ACO — Pisum sativum

Summary

PsACO1 (PSAT2G152160) on garden pea chromosome 2LG1 encodes an aconitase with 4Fe-4S cluster binding, aconitase activity, and IRE binding, and is associated with the TCA cycle, citrate and isocitrate metabolism, the glyoxylate cycle, leucine biosynthesis, and nitrogen fixation. The gene is linked to seed development and germination, nodulation, cell growth, geotropism, ethylene anabolism, and response to iron ion starvation. It localises to mitochondria, cytosol, cytoplasm, apoplast, plasmalemma, plant-type vacuole, and plasmodesmata. Associations with traits include respiration rate, flower color, proline content, seed coat color, salt tolerance, and gravitropic response. Studies of related genes in other species link the family to stress response, drought tolerance, root length, and stomatal opening.
