Project description:Lychee (Litchi chinensis Sonn.) is a popular fruit worldwide. Lychee downy blight, caused by Peronophythora litchii (P. litchii), is one of the major diseases in lychee. In this study, we conducted a P. litchii infection experiment on the lychee leaves of GW and SFZ, and analyzed the mRNA in the treated leaves using transcriptome RNA sequencing technology. Our research will provide a preliminary basis for the prevention and control of lychee downy blight.
