FISHy Analysis of Tetraploid Cotton Species

Fluorescent in situ hybridization(FISH) is an important technique in plant genome research,because it provides integrated information about DNA,chromosomes and genomes.Genomic in situ hybridization(GISH) is a modification of FISH that can be used to rapidly compare genome content,relatedness,organization and/or behavior.GISH results often provide insight into genome evolution and species relationships.The cotton genus Gossypium consists of about 50 species,including 5
