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 کاملDevelopment of codominant simple sequence repeat, single nucleotide polymorphism and sequence characterized amplified region markers for the pea root rot pathogen, Aphanomyces euteiches.
Three kinds of genetic markers including simple sequence repeats (SSRs), single nucleotide polymorphisms (SNPs) and sequence characterized amplified regions (SCARs) were developed from Aphanomyces euteiches. Of 69 loci tested, seven SSR, two SNP and two SCAR markers were codominantly polymorphic. These codominant markers and dominant markers described herein will facilitate population genetic a...
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 کاملStatus of Aphanomyces Root Rot in Wisconsin
Alfalfa is the primary forage crop in Wisconsin and is a key element in the state’s dairy industry. The yield of new varieties is greater than that of Vernal and other older varieties due to genetic gains made by breeders over the years. Much of the yield advantage of new varieties may be attributed to efforts to breed for resistance to a wide variety of major pathogens of alfalfa such as Verti...
متن کاملCharacteristics and Frequency of Aphanomyces euteiches Races 1 and 2 Associated with Alfalfa in the Midwestern United States
Aphanomyces euteiches Drechs. causes economically important root rot diseases of several legume species when wet soil conditions prevail. This soilborne oomycete pathogen causes severe root rot damage to pea (Pisum sativum L.), alfalfa (Medicago sativa L.), snap bean (Phaseolus vulgaris L.), and red clover (Trifolium pratense L.) (12,21,22,24,25,29). A. euteiches was first described as an impor...
