Systematics and phylogeny of the Ranunculaceae — a revised family concept on the basis of molecular data
Phylogenetic trees for the Ranunculaceae based on four independent molecular data sets are compared and analyzed and congruency suggests a strong correlation between the evolution of the genes and proteins investigated and the taxa involved and further demonstrates the utility of molecular markers in plant phylogeny.
Petal evolution in Ranunculaceae
- K. Kosuge
The ontogeny of flowers in Ranunculaceae indicates a close similarity between petal and stamen primordia, and various types of nectary cup evolved independently in each phyletic group adapting to different kinds of pollinators.
Chromosomal Evolution in the Genus Brachyscome (Asteraceae, Astereae): Statistical Tests Regarding Correlation Between Changes in Karyotype and Habit Using Phylogenetic Information
The correlations between the dysploidal reduction in chromosome number and the increases in mean chromosome length, length heterogeneity and asymmetry in karyotype can be attributed to this mode of chromosomal change.
Molecular systematics of Australian Podolepis (Asteraceae: Gnaphalieae): evidence from DNA sequences of the nuclear ITS region and the chloroplast matK gene
The generic circumscription and intra-generic relationships of the genus Podolepis Labill., with various chromosome numbers from n = 12 to n = 3, were examined by sequences of the internal…
Phylogenetic relationships of some genera in the Ranunculaceae based on alcohol dehydrogenase genes
The phylogenetic analysis of T-type chromosome group clearly suggests that Coptis and Xanthoriza are a monophyletic group, and that Thalictrum with achenes were derived from Enemion and its allied genera with follicles.
Chromosome numbers and karyotypes in the Australian Gnaphalieae and Plucheeae (Asteraceae)
Chromosome number determinations from 152 collections representing 42 genera and 106 species of the Australian Gnaphalieae and Plucheeae are reported and evidence suggests that the base number is x = 14, which may be the base numbers for the entire tribe.
Chromosomal location and reorganization of the 45S and 5S rDNA in theBrachyscome lineariloba complex (Asteraceae)

- 1 March 1997
The loss or diminution of 45S r DNA sequences seem to have proceeded more rapidly than 5S rDNA sequences in the B. lineariloba complex, and the unit number of the 5 S rDNA seems to have reduced during the successive genomic additions.
Molecular Phylogeny of Rhizophoraceae Based on rbcL Gene Sequences
This cladogram for Rhizophoraceae basically agrees with those suggested by cladistic analyses based on morphological characters, except that Gynotrocheae are monophyletic with Crossostylis as a derived taxon within the tribe in the present study.
A molecular phylogeny of celtidaceae and ulmaceae (Urticales) based onrbcL Nucleotide sequences
Maximum likelihood topology among 18 trees obtained indicated that the Urticales are monophyletic with its common clade splitting basally into two: one leading to a line comprisingAmpelocera (traditionally placed in Celtidaceae) and Ulmaceae, and the other leading to the remaining genera of Celtid family, Moraceae and other Urticale.
Phylogenetic relationships of the Berberidaceae based on partial sequences of the gapA gene
The Berberidaceae is a distinctly monophyletic group, and divided into three clades: Nandina-Caulophyllum, Mahonia-Ranzania, Epimedium-Diphylleia.
