The nucleotide (nt) sequences of the coat protein (CP) genes of two Japanese zucchini yellow mosaic virus (ZYMV) isolates (ZYMV-169 and ZYMV-M) were determined. The CP genes of both isolates were 837 nt long and encoded 279 amino acids (aa). The nt and deduced aa sequence similarities between the two isolates were 92% and 94.6%, respectively. The deduced aa sequences of CPs of the Japanese isol...

The infectious full-length cDNA clone of zucchini yellow mosaic virus (ZYMV) isolate PA (pZYMV-PA), which was isolated from pumpkin, was constructed by utilizing viral transcription and processing signals to produce infectious in vivo transcripts. Simple rub-inoculation of plasmid DNAs of pZYMV-PA was successful to cause infection of zucchini plants (Cucurbita pepo L.). We further engineered th...

Both biotic and abiotic stressors can elicit broad-spectrum plant resistance against subsequent pathogen challenges. However, we currently have little understanding of how such effects influence broader aspects of disease ecology and epidemiology in natural environments where plants interact with multiple antagonists simultaneously. In previous work, we have shown that healthy wild gourd plants...

High resistance to zucchini yellow mosaic virus-China strain (ZYMV-CH) and moderate resistance to watermelon mosaic virus (WMV) were found in a selection of PI 595203 (Citrullus lanatus var. lanatus), an Egusi type originally collected in Nigeria. Mixed inoculations showed primarily that these two viruses have no cross-protection. This fact may explain the high frequency of mixed infection ofte...

The complete nucleotide sequence of Zucchini yellow mosaic virus isolate from Egypt (ZYMV-Egz_MT383108) was determined. comparisons suggested that the belongs to Group A. analysis Egyptian showed highest similarity (~96-97%) with isolates leaf1 (KJ923767.1) and PA_2006 (JQ716413.1) USA lowest (84%) an (AF014811.2) Singapore. phylogenetic revealed ZYMV-Egz occupied a distinct clade together in A...

Aim. Screening of vegetable crops for mixed viral infections caused by 8 viruses, and evaluation relative share different combinations pathogens using serological methods plant virus diagnostics. Methods. Double-antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA) was performed detection antigens. Results. For this study, the samples from plants with virus-like symptoms were collecte...

ویروس موزائیک زرد کدو (ZYMV) از ویروس­های مهم کدوئیان است. پروتیین پوششی (Coat Protein, CP) پوتی­ویروس­ها به لحاظ تبارزایی حائز اهمیت است و از سوی دیگر منطقه ورامین نیز از مناطق مهم تولید کدوئیان بشمار می­آید، اما تاکنون ناحیه ZYMV-CP در جدایه­های این منطقه تعیین­ توالی نشده است. بنابراین، هدف این پژوهش، تعیین­ توالی ZYMV-CP در جدایه­ های ورامین و بررسی روابط فیلوژنتیکی آن با دیگر جدایه­های ZYM...

The 2b protein encoded by Cucumber mosaic virus (CMV) has been shown to be a silencing suppressor and pathogenicity determinant in solanaceous hosts, but a movement determinant in cucumber. In addition, synergistic interactions between CMV and Zucchini yellow mosaic virus (ZYMV) have been described in several cucurbit species. Here, it was shown that deletion of the 2b gene from CMV prevented e...

Recent studies have documented effects of plant viruses on host plants that appear to enhance transmission by insect vectors. But, almost no empirical work has explored the implications of such apparent manipulation for interactions among co-infecting pathogens. We examined single and mixed infections of two potyviruses, watermelon mosaic virus (WMV) and zucchini yellow mosaic virus (ZYMV), tha...

We compared some fitness components of the wild squash species Cucurbita pepo spp. ovifera var. texana (C. texana) and three generations of hybrids (F1, BC1, and BC2) between C. texana and commercial transgenic squash CZW-3 over three consecutive years under field conditions of low (LDP) and high disease pressure (HDP) by Cucumber mosaic virus (CMV), Zucchini yellow mosaic virus (ZYMV) and Wate...
