The Study of Plant Phylogeny Using Amino-Acid-Sequences of Ribulose-1,5-Bisphosphate Carboxylase .VI. Some Solanum and Allied Species From Different Continents

Abstract

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.

Protogyny, Self-Incompatibility and Pollination in Anthocercis gracilis (Solanaceae)

“…The Anthocercideae are an old perhaps basal lineage in Solanaceae and present possible phytochemical links between the subfamilies Cestroideae and Solanoideae (Haegi 1979(Haegi , 1986Martin et al 1986;Symon 1991). If the Anthocercis SI system proves to be genetically homolgous to those of the better known genera, then this SI system cm!d be very ~~c i e n t in Solamceae.…”
