How to make an extraordinary machine: SMALL ORGAN 4 regulates ribosome biogenesis in plants

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…

Expanded function of the P-type pentatricopeptide repeat protein ATP4 in RNA editing

Tianhu Sun ORCID ID: 0000-0002-2513-1387 Plant Breeding and Genetics Section, School of Integrative Plant Science, Cornell University, Ithaca, New York 14853 ts753@cornell.edu  Chloroplasts are semi-autonomous organelles that retain their own genomes derived from their cyanobacterial ancestors,…

Slice and Dice: DCL2 Mediates the Production of 22-nt siRNAs That Influence Trait Variation in Soybean

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…

Excising the mystery of single guide RNA processing

Sophia G. Zebell Howard Hughes Medical Institute, Cold Spring Harbor Laboratory, Cold Spring Harbor, NY, USA zebell@cshl.edu Over the past 10 years, utilization of CRISPR-Cas9 genome editing in plants has rapidly and significantly altered the scale and scope of both basic research and crop development.…

Callose deposition during pollen development

Madeleine Seale University of Oxford maddy.seale@plants.ox.ac.uk Callose is a cell wall component that is dynamically deposited and degraded during pollen development. Thanks to a new paper investigating pollen formation in cotton (Gossypium hirsutum), we now know that a pollen-specific protein…
