Genomic in situ hybridization in plants

G. S. Silva and Souza, M. M., Genomic in situ hybridization in plants, vol. 12. pp. 2953-2965, 2013.

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 has been applied to the study of hybrid lineages, genetic improvement programs, and studies of the evolution of polyploids.
