ACO — Triticum aestivum

Summary

TaACO1 (TRAESCS7D02G223000) on wheat chromosome 7D encodes an aconitase, a 4Fe-4S cluster-binding enzyme with aconitase activity (EC 4.2.1.3) that also binds IRE elements. The protein localises to mitochondria and cytoplasm and is associated with tricarboxylic acid metabolism, glyoxylate metabolism, citrate metabolism, isocitrate metabolism, and ethylene anabolism. TaACO1 is associated with abiotic stress response in bread wheat, and is associated with traits including grain yield, grain weight, grain protein content, grain size, grain color, seed coat color, spike length, plant height, days to flowering, days to maturity, seed dormancy, seed germination, sprouting tolerance, osmotic adjustment capacity, proline content, transpiration rate, salinity tolerance, and drought tolerance. The gene is also linked to regulatory networks involving DREB2A, ERF48, MYB2 and other transcription factors in responses to cold and salinity. Related genes in other species are linked to salt stress tolerance.
