Peptide inhibitors of appressorium development in Glomerella cingulata.
The phytopathogen Glomerella cingulata (anamorph: Colletotrichum gloeosporioides) infects host tissue by means of a specialised infection structure, the appressorium. The Saccharomyces cerevisiae alpha-mating factor pheromone, the Saccharomyces kluyveri alpha-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 alpha-mating factor pheromones, but is unable to elicit growth arrest in S. cerevisiae.
