| chinese squash leaf curl virus: a new whitefly-transmitted geminivirus. | coat protein (cp) gene of the chinese squash leaf curl virus (sqlcv-c) was amplified through pcr, cloned and completely sequenced. based on the comparisons at the levels of both cp gene nucleotide and cp-deduced amino acid sequences with other geminiviruses, sqlcv-c is confirmed to be distinct from the american squash leaf curl virus (sqlcv-e). it is a new geminivirus transmitted by whitefly bemisia tabaci, which infects dicotyledonous plants and is more closely related to the indian cassava mos ... | 1995 | 7755872 |
| [cloning and sequencing of chinese squash leaf curl virus]. | sequence analysis of virus isolation dna of squash leaf curl disease shows that squash leaf curl virus (slch-chi) contains 2741nt, which encode six open reading frames (orfs). two of them are on virus sense strand: av1 (256aa) and av2 (140aa). av1 encode coat protein. the other of orfs are on complementary sense strand: ac1 (replicase gene, 243aa), ac2 (transactivtor, 134aa), ac3 (136aa) and ac4 (172aa). the virus belongs to one number of begomoviruses from old world. | 2001 | 12549185 |
| the complete nucleotide sequence of two distinct geminiviruses infecting cucurbits in vietnam. | we have characterised two distinct geminiviruses that infect cucurbit cultivars in vietnam. the genomes of both viruses consisted of two circular ssdna components (dna-a and dna-b), with a genome arrangement and coding sequence typical of viruses in the begomovirus genus in the family geminiviridae. the sequence of dna-a of one of the viruses was approximately 97% similar to squash leaf curl virus-china (slcv-ch), for which a dna-b has yet to be identified. we have named this virus squash leaf c ... | 2003 | 12898329 |
| biological and molecular characterization of a begomovirus associated with yellow mosaic vein mosaic disease of pumpkin from northern india. | the biological and molecular properties of squash leaf curl china virus from varanasi, india (slccnv-in[in:var:pum]) were characterized. slccnv-in[in:var:pum] could be transmitted by grafting and through whitefly transmission. the complete dna-a and dna-b components were amplified through pcr using specific dna-a and dna-b primers. the dna-a of the isolate was comprised of 2,738 nucleotides, encoding typical six open reading frames, and dna-b of 2,704 nucleotides, encoding two orfs. genome organ ... | 2009 | 19705268 |
| complete nucleotide sequences of a distinct bipartite begomovirus, bitter gourd yellow vein virus, infecting momordica charantia. | momordica charantia (cucurbitaceae), a vegetable crop commonly cultivated throughout pakistan, and begomoviruses, a serious threat to crop plants, are natives of tropical and subtropical regions of the world. leaf samples of m. charantia with yellow vein symptoms typical of begomovirus infections and samples from apparently healthy plants were collected from areas around lahore in 2004. full-length clones of a bipartite begomovirus were isolated from symptomatic samples. the complete nucleotide ... | 2010 | 20924621 |
| molecular characterization of tomato leaf curl palampur virus and pepper leaf curl betasatellite naturally infecting pumpkin (cucurbita moschata) in india. | pumpkin cultivation in india is affected by severe incidence of a yellow vein mosaic disease. tomato leaf curl new delhi virus and squash leaf curl china virus are known to be associated with this disease in india. we were able to identify a third begomovirus-tomato leaf curl palampur virus (tolcpmv), from pumpkin showing typical symptoms of the disease at varanasi based on the sequence of complete dna-a genome of the virus. the complete dna-a sequence of the virus shared more than 99% sequence ... | 2011 | 23637491 |
| chlorotic curly stunt: a severe begomovirus disease of bottle gourd in northern india. | bottle gourd (lagenaria siceraria) an important vegetable crop in india was observed to be affected by a chlorotic curly stunt disease (ccsd) during 2003-2006 in the vegetable growing areas of delhi and adjoining state of haryana. the affected plants are severely stunted and bear very small chlorotic and mildly curled leaves. incidence of the disease varied from 4.7 to 36%. the disease could be easily transmitted by whitefly, bemisia tabaci but not by sap. the causal virus was found to be a bego ... | 2010 | 23637479 |
| development and application of triple antibody sandwich enzyme-linked immunosorbent assays for begomovirus detection using monoclonal antibodies against tomato yellow leaf curl thailand virus. | tomato yellow leaf curl thailand virus, tylcthv, is a begomovirus that causes severe losses of tomato crops in thailand as well as several countries in southeast and east asia. the development of monoclonal antibodies (mabs) and serological methods for detecting tylcthv is essential for epidemiological studies and screening for virus-resistant cultivars. | 2017 | 28558726 |
| first complete squash leaf curl china virus genomic segment dna-a sequence from east timor. | we present here the first complete squash leaf curl china virus (slccv) genomic segment dna-a sequence from east timor. it was isolated from a pumpkin plant. when compared with 15 complete slccv dna-a genome sequences from other world regions, it most resembled the malaysian isolate mc1 sequence. | 2017 | 28619789 |
