Large-scale protein interactome reveals lineage-specific genes driving plant-parasitic nematode adaptive innovations.

Mounting evidence suggests that lineage-specific genes drive phenotype diversity. Plant-parasitic nematodes (PPNs), among the most destructive plant pathogens, have evolved innovated traits required for plant parasitism, yet the genetic basis remains unclear. Here, we identify PPN lineage-specific genes (PPNLSGs) and analyze the large-scale protein interactome of their encoded proteins (PPNLSPs).

Integrative multi-omics analysis reveals the translational landscape of the plant-parasitic nematode Meloidogyne incognita.

Root-knot nematodes (RKNs) of the genus Meloidogyne pose the most significant threats to global food security due to their destructive nature as plant-parasitic nematodes. Although significant attention has been devoted to investigating the gene transcription profiling of RKNs, our understanding of the translational landscape of RKNs remains limited. In this study, we elucidated the translational landscape of Meloidogyne incognita through the integration of translatome, transcriptome and quantitative proteome analyses.

Root-knot nematodes exploit the catalase-like effector to manipulate plant reactive oxygen species levels by directly degrading HO.

Plants produce reactive oxygen species (ROS) upon infection, which typically trigger defence mechanisms and impede pathogen proliferation. Root-knot nematodes (RKNs, Meloidogyne spp.) represent highly detrimental pathogens capable of parasitizing a broad spectrum of crops, resulting in substantial annual agricultural losses.

KDM5C-Mediated Recruitment of BRD4 to Chromatin Regulates Enhancer Activation and BET Inhibitor Sensitivity.

Unlabelled: The BET family member BRD4 is a bromodomain-containing protein that plays a vital role in driving oncogene expression. Given their pivotal role in regulating oncogenic networks in various cancer types, BET inhibitors (BETi) have been developed, but the clinical application has been impeded by dose-limiting toxicity and resistance. Understanding the mechanisms of BRD4 activity and identifying predictive biomarkers could facilitate the successful clinical use of BETis.

Unzipped chromosome-level genomes reveal allopolyploid nematode origin pattern as unreduced gamete hybridization.

The formation and consequences of polyploidization in animals with clonal reproduction remain largely unknown. Clade I root-knot nematodes (RKNs), characterized by parthenogenesis and allopolyploidy, show a widespread geographical distribution and extensive agricultural destruction. Here, we generated 4 unzipped polyploid RKN genomes and identified a putative novel alternative telomeric element.

Analysis Highlights the Diversity and Novelty of Circular Bacteriocins in Sequenced Microbial Genomes.

Consumer demand for "fresh food" with no chemical preservatives has prompted researchers to pay more attention to natural antimicrobial peptides such as bacteriocins. Nisin is currently the most widely used food biopreservative among the bacteriocins; however, its applications are restricted due to its low stability at neutral and alkaline pH values. Circular bacteriocins have potent antimicrobial activity against foodborne pathogens, show exceptional stability, and have great potential to be developed as biopreservatives.

The CRISPR-Cas systems were selectively inactivated during evolution of Bacillus cereus group for adaptation to diverse environments.

CRISPR-Cas systems are considered as barriers to horizontal gene transfer (HGT). However, the influence of such systems on HGT within species is unclear. Also, little is known about the impact of CRISPR-Cas systems on bacterial evolution at the population level.
