    American Journal of Botany 96(1): 96–109. 2009. O NE SIZE FITS ALL? M OLECULAR EVIDENCE FOR A COMMONLY INHERITED PETAL IDENTITY PROGRAM IN RANUNCULALES 1 David A. Rasmussen, 2 Elena M. Kramer, 3 and Elizabeth A. Zimmer 4 Department of Organismic and Evolutionary Biology, Harvard University, Cambridge, Massachusetts 02138 USA Petaloid organs are a major component of the fl oral diversity observed across nearly all major clades of angiosperms. The vari- able morphology and development of these organs has led to the hypothesis that they are not homologous but, rather, have evolved multiple times. A particularly notable example of petal diversity, and potential homoplasy, is found within the order Ranunculales, exemplifi ed by families such as Ranunculaceae, Berberidaceae, and Papaveraceae. To investigate the molecular basis of petal identity in Ranunculales, we used a combination of molecular phylogenetics and gene expression analysis to characterize APETALA3 (AP3 ) and PISTILLATA (PI ) homologs from a total of 13 representative genera of the order. One of the most striking results of this study is that expression of orthologs of a single AP3 lineage is consistently petal-specifi c across both Ranunculaceae and Berberidaceae. We conclude from this fi nding that these supposedly homoplastic petals in fact share a developmental genetic program that appears to have been present in the common ancestor of the two families. We discuss the implications of this type of molecular data for long-held typological defi nitions of petals and, more broadly, the evolution of petaloid organs across the angiosperms. Key words: APETALA3 ; MADS box genes; petal evolution; PISTILLATA ; Ranunculales.

  • Morphological Evolution and Systematics of Synthyris and Besseya (Veronicaceae): a Phylogenetic Analysis
    Systematic Botany (2004), 29(3): pp. 716±736 q Copyright 2004 by the American Society of Plant Taxonomists Morphological Evolution and Systematics of Synthyris and Besseya (Veronicaceae): A Phylogenetic Analysis LARRY HUFFORD2 and MICHELLE MCMAHON1 School of Biological Sciences, Washington State University, Pullman, Washington 99164-4236 1Present address: Section of Ecology and Evolutionary Biology, Division of Biological Sciences, University of California, Davis, California 95616 2Author for correspondence ([email protected]) Communicating Editor: Wendy B. Zomlefer ABSTRACT. Phylogenetic analyses are used to examine the morphological diversity and systematics of Synthyris and Besseya. The placement of Synthyris and Besseya in Veronicaceae is strongly supported in parsimony analyses of nuclear ribosomal ITS DNA sequences. Parsimony and maximum likelihood (ML) criteria provide consistent hypotheses of clades of Synthyris and Besseya based on the ITS data. The combination of morphological characters and ITS data resolve additional clades of Synthyris and Besseya. The results show that Synthyris is paraphyletic to Besseya. In the monophyletic Synthyris clade, Besseya forms part of a Northwest clade that also includes the alpine S. canbyi, S. dissecta,andS. lanuginosa and mesic forest S. cordata, S. reniformis, S. platycarpa,andS. schizantha. The Northwest clade is the sister of S. borealis. An Intermountain clade, comprising S. ranunculina, S. laciniata, S. pinnati®da,andS. missurica, is the sister to the rest of the Synthyris clade. Constraint topologies are used to test prior hypotheses of relationships and morphological similarities. Parametric bootstrapping is used to compare the likelihood values of the best trees obtained in searches under constraints to that of the best tree found without constraints.

Irrever- sible loss of stem rigidity was mediated by disruption, separation and eventual loss of primary phloem fibres via secondary growth of the periderm and cambial activity. Each species showed variations of non-self-supporting mechanical architecture relating to specific habitat preferences. In aerial stems of C. recta the structural Young’s modulus remained approximately constant during ontogeny, a mechanical signal characteristic for semi-self-supporting architectures. •Woody aerial plant stems are extremely rare in the Ranunculaceae and seldom, if ever, show self-supporting characteristics.
