The majority of woody plants are able to form ectomycorrhizal (ECM) symbioses with fungi.
During symbiotic development, plants undergo a complex re-programming process
involving a series of physiological and morphological changes. MicroRNAs (miRNAs) are
important components of the regulatory network underlying symbiotic development. To
elucidate the mechanisms of miRNAs and miRNA-mediated mRNA cleavage during
symbiotic development, we conducted high-throughput sequencing of small RNAs and …

抄録 MicroRNAs (miRNAs) are important components of the regulatory network of
ectomycorrhizal (ECM) symbiosis. To unravel the mechanisms of miRNAs and miRNA-
mediated mRNA cleavage during ECM symbiosis, we carried out the high-throughput
sequencing of small RNAs and degradome tags of symbiont of Populus tomentosa roots and
Cenococcum geophilum. This led to the annotation of 51 differentially expressed miRNAs of
P. tomentosa, including 13 novel miRNAs. An increased or decreased accumulation of …
