Exploring the Antifungal Potential of the Brown Macroalga Hormophysa triquetra: Morphological Disruptions and Structural Changes in Plant Pathogens

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Extracts of Hormophysa triquetra showed antifungal activity with marked hyphal deformities in Fusarium oxysporum and Alternaria alternata. Light microscopy and SEM confirmed structural alterations despite unchanged radial growth. Cucumber assays validated reduced disease incidence, linked to fatty‐acid–rich metabolites detected by GC–MS.

An antiviral jacalin‐like lectin gene contributes to nonhost resistance and host determination of potexviruses among Brassicaceae

open access: yesNew Phytologist, Volume 250, Issue 5, Page 3283-3298, June 2026.
Summary Plant resistance influences the host range of pathogens; however, the mechanism driving this influence remains poorly understood. Brassicaceae species are not natural hosts of potexviruses, for reasons that have not yet been determined. This study investigated the molecular basis of nonhost resistance (NHR) to potexviruses in the Brassicaceae ...
