The present study reports the complete genome of a novel monopartite begomovirus, named tentatively as "Citharexylum leaf curl virus" (CitLCuV), associated with leaf curl disease of Citharexylum spinosum in India. CitLCuV genome (2767 nucleotide) contained the typical genome organization of Old World begomoviruses and shared the maximum nucleotide sequence identity of 89.7% with a papaya leaf crumple virus (PaLCrV) isolate. In addition, two small non-canonical open reading frames (C5 and C6) were determined in the complementary strand of CitLCuV genome. Phylogenetic analysis revealed the relatedness of CitLCuV to PaLCrV and rose leaf curl virus. Recombination analysis detected a possible recombination event in CitLCuV genome. Based on begomovirus species demarcation criteria, CitLCuV can be regarded as a novel begomoviral species.

The begomoviral V2 protein is known to be multifunctional, including its interaction with and inhibition of CYP1, a papain-like cysteine protease (PLCP). However, the effect of this interaction on viral pathogenicity remains unclear. Cotton leaf curl Multan virus (CLCuMuV), a typical monopartite begomovirus associated with a betasatellite, is one of the main pathogens responsible for cotton leaf curl disease.

Cotton leaf curl disease (CLCuD) is a major constraint for production of cotton (Gossypium sp.) in Northwest India. CLCuD is caused by a monopartite, circular ssDNA virus belonging to the genus Begomovirus in association with betasatellites and alphasatellites, and ttransmitted by a whitefly vector (Bemisia tabaci).

Background: Tomato yellow leaf curl virus (TYLCV), tomato mosaic virus (ToMV), and Fusarium wilt are three of tomatoes' most important viral and fungal diseases.
Methods And Results: In this study, the application of molecular markers associated with tomato yellow leaf curl virus resistance gene (Ty1), tomato mosaic virus resistance gene (Tm2), and Fusarium wilt resistance gene (I-1) (linked marker) were evaluated. In order to optimize and use SNP markers (by HRM diagnostic method) and SCAR markers, segregating populations of tomatoes were produced by self-pollination of commercial hybrid cultivars.

Two phylogenetically unrelated viruses transmitted by different insect vectors, tomato spotted wilt virus (TSWV) and tomato yellow leaf curl virus (TYLCV), are major threats to tomato and other vegetable production. Although co-infections of TSWV and TYLCV on the same host plant have been reported on numerous occasions, there is still lack of research attempting to elucidate the mechanisms underlying the relationship between two viruses when they coexist in the same tomato or other plants. After assessing the effect of four TSWV-coded proteins on suppressing TYLCV in TSWV N transgenic Nicotiana benthamiana seedlings, the TSWV N protein proved to be effective in reducing TYLCV quantity and viral symptoms.
