| Research Abstract |
We had found that expression of small RNAs is globally reduced during reprogramming in the moss Physcomitrella patens. We hypothesized that PpCSP proteins are involved in this process. PpCSP is presumed to function in the repression of the microRNA(miRNA) maturation. Here we found that PpCSP was localized in cytosol, and a PpCSP lesion caused attenuated reprogramming. These data suggest that PpCSP facilitates reprogramming through repressing the miRNA maturation in cytosol. To verify this hypothesis, we have performed the functional analyses of PpCSP.
