Project description:Our experiments investigated the effects of various known chemotherapeutic agents (2-thiouracil, ribavirin and zidovudine) on grapevine for the elimination of several different viruses and viroids. Viruses and viroids were identified by small RNA HTS in the mother plants of different grapevine cultivars, and RT-PCR verified the results. Among the tested agents, ribavirin had the broadest elimination effect on most viruses. It proved to be particularly effective against GFkV, GLRaV-4, GPGV and GRSPaV, however, as a single treatment it was not able to eliminate GFLV. In our experiments, ribavirin also showed very low efficacy against GLRaV-1 and GVA viruses. The application of 2-TU caused high phytotoxicity, with only 25% efficacy against GLRaV-4 among the viruses tested. Zidovudine failed to eliminate any of the viruses we tested. However, the combination of ribavirin and zidovudine was able to eliminate GFLV, though with low efficacy (12.5%). In contrast, the combination of ribavirin and 2-TU has been shown to be very effective against GRSPaV and GPGV. Compared to ribavirin, zidovudine and 2-thiouracil did not demonstrate significant virus elimination efficacy in the case of tested viruses. In our experiments ribavirin could not remove HSVd and GYSVd-1 viroids. To the best of our knowledge, no prior studies have been published the successful use of ribavirin or other chemotherapeutic agents against GLRaV-4, and this is the first publication of a successful application of 2-TU and zidovudine against grape viruses .

Project description:Several recombinat viruses of porcine circovirus type 2 (PCV2),including P1, P2, ZJ-R, VL258, and VL264, have been found. The PK15 cells were transfected by the molecular clones of the abovementioned viruses, where specific sets of genes are up-regulated or down-regulated. We used microarrays to detail the global programme of gene expression and identified distinct functions of viruses or viral proteins. PK15 cells were selected at 12 hours post-transfection for RNA extraction and hybridization on Affymetrix microarrays. We sought to obtain the gene expression patterns of PK15 cells transfected with different molecular clones of the viruses.

Project description:To explore the influence of virus-accumulation on garlic growth, we produced a virus-free garlic using the landrace “Chalingzipisuan” with great accumulation of viruses, based on the shoot-tip culture. Then, using the viruses-accumulated garlic and corresponding virus-free garlic, we performed a transcriptomic investigation for the enlarging-growth bulbs, and identified 1,182 garlic genes with differential expression, suggesting these genes involved in the response to viruses-infection

Project description:Millet is a dangerous weed in Hungary. Lack of seed dormancy helps it to spread easily and be present at maize, wheat and other crop fields. Our previous report revealed the possibility that millet can also play a role as a virus reservoir. In that study we detected the presence of several viruses in millet using DAS ELISA. Because serological methods can only detect the presence of the investigated particular pathogens, we suspected that other, previously unknown viruses can also be present in this weed. To investigate this theory, we randomly sampled two locations and collected millets showing stunting, chlorosis, and striped leaves and investigated the presence of viruses using small RNA HTS as a diagnostic method. Our result confirmed the widespread presence of wheat streak mosaic virus at both locations. Moreover, barley yellow striate mosaic virus and barley virus G were also identified, which have not been described from Hungary before. As these viruses can cause severe diseases on wheat, their presence on a weed mean a potential infection risk. Our study indicates that the presence of millets on the fields needs a special control in order to prevent emergence of new diseases at crop fields.
