Y‐satellite RNA (Y‐sat) of cucumber mosaic virus upregulates the expression aphid ABCG4 gene, which promotes wing formation. We used virus‐induced gene silencing (VIGS) to prevent wing‐induction mechanism Y‐sat and thus inhibited Of aphids on plants with VIGS , only about 30% had wings, 60–70% winged were small likely impaired in flying ability. In addition, we showed that double‐stranded RNAs ...
Plants of Viola cornuta displaying typical virus symptoms were observed during spring 2003 in a plant nursery in Córdoba, central Argentina. Electron microscopic examinations of symptomatic leaf samples revealed the presence of isometric virus-like particles about 30 nm in diameter. Subsequent serological analysis allowed the identification of the pathogen as a subgroup I strain of Cucumber mos...
جنس cucumovirus یکی از اعضای خانواده bromoviridae می باشد و سه عضو ویروس موزاییک خیار، ویروس کوتولگی بادام زمینی و ویروس بی بذری گوجه فرنگی را شامل می شود.جدایه های ویروس موزاییک خیار بر اساس روش های سرولوژیک، نقشه پپتیدی پروتئین پوششی و تشابه ژنومی rna های ویروس گروه بندی می گردند. روش های مبتنی بر pcr نسبت به روش های سرولوژیک دارای حساسیت بیشتری هستند. جدایه های ویروس موزاییک خیار بر اساس ژن ...
A viral disease causing severe mosaic, necrotic, and yellow symptoms on Vigna angularis var. nipponensis was prevalent around Suwon area in Korea. The causal virus was characterized as Cucumber mosaic virus (CMV) on the basis of biological and nucleotide sequence properties of RNAs 1, 2 and 3 and named as CMV-wVa. CMV-wVa isolate caused mosaic symptoms on indicator plants, Nicotiana tabacum cv....
Viruses are obligate intracellular symbionts. Plant viruses are often discovered and studied as pathogenic parasites that cause diseases in agricultural plants. However, here it is shown that viruses can extend survival of their hosts under conditions of abiotic stress that could benefit hosts if they subsequently recover and reproduce. Various plant species were inoculated with four different ...
