Functional analysis of the tobacco mosaic virus tRNA-like structure in cytoplasmic gene regulation.

abstract：:The mitochondrial DNA of Neurospora crassa has a heterogeneous intramolecular base distribution. A contiguous piece, representing at least 30% of the total genome, has a G+C content that is 6% lower than the overall G+C content of the DNA. The genes for both ribosomal RNAs are contained in the remaining, relatively G+...

abstract：:Small RNA (sRNA)-mediated gene silencing phenomena, exemplified by RNA interference (RNAi), require a unique class of proteins called Argonautes (AGOs). An AGO protein typically forms a protein-sRNA complex that contributes to gene silencing using the loaded sRNA as a specificity determinant. Here, we show that MoAGO2...
