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.

Transmission of Virus by the Progeny of Crosses Between Xiphinema Diversicaudatum
Transmission of virus by the progeny of crosses between XQhinema diversicaudatüm (Nematoda : Dorylaimoidea) from Italy and Scotland Derek J. F. BROWN Scottish Crop Research Institute, Invergowrie, Dundee, 002 SDA, Scotland. SUMMARY Transmission of the type-British strainsof arabis mosaic (AMV-T) and strawberry latent ringspot viruses (SLRV-T) and a strain of SLRV from Italy (SLRV-Ip) by FI and F2 hybrid Xiphinenza diversicaudatum was examined in the laboratory. The hybrid nematodes were crossbred from populations which readily (Scotland) and only infrequently (Italy) transmitted viruses.The ability of X. diversicaudatum hybrids to transmit viruses was foundto be inherited withthe choice of both maternaland paternal parents affecting the hybrids ability to transmit viruses. It is possible that the genetic influence on the hybrids ability to transmit viruses was cytoplasmically inherited. The principal factor likely to be involved is the ability of X. di ver sic au da tu??^ selectively and specifically to retain virus particles at sites of retention within its feeding apparatus.

Occurrence of Apple mosaic virus (ApMV), Prune dwarf virus (PDV), Prunus necrotic ringspot virus (PNRSV), Apple chlorotic leaf spot virus (ACLSV), and Plum pox virus (PPV) was investigated by RT-PCR and DAS ELISA detection methods. The de- tection rates of both methods were compared. Screening of occurrence of Strawberry latent ringspot virus (SLRSV), Arabis mosaic virus (ArMV), Tomato ringspot virus (ToRSV) and Petunia asteroid mosaic virus (PeAMV) was performed by DAS-ELISA. In total, 38% of the tested trees by RT-PCR were infected at least with one of the analysed viruses. Among those 30.7% were in- fected with PNRSV and 16.4% with PDV, while ApMV, ACLSV and PPV were detected in few samples. The most widespread mixed infection was the combination of PDV+PNRSV. Observed symptoms characteristic for PPV were confirmed with RT-PCR and D strain was detected. Com- parative analyses showed that detection rates by RT-PCR and DAS ELISA in plums depended on the particular virus tested. -
Phylogenetic Position and Generic Limits of Arabidopsis (Brassicaceae)
PHYLOGENETIC POSITION Steve L. O'Kane, Jr.2 and Ihsan A. 3 AND GENERIC LIMITS OF Al-Shehbaz ARABIDOPSIS (BRASSICACEAE) BASED ON SEQUENCES OF NUCLEAR RIBOSOMAL DNA1 ABSTRACT The primary goals of this study were to assess the generic limits and monophyly of Arabidopsis and to investigate its relationships to related taxa in the family Brassicaceae. Sequences of the internal transcribed spacer region (ITS-1 and ITS-2) of nuclear ribosomal DNA, including 5.8S rDNA, were used in maximum parsimony analyses to construct phylogenetic trees. An attempt was made to include all species currently or recently included in Arabidopsis, as well as species suggested to be close relatives. Our ®ndings show that Arabidopsis, as traditionally recognized, is polyphyletic. The genus, as recircumscribed based on our results, (1) now includes species previously placed in Cardaminopsis and Hylandra as well as three species of Arabis and (2) excludes species now placed in Crucihimalaya, Beringia, Olimar- abidopsis, Pseudoarabidopsis, and Ianhedgea. Key words: Arabidopsis, Arabis, Beringia, Brassicaceae, Crucihimalaya, ITS phylogeny, Olimarabidopsis, Pseudoar- abidopsis. Arabidopsis thaliana (L.)

Nematodes are belongs to animal kingdom, they are triploblastic, unsegmented, bilateral symmetrical, pseudocoelomateandhaving well developed reproductive, nervous, excretoryand digestive system where as the circulatory and respiratory systems are absent but govern by the pseudocoelomic fluid. Plant Nematology: Nematology is a science deals with the study of morphology, taxonomy, classification, biology, symptomatology and management of {plant pathogenic} nematode (PPN). The word nematode is made up of two Greek words, Nema means thread like and eidos means form. The words Nematodes is derived from Greek words ‘Nema+oides’ meaning „Thread + form‟(thread like organism ) therefore, they also called threadworms. They are also known as roundworms because nematode body tubular is shape. The movement (serpentine) of nematodes like eel (marine fish), so also called them eelworm in U.K. and Nema in U.S.A. Roundworms by Zoologist Nematodes are a diverse group of organisms, which are found in many different environments. Approximately 50% of known nematode species are marine, 25% are free-living species found in soil or freshwater, 15% are parasites of animals, and 10% of known nematode species are parasites of plants (see figure at left). The study of nematodes has traditionally been viewed as three separate disciplines: (1) Helminthology dealing with the study of nematodes and other worms parasitic in vertebrates (mainly those of importance to human and veterinary medicine).
