Production of protease isozymes by Aphanomyces cochlioides and Aphanomyces euteiches
The production of protease activity by the sugarbeet pathogen Aphanomyces cochlioides, the legume pathogen A. euteiches, and the fish pathogen Saprolegnia parasitica was examined. Protease activity was readily detected in supernatants of water cultures of each organism using autoclaved host tissue as a nutrient source. Most of the protease isozymes extracted from sugarbeet and pea seedlings inf...
متن کاملRoot Rot of Pea Caused by Aphanomyces euteiches
Aphanomyces root rot, caused by the oomycete Aphanomyces euteiches, is the most important and destructive disease of pea. Since the inoculum is persistent in the soil, and no resistant cultivars or means of chemical control are available, the disease is difficult to manage. The occurrence of soil suppressiveness against the disease was previously reported, and the main aim of this study was to ...

The effect of polyene antibiotics upon growth and sterol-induction of oospore production by Pythium periplocum was studied. Filipin and fungichromin markedly inhibited growth and prevented reproduction. Amphotericin B also prevented oospore production but only slightly inhibited growth. Pimaricin slightly inhibited growth and greatly decreased reproduction. Nystatin usually had no effect on gro...
متن کاملAssociation between border cell responses and localized root infection by pathogenic Aphanomyces euteiches.
BACKGROUND AND AIMS The oomycete Aphanomyces euteiches causes up to 80 % crop loss in pea (Pisum sativum). Aphanomyces euteiches invades the root system leading to a complete arrest of root growth and ultimately to plant death. To date, disease control measures are limited to crop rotation and no resistant pea lines are available. The present study aims to get a deeper understanding of the earl...
