A comparison of oomycete diversity in reed stands ( Phragmites australis ) of Lake Constance, Germany, and maize fields close by provided evidence for the occurrence of natural hybridization between Pythium phragmitis , a newly described reed pathogen, and an as-yet unknown Pythium species closely related to P. phragmitis and P. arrhenomanes . Internal transcribed spacer and β -tubulin sequence...

AIMS Four well-described strains of Pseudomonas fluorescens were assessed for their effect on pea growth and their antagonistic activity against large Pythium ultimum inocula. METHODS AND RESULTS The effect of Pseudomonas strains on the indigenous soil microflora, soil enzyme activities and plant growth in the presence and absence of Pythium was assessed. Pythium inoculation reduced the shoot...

The kingdom Stramenopile includes diatoms, brown algae, and oomycetes. Plant pathogenic oomycetes, including Phytophthora, Pythium and downy mildew species, cause devastating diseases on a wide range of host species and have a significant impact on agriculture. Here, we report comparative analyses on the genomes of thirteen straminipilous species, including eleven plant pathogenic oomycetes, to...

Stand problems consistently cause significant production losses and management problems in Arkansas rice fields. Previous research, funded by the Rice Research and Promotion Board, identified the role of environmental factors and soilborne plant pathogens in limiting rice stand establishment, and had the goal of determining the conditions where soilborne pathogens, especially Pythium species, p...

A DNA array containing 172 oligonucleotides complementary to specific diagnostic regions of internal transcribed spacers (ITS) of more than 100 species was developed for identification and detection of Pythium species. All of the species studied, with the exception of Pythium ostracodes, exhibited a positive hybridization reaction with at least one corresponding species-specific oligonucleotide...

The author investigated aquatic fungi developing on the seeds of some plants in various types of water bodies of Podlasie Province. The bait method was used to isolate the fungi. Seventy-four aquatic fungal species were found on seeds of three species of plants: Cannabis sativa hemp-seeds 59, Fagopyrum esculentum buckwheat-seeds 55 and on Vicia sativa vetch-seeds 44 in water of four various bod...

Calopteryx splendens males exhibit a remarkable variation in wing pigmentation both within and between populations. In this study, we examined whether the wingspots of male C. splendens are related to male quality. We measured the nylon implant encapsulation rate for 85 males and found that males with larger wingspots had a faster encapsulation rate, indicating a better immunocompetence. We als...

Damping-off diseases incited by different species of Pythium are a persistent problem worldwide, often resulting in reduced yields and occasionally resulting in major crop damage. There have been increasing restrictions on the use of chemical fungicides, and the development of disease-suppressive biocontrol agents has become a major goal of horticulture crops. An experiment was conducted with t...

Viable biocontrol agents for mosquito control are quite rare, therefore improving the efficacy of existing biological agents is an important study. We need to have a better understanding of the predation-risk behavioral responses toward prey. This research examined prey choices by Toxorhynchites splendens by monitoring the behavioral responses of Aedes aegypti, Aedes albopictus, and Anopheles s...
