Khatun MF, Hwang HS, Shim JK, Kil EJ, Lee S, Lee KY. Identification of begomoviruses from different cryptic species of Bemisia tabaci in Bangladesh. Microb Pathog 2020; 142:104069. [PMID: 32061918 DOI: 10.1016/j.micpath.2020.104069] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2019] [Revised: 01/20/2020] [Accepted: 02/12/2020] [Indexed: 11/21/2022]
Abstract
Bemisia tabaci is a global species complex consisting of at least 40 cryptic species. It is also a vector for at least 100 species of begomovirus, many of which cause severe crop damage. The relationship between begomoviruses and cryptic species of the B. tabaci species complex, however, remains unclear. Our previous study [13] was identified four cryptic species (Asia I, Asia II 1, Asia II 5, and Asia II 10) of B. tabaci from Bangladesh. Using those 110 whitefly samples, vector-based PCR analysis identified 8 different begomovirus species: BYVMV, BGYVV, OELCV, SLCCV, SLCV, TbCSV, ToLCBV, and ToLCNDV. The overall rate of virus infection was 26.4%, and BYVMV and ToLCNDV were the most frequently detected in the B. tabaci vector. Virus infection rates for Asia I, Asia II 1, Asia II 5, and Asia II 10 were 22.4% (15/67), 35% (7/20), 27.3% (6/22), and 100% (1/1), respectively. Each cryptic species infected multiple virus species, but SLCCV, TbCSV, and BGYVV were each only detected in, Asia I, Asia II 1, and Asia II 5, respectively. This study demonstrates the geographic distribution of various begomoviruses in Bangladesh and their relationships with cryptic species of B. tabaci.

Abstract
The spread of cotton leaf curl disease in China, India and Pakistan is a recent phenomenon. Analysis of available sequence data determined that there is a substantial diversity of cotton-infecting geminiviruses in Pakistan. Phylogenetic analyses indicated that recombination between two major groups of viruses, cotton leaf curl Multan virus (CLCuMuV) and cotton leaf curl Kokhran virus (CLCuKoV), led to the emergence of several new viruses. Recombination detection programs and phylogenetic analyses showed that CLCuMuV and CLCuKoV are highly recombinant viruses. Indeed, CLCuKoV appeared to be a major donor virus for the coat protein (CP) gene, while CLCuMuV donated the Rep gene in the majority of recombination events. Using recombination free nucleotide datasets the substitution rates for CP and Rep genes were determined. We inferred similar nucleotide substitution rates for the CLCuMuV-Rep gene (4.96X10-4) and CLCuKoV-CP gene (2.706X10-4), whereas relatively higher substitution rates were observed for CLCuMuV-CP and CLCuKoV-Rep genes. The combination of sequences with equal and relatively low substitution rates, seemed to result in the emergence of viral isolates that caused epidemics in Pakistan and India. Our findings also suggest that CLCuMuV is spreading at an alarming rate, which can potentially be a threat to cotton production in the Indian subcontinent.
