Five major discrepancies between the S. polyrhiza cytogenetic map (clone 7498) and BioNano map (clone 9509) due to mis-assemblies or incompleteness in former studies were resolved. No clone-specific chromosome rearrangement was detected between seven tested S. polyrhiza clones after FISH with 106 BACs. Chromosome homeology and rearrangements between S. intermedia (2n = 36) and S. polyrhiza (2n = 40) were studied and revealed complex rearrangements involving 10 chromosome pairs of S. polyrhiza and 8 of S. intermedia. Alternative scenarios of karyotype evolution within the genus Spirodela are supposed. 2023-03-23T00:09:33Z 2023-03-23T00:09:33Z 2019 Dissertation https://scholar.dlu.edu.vn/thuvienso/handle/DLU123456789/115589 http://dx.doi.org/10.25673/13607 en application/pdf Martin Luther Universitat Halle Wittenberg |
