In the present study, field surveys were conducted to detect potential associational susceptibility of crop plants (potato, alfalfa and maize) caused by Canadian goldenrod, Solidago canadensis (L.), one most common invasive weeds in Central Eastern Europe, via plant associated virus vectoring aphids. Assessments made two major agricultural land types: crops grown under high input vs. low-input ...

Plant viruses that are members of the Geminiviridae family have circular single-stranded DNA (ssDNA) genome and are responsible for major crop diseases worldwide. We have identified and characterized a novel monopartite geminivirus infecting tomato in Argentina. The full-length genome was cloned and sequenced. The genome-wide pairwise identity calculation that resulted in a maximum of 63% ident...

No. Poster–73 IMPACT OF COTTON LEAF CURL DISEASE (CLCuD) ON YIELD AND QUALITY OF FIBRE IN Bt COTTON IN PUNJAB Daljeet Singh, J.S. Gill, R.K. Gumber and Ramandeep Singh Punjab Agricultural University, Regional Station, India Cotton is one of the most important cash crops in India. Cotton leaf curl disease (CLCuD) , caused by a single stranded circular Gemini virus consisting of DNA A and two sat...

Urdbean leaf crinkle virus (ULCV) is a common, wide spread, destructive and economically important disease causing systemic infection in blackgram (Vigna mungo (L.) Hepper), resulting in extreme crinkling, curling, puckering and rugosity of leaves, and yield reductions. Effect of viral infection was investigated on total soluble proteins and antioxidant enzymes activity in two genotypes viz., M...

Tomato yellow leaf curl virus (TYLCV), a member of the genus Begomovirus, is one of the most important viruses of cultivated tomatoes worldwide, mainly causing yellowing and curling of leaves with stunting in plants. TYLCV causes severe problems in sub-tropical and tropical countries, as well as in Korea. However, the mechanism of TYLCV infection remains unclear, although the function of each v...

The common uncultivated plants, Datura stramonium, Jatropha curcas, Croton bonplandianum, Acalypha indica and Ageratum conyzoides are grown in and around the cultivated fields of sub-Himalayan north-east Indian plains. Chlorosis, leaf curling, distortion, yellowing and stunted growth symptoms are often found in the plants mentioned. Yellow vein mosaic diseases caused by begomoviruses, associate...

RING (really interesting new gene)-H2 domain-containing proteins are widely represented in plants and play important roles in the regulation of many developmental processes as well as in plant-environment interactions. In the present report, experiments were performed to unravel the role of the poplar gene PtaRHE1, coding for a RING-H2 protein. In vitro ubiquitination assays indicate a function...
