The role of the essential GTPase ObgE in regulating lipopolysaccharide synthesis in Escherichia coli

open access: yesNature Communications
During growth, cells need to synthesize and expand their envelope, a process that requires careful regulation. Here, we show that the GTPase ObgE of E.

Widespread movement of invasive cattle fever ticks (Rhipicephalus microplus) in southern Texas leads to shared local infestations on cattle and deer

open access: yesParasites & Vectors, 2014
Background Rhipicephalus (Boophilus) microplus is a highly-invasive tick that transmits the cattle parasites (Babesia bovis and B. bigemina) that cause cattle fever. R.

Membrane depolarization-triggered responsive diversification leads to antibiotic tolerance

open access: yesMicrobial Cell, 2015
Bacterial populations are known to harbor a small fraction of so-called persister cells that have the remarkable ability to survive treatment with very high doses of antibiotics.

Bio Ethanol Production from Rice Straw Saccharification via Avicelase Gene in E. coli Recombinant Strain

open access: yesClean Technologies, 2023
The most abundant organic carbon source on Earth is cellulosic materials. Its main resources are crop straws which are not commonly used and produce environmental pollution.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Competition quenching strategies reduce antibiotic tolerance in polymicrobial biofilms

open access: yesnpj Biofilms and Microbiomes
Bacteria typically live in dense communities where they are surrounded by other species and compete for a limited amount of resources. These competitive interactions can induce defensive responses that also protect against antimicrobials, potentially ...

Compatibility of Site-Specific Recombination Units between Mobile Genetic Elements

open access: yesiScience, 2020
Summary: Site-specific recombination (SSR) systems are employed for transfer of mobile genetic elements (MGEs), such as lysogenic phages and integrative conjugative elements (ICEs).

Advances in Plant-Nematode Interactions with Emphasis on the Notorious Nematode Genus Meloidogyne. [PDF]

open access: yes, 2019
Plant infections by plant-parasitic nematodes (PPNs) continue to be one of the major limitations in agricultural systems. Root-knot nematodes (RKNs), belonging to the genus Meloidogyne, are one of the most important groups of PPNs worldwide.

Sphagnum physiology in the context of changing climate: emergent influences of genomics, modelling and host-microbiome interactions on understanding ecosystem function. [PDF]

open access: yes, 2014
Peatlands harbour more than one-third of terrestrial carbon leading to the argument that the bryophytes, as major components of peatland ecosystems, store more organic carbon in soils than any other collective plant taxa. Plants of the genus Sphagnum are

Host genetic regulation of human gut microbial structural variation

open access: yesNature
Although the impact of host genetics on gut microbial diversity and the abundance of specific taxa is well established1–6, little is known about how host genetics regulates the genetic diversity of gut microorganisms. Here we conducted a meta-analysis of
