A module with multiple transcription factors positively regulates powdery mildew resistance in grapevine

Plant Biotechnology Journal, EarlyView.
Summary Erysiphe necator, the causal agent of powdery mildew (PM), is a fungal pathogen that can severely reduce crop yields. In this study, stable overexpression and silencing demonstrated that the transcription factor VqWRKY46 was identified as a positive regulator of PM resistance in grapevine.

Zoospore diversity and sexual reproduction in the lichen‐forming genus Trebouxia: From neglected evidence to new facts

Plant Biology, EarlyView.
This study clarifies the role of flagellate cells in four Trebouxia species. Using innovative techniques, we could distinguish between zoospores and gametes, providing the first detailed evidence of sex. Abstract Trebouxia is one of the most frequent genera of green microalgae that occur as photobionts in lichens.

Are lichens biocompasses? Revisiting an old prediction using new techniques

Plant Biology, EarlyView.
The equator‐facing portions of tree trunks receive direct sunlight and create restrictive microclimate conditions for lichens that orient preferentially towards the Earth's poles where trunks are shaded, indicating an optimal zone at the fine‐scale radial dimension.

A Group 6 LEA Protein Plays Key Roles in Tolerance to Water Deficit, and in Maintaining the Glassy State and Longevity of Seeds

Plant, Cell &Environment, Volume 48, Issue 9, Page 6874-6896, September 2025.
ABSTRACT Plants have a wide range of adaptive and protective mechanisms to cope with dehydration. Central in these processes are the Late Embryogenesis Abundant (LEA) proteins, whose levels notably increase in response to dehydration during seed development and vegetative tissues.

ParAquaSeq, a Database of Ecologically Annotated rRNA Sequences Covering Zoosporic Parasites Infecting Aquatic Primary Producers in Natural and Industrial Systems

Molecular Ecology Resources, Volume 25, Issue 6, August 2025.
ABSTRACT Amplicon sequencing tools such as metabarcoding are commonly used for thorough characterisation of microbial diversity in natural samples. They mostly rely on the amplification of conserved universal markers, mainly ribosomal genes, allowing the taxonomic assignment of barcodes.

Improving Whole Biodiversity Monitoring and Discovery With Environmental DNA Metagenomics

Molecular Ecology Resources, Volume 25, Issue 6, August 2025.
ABSTRACT Environmental DNA (eDNA) metagenomics sequences all DNA molecules present in environmental samples and has the potential of identifying virtually any organism from which they are derived. However, due to unacceptable levels of false positives and negatives, this approach is underexplored as a tool for biodiversity monitoring across the tree of

DNA Metabarcoding Focusing on Eukaryote Communities on Langhovde Glacier, East Antarctica

Environmental Microbiology Reports, Volume 17, Issue 4, August 2025.
Based on comprehensive 18S rRNA gene analysis, this study characterises the eukaryotic communities inhabiting the supraglacial environments of Langhovde Glacier, East Antarctica, in relation to the associated aquatic chemistry. Genetic differences between organisms found in the surrounding ice‐free areas and those in distant snow and ice fields are ...

Seasonal Transition in the Dominance of Photoautotrophic and Heterotrophic Protists in the Photic Layer of a Subtropical Marine Ecosystem

Environmental Microbiology Reports, Volume 17, Issue 4, August 2025.
Amplicon sequencing showed a distinct seasonality in protist communities and functional strategies in a subtropical ecosystem in the Gulf of Aqaba. Temperature and nutrients were major drivers of succession. Comparisons with oceanwide Tara‐Ocean datasets indicated that the summer‐oligotrophic protist assemblages from the Gulf of Aqaba resemble those ...

Freshwater Discharge and Salinity Drive Taxonomic and Functional Turnover of Microbial Communities in a Turbid Macrotidal Estuary

Environmental Microbiology Reports, Volume 17, Issue 4, August 2025.
Seasonal shifts in microbial community composition in the Schelde estuary are controlled by the interaction between freshwater discharge and marine intrusion. However, these recurrent annual patterns can be disrupted by extreme precipitation events.
