Term Definition

A group of germplasm accessions maintained for a specific purpose under defined conditions.

Comparative genomics

A research field directed to the comparison of genomes from different species in order to obtain a better understanding of the evolution of species and the location and functioning of genes.

Complementary DNA

(cDNA) In vitro generation of DNA constructed from mRNA.

Concatenated dataset

A combined dataset that connects together many individual datasets into one like links in a chain so that analyses can be done as a single unit.

Concerted evolution

A process whereby repetitive DNA families maintain one type of sequence within the repeat (become homogenized), through genetic mechanisms of unequal crossing over and gene conversion.


Agreement in results of as taxonomic analysis refers to both phenetic and cladistic results.


The management of human use of the biosphere so that it may yield the greatest sustainable benefit to current generations while maintaining its potential to meet the needs and aspirations of future generations. Thus conservation is positive embracing preservation maintenance sustainable use restoration and enhancement of the natural environment.

Conserved Orthologous Set Markers

(COS) Conservative molecular markers that are used as anchors for map development in comparative genomics studies.

Core collection

A subset of the entire germplasm collection that incorporates a representative sample of variation with a minimum of redundancy. This is an attempt to bring the entire collection to a workable size for economic or space or other constraints, and to facilitate its use, by choosing accessions that represent its most representative or useful diversity.
