Differential amplification of satellite PaB6 in chromosomally hypervariable Prospero autumnale complex (Hyacinthaceae)

Original language description

Chromosomal evolution, including numerical and structural changes, is a major force in plant diversification and speciation. This study addresses genomic changes associated with the extensive chromosomal variation of the Mediterranean Prospero autumnalecomplex (Hyacinthaceae), which includes four diploid cytotypes each with a unique combination of chromosome number (x = 5, 6, 7), rDNA loci and genome size. Although present in all Prospero species, PaB6 has undergone differential amplification only in chromosomally variable P. autumnale, particularly in cytotypes B6B6 and B5B5. These arose via independent chromosomal fusions from x = 7 to x = 6 and 5, respectively, accompanied by genome size increases. The copy numbers of satellite DNA PaB6 are among the highest in angiosperms, and changes of PaB6 are exceptionally dynamic in this group of closely related cytotypes of a single species.
