Deciphering recent transposition patterns in plants through comparison of 811 genome assemblies.
Plant Biotechnol J

College of Life Sciences, University of Chinese Academy of Sciences, Beijing, China.
Transposable elements (TEs) are significant drivers of genome evolution, yet their recent dynamics and impacts within and among species, as well as the roles of host genes and non-coding RNAs in the transposition process, remain elusive. With advancements in large-scale pan-genome sequencing and the development of open data sharing, large-scale comparative genomics studies have become feasible. Here, we performed complete de novo TE annotations and identified active TEs in 310 plant genome assemblies across 119 species and seven crop populations.

Hybridization is relatively common between closely related species that share part of their distribution. Understanding its dynamics is important both for conservation purposes and to determine its role as an evolutionary mechanism. Here we have studied the case of black hakes (Merluccius polli and Merluccius senegalensis) in its contact zone.

The surveillance of mobile genetic elements facilitating the spread of antimicrobial resistance genes has been challenging. Here, we tracked both clonal and plasmid transmission in colistin- and carbapenem-resistant using short- and long-read sequencing technologies. We observed three clonal transmissions, all containing Incompatibility group (Inc) L plasmids and New Delhi metallo-beta-lactamase , although not co-located on the same plasmid.

Unlabelled: Archaeal molecular biology has been a topic of intense research in recent decades as their role in global ecosystems, nutrient cycles, and eukaryotic evolution comes to light. The hypersaline-adapted archaeal species and serve as important model organisms for understanding archaeal genomics, genetics, and biochemistry, in part because efficient tools enable genetic manipulation. As a result, the number of strains in circulation among the haloarchaeal research community has increased in recent decades.

In Aotearoa New Zealand, urinary tract infections in humans are commonly caused by extended-spectrum beta-lactamase (ESBL)-producing . This group of antimicrobial-resistant bacteria are often multidrug resistant. However, there is limited information on ESBL-producing found in the environment and their link with human clinical isolates.
