Cotton is under the constant threat of leaf curl virus, which is a major constraint for successful production of cotton in the Pakistan. A total of 3338 cotton genotypes belonging to different research stations were screened, but none were found to be resistant against the Burewala strain of cotton leaf curl virus (CLCuV). We explored the possibility of transferring virus-resistant genes f...

The genome of the tomato yellow leaf curl virus (TYLCV), a Bemisia tabaci-transmitted geminivirus, was cloned. All clones obtained were of one genomic molecule, analogous to DNA A of African cassava mosaic virus. Nucleotide sequence analysis of the TYLCV genome showed that it comprises 2787 nucleotides, encoding six open reading frames, two on the virion strand and four on the complementary str...

Begomoviruses are transmitted by cryptic species of the whitefly Bemisia tabaci complex, often in a species-specific manner. Papaya leaf curl China virus (PaLCuCNV) has been recorded to infect several crops including papaya, tomato and tobacco in China. To help assess the risks of spread of this virus, we compared the acquisition, retention and transmission of PaLCuCNV among four species of whi...

The important cash crop of Chilli’s (Capsicum annum L) production and yield is hampered by Chilli Leaf Curl Virus Disease (CLCVD) in Sri Lanka. To manage CLCVD several insecticides were promised against the vectors CLCV. Indiscriminate use created unwanted human health hazards. current trends plant pathology intend to boost immunity host increase resistance pathogens. Therefore, this study was ...

BACKGROUND The whitefly Bemisia tabaci (Genn.) causes dramatic damage to plants by transmitting yield-limiting virus diseases. Previous studies proved that the tomato breeding line ABL 14-8 was resistant to B. tabaci, the vector of tomato yellow leaf curl disease (TYLCD). This resistance is based on the presence of type IV glandular trichomes and acylsucrose production. These trichomes deter se...

In the present climate change scenario, controlling plant disease through exploitation of host plant resistance could contribute toward the sustainable crop production and global food security. In this respect, the identification of new sources of resistance and utilization of genetic diversity within the species may help in the generation of cultivars with improved disease resistance. Begomovi...
