Evolutionary Clock

The N-terminal 40 amino acid sequences of the small subunit of ribulose bisphosphate carboxylase have been determined for 13 species of Solanum, one other species of Solanaceae and two of Convolvulaceae. From these, and previously published sequences from Solanaceae, a minimal phylogenetic tree is derived. This agrees well with current taxonomy; the first dichotomy in the Solanaceae tree is between the two subfamilies Solanoideae and Cestroideae; within Solanum the subgenera Solanum and Leptostemonum separate dichotomously; within subgenus Leptostemonum the African and Asian species diverge from the Australian. Within the Australian species of subgenus Leptostemonum two most unusual substitutions have been noted. The implications for the hypotheses of a 'molecular evolutionary clock' and of biogeographical dispersal by continental drift are discussed.

Plant Phylogeny

N-terminal, 40 amino acid sequences of ribulose bisphosphate carboxylase small subunit are given for three species of Polygonaceae, three of Magnoliaceae and for Metasequoia. Making use of three plastocyanin and one cytochrome c sequences from the literature, these families are added to a previously published phylogenetic tree. Fagaceae and Proteaceae are also added. Uncertainties in the 14-family tree are pointed out. The root of the tree is identified using gymnosperm sequences. The concept of primitiveness as it is relevant to this research is discussed. From the phylogenetic tree there is no evidence for primitiveness of Magnoliaceae, though it is not precluded. Polygonaceae and Chenopodiaceae form a branch that diverges from the main tree near the presumptive dicotyledonous origin.
