“…R. crispus is natural hosts of whiteflies and thrips (Groves et al, 2002;Lee et al, 2008), Rumex spp. showed a germination rate of 63-90% during a period of 2-7 years (Palai, 2010;Polston et al, 2009). It is necessary to ensure that the roots of perennial weeds are removed completely during the agricultural cultivation process by translocating systemic herbicides such as glyphosate and auxinic herbicides, which could benefit perennial weed control (Davies and Peoples, 2003;Hess, 2018;Steinmann et al, 2012).…”

Tomato yellow leaf curl virus (TYLCV) and tomato spotted wilt virus (TSWV) are well-known examples of the begomovirus and orthotospovirus genera, respectively. These viruses cause significant economic damage to tomato crops worldwide. Weeds play an important role in the ongoing presence and spread of several plant viruses, such as TYLCV and TSWV, and are recognized as reservoirs for these infections. This work applies a comprehensive approach, encompassing field surveys and molecular techniques, to acquire an in-depth understanding of the interactions between viruses and their weed hosts. A total of 60 tomato samples exhibiting typical symptoms of TYLCV and TSWV were collected from a tomato greenhouse farm in Nonsan, South Korea. In addition, 130 samples of 16 different weed species in the immediate surroundings of the greenhouse were collected for viral detection. PCR and reverse transcription-PCR methodologies and specific primers for TYLCV and TSWV were used, which showed that 15 tomato samples were coinfected by both viruses. Interestingly, both viruses were also detected in perennial weeds, such as Rumex crispus, which highlights their function as viral reservoirs. Our study provides significant insights into the co-occurrence of TYLCV and TSWV in weed reservoirs, and their subsequent transmission under tomato greenhouse conditions. This project builds long-term strategies for integrated pest management to prevent and manage simultaneous virus outbreaks, known as twindemics, in agricultural systems.

“…Most of wild tomato species such as S. chilense, S. habrochaites (formerly L. hirsutum), S. peruvianum, and S. pimpinellifolium were symptomless carriers and could be used in breeding programs for TYLCV resistance (Zakay et al 1991). Beside tomato, other plant species in several botanical families were found potentially host plant species of this virus (Mansour and Al-Musa 1992;Kegler 1994;Cohen and Antignus 1994;Nakhla and Maxwell 1998;Polston et al 2009;Salati et al 2002). In many cases the disease caused losses in yields that could be reached up to 100% (Polston et al 1999).…”

Tomato, considered one of most important and popular crop, was infected by Tomato Yellow Leaf Curl Virus (TYLCV) which causes significant yields loss. Biological and molecular tools were used to evaluate the TYLCV incidence on tomatoes grown under commercial conditions. A total number of 72 tomato plants from each eight different tomato cultivars commercially planted in Palestine were tested for their virus infection which occurred naturally. The virus incidence was reported biologically based on visual inspections for the disease symptoms and molecularly by PCR tests, in two growing season periods: Summer (2006) and spring (2007). As a result, no cultivars were found “immune” to virus infection. However, fundamental differences in symptoms development and severity had been discovered. This study, which was carried out for the first time in Palestine, showed that some cultivars such as “3060” could be targeted as promising virus-tolerant ones. The sensitivity of molecular methods over bioassays was evaluated, and combined methods were suggested for any cultivars resistance assessments. Besides, research results revealed that the experimental conditions in Spring were not in favor of the virus spread, as the main virus vector (Bemisia tabaci) population number would be lower in the Summer season; thus the Spring season is seen as the best one for farmers to escape from TYLCV infections. تعتبر البندورة واحدة من المحاصيل المهمة والشعبية، ولكنها تصاب بفيروس تجعد واصفرار اوراق البندورة (TYLCV) مما يسبب خسارة كبيرة في الانتاج. تم استخدام الأدوات البيولوجية والجزيئية لتقييم الإصابة على البندورة والتي نمت في الظروف التجارية. تم اختبار 72 من نبات الطماطم لكل صنف من الأصناف الثمانية للطماطم المختلفة والمستعملة تجاريا في فلسطين، وذلك بفحص اصابتها بالفيروس المنتقل اليها بشكل طبيعي. حيث تم ثبوت وقوع الاصابة الفيروسية بيولوجيا عن طريق عمليات التفتيش البصرية لأعراض المرض، وجزيئيا عن طريق اختبارات تضاعف الحمض النووي (PCR)، وذلك في موسمين: صيف (2006) وربيع (2007). وكانت النتيجة لذلك انه لا توجد "مناعة" لعدوى الفيروس لأي من الأصناف المختبرة. ومع ذلك، فقد كشفت الدراسة، والتي تجرى للمرة الأولى في فلسطين، اختلافات جوهرية في تطور المرض وشدة الاصابة. حيث أظهرت النتائج انه يمكن استهداف بعض الأصناف الواعدة مثل "3060" لكونها الاكثر تحملا للفيروس. تم كذلك تقييم حساسية الاختبارات الجزيئية مقارنة بمثيلاتها البيولوجية، واقتراح استعمال الاختبارين معا في تقييم أي أصناف مقاومة. اضافة الى ذلك، كشفت النتائج أن الظروف التجريبية في الربيع لم تكن في صالح انتشار الفيروس، حيث أن تعداد ناقلات الفيروس الرئيسة (الذبابة البيضاء) تكون أقل من موسم الصيف، مشيرة الى ان هذا الموسم هو الأفضل للمزارعين للهروب من الاصابة بالفيروس (TYLCV).
