The transcript expression of SsWRKY22 and SsWRKY33, TF-encoding core genes with two and three alleles, respectively, decreased sharply in response to infection with X. albilineans, suggesting that the decreased expression of these genes could be an important aspect of the sugarcane response to X. albilineans (Fig. 5a; Fig. 6b). Here, TF is linked to infection.
