Comparison of plant microbiota in diseased and healthy rice reveals methylobacteria as health signatures with biocontrol capabilities.

Introduction: Rice () is a staple food worldwide, but its production is under constant pressure from both abiotic and biotic stresses, resulting in high use of agrochemicals. The plant microbiome harbours microorganisms that can benefit plant health and provide alternatives to the use of agrochemicals. The composition of plant microbiomes depends on many factors (soil composition, age, and health) and is considered a primary driver of future plant health.

Assessing RNA integrity by digital RT-PCR: Influence of extraction, storage, and matrices.

The development of high-throughput sequencing has greatly improved our knowledge of microbial diversity in aquatic environments and its evolution in highly diverse ecosystems. Relevant microbial diversity description based on high-throughput sequencing relies on the good quality of the nucleic acid recovered. Indeed, long genetic fragments are more informative for identifying mutation combinations that characterize variants or species in complex samples.

Effect of volumetric concentration factor on virus removal for low-pressure reverse osmosis membrane in drinking water production: A study on different scales.

Reverse osmosis membranes are intended to constitute a complete physical barrier against nanometric-sized pathogens such as enteric viruses. Literature describes that low-pressure reverse osmosis achieves high viral removal rates (above 5 log), surpassing those of ultrafiltration (1 to 3 log). However, these studies often used individual viruses and high feed viral concentrations (above 10 virus L), greater than typical viral concentrations present in the environment like groundwater, to promote virus detection in the permeate.

Phylogeography of horseshoe bat sarbecoviruses in Vietnam and neighbouring countries. Implications for the origins of SARS-CoV and SARS-CoV-2.

Previous studies on horseshoe bats (Rhinolophus spp.) have described many coronaviruses related to SARS-CoV (SARSCoVr) in China and only a few coronaviruses related to SARS-CoV-2 (SARSCoV2r) in Yunnan (southern China), Cambodia, Laos and Thailand. Here, we report the results of several field missions carried out in 2017, 2021 and 2022 across Vietnam during which 1218 horseshoe bats were sampled from 19 locations.
