GLRA3 and infection: At 24 HPI, 488 DEGs were enriched in GO terms such as ligand-gated ion channel activity, cellular response to hypoxia, oxidoreductase activity, systemic acquired resistance, and positive regulation of defence response (Additional file: Figure S4B), which reveals that DR has made a series of responses to infection stress, such as the production of peroxidase and activation of the systemic acquired resistance process and defence response, illustrating that DR can arrange the defence system more quickly and effectively to resist MP.
