Cover Story: Potyviruses are a major cause of yield loss in cultivated cucurbits worldwide. In this paper, we describe the first virome analysis of severely symptomatic zucchini and cucumber samples in continental Croatia, employing high-throughput sequencing and RT‑PCR. A mix of potyviruses consisting of watermelon mosaic virus (WMV), zucchini yellow mosaic virus (ZYMV), and Moroccan watermelon mosaic virus (MWMV) were major constituents of the viromes. Notably, MWMV was identified for the first time in Croatia—likely its northernmost record. These findings underscore the expanding reach of MWMV and the power of HTS for pathogen surveillance. The results have implications for cucurbit disease management: re‑examining cultivar resistance, intensifying phytosanitary monitoring, and assessing the role of climate‑driven aphid vectors in virus spread. View this paper
