Utilization of plant resources in the

Plant Genet Res Distribution of germplasm is primarily through requests that are received through web access to GRIN. Phylloxera resistant grape rootstocks and hybrids derived from North American wild germplasm were instrumental in rescuing the European wine industry.

Activities will be intensified to obtain wild and weedy relatives from other genebanks. Develop diagnostic SNP markers for four wild tomato species.

The primary goal of the research has been to describe intra- and interspecific genomic variation and to define genetic relationships among individuals, populations, and species. Most crops of commercial significance in the northeastern U.

With the actual or potential loss of some of our most effective herbicides, fungicides, and insecticides, the need for novel sources of resistance or tolerance genes will increase. Significant progress in characterizing genetic diversity patterns and phylogeny studies of grapes has been made in last few years by using molecular markers Myles et al.

More importantly, productivity, profitability and viability of agriculture in the northeast will be ensured as a result of the secured and well-characterized germplasm preserved at PGRU.

Development of new core subsets and refinement of existing core subsets for major crops. A new grapevine virus discovered by deep sequencing of virus- and viroid-derived small RNAs in Cv Pinot gris.

In situ resource utilization

A major effort is also underway at the PGRU to produce digital images of all crops at various stages of development to show their characteristics. Genetic diversity of wild Malus orientalis from Turkey and Southern Russia. Collection trips for other native North American Vitis species are planned.

Capacity Utilization Rate

Of the 47 markers surveyed, four were involved in linkage drag on chromosome 9 during introgression breeding, while alleles at five markers originated from natural hybridization with S. For example, germplasm of tomato has been used extensively for resistance to pests and diseases and genes from the apple collection have been used for resistance to apple scab, fire blight, blue mold, bitter rot, superficial scald, wooly apple aphids and drought.

It consists of two applications: Many northeastern State Agricultural Experiment Stations SAESs have research and extension responsibilities for these valuable commodities and access to critical germplasm resources is essential for progress in research and crop improvement of these crops.

Genome-wide genetic marker discovery and genotyping using next-generation sequencing. This information is useful to grape breeders in North America due to the impact of global warming and reduction in winter chilling accumulation White et al.

The PGRU distributes germplasm in six different forms: The SSR marker data were used to determine the genetic diversity of wild Malus species, identify accessions that represent the genetic diversity of the wild populations and select them for the permanent collection and possibly the Malus core, identify duplicated accessions, provide new sources of traits of interest such as disease resistance Forsline et al.

This will prove useful to meet the changes in environmental conditions that the world now faces. It also supports the major efforts in screening for high-priority traits, such as important disease and pest resistances and traits important to human health, much of which is done in collaboration with scientists from SAES within this region.

More rapid movement of germplasm through the quarantine system needs to be encouraged by the PGRU, for both seed and clonal crops. We will complete the evaluation of nitrogen-containing bioactive components in the tomato core collection accessions by providing cryogenically prepared samples to our collaborator A.

The core set serves as a representative sample of broad phenotypic and genotypic diversity available in PGRU tomato germplasm. Recent progress using high-throughput sequencing technologies in plant molecular breeding. Engineering definition[ edit ] One is the "engineering" or "technical" definition, according to which potential output represents the maximum amount of output that can be produced in the short-run with the existent stock of capital.

Accessions, inventory, order, and characterization data are continually updated to provide the most current PGRU information possible. Because of the increasing importance of heirlooms for crop improvement for breeding for organic production, we will add improved varieties for organic production.

Again, the time series show more or less the same historical movement.The federal agency ARS, through acquisition, maintenance, characterization, documentation, and distribution activities, will make plant genetic resources available for evaluation and utilization research. Plant Genetic Resources is an international journal that brings together the many diverse topics concerned with plant genetic resources.

Each issue gives you access to peer-reviewed research papers on genetic variation in plants, both crop and non-crop, as well as on the technical, socio-economic, legal and geo-political aspects of PGR.

The importance of plant genetic resources (PRG) has been highlighted time and again for the future safety of mankind. There is a great urgency to have new technologies that can conserve and characterize the collections and dramatically increase the spectrum of conserved species.

Statement of Issues and Justification

In space exploration, in situ resource utilization (ISRU) is defined as "the collection, processing, storing and use of materials encountered in the course of human or robotic space exploration that replace materials that would otherwise be brought from Earth." ISRU is the practice of leveraging resources found or manufactured on other astronomical objects (the Moon, Mars, asteroids, etc.) to.
