Distribution of a Take-All Suppressive Strain of Pseudomonas fluorescens on Seminal Roots of Winter Wheat.
An antibiotic-resistant strain of Pseudomonas fluorescens, that suppresses take-all of wheat, was used to study the distribution of the bacteria on seminal roots of wheat after being introduced onto seeds. Cells of P. fluorescens were isolated from the entire length of the root, and density of the introduced bacteria declined with the distance from the base of the root. Maximum populations of 1...
متن کاملTake-all of Wheat and Natural Disease Suppression: A Review
In agro-ecosystems worldwide, some of the most important and devastating diseases are caused by soil-borne necrotrophic fungal pathogens, against which crop plants generally lack genetic resistance. However, plants have evolved approaches to protect themselves against pathogens by stimulating and supporting specific groups of beneficial microorganisms that have the ability to protect either by ...

15 صفحه اولDetection of Molecular Markers Linked To Bread Wheat Take-All Disease (Gaeumannomyces Graminis Var. Tritici) T-41 Isolation
Take-all is one of the most important diseases of wheat in wet areas, causing significant damage in these areas, and there has not introduced any resistant varieties against this disease until now. Therefore, efforts to identify the resistance genes to this disease and developing resistant varieties or cultivars with lower susceptible in bread wheat have a great importance.In this research...
متن کاملCut-off Sampling Design: Take all, Take Some, and Take None
Extended Abstract. Sampling is the process of selecting units (e.g., people, organizations) from a population of interest so that by studying the sample we may fairly generalize our results back to the population from which they were chosen. To draw a sample from the underlying population, a variety of sampling methods can be employed, individually or in combination. Cut-off sampling is a pr...
