PR1 — Fusarium odoratissimum str. race 4

Summary

FOC4_G10005135 (PR1) in Fusarium odoratissimum str. race 4 encodes a serine-type endopeptidase of the peptidase S8 subtilisin-like family, with metal-binding capacity and predicted extracellular localisation, and is associated with proteolysis. The gene is linked to the fungal pathogen Fusarium oxysporum f. sp. cubense TR4 and has been connected to differential expression under Congo Red, temperature (15°C, 35°C), and NaCl stress conditions. It shares related sequences with AsES, ALP, and ALP1. Studies of related genes in other species link subtilisin-like proteases to apoplastic and cytoplasmic effector functions, though pathogenicity was unaffected in some relatives. The family has also been associated with traits such as drought tolerance, chlorophyll content, root length, and germination rate in plants, as well as with fusarium ear blight.
