Analyzes of mealybug (Pseudococcus longispinus) virome reveal grapevine viruses diversity
2024
Overview
The long-tailed mealybug,
Pseudococcus longispinus
, is an important insect pest in grapevine growing areas in several countries, including Brazil. Metagenomic analysis of nucleic acids extracted from insect vectors makes it possible to study the diversity of insect viruses in addition to plant pathogenic viruses. In this study, insects (
Ps. longispinus
) were collected, and pooled throughout a plot of virus disease symptomatic vines, cultivated in growing beds, and analyzed by high throughput sequencing (HTS). The complete genome of grapevine leafroll-associated virus 2 and 3 (GLRaV-2 and -3) and a partial sequence of grapevine virus A (GVA) with two complete ORFs (coat protein and RNA-binding protein) were assembled from mealybug extracts and exhibited high nucleotide identities, up to 99%, with previously characterized homologous Brazilian isolates from grapevines. This information was validated by the detection of these viruses in the original symptomatic vines (N=76), from where mealybugs were collected, equivalent to an incidence of 34.2%, 89.5% and 36.8% for GLRaV-2, GLRaV-3 and GVA, respectively. Although one of these viruses is not transmitted by mealybugs (GLRaV-2), prospection of plant viruses infecting grapevine plants by analyzing the metagenome of insects could represent a relevant alternative to improve monitoring of viral diseases aiming at the management and control of viral diseases in vineyards or cultivation fields. This work is the first analysis of the
Ps. longispinus
virome in Brazil focusing on grapevine viruses.
