Tag: Gene Silencing

Humans and flowering plants spend most of their lives in a diploid state with two copies of each chromosome in most cells, but to reproduce they produce haploid gametes through meiosis. By contrast, bryophytes (liverworts, hornworts, and mosses), spend most of their lives in the haploid state. They produce…

Bélanger et al. investigate the silencing of nuclear genes mediated by chloroplast double-stranded RNA transgenes The Plant Cell (2023). https://doi.org/10.1093/plcell/koad165 By Sébastien Bélanger Background: Plants have three genomes: the nuclear, the mitochondrial and the chloroplast…

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…

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…
