Abstract

Cucurbitaceous crops are a key group of vegetables widely cultivated in India. Characterized yellowing symptoms along with interveinal chlorosis, mottling and downward curling were observed in ridge gourd, snake gourd, and bottle gourd along with the presence of whiteflies (Bemisia tabaci). To investigate the infecting virus, RT-PCR assays followed by sequencing and Transmission Electron Microscopy (TEM) analysis were performed. Sanger sequencing, nucleotide sequence analysis, and TEM imaging confirmed the association of cucurbit yellow stunting disorder virus (CYSDV), genus Crinivirus within the family Closteroviridae. This study reports the natural occurrence of CYSDV in ridge gourd, snake gourd, and bottle gourd for the first time in India.

首次报告葫芦黄化病病毒在印度主要瓜类上引起黄化病

葫芦科作物是印度广泛种植的一类重要蔬菜。在脊瓠瓜、蛇瓠瓜和瓶瓠瓜上观察到了特征性的黄化症状以及叶脉间萎黄、斑驳和向下卷曲，同时还发现了粉虱（Bemisia tabaci）。为了研究感染病毒，进行了 RT-PCR 检测，然后进行了测序和透射电子显微镜（TEM）分析。桑格测序、核苷酸序列分析和透射电子显微镜成像证实了葫芦黄矮病病毒（CYSDV）与瘤胃病毒科瘤胃病毒属（Crinivirus）的关系。本研究首次报道了 CYSDV 在印度脊瓜、蛇瓜和瓶瓜中的自然发生。

期刊介绍： The Editors of Crop Protection especially welcome papers describing an interdisciplinary approach showing how different control strategies can be integrated into practical pest management programs, covering high and low input agricultural systems worldwide. Crop Protection particularly emphasizes the practical aspects of control in the field and for protected crops, and includes work which may lead in the near future to more effective control. The journal does not duplicate the many existing excellent biological science journals, which deal mainly with the more fundamental aspects of plant pathology, applied zoology and weed science. Crop Protection covers all practical aspects of pest, disease and weed control, including the following topics: -Abiotic damage- Agronomic control methods- Assessment of pest and disease damage- Molecular methods for the detection and assessment of pests and diseases- Biological control- Biorational pesticides- Control of animal pests of world crops- Control of diseases of crop plants caused by microorganisms- Control of weeds and integrated management- Economic considerations- Effects of plant growth regulators- Environmental benefits of reduced pesticide use- Environmental effects of pesticides- Epidemiology of pests and diseases in relation to control- GM Crops, and genetic engineering applications- Importance and control of postharvest crop losses- Integrated control- Interrelationships and compatibility among different control strategies- Invasive species as they relate to implications for crop protection- Pesticide application methods- Pest management- Phytobiomes for pest and disease control- Resistance management- Sampling and monitoring schemes for diseases, nematodes, pests and weeds.
