We report a histone variant, H2B.8, mediates sperm chromatin and nuclear condensation in Arabidopsis thaliana. We propose that H2B.8 is an evolutionary innovation of flowering plants that achieves nuclear condensation compatible with active transcription.
We report here that gentic methylation in the male germline, from meiocytes to sperm, is established by siRNAs transcribed from transposons with imperfect sequence homology.
We revealed extensive N4 cytosine methylation (4mC) in a eukaryote (Marchantia), identifies novel DNA methyltransferases, and demonstrates the biological function of 4mC during sexual development.
We discovered specific
We characterised the extent of TE expression in Arabidopsis pollen vegetative cells, and determined that their expression relies on loss of histone H1 in concert with the DEMETER demethylase.
In two back-to-back collaborative papers, we showed that germline cells have more robust DNA methylation in Arabidopsis and rice genomes, and that rice...
