Root 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 ...
متن کاملProduction 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 کاملComparative Genome-Wide-Association Mapping Identifies Common Loci Controlling Root System Architecture and Resistance to Aphanomyces euteiches in Pea
Combining plant genetic resistance with architectural traits that are unfavorable to disease development is a promising strategy for reducing epidemics. However, few studies have identified root system architecture (RSA) traits with the potential to limit root disease development. Pea is a major cultivated legume worldwide and has a wide level of natural genetic variability for plant architectu...
متن کاملEffect of arabinogalactan proteins from the root caps of pea and Brassica napus on Aphanomyces euteiches zoospore chemotaxis and germination.
Root tips of many plant species release a number of border, or border-like, cells that are thought to play a major role in the protection of root meristem. However, little is currently known on the structure and function of the cell wall components of such root cells. Here, we investigate the sugar composition of the cell wall of the root cap in two species: pea (Pisum sativum), which makes bor...
متن کاملHierarchical Analysis of Diversity, Selfing, and Genetic Differentiation in Populations of the Oomycete Aphanomyces euteiches.
ABSTRACT Relatively little is known about the population biology of the legume pathogen Aphanomyces euteiches. A. euteiches is a soilborne pathogen causing Aphanomyces root rot of several legumes, including alfalfa, bean, lentil, and pea. Our objectives were to assess the degree of diversity, selfing, and population differentiation in A. euteiches. We contrasted populations within and among two...
