Abstract
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.
期刊介绍：
Viruses are convenient models for the elucidation of life processes. The study of viruses is again on the cutting edge of biological sciences: systems biology, genomics, proteomics, metagenomics, using the newest most powerful tools.
Huge amounts of new details on virus interactions with the cell, other pathogens and the hosts – animal (including human), insect, fungal, plant, bacterial, and archaeal - and their role in infection and disease are forthcoming in perplexing details requiring analysis and comments.
Virus Genes is dedicated to the publication of studies on the structure and function of viruses and their genes, the molecular and systems interactions with the host and all applications derived thereof, providing a forum for the analysis of data and discussion of its implications, and the development of new hypotheses.
