Analysis of the heterogenous structural states of the hexameric ATPase PilU of the type IV pili from Vibrio cholerae

Protein Science, Volume 35, Issue 6, June 2026.
Abstract Type IV pili (T4P) mediate surface motility, host interactions, and DNA uptake through cycles of extension and retraction. While the primary retraction ATPase PilT has been extensively characterized, its homolog PilU remains less well understood despite being demonstrated as a PilT‐dependent retraction ATPase.

Long‐Term Management Shapes Soil Microbial Communities Primarily Through Modulating Soil Habitat Quality in Swiss Croplands

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 2, June 2026.
ABSTRACT Soil microbial communities are key drivers of soil functioning in agricultural systems. Yet the relative influence of soil properties and cropping practices on their diversity remains insufficiently understood. We investigated 60 cropland sites in western Switzerland, covering a broad range of soil properties and cropping practices, to explore

High Resistance and Biofilm Tolerance to Antimicrobials of Marine Bacteria From Brazilian Deep‐Sea Sediment

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Antimicrobial resistance and biofilm‐specific tolerance of cultivable Pseudomonas, Bacillus, Brevibacillus and Paenibacillus isolated from deep‐sea sediments of a methane‐seep area off the Southern Brazilian coast. These findings underscore the role of deep‐sea environments as potential reservoirs for antimicrobial‐resistant bacteria (ARB) and ...

Endophytic and ectomycorrhizal, an overlooked dual ecological niche? Insights from natural environments and Russula species

New Phytologist, Volume 250, Issue 6, Page 3946-3960, June 2026.
Summary Ectomycorrhizal fungi (EcMF) are key components of temperate ecosystems, and recent studies suggest that they can also inhabit non‐EcM plant roots as endophytes. We aimed to (1) provide new evidence of EcMF colonization of non‐EcM hosts, (2) offer direct microscopic confirmation of such endophytism and (3) assess factors influencing ...

Pensar con y a partir del operón

Revista Colombiana de Filosofía de la Ciencia
Este artículo sostiene que el operón lac propuesto por François Jacob y Jacques Monod en 1961 superó los campos de la cinética enzimática y la genética bacteriana en los que se estableció originalmente porque impulsó una metodología de análisis, el ...

An Engineered Living Material With Pro‐Angiogenic Activity Inducible by Near‐Infrared Light

Advanced Functional Materials, Volume 36, Issue 40, 18 May 2026.
NIR‐responsive engineered living materials (ELMs) for controlled angiogenesis: Near‐infrared (800 nm) light activates engineered probiotic bacteria within alginate‐based living materials to secrete a blood vessel‐regenerating protein. The released protein promotes pro‐angiogenic effects in endothelial networks and chick chorioallantoic membranes.

Coordination of Cyanobacterial Nitrate Assimilation and Photosynthesis by a Novel PsbO‐Interacting Protein PirN

Advanced Science, Volume 13, Issue 29, 22 May 2026.
PirN was identified as a previously uncharacterized PsbO‐interacting protein specifically induced in nitrate‐grown cyanobacteria. Loss of PirN leads to coordinated downregulation of PsbO and the nitrate reductase NarB, causing decreased PSII activity and impaired growth under nitrate conditions. Complementation with either PsbO or NarB largely restores

Bioenergy Cropping Reduces the Spatiotemporal Scaling of Soil Bacterial Biodiversity

Advanced Science, Volume 13, Issue 29, 22 May 2026.
Consistent with patterns observed in plant and animal communities, soil bacterial communities exhibit significant species–time–area and phylogenetic–time–area relationships independent of nested structure. Bioenergy cropping significantly reduces the spatiotemporal scaling rates, particularly in sandy loam soils.

Failed "nonaccelerating" models of prokaryote gene regulatory networks

, 2004
Much current network analysis is predicated on the assumption that important biological networks will either possess scale free or exponential statistics which are independent of network size allowing unconstrained network growth over time. In this paper,
