متن کاملMolecular Taxonomy of Phytopathogenic Fungi: A Case Study in Peronospora
BACKGROUND Inappropriate taxon definitions may have severe consequences in many areas. For instance, biologically sensible species delimitation of plant pathogens is crucial for measures such as plant protection or biological control and for comparative studies involving model organisms. However, delimiting species is challenging in the case of organisms for which often only molecular data are ...
متن کاملXeromorphism of trichomes in Lamiaceae species
The xeromorphic adaptation of epidermal cells of Lamiaceae plant leaves, the conse quence of their adaptation to an arid habitat, was investigated. These xerophytic species inhibit transpiration in different ways, depending on the number, the form and the position of trichomes, whether they are dead hairs or live glandular structures. The Salvia genus is characterized on one hand by multicellu...

متن کاملLight Suppresses Sporulation and Epidemics of Peronospora belbahrii
Peronospora belbahrii is a biotrophic oomycete attacking sweet basil. It propagates asexually by producing spores on dichotomously branched sporophores emerging from leaf stomata. Sporulation occurs when infected plants are incubated for at least 7.5h in the dark in moisture-saturated atmosphere at 10-27°C. Exposure to light suppresses spore formation but allows sporophores to emerge from stoma...
