Gene For Gene

Applications of molecular markers for genetic analysis of host–pathogen systems are presented within the framework of the gene-for-gene model. The literature on complementary genetic interactions in host–pathogen systems is briefly reviewed. Flor's gene-for-gene hypothesis is summarized, and the design, execution, and genetic interpretation of experiments to test this hypothesis are described in detail. Various molecular techniques that have been used to complement the traditional gene-for-gene approach are also briefly reviewed. Three alternative approaches to developing molecular markers using the gene-for-gene framework are presented to illustrate the potential for applying molecular markers in forest tree–pathogen systems. Two of these alternative approaches allow partial confirmation of a hypothesized gene-for-gene genetic model without the usual requirement for advanced pedigrees. Such alternative approaches could greatly accelerate the development of marker-aided selection for disease resistance in forest tree–pathogen systems.

Gene For Gene

Deciphering the gene-for-gene relationships during host-pathogen interactions is the basis of modern plant resistance breeding. In the Verticillium dahliae -tomato pathosystem, two races (races 1 and 2) and their corresponding avirulence ( Avr ) genes have been identified, but strains that lacked these two Avr genes exist in nature.

Aim. To validate the suitability of commercial API 20E test-system (bioMerieux) for the identifi cation and characterization of facultative gram-negative phytopathogenic bacterial isolates. Methods. Conventional mi- crobiological methods, API 20E test-system (bioMerieux) according to the manufacturer’s instructions. Re- sults. The identifi cation results for Erwinia amylovora, Pectobacterium carotovorum and Pantoea agglome- rans isolates were derived from the conventional and API 20E test systems, which, were in line with the literature data for these species. The API 20E test-system showed high suitability for P. agglomerans isolates identifi cation. Although not all the species of facultatively anaerobic phytopathogenic bacteria may be identi- fi ed using API 20E test-system, its application will surely allow obtaining reliable data about their physiologi- cal and biochemical properties, valuable for identifi cation of bacteria, in the course of 24 h. Conclusions. The results of tests, obtained for investigated species while using API 20E test-system, and those of conventional microbiological methods coincided. The application of API 20E test-system (bioMerieux) ensures fast obtain- ing of important data, which may be used to identify phytopathogenic bacteria of Erwinia, Pectobacterium, Pantoea genera.
