Genomics is a discipline in genetics concerned with the study of the genomes of organisms. The field includes efforts to determine the entire DNA sequence of organisms and fine-scale genetic mapping. The field also includes studies of intragenomic phenomena such as heterosis, epistasis, pleiotropy and other interactions between loci and alleles within the genome. In contrast, the investigation of the roles and functions of single genes is a primary focus of molecular biology or genetics and is a common topic of modern medical and biological research. Research of single genes does not fall into the definition of genomics unless the aim of this genetic, pathway, and functional information analysis is to elucidate its effect on, place in, and response to the entire genome s networks. For the United States Environmental Protection Agency, "the term "genomics" encompasses a broader scope of scientific inquiry associated technologies than when genomics was initially considered. A genome is the sum total of all an individual organism s genes. Thus, genomics is the study of all the genes of a cell, or tissue, at the DNA (genotype), mRNA (transcriptome), or protein (proteome) levels." The
The first whole genome sequence of the Far Eastern Amur leopard is published in the open access journal Genome Biology, providing new insight into carnivory and how it impacts on genetic diversity and population size.
The first full genome sequences of two bumblebee species are published this week in the open access journal Genome Biology. They give insights into the genetic basis and evolution of important aspects of bumblebee biology ...
Through a combination of high-throughput sequencing, high performance computing, and genetic mapping, DOE JGI researchers have derived a sequence assembly for the highly repetitive plant genome of bread wheat (Triticum aestivum).
The ancestry of domesticated cattle proves more complex than previously thought, reports a paper published today in the open access journal Genome Biology. The first nuclear genome sequence from an ancient wild ox reveals ...
Scientists have developed a process that improves the efficiency of CRISPR, an up-and-coming technology used to edit DNA.
The cheetah (Acinonyx jubatus) is now at home on the African plains, but it started a migration 100, 000 years ago from North America towards its current habitat. The research, published in the open access journal Genome ...
Scientists at the University of Liverpool have carried out the first ever genome-wide survey of heritable molecular changes that regulate gene activity in wheat, in what could become a new tool to improve crop breeding technologies.
CRISPR gene-editing is allowing rapid scientific advances in many fields, including human health and now it has been shown that crop research can also benefit from this latest exciting technology.
Kansas State University scientists have released findings of a complex, two-year study of the genomic diversity of wheat that creates an important foundation for future improvements in wheat around the world.
