Article
Open AccessDynamic evolution of Panax species
Panax ginseng is one of the most valuable medicinal plants in Korea. However, deciphering its full genome sequence information for crop improvement has been hampered due to its complex genomic, genetic, and growt...

Article
Open AccessComparative FISH analysis of Senna tora tandem repeats revealed insights into the chromosome dynamics in Senna
DNA tandem repeats (TRs) are often abundant and occupy discrete regions in eukaryotic genomes. These TRs often cause or generate chromosomal rearrangements, which, in turn, drive chromosome evolution and speci...

Chapter
Molecular Cytogenetics of Panax Ginseng
While the medicinal importance of Panax ginseng has long been established, its molecular cytogenetic data have not been available until the recent decade. Slow growth, low seed yield, long seed dormancy, sensitiv...

Article
Five-color fluorescence in situ hybridization system for karyoty** of Panax ginseng
Chromosomal map** of repetitive elements is invaluable in understanding genome structure and evolution. Repetitive elements constitute ~ 80% of the allotetraploid ginseng (Panax ginseng) genome. Preparing sporo...

Chapter
Quantity, Distribution, and Evolution of Major Repeats in Brassica napus
Repetitive elements (REs) play major roles in genome organization, size, and evolution, but are often underrepresented in genome assemblies. The recent genome assembly of the allotetraploid Brassica napus genome ...
