Abstract Phylogenetic analyses of sequences the nuc rDNA small subunit (18S), internal transcribed spacer (ITS1-5.8S-ITS2 = ITS), and large (28S) region (= 18S-ITS-28S), as well this concatenated with largest RNA polymerase II ( RPB1 ) gene, proved that species originally described Acaulospora polonica (phylum Glomeromycota represents a new genus family ancient order Archaeosporales, here intro...
Nuclear DNA sequence data are essential for obtaining a complete understanding of plant species relationships, yet these data have been conspicuously absent from phylogenetic analyses of Lemnaceae (duckweeds). Using a modified Sanger sequencing protocol, we obtained DNA sequences of duckweed nuclear ribosomal regions, including 18S and 26S rDNA genes, the external transcribed spacer (ETS) and t...
