Silicon plays an important role in providing tolerance to various abiotic stresses and augmenting plant resistance against diseases. However, there is a paucity of reports about the effect of silicon on bacterial and viral pathogens of plants. In general, the effect of silicon on plant resistance against bacterial diseases is considered to be due to either physical defense or increased biochemical...
Turnip mosaic virus (TuMV) is the most important and widespread virus infecting brassicas worldwide. In 2013, 2014, and 2015, twenty-three cabbage (Brassica oleracea L.) breeding lines from Black Sea Agricultural Research Institute (BSARI, Samsun, Turkey) were screened for their reaction to TuMV-BA isolate by mechanical inoculation under controlled conditions. On the basis of 0–5 disease rating scale...
A panel of four monoclonal antibodies (MAbs) was used to study the immunological profile of Rice yellow mottle virus (RYMV) genus Sobemovirus. Serological profiles of 35 representative isolates of RYMV from Borno, Gombe, Kaduna, Kano, Niger, Sokoto and Zamfara states in Northern Nigeria. All the RYMV isolates were classified into three major serogroups (SG1, SG2 and SG3) and further separated into...
Viral diseases are a worldwide problem of blueberry which a major limiting factor for production. A survey for Blueberry scorch virus (BlScV) by DAS-ELISA in various organs of highbush blueberry conducted from May 2010 to April 2011, showed the occurrence of these virus in cvs Bluecrop and Herbert, which showing virus-like symptoms. Samples of plant materials (bud flower, flower, leaf, bark) were...
Choroba zbóż wywołana przez kompleks wirusów BaYMV/BaMMV rozpowszechniona w Europie Zachodniej, ma również duże znaczenie w Polsce. Obecnie zmapowanych jest 17 genów odporności na kompleks tych wirusów. Uwzględniając rozmieszczenie genów odporności w genomie jęczmienia możliwa jest celowa kumulacja tych genów w nowych odmianach. Celem badań było określenie zmienności allelicznej w loci Hv-eIF4E i...
Susceptibility of various potato cultivars to Clavibacter michiganensis subsp. sepedonicus infection was estimated in field experiments in Bydgoszcz in 2008–2009. Ten tubers of each of several potato cultivars were inoculated with suspension of Cms BPR IOR 527 at concentration about 108 cfu/ml. Differences among the cultivars in the incidence of foliar and tuber ring rot symptoms and of latent infection...
Diversity of three isolates of Zucchini yellow mosaic virus (ZYMV) was analyzed by the biological and genetic characterization. Two isolates were collected from zucchini plants and one from cucumber. The symptoms induced on most hosts were different. In addition, analysis of the coat protein (CP) and nuclear inclusion protein b (Nib) of the ZYMV genome revealed high level of nucleotide variability...
Oceniono stan porażenia przez wirusy roślin z rodzaju Sambucus przy pomocy metody biologicznej i serologicznej (DAS-ELISA). Przedmiotem badań były młode rośliny pochodzące ze szkółek komercyjnych, starsze rośliny wchodzące w skład kolekcji odmian bzu dwóch firm oraz rośliny ze stanowisk naturalnych. Na podstawie wyników testu biologicznego i serologicznego stwierdzono, że rośliny bzu są porażone przez...
