| Outline of Final Research Achievements |
RNA granules, which composed of various RNAs and proteins, are cytoplasmic granules to participate in post-transcriptional regulations including mRNA transport, translation repression, RNA degradation, small RNA functions and so on. We focused on representative RNA granules, stress granules and P-bodies, and investigated the morphologies of RNA granules by electron microscopy. Our analyses revealed that RNA granules are about from 100 to 300 nm in diameter and have a filamentous pattern in granules. In addition, we also found that ribosomes are not observed in RNA granules. Our research figured out the morphology of RNA granules in plant cells and provided a base for future plant RNA granules researches.
