| severe outbreaks of tomato yellow leaf curl sardinia virus in calabria, southern italy. | during the winter 2003--2004 a serious disease was observed in protected tomato crops in castrovillari, reggio calabria province, southern italy. symptoms consisted in marginal leaf yellowing, leaf curling, plant stunting, flower abortion. the disease was detected in a group of greenhouses (about 10ha) where several tomato cultivars were grown hydroponically. the highest incidence of infection (60-100%) was observed in tomatoes grafted on beaufort drs tomato rootstock. since the symptoms were si ... | 2004 | 15756842 |
| integrated management of tylcv/tylcsv on greenhouse hydroponic tomatoes in southern italy. | tomato yellow leaf curl (tylc) caused by tomato yellow leaf curl virus (tylcv) and tomato yellow leaf curl sardinia virus (tylcsv), vectored by the whitefly bemisia tabaci, is a major disease of tomato in sardinia and sicily, and is becoming a serious threat in southern italy too. tylcsv was first reported in calabria region in 1991, but apparently it was an occasional outbreak, and b. tabaci was not detected. later, during the 2003-2004 winter, a serious epidemic was observed in protected tomat ... | 2006 | 17390886 |
| two new natural begomovirus recombinants associated with the tomato yellow leaf curl disease co-exist with parental viruses in tomato epidemics in italy. | two tomato geminivirus species co-exist in protected crops in sicily, tomato yellow leaf curl sardinia virus (tylcsv, found in 1989) and tomato yellow leaf curl virus (tylcv, found in 2002), and mixed infections have been detected. in a field survey conducted in 2004, the viral intergenic region (ir) was amplified from infected plants, and molecules apparently hybrid between the two species were found, but only in plants where one or both parental species were also present. two of these hybrids, ... | 2009 | 19463717 |
| severe outbreak of tomato yellow leaf curl sardinia virus on pepper in southern italy. | during summer and autumn 2008 a severe outbreak of pepper leaf curl disease (plcd) was observed in pepper crops under plastic tunnels in the ionic coast of basilicata region. its incidence reached, in some cases, values close to 50%. the beginning of infections was recorded along the perimeter of the tunnels, where it reached a percentage of almost 100%. the infection then progressively spread towards the central areas of the greenhouses. large populations of whiteflies, identificated as bemisia ... | 2009 | 20222578 |
| the complete nucleotide sequence of an isolate of tomato yellow leaf curl sardinia virus found in sicily. | partial sequences of tomato yellow leaf curl sardinia virus (tylcsv) derived from tomato samples collected in sicily in 1999, 2002 and 2004 indicated the presence of a tylcsv different from the one previously described as the sic strain. here, we report a complete dna sequence that is classified as belonging to the tylcsv type strain (sar strain), confirming the co-existence in sicily of virus populations of both strains. moreover, comparisons between this new sequence and those of the two recom ... | 2010 | 20665057 |
