简介
- Tragopogon includes two classic examples of recently formed allopolyploid species in North America: T.ámirus and T.ámiscellus. Older Tragopogon allotetraploids from Eurasia offer ideal taxa for comparing the longer term outcomes of allopolyploidy.
- To help resolve the ancestry of one of these older polyploids, phylogenetic analyses of multiple populations of the allotetraploid T.ácastellanus (2ná=á24) and its putative diploid parents, T.ácrocifolius and T.álamottei, were conducted using sequences from nuclear (internal transcribed spacer, ITS; and alcohol dehydrogenase 1A, Adh) and plastid (trnT‐trnL spacer, trnL intron, trnL‐trnF spacer and rpl16 intron) loci. Fluorescence inásitu hybridization (FISH) and genomic inásitu hybridization (GISH) were used to investigate the chromosomal constitution of T.ácastellanus.
- Our data confirm that the widely distributed T.ácrocifolius and the Iberian endemic, T.álamottei …
