Confirmation of Ancient Polyploidy in Dahlia (Asteraceae) Species using Genomic In Situ Hybridization

The Choromosomal Assesment of Salt Tolerant Substituted Tritipyrum Using Genomic Fluorescentin situ Hybridization (FISH)

Genomic in situ hybridization in plants.

Genomic in situ hybridization (GISH), which is a modification of fluorescent in situ hybridization, has been widely used in the study of plants. It has become one of the most important techniques for molecular cytogenetics. GISH is a technique that allows distinguishing the genomes in a cell. With this technique, it is possible to differentiate the genomes in a hybrid; consequently, this tool h...

Genomic In Situ Hybridization in Rice

Fluorescence in situ hybridization was modified by using genomic DNAs as probes to detect wide cross somatic hybrids. The A genome was labelled and visualized as red signal while the B and C genomes were visualized as blue and green signals, respectively. This technique could distinguishly identify the hybrid SP I line with whole full sets of 6 genomes and the hybrid SP II line with some lost c...

Application of Genomic In Situ Hybridization in Horticultural Science

Molecular cytogenetic techniques, such as in situ hybridization methods, are admirable tools to analyze the genomic structure and function, chromosome constituents, recombination patterns, alien gene introgression, genome evolution, aneuploidy, and polyploidy and also genome constitution visualization and chromosome discrimination from different genomes in allopolyploids of various horticultura...

Ancient hybridization and genomic stabilization in a swordtail fish.

A rapidly increasing body of work is revealing that the genomes of distinct species often exhibit hybrid ancestry, presumably due to postspeciation hybridization between closely related species. Despite the growing number of documented cases, we still know relatively little about how genomes evolve and stabilize following hybridization, and to what extent hybridization is functionally relevant....
