Cucurbit yellow stunting disorder virus (CYSDV), genus Crinivirus and family Closteroviridae, has emerged as a serious whitefly-transmitted virus of cucurbit crops, causing between 30 and 50% yield losses. Development of resistant cultivars represents an economically and environmentally sound approach to management of this disease. In all, 124 cucumber accessions were evaluated for reaction to CYSDV under high inoculum pressure over three growing seasons. Seven accessions showed delayed expression of symptoms, milder final symptoms, and lower percentages of infected plants compared with susceptible cucumbers. Although none of these accessions were immune to CYSDV, virus concentrations in the middle leaves of the tolerant accessions were significantly lower than those of susceptible accessions.

Potyviral P3 is involved in viral replication, movement, and pathogenicity; however, its biochemical function is unknown. In this study, the P3 of the zucchini yellow mosaic virus (ZYMV) interacted with ClBBD, a protein with high ortholog bifunctional nuclease activity, in watermelon. The binding site was shown via yeast two-hybrid screening and BiFC assay to be located at the N-terminus of P3 rather than P3N-PIPO.

Article Synopsis
- Passion fruit, an economically significant crop in Guangxi, China, experienced a blossom blight epidemic in September 2022, affecting about 30% of plants in a 2.5 ha area.
- The disease resulted in initial water-soaked spots on flowers that progressed to wet rot, characterized by white mycelia and dark sporangia.
- Three fungal isolates linked to the illness were identified as Choanephora cucurbitarum based on their morphological features and genetic sequencing, confirming the fungus's identity through a high degree of similarity in ribosomal DNA sequences.

Article Synopsis
- - Bur cucumber, an invasive species in South Korea, was surveyed in July 2024, revealing that around 5% of the plants showed viral symptoms like yellowing and mosaic patterns across five southeastern regions.
- - Researchers collected 25 leaf samples for RT-PCR testing to identify nine common cucurbit viruses, finding that Watermelon Mosaic Virus (WMV) was present in 16 samples and co-infection with Cucurbit Aphid-Borne Yellows Virus (CABYV) in 6 samples.
- - Symptoms varied, with WMV causing mosaic patterns and more severe yellowing seen in co-infected samples, highlighting the need for monitoring both viruses due to their combined effects on plant health and agricultural yield

Article Synopsis
- The pathogenesis-related 1 (ClPR1) gene in watermelon plays a crucial role in resisting Zucchini yellow mosaic virus (ZYMV), as evidenced by reduced virus accumulation in a resistant watermelon line (938-16-B) compared to a susceptible line (H1).
- Grafting experiments indicated that resistance signals can be transferred from the resistant line (938-16-B) to susceptible varieties, leading to hypersensitivity response (HR) induction.
- ClPR1 expression is uniquely activated in the resistant line after ZYMV infection, and while its overexpression reduces virus accumulation in susceptible lines, it does not trigger HR, linking ClPR1 to the resistance mechanism against ZYMV.
