Great collaboration with Andreas Houben @YiTzuKuo and @MacasLab now published online in @NatureComms. Here we show that holocentromeres can also consist of only a few centromeric units with megabase-sized repeat arrays in similar ranges as in monocentromeres! Crazy!

A new type of plant holocentromere ! Excited to be part of a great team led by Houben lab at @LeibnizIPK, including @YiTzuKuo, @marques_et_al and many others. Supported by #GACR, @BiologyCentre and @ELIXIRCZ. doi.org/10.1038/s41467-023-3…

The giant diploid faba genome unlocks variation in a global protein crop

Increasing the proportion of locally produced plant protein in currently meat-rich diets could substantially reduce greenhouse gas emission and loss of biodiversity. However, plant protein production...

The ecology of palm genomes: repeat‐associated genome size expansion is constrained by aridity

Genome size varies 2400-fold across plants, influencing their evolution through changes in cell size and cell division rates which impact plants' environmental stress tolerance. Repetitive element...

Very happy to see this Preview on @CellCellPress written by Paul Talbert & Steven Henikoff about our recent paper on how repeat-based holocentromeres influence the (epi) genome architecture!!! Holocentromeres rock 🎸🕺🎶🤟 cell.com/cell/fulltext/S0092…

Centromeres organize (epi)genome architecture

In some plants and animals, microtubules attach across the length of the chromosome in mitosis, forming a holocentromere instead of a single centromeric locus. A new study in Cell shows that in the...

Hi @MendeleySupport I was wondering, is there a citation plugin for #LibreOffice available for the new Mendeley Reference Manager? Very nice there is a Linux app! But this wouldn’t be much use if I can’t insert citations…

⚠️NEW PREPRINT⚠️ Repetitive DNA explains most of plants' 2400x genome size variation, influencing plant niches. Genomic repeat ‘communities’ parallel ecological communities, but we don’t know what influences their composition. We adress this using palms🌴bit.ly/3ombS0G
