Fig. 2: Differential transcription of R. irregularis genes in the roots of host genotype COL2215 that are known to be involved in different stages of mating responses in other fungi.

The graphs show normalized counts of transcripts that displayed significantly higher gene transcription in the coinoculation treatment (with isolates B1 and DAOM197198 together) compared with the two single-inoculation treatments (B1 or DAOM197198). The number of genes reflects the genes that were found in common between (1) isolate DAOM197198 vs. coinoculation and (2) isolate B1 vs. coinoculation.
