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).

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.

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.

Root-knot nematodes (RKNs) are plant pests that infect the roots of host plants. Bacillus thuringiensis (Bt) nematicidal proteins exhibited toxicity to nematodes. However, the application of nematicidal proteins for plant protection is hampered by the lack of effective delivery systems in transgenic plants.

Article Synopsis
  • * Researchers recorded 11 embryonic developmental stages of three nematode species (Meloidogyne incognita, Heterodera glycines, and Ditylenchus destructor) and used a cutting-edge method called smart-seq2 to create transcriptome datasets from single embryos.
  • * The study resulted in a total of 162 detailed transcriptome libraries across all stages, providing valuable data to understand nematode embryogenesis and identify key regulatory genes involved in their development.

Pseudomonas fluorescens group, such as Pseudomonas protegens and Pseudomonas chlororaphis, can be utilized as insect-killing agents. Most insecticidal Pseudomonas described so far have high toxicity for insects of the order Lepidoptera. In this study, Pseudomonas strain PcR3-3 was isolated from the willow root.

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.

Article Synopsis
  • Ferromanganese nodule-bearing deep-sea sediments in the Clarion-Clipperton Fracture Zone create a unique habitat for microorganisms, with high iron levels and low degradable nutrients that challenge survival.
  • Analysis of seven sediment samples led to the reconstruction of 179 metagenome-assembled genomes, revealing a diverse microbial community primarily classified into 21 bacterial phyla and 1 archaeal phylum, with most remaining unclassified at the species level.
  • Microorganisms in these sediments utilize various mechanisms to resist heavy metals and rely on redox reactions to obtain energy, indicating that chemical processes involving metals and sulfur compounds are key survival strategies in this extreme environment.

Background: Due to the detrimental effects of chemical preservatives, there has been an increasing demand for safer, healthier and natural bio-preservatives. Bacteriocins have attracted increasing interest because of their potential as natural bio-preservatives.

Results: We screened a large number of Bacillus thuringiensis strains and isolated one strain (B.

The Gram-stain-negative, aerobic, ovoid or rod-shaped bacterial strain, designated KN286, was isolated from seawater of tropical western Pacific. Growth occurred between 15 and 40 °C (optimally at 30-35 °C), pH 6-9 (optimally at 7.0) and in the presence of 0.

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.
