As causal agents of bacterial wilt in pastures and meadows, bacteria of the species Xanthomonas translucens are a serious issue in forage grass production. So far, only little is known about host-pathogen interactions at the molecular level and the lack of comprehensive genome data impeded targeted breeding strategies towards resistant forage grass cultivars. Here we announce the draft genome s...
1 An experiment was carried out to test the hypotheses that in heterogeneous environments: (i) the size of species’ root systems will be negatively correlated with their ability to place roots precisely in nutrient-rich patches; (ii) precision of root placement will be less affected by distance to nutrient patches in species with large root systems; (iii) species with greater precision in root ...
The nutritive value of manganese and its occurrence in animal and plant tissue has received considerable attention within the last few years. The literature relating to manganese in plant tissue has been reviewed by Lindow and Peterson (^)^, who reported analyses of 84 samples representing the principal classes of human foods. In a later paper by Skinner and Peterson {12), analyses of 54 feedin...
BACKGROUND Grasses release the most widespread aeroallergens with considerable sensitization rates, while different species produce several pollen concentration peaks throughout the season. This study analyzed the prevalence of grass species in three different European city areas and compared the flowering period of these species with daily pollen concentrations and the symptom loads of grass p...
