Insights on the regulation and function of the CRISPR/Cas transposition system located in the pathogenicity island VpaI-7 from Vibrio parahaemolyticus RIMD2210633

open access: yesInfection and Immunity
CRISPR/Cas-mediated transposition is a recently recognized strategy for horizontal gene transfer in a variety of bacterial species. However, our understanding of the factors that control their function in their natural hosts is still limited.

Molecular mechanisms of sex determination in Lepidoptera: current status and perspectives

open access: yesInsect Science, EarlyView.
The genetic basis of sex determination in Lepidoptera was discovered in 2014 in the silkworm Bombyx mori. In this model species, the W chromosome‐derived small piRNA called Fem piRNA downregulates the expression of a Z‐linked gene, Masculinizer (Masc), which leads to the default female‐specific splicing of the doublesex gene (dsxF) and thus to female ...

A Family of Developmentally Excised DNA Elements in \u3cem\u3eTetrahymena\u3c/em\u3e is under Selective Pressure to Maintain an Open Reading Frame Encoding an Integrase-Like Protein [PDF]

open access: yes, 2000
Tlr1 is a member of a family of ~20-30 DNA elements that undergo developmentally regulated excision during formation of the macronucleus in the ciliated protozoan Tetrahymena.

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

open access: yesInsect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

Genomic analysis of the Staphylococcus pseudintermedius mobilome associated with antimicrobial resistance

open access: yesFrontiers in Microbiology
The increasing antimicrobial resistance (AMR) in Staphylococcus pseudintermedius causing skin and soft-tissue infections (SSTIs) in companion animals is a public health concern.

Neoclassical development of genetic sexing strains for insect pest and disease vector control

open access: yesInsect Science, EarlyView.
The sterile insect technique has been effectively used for decades, and an important component is the availability of sex separation systems, in particular genetic sexing strains. Classical approaches, such as irradiation‐induced chromosomal translocations, have yielded stable strains for species like the Mediterranean fruit fly.

Detection of sex chromosomes in Tephritid pests using R‐CQ and KAMY, two computational methods to support generic pest management applications

open access: yesInsect Science, EarlyView.
Here, we present R‐CQ and KAMY, two computational methods developed for the detection of sex chromosome‐linked sequences. We evaluate their performance on newly generated chromosome‐level assemblies of four important Tephritid pest species: Ceratitis capitata, Bactrocera dorsalis, Bactrocera zonata, and Anastrepha ludens.
