Review: Paternal imprinting in Marchantia polymorpha
Plant Science Research WeeklyHumans 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…
Chloroplast double-stranded RNA can silence nuclear genes

Slice and Dice: DCL2 Mediates the Production of 22-nt siRNAs That Influence Trait Variation in Soybean
Blog, Research, The Plant Cell, The Plant Cell: In BriefIn 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…

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…
