Construction of Whole Genome Radiation Hybrid Panels and Map of Chromosome 5A of Wheat Using Asymmetric Somatic Hybridization
To explore the feasibility of constructing a whole genome radiation hybrid (WGRH) map in plant species with large genomes, asymmetric somatic hybridization between wheat (Triticum aestivum L.) and Bupleurum scorzonerifolium Willd. was performed. The protoplasts of wheat were irradiated with ultraviolet light (UV) and gamma-ray and rescued by protoplast fusion using B. scorzonerifolium as the re...
متن کاملIdentification of point mutations in mixtures by capillary electrophoresis hybridization.
We have developed a rapid method for unambiguous identification and mutant fraction determination of individual mutants in mixtures of DNA sequence variants each differing by one or a few nucleotides. This method has applications to such diverse areas as interpretation of mutational spectra, screening of populations for polymorphisms and identification of species in environmental mixtures. In o...
متن کاملSomatic mutations and proteins
A large body of data has now been accumulated concerning the ways in which heritable mutations can affect protein structure. Such mutations are usually presumed to arise in the germ line, and are studied by progeny analyses of various types. Today, I would like to consider how somatic mutations might be genetically predisposed and thereby made available to an organism during its adaptation to e...
متن کاملTransfer of resistance traits from carrot into tobacco by asymmetric somatic hybridization: Regeneration of fertile plants.
Transfer of methotrexate and 5-methyltryptophan resistance from carrot (Daucus carota) to tobacco (Nicotiana tabacum) was achieved by fusion between leaf mesophyll protoplasts of tobacco and irradiated cell culture protoplasts of carrot. Some of the regenerated somatic hybrids exhibited normal tobacco morphology with coexpression and independent segregation of the transferred resistance markers...
متن کامل[Haldane's rule and somatic mutations].
Haldane's rule stating that viability and fertility in the heterogametic sex of hybrids are lower than in the homogametic sex is explained on the basis of the assumption that diploidy is aimed at protecting individuals having large body size and large genomes from somatic mutations. The presence of hemizygous sex chromosomes, which are effectively haploid in the heterogametic sex, results in th...
