Secondary structure and sequence variation of the 28S rRNA gene in the Neanuridae, and its utility as a phylogenetic markerProceedings of the Xth international Colloquium on Apterygota, České Budějovice 2000: Apterygota at the Beginning of the Third Millennium

A fragment of the 28S rRNA encompassing the divergent domains D1-D5 was sequenced in 14 species of Collembola Neanuridae, 12 of which belong to the subfamily Neanurinae. A slight length variation across taxa was found in the D2, D3 and D5 divergent domains, the core regions being very conserved in length and sequence. Nucleotide composition was slightly biased towards As and Ts (55.6%), with the bias being more evident in the nucleotides not...
