Single Virus Genomics (SVG) is a method to isolate and amplify the genomes of single virons. Viral suspensions of a mixed assemblage are sorted using flow cytometry onto a microscope slide with discrete wells containing agarose, thereby capturing the virion and reducing genome shearing during downstream processing. Whole genome amplification is achieved using multiple displacement amplification (MDA) resulting in genomic material that is suitable for sequencing.

2025
This video demonstrates a technique of zinc-finger nuclease-based genome editing in human pluripotent stem cells (hPSCs). As hPSCs can potentially be differentiated into various cell types, this technology is helpful for in vitro pathological and pharmacological studies in a patient-specific manner.

Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

Genomic Imprinting and Inheritance

Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes. The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...
FAQs
Bread wheat contains three related subgenomes, called A, B, and D. Their corresponding chromosomes and homoeologous genes may preserve similar genetic functions or carry distinct versions of traits. This structure gives researchers multiple related genetic sources to examine, but it also requires them to distinguish among subgenomes when locating genes or interpreting variation linked to plant performance.
Homoeologous genes occupy corresponding positions in the A, B, and D subgenomes. They can contain similar or different versions of genes associated with characteristics such as yield, grain quality, disease resistance, or stress tolerance. Comparing these related gene copies helps researchers determine whether a trait reflects shared genetic behavior across subgenomes or variation concentrated in one of them.
Sequencing provides the underlying genetic information, while annotation helps identify and organize relevant genes within that information. Together, these resources allow researchers to locate candidate genes, compare wheat varieties, and examine genetic variation associated with biologically important traits. The resulting genome information provides a framework for connecting inherited differences with observable differences among plants.
Researchers compare genome information from different wheat varieties to track genetic variation and investigate its relationship with traits. These comparisons can highlight differences associated with yield, grain quality, disease resistance, or tolerance of environmental stress. Such evidence helps connect biological diversity within wheat to outcomes that matter for both research and cultivar development.
A typical workflow begins with genome sequencing and annotation, followed by locating genes and comparing varieties to identify relevant genetic variation. Researchers can then use those findings in marker-assisted selection, which uses trait-associated genetic markers to guide the choice of breeding material. This approach helps focus selection on inherited features linked with desired cultivar characteristics.
Genomic information is particularly valuable when breeders seek cultivars combining several priorities, including improved yield, grain quality, disease resistance, and stress tolerance. Marker-assisted selection and genomic breeding use information about genes and genetic variation to accelerate this process. These approaches are relevant to developing wheat suited to changing climates and increasing global food demands.
