The paper analyzes duckweed clones to resolve taxonomic relationships and finds triploidy is common, with implications for classification and evolution.

The paper identifies pre-rRNA as a target of Dicer in quiescence and shows RiboCop silences rDNA through histone methylation.

The paper identifies bi-directionally expressed enhancers in maize with domestication signatures using integrated epigenomic and transcriptomic data from multiple tissues and inbred lines.

The paper identifies pseudouridine as a marker for germline small RNAs in plants and mammals, showing its role in epigenetic inheritance through nuclear transport.

The paper shows that retrotransposons in Arabidopsis promote centromere function through epigenetically activated small RNAs, which are essential for chromosome segregation.

The paper shows that DDM1 remodels histone H3 variants to facilitate epigenetic inheritance of DNA methylation by interacting with specific histone modifications and variants.

The paper presents the genome of the Wollemi pine, revealing ancient transposon activity and insights into its conservation and evolutionary history.

The paper identifies Brd4 as a suppressor of genome instability in Dicer1-/- mouse embryonic stem cells, showing its role in coordinating transcription and replication of satellite repeats.

Ultra-long-read sequencing resolves Arabidopsis centromeres, revealing their genetic and epigenetic structure and dynamics.

The paper identifies AGO104 as an effector of paramutation at the maize b1 locus through RdDM pathway analysis.

The paper shows that ubiquitination of Clr4SUV39H1 by Ubc4 promotes transcriptional silencing through phase separation and ncRNA regulation.

The paper compares DNA replication timing in mitotic and endocycling cells in maize roots, finding significant shifts in centromere replication timing during the endocycle.

The paper characterizes LTR retrotransposon activity in Arabidopsis using VLP DNA-seq, revealing transcriptional, post-transcriptional, and reverse transcriptional regulation by easiRNAs.

The paper describes the development of a cloud-based platform for managing, analyzing, and distributing MaizeCODE data, enhancing reproducibility and accessibility.

The paper maps meiotic DSBs in Arabidopsis using SPO11-1-oligonucleotides and shows their association with chromatin features and transposon activity.

This study shows that disrupting H3K9me2 and non-CG DNA methylation in Arabidopsis increases meiotic DSBs in centromeres and crossovers in pericentromeric heterochromatin.
