title: Data for: A novel and ubiquitous miRNA-involved regulatory module ensures precise phosphorylation of RNA polymerase II and proper transcription

description: Proper transcription orchestrated by RNA polymerase II (RNPII) is crucial
 for cellular development, which relies on the phosphorylation state of
 RNPII’s carboxyl-terminal domain (CTD). Sporangia, developed from mycelia,
 are essential for the destructive oomycetes Phytophthora, remarkable
 transcriptional changes are observed during the morphological transition.
 However, how these changes are rapidly triggered and their relationship
 with the versatile RNPII-CTD phosphorylation remain enigmatic. Herein, we
 found that Phytophthora capsici had undergone an elevation of
 Ser5-phosphorylation in its uncanonical heptapeptide repeats of RNPII-CTD
 during sporangia development, which subsequently changed the chromosomal
 occupation of RNPII and primarily activated transcription of certain
 genes. A cyclin-dependent kinase, PcCDK7, was highly induced and
 phosphorylated RNPII-CTD during this morphological transition.
 Mechanistically, a novel DCL1-dependent microRNA, pcamiR1, was found to be
 a feedback modulator for the precise phosphorylation of RNPII-CTD by
 complexing with PcAGO1 and regulating the accumulation of PcCDK7.
 Moreover, this study revealed that the pcamiR1-CDK7-RNPII regulatory
 module is evolutionarily conserved and the impairment of the balance
 between pcamiR1 and PcCDK7 could efficiently reduce the growth and
 virulence of P. capsici. Collectively, this study uncovers a novel and
 evolutionarily conserved mechanism of transcription regulation that could
 facilitate correct development and identifies pcamiR1 as a promising
 target for disease control.
