Biosynthesis of thiocarboxylic acid-containing natural products. [PDF]

open access: yes, 2018
Thiocarboxylic acid-containing natural products are rare and their biosynthesis and biological significance remain unknown. Thioplatensimycin (thioPTM) and thioplatencin (thioPTN), thiocarboxylic acid congeners of the antibacterial natural products ...

Altered Nasal Microbiota in Sinonasal Tumors: A Comparative Analysis of Malignant and Benign Sinonasal Tumors

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Although shifts in nasal microbiota have been well‐documented in inflammatory upper airway conditions, microbiota tumor‐associated alterations remain uncharacterized. This study is the first to compare sinonasal microbiota profiles of patients with malignant tumors (MT), benign tumors (BT), and controls, offering insights into tumor‐

Soil Microbial Networks Shift Across a High-Elevation Successional Gradient. [PDF]

open access: yes, 2019
While it is well established that microbial composition and diversity shift along environmental gradients, how interactions among microbes change is poorly understood.

Exploring Actinobacteria Associated With Rhizosphere and Endosphere of the Native Alpine Medicinal Plant Leontopodium nivale Subspecies alpinum

open access: yesFrontiers in Microbiology, 2019
The rhizosphere of plants is enriched in nutrients facilitating growth of microorganisms, some of which are recruited as endophytes. Endophytes, especially Actinobacteria, are known to produce a plethora of bioactive compounds.

The ageing holobiont: crosstalk between telomere dynamics, oxidative stress and the gut microbiome

open access: yesBiological Reviews, EarlyView.
ABSTRACT The gut tissue is at the frontline of early onset of ageing. It exhibits high cell turnover rates and rapid telomere shortening, which can have systemic effects on the developing or senescing organism. We conducted a literature review of studies on the crosstalk between telomere length dynamics, telomerase activity, oxidative stress, and gut ...

Initiator tRNA genes template the 3\u27 CCA end at high frequencies in bacteria. [PDF]

open access: yes, 2016
BACKGROUND: While the CCA sequence at the mature 3\u27 end of tRNAs is conserved and critical for translational function, a genetic template for this sequence is not always contained in tRNA genes.

Depth‐dependent mechanisms regulate accumulation of plant‐ and microbial‐derived residues under long‐term nitrogen addition in a semiarid grassland

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant‐ and microbial‐derived residues constitute the primary sources of soil organic carbon (SOC) in grassland ecosystems. However, their differential responses to chronic nitrogen (N) enrichment and the depth‐dependent mechanisms governing their accumulation remain ...

Ecological succession of a Jurassic shallow-water ichthyosaur fall. [PDF]

open access: yes, 2014
After the discovery of whale fall communities in modern oceans, it has been hypothesized that during the Mesozoic the carcasses of marine reptiles created similar habitats supporting long-lived and specialized animal communities.

Diversity and antimicrobial activity of culturable actinobacteria isolated from the sediment of Sarıkum Lake

open access: yesBiotechnology & Biotechnological Equipment, 2021
In this study, actinobacteria isolated from Sarıkum Lake sediment were characterized (Sinop-Turkey). A total of 48 actinobacteria were isolated using ten selective media with the dilution-plating method.

The grapevine microbiota: A review on the possible impacts of plant protection programs on phyllosphere microorganisms

open access: yesAnnals of Applied Biology, EarlyView.
This review highlights recent advances in understanding how plant protection programs and alternative fungicides affect the taxonomic composition of the grapevine phyllosphere microbiota. Bacterial and fungal communities are primarily shaped by the plant compartment, vineyard location, and sampling time. Plant protection programs generally have a minor
