MicroRNAs (miRNAs) are a class of conserved small RNA with a length of 21-24 nucleotides in eukaryotes, which are involved in development and defense responses against biotic and abiotic stresses. By RNA-seq, Osa-miR444b.2 was identified to be induced after () infection.

Article Synopsis
  • Recent research identifies Fol-milR1, a small RNA from the fungus Fusarium oxysporum f. sp. lycopersici, as a key player in affecting tomato plant resistance during infections.
  • The study found that knockout strains lacking Fol-milR1 showed reduced virulence on susceptible tomato plants, while overexpressing strains displayed increased virulence against resistant varieties.
  • A targeted gene, SlyFRG4, crucial for resistance, is regulated by Fol-milR1 and interacts with the host's immune response, showing how this fungal RNA can suppress tomato immunity to facilitate infection.

Due to crucial roles in gene regulation, noncoding small RNAs (sRNAs) of 20-30 nucleotides (nt) have been intensively studied in mammals and plants and are implicated in significant diseases and metabolic disorders. Elucidation of biogenesis mechanisms and functional characterization of sRNAs is often achieved using tools such as separation of small-sized RNA and deep sequencing. Although RNA interference pathways, such as quelling and meiotic silencing, have been well-described in Neurospora crassa, knowledge of sRNAs in other filamentous fungi is still limited compared to other eukaryotes.

Soluble N-ethylmaleimide-sensitive factor attachment protein receptors (SNAREs) are conserved in fungi, plants and animals. The Vam7 gene encodes a v-SNARE protein that involved in vesicle trafficking in fungi. Here, we identified and characterized the function of FolVam7, a homologue of the yeast SNARE protein Vam7p in Fusarium oxysporum f.

The vast majority of plant disease resistance () genes encode nucleotide binding site-leucine-rich repeat (NBS-LRR) proteins, which specifically determine the plant immune response and have been demonstrated to be targets of several microRNA (miRNA) families. The fungus f. sp.

Tocopherols synthesized exclusively by photosynthetic organisms are major antioxidants in biomembranes. In plants, tocopherol cyclase (TC/VTE1) catalyzes the conversion of 2,3-dimethyl-5-phytyl-1,4-benzoquinone (DMPBQ) to γ-tocopherol. In the present study, OsVTE1, which encodes a rice tocopherol cyclase ortholog, was cloned and characterized.

Receptor-like kinases (RLKs) play essential roles in plant growth, development and responses to environmental stresses. A putative RLK gene, OsSIK1, with extracellular leucine-rich repeats was cloned and characterized in rice (Oryza sativa). OsSIK1 exhibits kinase activity in the presence of Mn(2+), and the OsSIK1 kinase domain has the ability to autophosphorylate and phosphorylate myelin basic protein (MBP).
