TMEM37 and infection: We found a significant increase in the gene expressions of PR-1 and PR-2 in 1 and 2 dpi in R. alboglabra compared with the gene expression in B. napus. Such increases in gene expression occurred to counteract biotrophic pathogen, thereby suggesting that RRCC quickly responds to infection by developing resistance to E. cruciferarum, and resistance continues to increase at 2–4 dpi.
