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. VIROSES EM VIDEIRAS: IMPACTO ECONÔMICO E RECENTES AVANÇOS NA PROSPECÇÃO DE VÍRUS E MANEJO DAS DOENÇAS DE ORIGEM VIRAL RESUMO-A videira (Vitis spp.) é propagada vegetativamente e considerada uma das principais culturas frutíferas por sua importância socioeconômica mundial. -
Vector Capability of Xiphinema Americanum Sensu Lato in California 1
Journal of Nematology 21(4):517-523. 1989. © The Society of Nematologists 1989. Vector Capability of Xiphinema americanum sensu lato in California 1 JOHN A. GRIESBACH 2 AND ARMAND R. MAGGENTI s Abstract: Seven field populations of Xiphineraa americanum sensu lato from California's major agronomic areas were tested for their ability to transmit two nepoviruses, including the prune brownline, peach yellow bud, and grapevine yellow vein strains of" tomato ringspot virus and the bud blight strain of tobacco ringspot virus. Two field populations transmitted all isolates, one population transmitted all tomato ringspot virus isolates but failed to transmit bud blight strain of tobacco ringspot virus, and the remaining four populations failed to transmit any virus. Only one population, which transmitted all isolates, bad been associated with field spread of a nepovirus. As two California populations of Xiphinema americanum sensu lato were shown to have the ability to vector two different nepoviruses, a nematode taxonomy based on a parsimony of virus-vector re- lationship is not practical for these populations. Because two California populations ofX. americanum were able to vector tobacco ringspot virus, commonly vectored by X. americanum in the eastern United States, these western populations cannot be differentiated from eastern populations by vector capability tests using tobacco ringspot virus. Key words: dagger nematode, tobacco ringspot virus, tomato ringspot virus, nepovirus, Xiphinema americanum, Xiphinema californicum.

M. C ram4 Abstract: We describe and illustrate anew needle nematode, Longidorus americanum n. sp., associated with patches of severely stunted and chlorotic loblolly pine, ( Pinus taeda L.) seedlings in seedbeds at the Flint River Nursery (Byromville, GA). It is characterized by having females with abody length of 5.4–9.0 mm; lip region slightly swollen, anteriorly flattened, giving the anterior end atruncate appearance; long odontostyle (124–165 µm); vulva at 44%–52% of body length; and tail conoid, bluntly rounded to almost hemispherical. Males are rare but present, and in general shorter than females. The new species is morphologically similar to L. biformis, L. paravineacola, L. saginus, and L. tarjani but differs from these species either by the body, odontostyle and total stylet length, or by head and tail shape. Sequence data from the D2–D3 region of the 28S rDNA distinguishes this new species from other Longidorus species. Phylogenetic relationships of Longidorus americanum n. sp. with other longidorids based on analysis of this DNA fragment are presented. Additional information regarding the distribution of this species within the region is required.
