Comparative transcriptome profiling and co-expression network analysis uncover the key genes associated with pear petal defense responses against infection.

Pear brown rot and blossom blight caused by seriously affect pear production worldwide. Here, we compared the transcriptomic profiles of petals after inoculation with using two pear cultivars with different levels of sensitivity to disease (Sissy, a relatively tolerant cultivar, and Kristalli, a highly susceptible cultivar). Physiological indexes were also monitored in the petals of both cultivars at 2 h and 48 h after infection (2 HAI and 48 HAI).

Global Transcriptome Analysis of the Peach () in the Interaction System of Fruit-Chitosan-.

The peach ( L.) is one of the most important stone-fruit crops worldwide. Nevertheless, successful peach fruit production is seriously reduced by losses due to the causal agent of brown rot.
