TRPB — Fusarium odoratissimum str. race 4

Summary

FoTRPB (TRPB, FOC4_G10004479) in Fusarium odoratissimum str. race 4 encodes a tryptophan synthase beta subunit, confirmed by the presence of Trp_synthase_beta and Trp_synth_b_CS domains and annotated tryptophan synthase activity. The gene is associated with tryptophan formation and localises to the cytoplasm and cytosol. Expression of FoTRPB has been linked to responses to hydrogen peroxide (H2O2), Congo Red, elevated temperature (35°C), salt stress (NaCl), and the biological control agent NK51, as well as to the pathogen Fusarium oxysporum f. sp. cubense TR4. Sequence similarity places this gene within a broader family of tryptophan synthases, with related enzymes found across related genes in other species.
