Nematophagous fungi are parasites of nematodes, thus they have been considered and tested for biological control of parasitic nematodes, but so far with limited success. Due to the fact that the nematode cuticle is composed of proteins it is likely that fungal extracellular proteases are involved in the infection of nematodes. I have isolated a gene (designated PII) encoding an extracellular cutic

Popular Abstract in Chinese 在世界許多地方蛾類幼蟲是主要的農業害蟲，但也有蛾類養殖業為獲取其絲綢蠶繭，例如家蠶。其實它也是第一個也是最好的研究揮發性有機分子用於傳遞信息的昆蟲研究模型。一般來說是雌蛾釋放信息素通過很長的距離來吸引雄性同類，而且具有出色的靈敏度和特異性。至今有記載的蛾類信息素都屬於同一類化合物(脂肪酸衍生物), 在信息素腺體內合成。信息素的生物合成涉及到脂肪酸的脫飽合，碳鏈縮短，並最終還原，乙酰化或氧化成醛等。這些反應過程中的酶已經進化到具有專一性，專門用於生產複雜的化學信號，使得蛾類的信息素存在豐富的化學多樣性。在本論文中，首先對幾個脫飽和酶進行研究。第一篇文章對冬尺蠖的脫飽合酶進行克隆並在酵母中通過異源表達證明了它具有把順十一,順十四,順十七-二十碳三烯酸轉化成順十一,順十四,順十七,十九-二十碳四烯酸的能力。這是有史以來第一個對甲基端脫飽合酶Moth caterpillars are major agricultural pests in many parts of the world. In general female moths attract male mates with their pheromone over long distance. Most of the described moth pheromones belong to the same class of chemical compounds, fatty acid derivatives that are produced de novo in the pheromone gland. The pheromone biosynthesis involves desaturation, chain-shortening by β-oxidation

Nematode-trapping fungi are soil living organisms with the ability to infect and kill nematodes. These fungi have developed specialized infection structures, traps for the capture of nematodes. To be able to identify genes in nematode-trapping fungi that are involved in the infection of nematodes cDNA microarrays were constructed. The cDNA microarrays were printed with cDNA reporers obtained from

The main purpose of this book is to help musicians develop their rhythmic skills. By practicing different kinds of rhythmic phrases such as odd grouping, odd metres, combined metres and metric modulations you can strengthen your rhythmic sense and expand your rhythmic freedom. Instrumentalists often spend a lot of time developing their harmonic and melodic skills in improvisa- tion without practic

Risk-taking in financial markets is highly correlated between parents and their children; however, little is known about the extent to which these relationships are genetic or determined by environmental factors. We use data on stock market participation of Swedish adoptees and relate this to the investment behavior of both their biological and adoptive parents. We find that stock market participa

Popular Abstract in Swedish Det försurande nedfallet över Europa har minskat kraftigt sedan 1970- och 1980-talen. Detta beror delvis på framgångsrikt arbete inom konventionen om långväga gränsöverskridande luftföroreningar (LRTAP), inom ramen för FN:s ekonomiska kommission för Europa (UNECE). Marken i många områden i Sverige och övriga Europa är fortfarande kraftigt försurad trots det minskade nedDynamic biogeochemistry models are important tools for determining the time-scales of recovery from acidification. In the review process of the 1999 UNECE LRTAP Gothenburg protocol, results from dynamic models will probably be included when determining further reductions of acidifying emissions. This thesis describes modeling of recovery from acidification using the dynamic multi-layer soil chemi

The concept of packaging logistics focuses on the synergies achieved by integrating logistics and packaging systems with the potential of increased supply chain efficiency and effectiveness, through the improvement of packaging and logistics related activities. The retail supply chain is a major consumer of different types of packaging. In Sweden alone, retailers handle approximately 1000 million

The purpose of this paper is to propose a new approach for categorizing the body of knowledge captured in the existing literature, past and present in such a way that contributions to the use side of systems development are made explicit. The new twist of this approach is that it seeks to bridge the most prevalent divides currently fragmenting the IS literature by offering an integrative classific
