Negative communication reduces G. graminis var. tritici inhibition in vitro. Strains were grown separately, mixed in appropriate ratios, and spotted as described in Materials and Methods. Bars indicate fungal growth inhibition by strain 30-84 or mixtures of strain 30-84 and either strain 30-84Z (Phz− PhzI+), strain 30-84Z/I (Phz− PhzI−), or a negative-signal strain (PU-5, PU-15, or PU-177). Treatments are indicated as follows: black bars, wild-type strain 30-84; dark grey bars, 75:25 mix of strain 30-84 and the second strain indicated; light grey bars, 50:50 mix of strain 30-84 and the second strain indicated; white bars, 25:75 mix of strain 30-84 and the second strain indicated. Strains 30-84Z, 30-84Z/I, PU-5, PU-15, and PU-177 had no fungal inhibition alone (data not shown). Error bars indicate standard errors of results for six replicates.
