Transcriptional analysis of genes encoding CAZymes and related CBMs in M. larici-populina and P. graminis during urediniospore germination and infection.
Expression cluster analysis of genes encoding PCW- (a) and FCW- (b) degradation-associated CAZymes and respective related CBMs in M. larici-populina and expression cluster analysis of genes encoding PCW- (c) and FCW- (d) degradation-associated CAZymes and respective related CBMs in P. graminis were performed based on the expression average values of three independently repeated tests27,28. Red and green indicate high expression and low expression respectively. For each heat map: top, stage tree; left, gene tree. Expression values are indicated in log2 scale. Column diagrams show the proportions of differentially expressed genes encoding PCW- (e) and FCW- (f) degradation-associated CAZymes and respective related CBMs, during M. larici-populina urediniospore germination and different infection stages on poplar leaves, compared with dried-urediniospores in vitro. Column diagrams show the proportions of differentially expressed genes encoding PCW- (g) and FCW- (h) degradation-associated CAZymes and respective related CBMs during P. graminis urediniospore germination and infection on wheat and barley, respectively, compared with urediniospores in vitro. The differentially expressed genes in the microarray data were identified with the threshold of |Fold change |  2 and an adjusted p-value < 0.05. Up, Down and Un indicate the up-regulated, down-regulated and unchanged expressed genes, respectively.
