This study shows that HDA19 and NuA4 interact to regulate stress gene activation in Arabidopsis by modulating H3K9ac and H2A.Zac, with H3K9ac being the primary driver of transcription.

The paper demonstrates that targeting H3K4me3 levels via chromatin modifiers affects crossover frequency and transcription at specific genomic loci in Arabidopsis.

COmapper uses long-read sequencing to map meiotic crossovers in Arabidopsis with high resolution, showing comparable accuracy to short-read methods and revealing crossover enrichment at gene promoters.

This study investigates the role of MutL complexes in Arabidopsis meiosis, showing that MUS81 can partially compensate for MutL{gamma} loss and that crossover interference is reduced in mlh1 mutants.

This study shows that linker histone H1 in Arabidopsis thaliana maintains rhythmic gene expression by modulating chromatin structure and transcriptional dynamics across the diurnal cycle.

The paper shows MSH2 promotes interfering crossovers and suppresses non-interfering ones at polymorphic loci in Arabidopsis, shaping crossover distribution based on genetic variation.

The paper shows that the NuA4 complex controls nuclear-encoded photosynthesis genes in Arabidopsis, with loss of key components leading to chloroplast dysfunction and reduced chlorophyll levels.

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

The paper increases meiotic recombination in Arabidopsis by combining HEI10 overexpression with RECQ4A/RECQ4B mutations, leading to more crossovers and specific recombination patterns.
