A New Procedure to Identify Plant RNA Viruses Associated with the Whitefly (Bemisia tabaci) Using Next-Generation Sequencing

Abstract

Salman, M.D. and A.A. Lahuf. 2022. A New Procedure to Identify Plant RNA Viruses Associated with the Whitefly (Bemisia tabaci) Using Next-Generation Sequencing. Arab Journal of Plant Protection, 40(2): 169-174. https://doi.org/10.22268/AJPP-040.2.169174 Next-generation sequencing (NGS) was applied to obtain the transcriptome data of the Iraqi whitefly (Bemisia tabaci) that was analyzed using some specific bioinformatic tools and programs to identify the accompanying plant RNA viruses. Seven different plant viruses were detected: Alfalfa mosaic virus (AMV), Pittosporum cryptic virus-1 (PiCV1), Grapevine leafroll-associated virus (GLRaV), Broad bean wilt virus (BBWV), and Zantedeschia mild mosaic virus (ZaMMV), in addition to Tomato spotted wilt virus (TSWV). The highest quantity of viruses identified were AMV, BBWV, and ZaMMV, respectively through achievement of the highest viral sequence coverages. In this study, we report a new NGS-based procedure, which facilitates prompt and precise the identification and quantification of plant viruses in a pool of B. tabaci insect samples without the necessity for specific primers and application of the conventional PCR technique. The benefit of this method is the quick detection of the potential viruses transmitted by the whitefly, B. tabaci vector that affects countless plant hosts. However, Additional examinations are required to confirm these findings. Keywords: Next generation sequencing, plant RNA viruses; whitefly vector; transcriptome data

“…The remaining data were assembled first using the DeNovo assembly method that produced 65,578 overlapping contigs. The comparison results of these contigs with the data of plant virus's genome sequences [14] (showed a high similarity with many plant viruses belonging to different families. As well as, the overlapping contigs of size 200 bp and above that are similar to plant virus sequences were approved, and less than that, even if they were similar to one of the virus sequences, were ignored.…”

“…The family comprises of nine genera, differentiated based on genome structure, host range and insect vector [12]. Among these, Begomovirus is the largest group, with over 424 species reported so far and are transmitted by different cryptic species of whitefly [13,14]. The classification of Begomoviruses is based on their genome composition, with monopartite viruses possessing a single genome component and the bipartite viruses having two similar-sized components, DNA-A and DNA-B [15].…”

“…In conjunction with bioinformatics, next-generation sequencing (NGS) methods enable concurrently identification of both recognized and unrecognized viruses and mycoviruses in crops. This methodology has been effectively utilized in diverse research endeavors and has the potential for identifying mycoviral sequences in plant specimens [10,11,12].…”

“…The information in this article comes from academic journals, government documents, and other sources that are open to the general public [6]. The virus is transmitted by the whitefly B. tabaci and is a single-stranded DNA (ssDNA) begomovirus [7,8]. A high prevalence of the virus is often linked with a high incidence of illness [9].…”
