Study of Reticulation (Polyploidy/Hybridisation) by Fluorescence in situ hybridisation (FISH) (CAT#: STEM-MB-1229-WXH)

Introduction

The convergence of distinct lineages upon interspecific hybridisation, including when accompanied by increases in ploidy (allopolyploidy), is a driving force in the origin of many plant species. In plant breeding too, both interspecific hybridisation and allopolyploidy are important because they facilitate introgression of alien DNA into breeding lines enabling the introduction of novel characters.
Fluorescence in situ hybridisation (FISH) have been applied to: 1) studies of interspecific hybridisation and polyploidy in nature, 2) analyses of phylogenetic relationships between species, 3) genetic mapping and 4) analysis of plant breeding materials.
