The GISH method is an improved variant of fluorescence in situ hybridization (FISH) and has been widely used in the genome analysis of various plant researches such as hybrid breeding and species evolution. The upgrading of this technology has made it one of the most important technologies in molecular cytogenetics. GISH is a molecular technique with broad application prospects that allows the differentiation of genomes in cells. Using this technique, the genomes in hybrids can be distinguished. Therefore, this method has been applied to hybrid pedigree studies, genetic improvement projects, and polyploid evolution studies. Generally, GISH is used to analyze the meiotic behavior of hybrids and polyploidies to provide information about the relationship between species. GISH technology can help decipher the genome composition of allopolyploid plants. Our service uses nuclear DNA from the genome as a template for probe design, using different nucleotide markers to distinguish them.

The development of GISH technology is also based on customized probe sets, and its core is the design and customization of characteristic probe sets. GISH assay is used in the field of plant chromosome analysis and agricultural breeding, and can realize the analysis of genomic polyploid hybrids, partial aneuploidy and recombinant inbred lines. This technique can effectively analyze the karyotypic stability of plant material and indicate the optimal genotype, thereby providing knowledge for assisted selection at different stages of crop improvement.
