Si. Komarnitsky et al., MOLECULAR PHYLOGENY OF THE NUCLEAR 5.8S RIBOSOMAL-RNA GENES IN 37 SPECIES OF NICOTIANA GENUS, Genetika, 34(7), 1998, pp. 883-889
The primary structure of the 5.8S rRNA gene was established in 37 spec
ies of the genus Nicotiana representing four different sections of the
subgenus Petuniodes: Acuminatae, Alatae, Noctiflorae, and Suaveolente
s. On the basis of these data, phylogenetic analysis was performed. Th
e obtained results are in good agreement with the modem systematics of
the genus. However, the bootstrap analysis gaves only poor statistica
l support for the branches of the phylogenetic tree owing to a small n
umber of phylogenetically informative positions.
