Why an invasive pest slug devoured some lettuces while others remain untouched was one of the topics of the honoured master theses (little hint: it were not the salads themselves). The other young plant scientists elucidated specific functions of N-glycosylated proteins in plants, analysed the effects of inhibited chloroplast's development on genetic expression, tested, which substances of an invasive plant contributed to substantial crop failure. One thesis clarified three algal taxa of Trachelomonas, that were validly described already 100 years ago. For the fourth time the German Society for Plant Sciences (DBG) has awarded outstanding MSc theses. This year they were given to three female and two male biologists from the universities of Bielefeld, Münster, Salzburg, Kiel as well as LMU in Munich. The summaries and images of the outstanding works are now on the website.
