Grapevine Virus Diseases: Economic Impact and Current Advances in Viral Prospection and Management1
1/22 ISSN 0100-2945 http://dx.doi.org/10.1590/0100-29452017411 GRAPEVINE VIRUS DISEASES: ECONOMIC IMPACT AND CURRENT ADVANCES IN VIRAL PROSPECTION AND MANAGEMENT1 MARCOS FERNANDO BASSO2, THOR VINÍCIUS MArtins FAJARDO3, PASQUALE SALDARELLI4 ABSTRACT-Grapevine (Vitis spp.) is a major vegetative propagated fruit crop with high socioeconomic importance worldwide. It is susceptible to several graft-transmitted agents that cause several diseases and substantial crop losses, reducing fruit quality and plant vigor, and shorten the longevity of vines. The vegetative propagation and frequent exchanges of propagative material among countries contribute to spread these pathogens, favoring the emergence of complex diseases. Its perennial life cycle further accelerates the mixing and introduction of several viral agents into a single plant. Currently, approximately 65 viruses belonging to different families have been reported infecting grapevines, but not all cause economically relevant diseases. The grapevine leafroll, rugose wood complex, leaf degeneration and fleck diseases are the four main disorders having worldwide economic importance. In addition, new viral species and strains have been identified and associated with economically important constraints to grape production. In Brazilian vineyards, eighteen viruses, three viroids and two virus-like diseases had already their occurrence reported and were molecularly characterized. Here, we review the current knowledge of these viruses, report advances in their diagnosis and prospection of new species, and give indications about the management of the associated grapevine diseases. Index terms: Vegetative propagation, plant viruses, crop losses, berry quality, next-generation sequencing.

Some of these pathogens cause severe crop losses and often reduce the productive life of the orchards. Detection and characterization of these agents in fruit trees is challenging, however, during the last years, the wide application of high-throughput sequencing (HTS) technologies has significantly facilitated this task. In this review, we present recent advances in the discovery, detection, and characterization of fruit tree viruses and virus-like agents accomplished by HTS approaches. -

Order code: CPE 109. Abstract The International Working Group Meeting on groundnut viruses in Africa reviewed progress made on the detection, identification, characterization, and management of groundnut viruses in Africa, with special emphasis on rosette and clump viruses. Country representatives summarized the status of research on groundnut viruses in their countries. In order to accomplish integrated management of rosette and clump virus diseases, it was agreed that consolidated efforts should be made to understand their epidemiology. Among the important aspects discussed were the provision of diagnostic aids and training in the identifi cation and detection of viruses for the national agricultural research systems in Africa, and strengthening of laboratory facilities. Scientists from Burkina Faso, Kenya, Malawi, Nigeria, South Africa, and Zimbabwe, and from Bel gium, Germany, India, UK, and USA attended the meeting, which was the first gathering of so many plant virologists in -

The ORF3 protein of the plant virus, groundnut rosette Nevertheless, they accumulate and spread efficiently within the virus (an umbravirus), has been shown to cycle through the infected plant; their lack of a CP is compensated for by the ORF3 nucleus, passing through Cajal bodies to the nucleolus and then protein. This protein fulfils umbraviral functions that are normally exiting back into the cytoplasm. This journey is absolutely required provided by the CPs of other plant viruses, such as long-distance for the formation of viral ribonucleoprotein particles (RNPs) that, movement of viral RNA through the phloem (17, 18). -

Previously, only limited reports have shown the genetic variation of BBWV2. Meanwhile, the detailed evolution- ary changes, synonymous codon usage bias and host adaptation of this virus are largely unclear. Here, we performed comprehensive analyses of the phylodynamics, reassortment, composition bias and codon usage pattern of BBWV2 using forty-two complete genome sequences of BBWV-2 isolates together with two other full-length RNA1 sequences and six full-length RNA2 sequences. Both recombination and reassortment had a significant influence on the genomic evolution of BBWV2. Through phylogenetic analysis we detected three and four lineages based on the ORF1 and ORF2 nonrecombinant sequences, respectively. The evolutionary rates of the two BBWV2 ORF coding sequences were 8.895 × 10−4 and 4.560 × 10−4 subs/site/year, respectively. We found a relatively conserved and stable genomic composition with a lower codon usage choice in the two BBWV2 protein coding sequences. -
