Genomic relationships among diploid and polyploid species of the genus Eryngium L. using genomic in situ hybridization
Eryngium L. (Umbelliferae) is a large genus including more than 250 species worldwide. The large morphological variability in this genus makes it difficult to delimit the species or to establish phylogenetic relationships. The occurrence of different ploidy levels within the genus might indicate a h...

We compare the genomes of the diploids E. horridum and E. eburneum, the tetraploids E. megapotamicum and E. regnellii, and the hexaploids E. pandanifolium (as a representative of the whole pandanifolium complex) and E. paniculatum using genomic in situ hybridization (GISH).

Eryngium horridum and E. eburneum do not seem to be the direct progenitors of the polyploids analyzed. On the other hand, it seems that other diploid species unrelated to E. horridum and E. eburneum are involved in their origin. Our results are consistent with morphological and phylogenetic studies, indicating a close relationship between the species of the series Latifolia. Fil:Perthuy, G.Y. Universidad de Buenos Aires.

Eryngium L. (Umbelliferae) is a large genus including more than 250 species worldwide. The large morphological variability in this genus makes it difficult to delimit the species or to establish phylogenetic relationships.

In the present study, the chromosome number and karyotype of E. regnellii are reported for the first time and the ploidy level of a population of E. paniculatum is confirmed. We compare the genomes of the diploids E. horridum and E. eburneum, the tetraploids E. megapotamicum and E. regnellii, and the hexaploids E. pandanifolium (as a representative of the whole pandanifolium complex) and E. paniculatum using genomic in situ hybridization (GISH).
