Genetic and physical maps illustrate the arrangement of genes and DNA markers on a chromosome. The relative distances between positions on a genetic map are calculated using recombination frequencies while a physical map is based on the actual number of nucleotide pairs between loci. These maps are...
Genome-wide integrated genetic and physical maps have provided powerful tools and infrastructure for advanced genomics research of human and other animal and plant model species. They are not only crucial for large-scale genome sequencing, but also provide powerful platforms required for many other asp...
However, the physical distance between these probes was determined to encompass about 70% of the physical length of chromosome 9. The two markers were located at distal positions on opposite arms of chromosome 9. Physical maps provide valuable information for gene isolation and understanding ...
The alignment of genetic and physical maps presented here should facilitate the continued analysis of essential genes in Arabidopsis and further characterization of a broad spectrum of mutant phenotypes in a model plant. 展开 关键词: Arabidopsis DNA, Bacterial Genetic Techniques Chromosome Mapping Cloning...
Pulsed-field gel electrophoresis (PFGE) is a useful tool for analysis of differences in the genome structure of many strains, and over a hundred of genome maps have been constructed. Our previous PFGE analysis of B. fragilis revealed an apparent difference between the genome structures of type ...
172 mapped markers were absent in the current B73 assembly and their placement can be used for future improvements of the B73 reference sequence. Colinearity of the genetic and physical maps was mostly conserved with some exceptions that suggest errors in the B73 assembly. Five major regions ...
Barley (Hordeum vulgare L.) is among the world’s earliest domesticated and most important crop plants. It is diploid with a large haploid genome of 5.1 gigabases (Gb). Here we present an integrated and ordered physical, genetic and functional sequence r
and the progressive withdrawal of synthetically-derived nematicides due to animal, human and environmental concerns11,12are the main drives for the exploitation and use of environmentally-friendly strategies. Currently, genetic host plant resistance is a very effective and viable strategy to control ...
Genetic maps use landmarks called markers. Many different types of markers can be used, and some markers can be used for both physical mapping and genetic mapping. Genes with a specific phenotype are very useful markers for mapping. Unfortunately, not enough genes with visible phenotypes exist ...
a, Number of reported physical protein–protein interactions as a function of the number of phenotypes analysed in this study affected by a gene. b, As in a but with genes categorized as affecting either few (one or two; 1,478 genes) or many (three or more; 510 genes) traits. Two-si...
