DOI: 10.1038/s41598-019-39332-w
Abstract: Duckweeds are small, free-floating, largely asexual and highly neotenous organisms. They display the most rapid growth among flowering plants and are of growing interest in aquaculture and genome biology. Genomic and chromosomal data are still… read more here.

DOI: 10.1073/pnas.2219126120
Abstract: The nucleolus is the most prominent membraneless compartment within the nucleus-dedicated to the metabolism of ribosomal RNA. Nucleoli are composed of hundreds of ribosomal DNA (rDNA) repeated genes that form large chromosomal clusters, whose high… read more here.

DOI: 10.3390/biology10090844
Abstract: Simple Summary Telomeric and rDNA sequence distribution on tamarins (New world monkeys, Primates) was analysed through molecular cytogenetics by fluorescence in situ hybridization. The mapping of Telomeric and rDNA probes on chromosomes was performed in… read more here.

DOI: 10.3390/ijms23073643
Abstract: Although Crepis was the first model plant group in which chromosomal changes were considered to play an important role in speciation, their chromosome structure and evolution have been barely investigated using molecular cytogenetic methods. The… read more here.

DOI: 10.3390/ijms231911033
Abstract: The evolution of chromosome number and ribosomal DNA (rDNA) loci number and localisation were studied in Onobrychis Mill. Diploid and tetraploid species, as well as two basic chromosome numbers, x = 7 and x =… read more here.
