PANOMICS meets germplasm

Switchgrass Germplasm Resources

Switchgrass (Panicum virgatum L.) is an important native grass and dominant member of the tallgrass prairie ecosystem. It is used for conservation, restoration, livestock feed production, and bioenergy feedstock production. The purpose of this review is to describe the biological and geographical basis for switchgrass germplasm diversity and to provide a resource for scientists and outreach per...

Cereal germplasm resources.

The role of cereal germplasm banks is to collect, maintain, preserve, and distribute seeds representing the genetic diversity of crop species. While germplasm resources have traditionally been used in breeding efforts to improve a crop plant, they have also proved useful in both applied and basic research efforts to give insight into the biology of a crop plant (Harlan, 1975; Hyland, 1977; Spra...

Breeding: Incorporation of Exotic Germplasm

Exotic germplasm refers to crop varieties unadapted to a breeder’s target environment, and is an important resource for crop improvement. Because genetic diversity within elite cultivars of a crop is limited compared to the variability within the species and its relatives worldwide, genes from exotic germplasm can protect the crop against new biotic and abiotic stresses, and may represent uniqu...

Embryo manipulation of the germplasm.

The development of the avian embryo is used to demonstrate the potential for future advances in genomic strategies. A mathematical model is derived to indicate the most useful approaches for using chimeras to access the chicken genome. A review of the way that germ cells are processed through the gonad highlights the need for such an analysis of cell kinetics and indicates that the right rudime...
