Crop brassicas include three diploid [ Brassica rapa (AA; 2 n = 2 x = 16), B. nigra (BB; 2 n = 2 x = 18), and B. oleracea (CC; 2 n = 2 x = 20)] and three derived allotetraploid species. It is difficult to distinguish Brassica chromosomes as they are small and morphologically similar. We aimed to develop a genome-sequence based cytogenetic toolkit f...

BackgroundMeiosis of newly formed allopolyploids frequently encounter perturbations induced by the merging of divergent and hybridizable genomes. However, to date, the meiotic properties of allopolyploids with dysploid parental karyotypes have not been studied in detail. The allotetraploid Cucumis ×hytivus (HHCC, 2n = 38) was obtained from interspe...

Chromosome research : an international journal on the molecular, supramolecular and evolutionary aspects of chromosome biology
Fluorescence in situ hybridization (FISH) was developed more than 30 years ago and has been the most paradigm-changing technique in cytogenetic research. FISH has been used to answer questions related to structure, mutation, and evolution of not only individual chromosomes but also entire genomes. FISH has served as an important tool for chromosome...

Dioecious species accounted for 6% of all plant species, including a number of crops and economically important species, such as poplar. However, sex determination and sex chromosome evolution have been studied only in few dioecious species. In poplar, the sex-determining locus was mapped to chromosome 19. Interestingly, this locus was mapped to ei...
