Expression Profiles of 14 Predicted Genes Differentially Expressed in the Comparison of Mla-Specified Rar1-Dependent (Mla6 and Mla13) and -Independent (Mla1) Incompatible Interactions.
(A) Average signal intensities for each time point in the Mla1-, Mla6-, and Mla13-specified interactions were used in the cluster analysis. A data matrix of signal intensities in genotype-isolate combinations involved in the comparisons was loaded in GeneSpring 5.1 software. Similarities of expression profiles were calculated using a Pearson correlation and presented in a dendrogram using the hierarchal clustering algorithm. Cells lower than the reference (median) are designated in green, and cells higher than the reference (median) are shown in magenta.
(B) Reciprocal expression profiles of selected genes in the different combinations of Rar1-dependent and -independent comparisons. Estimated mean natural log signal intensities are plotted for each isolate and time point along with their standard errors.
