So far, only a few sRNAs, such as Bc‐siRNAs from B. cinerea (Weiberg et al., 2013; M. Wang et al., 2017), Pst‐milR1 from P. striiformis (B. Wang et al., 2017), and ccm‐miRNAs from C. campestris (Shahid et al., 2018), were reported to be exported from pathogens or parasitic plants to host plants during infection. This evidence concerns the gene MILR1 and infection.
