Single and dual RPA‐CRISPR/Cas assays for point‐of‐need detection of Stewart's wilt pathogen (Pantoea stewartii subsp. stewartii) of corn and Maize dwarf mosaic virus

Pest Management Science, Volume 81, Issue 4, Page 1988-1999, April 2025.
Schematic diagram of the single and dual RPA‐CRISPR/Cas12a/13a diagnostic assays for the detection of Pantoea stewartii subsp. stewartii and Maize dwarf mosaic virus. The validated assays provide a useful and sensitive molecular tool for detecting two quarantine pathogens of maize within a minimal resource framework suitable for fast‐tracking the ...

Passive transponder implantation in Theraphosidae: A tool for traceability and conservation

Insect Conservation and Diversity, EarlyView.
PIT TAG microchip implantation was successfully performed in multiple tarantula species, showing high tolerance, rapid recovery from anaesthesia and no mortality associated with the procedure. Microchips remained stable and detectable after successive ecdysis events, with no negative effects on feeding behaviour, development, courtship, mating success ...

Investigation of the global transportation of Culicoides biting midges, vectors of livestock and equid arboviruses, from flower‐packing plants in Kenya

Medical and Veterinary Entomology, Volume 40, Issue 2, Page 260-267, June 2026.
Arboviral diseases spread by Culicoides biting midges have been introduced into Europe by unknown means. A possible route is the carriage of midges with cut flowers shipped to flower markets. We sampled Culicoides in and around a cut flower farm in Kenya; midges were caught in the vicinity and a greenhouse, but not where flowers are processed.

Wild and cultivated Dracaena fragrans

Edinburgh Journal of Botany, 2010
Dracaena fragrans (L.) Ker Gawler is revised, similar species are critically compared and several of them, notably D. deremensis Engl. and D. deisteliana Engl. are reduced into synonymy. A formal classification with standard specimens for cultivated material currently in commerce is proposed.

Homoisoflavonoids—From Natural Specificity and Biosynthesis to Precision Health‐Promoting Mechanisms

Food Frontiers, Volume 7, Issue 3, May 2026.
Homoisoflavonoids are rare flavonoids with a unique bi‐aromatic oxygen‐heterocyclic structure. This review synthesizes their structure–activity relationships in anti‐inflammatory, hypoglycemic, and anticancer contexts. By highlighting their specific natural distribution and outlining biosynthetic pathways, it provides a conceptual framework and ...
