We began 2025 on a positive note with the publication of our latest research in PhytoFrontiers. Our work provides valuable genomic resources for Botrytis cinerea affecting strawberries and blueberries apsjournals.apsnet.org/doi/10.1094/PH…

Recent surveys identified disease ID and management as top priorities for hemp research. Derrick J. Grunwald et al. developed a multiplex reverse transcription PCR protocol to detect this viroid and viruses from hemp leaf samples. UW Plant and Agroecosystem Sciences CSU College of Agricultural Sciences doi.org/10.1094/PHYTOF…

Shao et al. built the Plant-Associated VOC Database to facilitate research on VOCs released by plants and plant-associated microbes. This platform presents the physicochemical characteristics, biosynthetic pathways, and more. Kellogg Research Group Paul Esker doi.org/10.1094/PHYTOF…

This study by Hannah M. Rivedal et al. indicates the utility of incorporating molecular methods for risk evaluations of seed gall nematodes (SGNs) and provides recommendations for accurate SGN detection throughout the growing season in Oregon. doi.org/10.1094/PHYTOF…

Potato virus Y (PVY) remains a major threat in the San Luis Valley (SLV), CO. This study by Jennifer Rushton and others provides valuable insights into the evolving PVY landscape and the complex potato virome in SLV. CSU College of Agricultural Sciences Learn more: doi.org/10.1094/PHYTOF…

A subspecies of Xylella fastidiosa was detected in coffee plants imported from Costa Rica in Europe. María Pilar Velasco-Amo et al. sequenced complete genomes for two strains, aiding comparative genomic and population analysis. Blanca B. Landa doi.org/10.1094/PHYTOF…

Our publication on #lettucewilt #diagnostics is in first look PhytoFrontiers™. We designed qPCR and RPA assays to rapidly detect Globisporangium uncinulatum (Pythium uncinulatum) in lettuce and soil samples. apsjournals.apsnet.org/doi/epdf/10.10

Rebecca Harkness et al. conducted a study of 1,080 root samples from 15 California nurseries, finding 22% infected by Phytophthora spp. ImmunoStrips had 30% false positives but helped flag samples for qPCR confirmation. Timothy Miles doi.org/10.1094/PHYTOF…

Lucas N. dos Santos et al. consolidate recent findings on the role of NAC as a potent antioxidant molecule in mitigating both biotic and abiotic stresses in plants, highlighting its valuable contributions to sustainable agriculture. Read the Review: doi.org/10.1094/PHYTOF…
