Annual Reviews editions typically start with a brief autobiographical essay by a noted scientist. The 2023 edition of Annual Reviews in Plant Biology includes a profile of David Baulcombe, the well-known scientist whose work was foundational in revealing the roles of small RNAs in gene regulation and…

The May 2023 issue of The Plant Cell has a focus on RNA biology, and some of the articles for this issue are online now. I particularly enjoyed this multi-author perspective review by Manavella et al., in which 12 RNA biology groups from across the globe share the questions that they find most compelling…

Ribosomes are essential molecular machines in the cell that translate mRNA sequences into proteins. Growing parts of an organism produce many ribosomes, so that after each cell division both daughter cells have enough to translate the proteins necessary for growth and development. Defects in ribosomes…

In plants, small interfering RNAs (siRNAs) serve as key regulators of gene expression. While 24-nucleotide (nt) siRNAs are produced by DCL3 and mediate transcriptional silencing of transposons and pericentromeric chromatin through RdDM (Borges and Martienssen, 2015), 22-nt siRNAs are processed by DCL2…
