Chromosome Painting in Marsupials.
To generate a model of mammalian karyotype evolution and to extend our knowledge of the evolutionary relationships of mammals, it is helpful to deduce ancestral chromosomal arrangements. Of particular interest would be a global comparison among the 3 major extant groups of mammals, since this would reveal the most ancient arrangements of the mammalian genome and allow us to follow chromosomal r...
متن کاملChromosome painting using repetitive DNA sequences as probes for somatic chromosome identification in maize.
Study of the maize (Zea mays L.) somatic chromosomes (2n = 20) has been difficult because of a lack of distinguishing characteristics. To identify all maize chromosomes, a multicolor fluorescence in situ hybridization procedure was developed. The procedure uses tandemly repeated DNA sequences to generate a distinctive banding pattern for each of the 10 chromosomes. Fluorescence in situ hybridiz...
متن کاملChromosome painting: a useful art.
Chromosome 'painting' refers to the hybridization of fluorescently labeled chromosome-specific, composite probe pools to cytological preparations. Chromosome painting allows the visualization of individual chromosomes in metaphase or interphase cells and the identification of both numerical and structural chromosomal aberrations in human pathology with high sensitivity and specificity. In addit...
متن کاملA new chromosome was born: comparative chromosome painting in Boechera.
Comparative chromosome painting is a powerful tool to study the evolution of chromosomes and genomes. Analyzing karyotype evolution in cruciferous plants highlights the origin of aberrant chromosomes in apomictic Boechera and further establishes the cruciferous plants as important model system for our understanding of plant chromosome and genome evolution.
متن کاملComparative chromosome painting in Carnivora and Pholidota.
The order of Carnivora has been very well characterized with over 50 species analyzed by chromosome painting and with painting probe sets made for 9 Carnivora species. Representatives of almost all families have been studied with few exceptions (Otariidae, Odobenidae, Nandiniidae, Prionodontidae). The patterns of chromosome evolution in Carnivora are discussed here. Overall, many Carnivora spec...
