| Outline of Annual Research Achievements |
We used the miRNA sequencing to identify 51 differentially expressed miRNAs and corresponding 2043 targets in the roots of Populus tomentosa colonized by Cenococcum geophilum. Then we predicted the target sequences of 51 miRNAs with psRNATarget. The prediction of miRNAs-seq and psRNATarget were further confirmed by degradome sequencing and RT-qPCR analysis. GO and KEGG enrichment analysis indicated that the target genes of some differentially expressed miRNAs regulate the ECM symbiosis through the pathways of phenylpropanoid biosynthesis, isoquinoline alkalold biosynthesis, and apoplast, etc. This work indicates that Populus miRNAs and their target genes are an important part of the regulatory network leading to ECM symbiosis development.
