Detection of zucchini yellow mosaic virus by latex flocculation and protein a-coated latex-linked antisera tests.

Study of resistance to cucumber mosaic virus watermelon mosaic virus and zucchini yellow mosaic virus in melon cultivars

Inheritance of resistance to zucchini yellow mosaic virus and watermelon mosaic virus in watermelon.

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...

A Comparison of the Rose-waaler, Latex Fixation, "ra-test," and Bentonite Flocculation Tests.

The bentonite flocculation test of Bozicevich, Bunim, Freund, and Ward (1958), the latex fixation test of Singer and Plotz (1956), and the "RA-test" (a latex reagent for use as a slide test) of Hyland Laboratories have been compared with each other and with a modified Rose-Waaler test, the behaviour of which has been previously extensively investigated. In these tests sera from 2,250 patients w...

شناسایی و تعیین استرین های ویروس موزائیک زرد کدو(zucchini yellow mosaic virus)در استان گلستان

در چند سال گذشته، بیماری های ویروسی از جمله عوامل محدودکننده ی تولید کدوئیان در دنیا بوده اند طوریکه، خسارت و پراکنش ویروس های شته زادی همچون ویروس موزائیک زرد کدوzucchini yellow mosaic virus(zymv) در این میان، قابل ملاحظه بوده است. با عنایت به اینکه شمال ایران بلحاظ شرایط آب و هوایی معتدل، از مراکز عمده تولید کدوئیان بشمار می آید در این بررسی، تعیین و شناسایی استرینهای ویروس فوق الذکر، با نمون...

Nucleotide sequences of the coat protein genes of two Japanese zucchini yellow mosaic virus isolates.

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...
