From photoprotection to plasticity: transposon activation in the Chlamydomonas det1 mutant

New Phytologist, EarlyView.
Summary Transposable elements (TEs) contribute to genomic adaptation but are typically silenced to maintain genome integrity. In this study, we investigated TE activation in a Chlamydomonas reinhardtii mutant deficient in DE‐ETIOLATED1 (DET1).

High-resolution mapping of heterochromatin redistribution in a Drosophila position-effect variegation model

Epigenetics & Chromatin, 2009
Background Position-effect variegation (PEV) is the stochastic transcriptional silencing of a gene positioned adjacent to heterochromatin. white-mottled X-chromosomal inversions in Drosophila are classic PEV models that show variegation of the eye color ...

DNA demethylation and heterochromatin remodelling upon heat stress [PDF]

, 2012
Conversion of environmental signals into epigenetic information is thought to occur widely but has been poorly studied as yet. It is proposed that changes in the expression of molecules involved in chromatin remodelling or their modification might play a

Polymorphic organization of constitutive heterochromatin in Equus asinus (2n = 62) chromosome 1.

Hereditas, 2011
In the karyotype of Equus asinus (domestic donkey, 2n = 62), non-centromeric heterochromatic bands have been described in subcentromeric and telomeric positions. In particular, chromosome 1 is characterised by heterochromatic bands in the proximal region

JMJ720 regulates flowering time in rice via H3K9 demethylation of Hd1

Plant Biotechnology Journal, EarlyView.
Summary Heading date is a crucial agronomic trait that determines the adaptability of rice to specific planting regions and seasons. Although numerous heading date genes have been well characterized in rice, epigenetic regulation of flowering time remains limited.

Epigenetic regulation modulates seasonal temperature‐dependent growth of soybean in southern China

Plant Biotechnology Journal, EarlyView.
Summary Epigenetic variations, including DNA methylation and small RNAs, are crucial for plant stress adaptation. However, their association with soybean adaptation to natural environments remains unclear. Through multi‐omics analyses, we investigate soybeans from distinct geographical regions (Northern China: HH43, Southern China: HX3, and Wm82) and ...

Chromatin insulator elements: establishing barriers to set heterochromatin boundaries [PDF]

, 2012
Epigenomic profiling has revealed that substantial portions of genomes in higher eukaryotes are organized into extensive domains of transcriptionally repressive chromatin.

Differentiation Trajectory of Virus‐Induced Tumour Cells in Rice Revealed by Single‐Cell RNA Sequencing

Plant Biotechnology Journal, EarlyView.
ABSTRACT Many plant viruses trigger abnormal differentiation and development of host cells, causing distinct symptoms. Here, in a single‐cell RNA sequence analysis, we find transcriptional heterogeneity between cells from rice leaf sheaths that are infected with rice black streaked dwarf virus (RBSDV) and from those that are virus‐free.

A CRY-BIC negative-feedback circuitry regulating blue light sensitivity of Arabidopsis. [PDF]

, 2017
Cryptochromes are blue light receptors that regulate various light responses in plants. Arabidopsis cryptochrome 1 (CRY1) and cryptochrome 2 (CRY2) mediate blue light inhibition of hypocotyl elongation and long-day (LD) promotion of floral initiation. It
