Watermelonleafcurl, also known as squashleafcurl or watermeloncurly mottle, is a viral disease that is spread from plant to plant by the saliva and piercing mouthparts of the insect vectors whiteflies. » Squashleafcurl virus can cause severe yield losses on squash and watermelon. » Disease severity is highly correlated with the presence and activity of the sweetpotato and silverleaf whiteflies. Squashleafcurl virus (SLCV) and Watermelon chlorotic stunt virus (WmCSV) are cucurbit-infecting bipartite begomoviruses. Both viruses are found in the eastern Mediterranean basin but the effects of dual infection of both viruses on melon (Cucumis melo L.) have not been described. Amplification and cloning of possible full-length genomes using abutting primers designed from these contigs showed the presence of the begomovirus squashleafcurl virus (SLCV) and watermelon chlorotic stunt virus (WCSV) in 25 cactus plants. Common Causes of CurlingWatermelonLeaves. Watering irregularities frequently cause leafcurling.Viruses like SquashLeafCurl Virus or Cucumber Mosaic Virus interfere with normal growth, leading to crumpled, distorted foliage, yellow mottling, or stunted new growth. Citation2011). The SLC disease can be caused by different ssDNA bipartite begomoviruses (Family Geminiviridae), including cucurbit leafcurl virus (CLCuV) and watermeloncurly mottle virus (WCMoV) and squashleafcurl virus (SLCuV) (Brown et al. Brown JK, NELSON MERRITTR. Characterisation of watermeloncurly mottle virus, a geminivirus distinct from squashleafcurl virus. Annals of Applied Biology. Squashleafcurl virus (SqLCV) was isolated from squash plants cultivated in Fayoum Governorate. Field inspection of squashleafcurl viral disease was determined according to visual symptoms. First report of squashleafcurl geminivirus in Texas (US). Squashleafcurl geminivirus (EU Annex I/A1) has been detected for the first time in Texas (US) in autumn 1993 onwatermelon plants (Citrullus lanatus). Sequencing results were analyzed using BLAST and revealed the presence of three different bipartite begomoviruses which include Squashleafcurl virus (SqLCV) isolated from squash and cucmber, Watermelon chlorotic stunt virus (WmCSV) and Tomato leafcurl Palampur virus... Evidence that watermelonleafcurl disease in Pakistan is associated with Tomato leafcurl virus-India, a bipartite begomovirus. Plant Disease, 84, 102.Molecular characterization of squashleafcurl Yunnan virus, a new begomovirus and evidence for recombination.
