding, and intramolecular hydroxytransferase activity. The gene is associated with leucine biosynthesis, the TCA cycle, glyoxylate cycle, citrate and isocitrate metabolism, oxoacid metabolism, amino acid and glucosinolate anabolism, ethylene anabolism, cell growth, geotropism, seed development and germination, and nodulation. It localizes to chloroplast stroma, plastids, mitochondria, and cytoplasm. Associations include flower color, seed coat color, proline content, salt tolerance, and plant growth. Studies of related genes in other species link the family to root length, plant growth and development, and photochemical quenching.
