Cytoplasmic RNA granules play important roles in gene expression at the post-transcriptional level. In this study, we found that the rice RNA-binding protein MEIOSIS ARRESTED AT LEPTOTENE2 (MEL2), which contributes to the control of meiotic entry timing, was a constituent of RNA granules, frequently associating with processing bodies and stress granules in the cytoplasm of premeiotic spore mother cells. MEL2 has four conserved domains and a large intrinsically disordered region, which is often responsible for formation and maintenance of granular structures. MEL2-like proteins with diverse domain structures are widely conserved in land plants and charophyte algae. In basal land plants, MEL2-like proteins are exclusively expressed in the sporophyte, which expresses meiotic genes, suggesting the functional conservation of MEL2 among land plant species. We propose here that MEL2 participates in post-transcriptional regulation of meiotic genes as a component of RNA granules to ensure proper timing of the meiotic transition.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
