• Parasitism and saprotrophic wood decay are two fungal strategies fundamental for succession and nutrient cycling in forest ecosystems. An opportunity to assess the trade-off between these strategies is provided by the forest pathogen and wood decayer Heterobasidion annosum sensu lato. • We report the annotated genome sequence and transcript profiling, as well as the quantitative trait loci mapping, of one member of the species complex: H. irregulare. Quantitative trait loci critical for pathogenicity, and rich in transposable elements, orphan and secreted genes, were identified. • A wide range of cellulose-degrading enzymes are expressed during wood decay. By contrast, pathogenic interaction between H. irregulare and pine engages fewer carbohydrate-active enzymes, but involves an increase in pectinolytic enzymes, transcription modules for oxidative stress and secondary metabolite production. • Our results show a trade-off in terms of constrained carbohydrate decomposition and membrane transport capacity during interaction with living hosts. Our findings establish that saprotrophic wood decay and necrotrophic parasitism involve two distinct, yet overlapping, processes.

During the picking season in the Norwegian plum production areas, the harvested plums are brought to cold storage in packing houses once or twice a day. Plums picked late in the afternoon may even not be cooled properly until the next day. The average time from picking until the plums are placed in a cold storage is approximately 8 hours. Previous reports have shown that delayed cooling of sweet cherries and apples reduced the fruits’ susceptibility to physiological or fungal decay. An experiment was performed in order to evaluate the impact of different delay-to-cold storage times (0, 5, 10, 15 and 25 hours) on quality and phenolic contents changes of Norwegian ‘Mallard’ plums during cold storage, transport, and retail in normal atmosphere (NA). The fruits (10 fruits in PE tray, n=3) were stored for 14 days at 1°C, followed by 3 days at 7°C and then for 4 days at 20°C. Fruit quality parameters (firmness, colour in CIE L, a*, b* colour space, weight, rot occurrence (%)) and total phenol and anthocyanin content were determined. Samples were analyzed just before cold storage and then after 14 days at 1°C, 3 days at 7°C, or 4 days at 20°C. Evaluation of results has shown that delay of cooling has a retarding effect on rot development during 20°C storage (post cold transport), weight loss and stimulates anthocyanin accumulation and colour changes to some extent. At the end of storage no effect on fruit firmness could be observed.

The flavor of apples after storage is important to the consumers. Most often factors like decay, firmness and the contents of soluble solids and acidity are regarded as the limiting factors for storability of apples. The amount of volatile aroma compounds is less studied. Using head space analyses the amounts of 8 compounds known to be important to aroma of apples were studied during storage. Some compounds increased while others decreased during storage. Apples of three cultivars and from trees treated with foliar fertilization with nitrogen and calcium were included. The early ripening cultivar ‘Discovery’ had more aroma compounds in November and less in February. In the late ripening cultivar ‘Elstar’ the content of aroma compounds was low in November. However, the amounts were more than doubled in February. The foliar fertilization with nitrogen tended to reduce the amount of aroma compounds while the highest content was found in apples from trees treated with calcium. However, these tendencies were not statistically significant. In ‘Discovery’ the content of aroma compounds may be a limiting factor to the storability of this cultivar.

The present paper comments on thirty-three of the forty-seven species belonging to six Agromyzidae genera and presently known to occur in Norway. Thirteen species are reported new to the Norwegian fauna belonging to the family Agromyzidae. The species are: Amauromyza (Cephalomyza) chenopodivora Spencer, 1971, Amauromyza (Cephalomyza) monfalconensis (Strobl, 1909), Cerodontha (Butomomyza) rohdendorfi Nowakowski, 1967, Cerodontha (Butomomyza) scutellaris (Roser, 1840), Cerodontha (Cerodontha) fulvipes (Meigen, 1830), Cerodontha (Cerodontha) stackelbergi Nowakowski, 1972, Cerodontha (Dizygomyza) caricicola (Hering, 1926), Cerodontha (Icteromyza) capitata (Zetterstedt, 1848), Cerodontha (Poemyza) pygmina (Hendel, 1931), Metopomyza flavonotata (Haliday, 1833), Metopomyza scutellata (Fallen, 1823), Metopomyza xanthaspioides (Frey, 1946) and Aulenagromyza buhri (de Meijere, 1938). In addition new regional data is given for twenty species previously reported from Norway. The biology of the larva, when known, and the distribution in Norway and Europe are commented on for each of the species.
