آفتابگردان (helianthus annuus l.) یکی از گیاهان دانه روغنی مهم در ایران و بسیاری از کشور ها می باشد. ویروس ها ازجمله بیمار گر هایی هستند که باعث ایجاد خسارت در این محصول می شوند. به منظور بررسی میزان آلودگی پوتی ویروس ها و سایر ویروس های خسارت زننده به آفتابگردان در مزارع استان اصفهان نمونه برداری هایی طی سه سال 89 تا 91 انجام شد. در طی این مدت 265 نمونه ی برگی با علایم ویروسی و بدون علایم ویرو...
Potato virus Y biberde enfeksiyon oluşturan en yaygın virüslerden bir tanesidir. Bu çalışmada, 23 biber çeşidi ve 30 ıslah hattının PVY-0 PVY-1 patotiplerine karşı reaksiyonları belirlenmiş pvr2 lokusundaki allel genleri mekanik inokulasyon moleküler yöntemler ile belirlenmeye çalışılmıştır. Her çeşit hatta ait dörder bitki, patotipleri ayrı inokule edilmiştir. İnokule edilen bitkiler, virüs si...
پژوهش حاضر، اثر سالیسیلیک اسید بر میزان کلروفیل a و سطح برگ دو رقم سیبزمینی (آگریا و مارفونا) در شرایط گلخانهای به منظور کاهش بیماریزایی ویروس Y سیبزمینی (PVY) انجام شد. گیاهچههای سیبزمینی عاری از عوامل بیماریزا تکثیر شده و گیاهچههای رشد کرده به گلدانهایی با خاک مناسب و استریل منتقل شدند. گیاهچهها با غلظتهای صفر (شاهد)، 2/0، 5/0، 1 و 2 میلیمولار سالیسیلیک اسید تیمار شدند. عصاره فعال...
Potato virus Y (PVY) is an important plant virus and causes great losses every year. Viral infection often leads to abnormal chloroplasts. The first step of chloroplast division is the formation of FtsZ ring (Z-ring), and the placement of Z-ring is coordinated by the Min system in both bacteria and plants. In our lab, the helper-component proteinase (HC-Pro) of PVY was previously found to inter...
RESUMEN Potato virus Y (PVY) is one of the most severe viruses affecting the production of potato (Solanum tuberosum) in the world. This study presents a detailed molecular analysis using nextgeneration sequencing (NGS), IC-RT-qPCR and RT-PCR on the PVY isolates infecting seed-tubers and foliage of potato plants cv. Diacol-Capiro in La Union (Antioquia, Colombia). Analysis of incidence by IC-RT...
To investigate the dynamics of the potato-Potato virus Y (PVY) compatible interaction in relation to salicylic acid-controlled pathways we performed experiments using non-transgenic potato cv. Désirée, transgenic NahG-Désirée, cv. Igor and PVY(NTN), the most aggressive strain of PVY. The importance of salicylic acid in viral multiplication and symptom development was confirmed by pronounced sym...
The purpose of the study was to investigate the role of salicylic acid (SA) signalling in Ny-1-mediated hypersensitive resistance (HR) of potato (Solanum tuberosum L.) to Potato virus Y (PVY). The responses of the Ny-1 allele in the Rywal potato cultivar and transgenic NahG-Rywal potato plants that do not accumulate SA were characterized at the cytological, biochemical, transcriptome, and prote...
UNLABELLED The structural pattern of infectivity matrices, which contains infection data resulting from inoculations of a set of hosts by a set of parasites, is a key parameter for our understanding of biological interactions and their evolution. This pattern determines the evolution of parasite pathogenicity and host resistance, the spatiotemporal distribution of host and parasite genotypes, a...
