The DNA methylation landscape of the root-knot nematode-induced pseudo-organ, the gall, in Arabidopsis, is dynamic, contrasting over time, and critically important for successful parasitism.

Root-knot nematodes (RKNs) induce giant cells (GCs) within galls which are characterized by large-scale gene repression at early stages. However, the epigenetic mechanism(s) underlying gene silencing is (are) still poorly...

Transposition
CRISPR-Cas systems provide sequence-specific immunity against selfish genetic elements in prokaryotes. Now, two studies show that transposon-encoded variants can guide sequence-specific transposition. These findings have...
Screening for Highly Transduced Genes in Staphylococcus aureus Revealed Both Lateral and Specialized Transduction.

Bacteriophage-mediated transduction of bacterial DNA is a major route of horizontal gene transfer in the human pathogen, Staphylococcus aureus. Transduction involves the packaging of bacterial DNA by viruses and enables the...
Becoming a Selfish Clan
Transposable elements (TEs) are parasitic DNA bits capable of mobilization and mutagenesis, typically suppressed by host's epigenetic silencing. Since the selfish DNA concept, it is appreciated that genomes are also molded by...

Prions are often considered as molecular memory devices, generating reproducible memory of a conformational change. Prion-like proteins (PrLPs) have been widely demonstrated to be present in plants, but their role in plant...
