MicroRNA-like RNAs in plant pathogenic fungus Fusarium oxysporum f. sp. niveum are involved in toxin gene expression fine tuning.

ABSTRACT: MicroRNA-like RNAs (milRNAs) are short non-coding regulatory sRNAs which play an important role in regulating gene expression at the post-transcriptional level by targeting mRNAs for degradation or inhibiting protein translation. To explore the presence of milRNAs in Fusarium oxysporum f. sp. niveum (Fon) and analyze their expression at different propagules, two categories of sRNAs were identified from Fon hyphae and microconidia using illumina sequencing. A total of 650,960 and 561,114 unique sRNAs were obtained from the hyphae and microconidia samples. With a previously constructed pipeline to search for microRNAs, 74 and 56 milRNA candidates were identified in hyphae and microconidia, respectively, based on the short hairpin structure analysis.
