PROTECTION BETWEEN STRAINS OF Papaya ringspot virus - TYPE W IN ZUCCHINI SQUASH INVOLVES COMPETITION FOR VIRAL REPLICATION SITES

A mild strain of Papaya ringspot virus type W (PRSV-W), named PRSV-W-1, has proved to be very effective in the control of the disease in zucchini squash plants under greenhouse and field conditions. The aim of this work was to obtain additional information on the protection mechanism between PRSV-W-1 and a severe homologous strain (PRSV-W-C) in Cucurbita pepo L. cv. Caserta. Protective inoculat...

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...

Control of papaya ringspot virus in papaya: a case study.

The papaya crop is severely affected by papaya ringspot virus (PSRV) worldwide. This review focuses on efforts to control the destructiveness of the disease caused by PSRV in Hawaii, starting from the use of cross protection to parasite-derived resistance with transgenic papaya expressing the PSRV coat protein gene. A chronology of the research effort is given and related to the development of ...

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...
