The analysis of provenance means indicated that, at least for the southern range, the disease ratings were correlated with foliage color. Expression of resistance gene analogs in woodland strawberry (Fragaria vesca) during infection with Phytophthora cactorum. Almost all investigations of genetic variation in resistance have been performed using cold acclimated plants. To reduce the risk of HT-2/T- 2-contaminated grain lots to enter the food and feed chain, it is important to identify factors that influence F. A three-year survey was performed to reveal more of the life cycle of F. The role of infected flower petals and leaves, and precipitation in predicting sclerotinia stem rot in oilseed rape (Lecture). Talgø, V., Schmitz, S., Chandelier, A., Brurberg, M. In general, the more bluish the foliage was, the healthier the trees appeared. Global transcriptome changes in perennial ryegrass during early infection by pink snow mould. doi: 10.1038/srep28702 vellykket dating historier Lack of resistance to pink snow mould (Microdochium nivale) is a major constraint for adaptation of perennial ryegrass (Lolium perenne L.) to continental regions with long-lasting snow cover at higher latitudes. Since these toxins are frequently detected at high levels in oat grain lots, they pose a considerable risk for food and feed safety in Norway, as well as in other north European countries. Baiting for Phytophthora in waterways associated with Christmas tree production in Norway, Belgium and Denmark.
doi: 10.1094/PHP-BR-14-0022Davik, J., Eikemo, H., Brurberg, M. vesca genotypes concluded that resistance to crown rot is inherited as a dominant trait under nuclear control. Phytophthora survives the digestive system of the invasive slug Arion vulgaris. The different types of materials were also analysed for the presence F. langsethiae DNA may occur in the oat plant already before heading and flowering. langsethiae DNA was observed in crop residues and weeds, though at relatively low levels. Of the arthropods that were associated with the collected oat plants, aphids and thrips species were dominating. At a later stage, this shifted, and most potato defense genes were turned on, especially those involved in terpenoid biosynthesis when H. Some biocontrol-activated defense-related genes in potato were upregulated during early interaction with C. rosea are probably due to a combination of mechanisms, including mycoparasitism, biocontrol-activated stimulation of plant defense mechanisms, microbial competition for nutrients, space, and antibiosis. graminearum DNA, the most important deoxynivalenol producer observed in Norwegian cereals, and which presence has shown a striking lack of correlation with the presence of F. Both effectors contain positively selected amino acids. In Norway in northern Europe, it is assumed that these taxa do not reproduce sexually due to low temperatures in the autumn when the plants are flowering. Results were higher than earlier reports for maize from Ethiopia. To validate this hypothesis and to map the insect species potentially involved in SRE dispersal, we have analyzed the occurrence of SRE in insects recovered from potato fields over a period of 2 years. Since these toxins are frequently detected at high levels in oat grain lots, they pose a considerable risk for food and feed safety in Norway, as well as in other north European countries. The nucleotide sequence of this genome was deposited into NCBI Gen Bank under the accession CP017674. B., Usoltseva, M., Dahl, Å., Kvalbein, A., Normann, K. Koch’s postulates were fulfilled, confirming the S. This is the first report of turfgrass dollar spot in Sweden and only the second report of the disease from Scandinavia. H., Lefrancois, A., Elameen, A., Glorvigen, B., Lees, A. Hence, breeding efforts should concentrate on quantitative resistance that is effective against all genotypes of the pathogen. These findings are useful for intervention measures to reduce the impact of the main fungal species and their associated mycotoxins, by creating awareness and implementation of good agricultural practices. graminearum DNA, the most important deoxynivalenol producer observed in Norwegian cereals, and which presence has shown a striking lack of correlation with the presence F. More results from this work will be presented at the meeting. A majority of the polymorphisms and all selected sites are located in the effector C-terminal region, which is responsible for their function inside host cells. The main objective of this study was to examine the genetic variation of invasive Fallopia taxa in selected areas in Norway in order to evaluate whether the taxa may reproduce by seeds in their most northerly distribution range in Europe. Twenty-eight yellow sticky traps were set up in 10 potato fields throughout Norway to attract and trap insects. To reduce the risk of HT-2/T- 2-contaminated grain lots to enter the food and feed chain, it is important to identify factors that influence F. A three-year survey was performed to reveal more of the life cycle of F. Because pesticides are rarely used in the cultivation of Scandinavian turfgrass, dollar spot disease may prove difficult to control through conventional means and potentially represents a major threat to the industry.
