Some studies have found that the deletion or mutation of the mu1a gene of Magnaporthe (M. oryzae U1A, MU1A) may lead to abnormal splicing of the precursor mRNA, affecting the normal expression of some proteins, normal growth and metabolism processes, and ultimately, the pathogenicity of Magnaporthe. In the defence response to fungal infection, AS may be as important as traditional transcriptional control in C. sublineola-inoculated sorghum seedlings, as reported in a study based on next-generation sequencing technologies [40]. Here, AP1M1 is linked to fungal infectious disease.
