Genetic recombination in plants

Current Opinion in Plant Biology, 1998
Meiotic recombination generates novel allelic arrays on chromosomes. Recent experiments have revealed an extraordinarily nonrandom distribution of recombination breakpoints along the lengths of plant chromosomes; for example, recombination breakpoints often resolve within genic sequences, and thereby generate novel alleles.

Genetic Recombination in Streptomyces

Nature, 1955
THE Actinomycetes have properties intermediate between those of the fungi and those of the bacteria. As in practically all bacteria and in many fungi, a sexual cycle is not known to occur in the Actinomycetes. In some bacteria and Fungi Imperfecti1, however, there are parasexual processes2, that is, processes leading to genetic recombination otherwise ...

Genetic analysis of recombination in prokaryotes

Current Biology, 1992
Bacteria provide a simple system for the genetic analysis of homologous recombination. More than twenty genes have been identified in Escherichia coli. The enzymatic activities associated with the products of many of these genes have been revealed by studies with model DNA substrates. It is now possible to pair homologous molecules in vitro and process

Models of Genetic Recombination

Annual Review of Microbiology, 1974
It will be my intention to compare established and recently proposed models for . genetic recombination, with special attention to the separate component principles they contain and the function ofthese principles in the various models. As increasing attention has been paid to realistic details of DNA structure and enzymology, recombination models have

Genetic Recombination in Bacteriophage

1965
Publisher Summary This chapter discusses the genetic recombination in bacteriophage. Although many aspects of the biochemistry, genetics, and general physiology of the system are pertinent to the question of recombination in bacteriophages, the chapter considers only certain facets of the problem. Specifically, the idea of some kind of phosphodiester

Genetic Recombination in Malaria Parasites

Nature, 1971
THE complexity of the life cycle of malaria parasites and the lack of suitable strain characters which could be used as genetic markers have made genetic studies of these organisms difficult. We have now available, however, a number of strains of Plasmodium berghei isolated from wild rodents and mosquitoes in Africa, which can be differentiated from ...

Genetics of Meiosis and Recombination in Mice

2012
Meiosis is one of the most critical developmental processes in sexually reproducing organisms. One round of DNA replication followed by two rounds of cell divisions results in generation of haploid gametes (sperm and eggs in mammals). Meiotic failure typically leads to infertility in mammals.

Recombinant proteins for genetic disease

Clinical Genetics, 1999
The era of molecular biology has led to the development of powerful tools capable of generating therapeutics for genetic disorders. Although there is much current emphasis placed on the development of ‘gene therapy’ for human disease, developments in the production and availability of recombinant proteins are likely to have a more substantial impact on

Genetic recombination in avian retroviruses

Journal of Cellular Biochemistry, 1982
AbstractThe avian retroviruses—and probably other retroviruses as well—undergo a variety of recombinational events with relatively high efficiency. An understanding of the molecular basis of these events should provide insight into the important biological properties these agents exhibit when they become integrated into somatic or germ‐line host cells,

The Theory of Genetical Recombination

1950
Publisher Summary The aim of genetical research is to determine the topography of the genetical material in various organisms and to represent the mutable genes on each chromosome as occupying positions on a linear map. The order and spacing of the genes in the main has to be inferred from the amounts of recombination exhibited by sets of genes when ...
