Loss of pod shattering is one of the most important domestication-related traits in legume crops. The non-shattering phenotypes have been achieved either by disturbed formation of abscission layer between the valves, or by loss of helical tension in sclerenchyma of endocarp, that split open the pods to disperse the seeds. During domestication, azuki bean () and yard-long bean ( cv-gr.

We have developed and characterized a bacterial consortium that reductively dechlorinates trichloroethene to ethene. Quantitative PCR analysis for the 16S rRNA and reductive dehalogenase genes showed that the consortium is highly enriched with Dehalococcoides spp. that have two vinyl chloride reductive dehalogenase genes, bvcA and vcrA, and a trichloroethene reductive dehalogenase gene, tceA.

Article Synopsis
  • - A carbapenem-resistant strain of *Pseudomonas aeruginosa*, known as NCGM1984, was identified in 2012 from a Japanese patient and showed the presence of IMP-type metallo-β-lactamase through immunochromatographic assays.
  • - Genome sequencing revealed that NCGM1984 contained two copies of the *blaIMP-34* gene located on different sites of its chromosome, both part of a complex genetic structure with multiple associated genes.
  • - The strain was classified as multilocus sequence typing ST235, noted as a high-risk clone, and the IMP-34 variant exhibited catalytic properties similar to IMP-1, hydrolyzing almost all tested β-lactam antibiotics

Fluvirucins are 14-membered macrolactam polyketides that show antifungal and antivirus activities. Fluvirucins have the β-alanine starter unit at their polyketide skeletons. To understand the construction mechanism of the β-alanine moiety in fluvirucin biosyntheses, we have identified the biosynthetic cluster of fluvirucin B2 produced from Actinomadura fulva subsp.

  • Second-generation sequencers (SGS) have made whole genome sequencing affordable for many non-model organisms, but many genomes remain unassembled.
  • Researchers used single molecule real-time (SMRT) sequencing to reconstruct the azuki bean genome, achieving superior contiguity and coverage compared to SGS-based assemblies.
  • The SMRT assembly produced longer contigs with fewer gaps, leading to better gene annotations and covering 86% of the azuki bean genome, demonstrating its effectiveness even when combined with SGS data.

Chemosynthetic symbiosis is one of the successful systems for adapting to a wide range of habitats including extreme environments, and the metabolic capabilities of symbionts enable host organisms to expand their habitat ranges. However, our understanding of the adaptive strategies that enable symbiotic organisms to expand their habitats is still fragmentary. Here, we report that a single-ribotype endosymbiont population in an individual of the host vent mussel, Bathymodiolus septemdierum has heterogeneous genomes with regard to the composition of key metabolic gene clusters for hydrogen oxidation and nitrate reduction.
