Phylogenomics of Plasmopara halstedii Reveals Genomic Regions Associated With the Breakdown of Sunflower Downy Mildew Resistance Genes. [PDF]

Mol Ecol
ABSTRACT Understanding the genetic diversity and evolutionary history of plant pathogens is crucial for effective disease management strategies. Sunflower downy mildew, caused by the oomycete Plasmopara halstedii, is a worldwide threat to the sunflower oil crop.

Multidimensional Perspective on the Quality of Green Onion: Between the Visible, the Measurable, and the Perceived. [PDF]

Food Sci Nutr
This graphical abstract presents a five‐phase framework to define green onion quality by integrating literature evidence, physicochemical and bioactive data, digital trends, field damage observations, and consumer perception, providing a multidimensional and measurable quality assessment.

Comparative Metabarcoding of ITS1, ITS2, and Full-Length ITS Reveals Marker- and Tissue-Specific Variation in Fungal Community Profiling in Potato. [PDF]

Plant Environ Interact
ABSTRACT Accurate profiling of plant‐associated fungal and oomycete communities depends critically on the choice of ITS marker. Using Illumina sequencing for ITS1/ITS2 and PacBio HiFi sequencing for full‐length ITS (ITSf), we compared read recovery, taxonomic assignment depth, and diversity patterns across potato leaf and root tissues.

Comparative genomics of downy mildews reveals potential adaptations to biotrophy

BMC Genomics, 2018
Background Spinach downy mildew caused by the oomycete Peronospora effusa is a significant burden on the expanding spinach production industry, especially for organic farms where synthetic fungicides cannot be deployed to control the pathogen. P.

Disentangling Peronospora on Papaver: phylogenetics, taxonomy, nomenclature and host range of downy mildew of opium poppy (Papaver somniferum) and related species.

PLoS ONE, 2014
Based on sequence data from ITS rDNA, cox1 and cox2, six Peronospora species are recognised as phylogenetically distinct on various Papaver species. The host ranges of the four already described species P. arborescens, P. argemones, P.

Short communication: Local infection of opium poppy leaves by Peronospora somniferi sporangia can give rise to systemic infections and seed infection in resistant cultivars

Spanish Journal of Agricultural Research, 2017
Downy mildew (DM) of opium poppy (Papaver somniferum) caused by Peronospora somniferi is one of the most destructive diseases of this crop due to the systemic nature of infection as compared with local infections caused by Peronospora meconopsidis, the ...
