GISH: Resolving Interspecific and Intergeneric Hybrids

  • Nathalie Piperidis
Part of the Methods in Molecular Biology book series (MIMB, volume 1115)


Genomic in situ hybridization (GISH) is an invaluable cytogenetic technique which enables the visualization of whole genomes in hybrids and polyploidy taxa. Total genomic DNA from one or two different species/genome is used as a probe, labeled with a fluorochrome and directly detected on mitotic chromosomes from root-tip meristems. In sugarcane we were able to characterize interspecific hybrids of two closely related species as well as intergeneric hybrids of two closely related genera.
