Effect of Chitosan on the Transcriptome of the Fusarium graminearum and Hordeum vulgare L. Pathosystem

Fusarium graminearum (Fg) is a cosmopolitan fungal pathogen that causes significant losses in cereal production worldwide, both through yield reduction and grain contamination with mycotoxins. Barley (Hordeum vulgare L.) is one of the most important crop plants globally. In barley, Fg causes a disease known as Fusarium head blight (FHB). Chitosan, a natural biopolymer abundant in the environment, has proven antifungal properties and acts as a plant immunity elicitor. In our project, we sequenced the Hordeum vulgare L. (Golden Promise) and Fusarium graminearum pathosystem following chitosan treatment. The study is based on four treatments: Hv_mock (non-treated barley), Hv_CS (barley treated with chitosan), Hv_Fg (barley inoculated with F. graminearum), and Hv_Fg_CS (barley inoculated with F. graminearum and treated with chitosan). Three biological replicates were sequenced for each treatment
