FMO1 (TRAESCS4A02G006600) — triticum aestivum

Summary

TRAESCS4A02G006600, designated FMO1 and also known as YUCCA4, on bread wheat chromosome 4A, encodes a flavin-containing monooxygenase with indole-3-pyruvate monooxygenase activity, NADP and FAD binding, and N,N-dimethylaniline monooxygenase activity. The gene is associated with auxin anabolism and anther dehiscence. Observed in wheat, FMO1 is linked to powdery mildew resistance, and associations extend to stripe rust, grain yield, spikelet length, spike length, anther length, germination rate, drought tolerance, and salt tolerance. The gene is associated with salicylic and jasmonic acid signaling, regulation of seed germination and coleoptile growth under submergence, and expression of transcription factors including WRKY45, NAC77, and MYB80. Related genes in other species link the family to auxin biosynthesis via the indole-3-pyruvate pathway.
