ATXR5 and ATXR6 restrict meiotic crossover formation within heterochromatin in Arabidopsis

Journal of Integrative Plant Biology, EarlyView.
The Arabidopsis H3K27 mono‐methyltransferases ATXR5 and ATXR6 repress crossovers within meiotic heterochromatin, are required for heterochromatin condensation and H3K27me1 establishment, and specifically influence the maintenance of DNA methylation in meiocytes.

DNMT3B PWWP mutations cause hypermethylation of heterochromatin [PDF]

The correct establishment of DNA methylation patterns is vital for mammalian development and is achieved by the de novo DNA methyltransferases DNMT3A and DNMT3B. DNMT3B localises to H3K36me3 at actively transcribing gene bodies via its PWWP domain.

SlBPC1 regulates fruit elongation by directly repressing SlOFP2/SlOFP21 and SUN expression in tomato

Journal of Integrative Plant Biology, EarlyView.
In tomato, switching off the transcription factor gene SlBPC1 leads to longer fruits by altering cell division patterns during early fruit development. The SlBPC1 regulatory pathway includes the SlOFP2, SlOFP21, and SUN genes, offering valuable targets for breeding tomatoes with market‐preferred shapes.

Chromosome Banding and Heterochromatin in Vicia Faba

, 1977
This study documents the distribution of bands in Vicia faba root-tip chromosomes as shown by acid treatment, quinacrine mustard fluorescence, various forms of Giemsa banding and orcein banding methods, and demonstrates the coincidence of these bands ...

20th Anniversary of human‐induced pluripotent stem cells and the role of microscopy

Journal of Microscopy, EarlyView.
Abstract It has been 20 years since the pioneering work of Shinya Yamanaka and Kazutoshi Takahashi at Kyoto University led to the first successful generation of induced pluripotent stem cells (iPSCs) from mouse embryonic and adult fibroblast cells. iPSCs have the capacity to differentiate into any type of cell in the human body, and as such, they have ...

'Arc' escorts siRNAs in heterochromatin assembly

, 2007
RNA interference (RNAi) is important in directing heterochromatin assembly at centromeres in fission yeast, which is crucial for maintaining a stable genome through mitotic and meiotic divisions. In this issue, Buker et al. describe a new Argonaute siRNA

Molecular Links Between Heat Stress and DNA Damage Response in Plants

Plant, Cell &Environment, EarlyView.
ABSTRACT Climate change poses a major threat to agricultural productivity and, consequently, to global food security. Among the consequences of climate change, heat stress (HS) has emerged as a critical factor limiting crop performance. This has stimulated extensive research over the past decade to elucidate the molecular and physiological mechanisms ...

Combined Abiotic Stress Rewires DNA Methylation to Modulate Regulatory Potential Rather Than Transcription in Arabidopsis

Plant, Cell &Environment, EarlyView.
ABSTRACT Plants are simultaneously exposed to multiple abiotic stresses, yet how opposing epigenetic signals are integrated remains unclear. Here, we investigated the combined effects of heat stress and phosphate deficiency in Arabidopsis thaliana, two conditions with antagonistic impacts on DNA methylation.

Confining euchromatin/heterochromatin territory: jumonji crosses the line

, 2010
Heterochromatin is typically highly condensed, gene-poor, and transcriptionally silent, whereas euchromatin is less condensed, gene-rich, and more accessible to transcription.

DNA methylome responses to biotic and abiotic stress in Arabidopsis thaliana: A multi‐study analysis

Plant Biology, EarlyView.
Sixteen Arabidopsis thaliana Whole‐Genome Bisulfite Sequencing datasets have been analysed to reveal common and stress‐specific DNA methylation responses. Although global methylation levels remained stable, specific DMRs varied according to the type of stress and genomics context.
