The phytopathogen Glomerella cingulata (anamorph: Colletotrichum gloeosporioides ) infects host tissue by means of a specialised infection structure, the appressorium. The Saccharomyces cerevisiae α‐mating factor pheromone, the Saccharomyces kluyveri α‐mating factor pheromone and a hendecapeptide produced by G. cingulata inhibit appressorium development. The amino acid sequence of the G. cingulata peptide, GYFSYPHGNLF, is different from that of the mature pheromone peptides of other filamentous fungi. The peptide has sequence similarity with the Saccharomyces α‐mating factor pheromones, but is unable to elicit growth arrest in S. cerevisiae .
