Identification of karyotype chromosomes using nucleotide-specific fluorochromes, taking Eremurus altaicus (Asphodelaceae) as an example.

摘要

The application of different karyological methods in plants is evaluated. The resolving power and the limitations in the application of various methods of chromosome analysis in plant systematics are described. The advantage of nucleotide-specific fluorochrome staining for chromosome identification is demonstrated, taking the karyotype of Eremurus altaicus (2n = 14) as an example. This approach is seen as fruitful for studying species relationships, the origin of polyploids, and intraspecific and intrapopulational polymorphism.
