“…We have evidence for only two duplications in the AP3 lineage within the family, and ongoing analyses of the AG lineage show a similarly small number of recent duplications (E. M. Kramer and V. S. Di Stilio, unpublished data). In addition, phylogenetic analyses using nuclear markers have not detected any evidence of genome duplications in these taxa (Hoot 1995;Ro et al 1997). These findings appear to argue against multiple, recent genome-wide phenomena.…”

It has been proposed that the diversification of the MADS-box gene family of transcription factors has played a major role in the radiation of land plants. This suggestion is based on the critical roles that these genes play in plant development and the apparent coincidence of key duplication events with major radiations, such as the establishment of the B and C lineages concurrent with the evolution of the seed plants. On a more recent scale, it is also possible that subsequent duplication events have contributed to later morphological diversifications. In order to investigate this possibility, we are studying the evolution of homologs of the petal and stamen identity genes APETALA3 (AP3) and PISTILLATA (PI) in the Ranunculaceae. In this family, the AP3 and PI lineages have undergone many duplication events at every phylogenetic level. Early duplications gave rise to three paralogous AP3 lineages, which are found throughout the family. In contrast, numerous duplications have occurred relatively recently in the PI lineage. We outline a hypothesis that these duplications have played a role in the evolution of the unique types of petaloid organs in the Ranunculaceae and present preliminary expression data supporting such a scenario.

“…Our results agree with the previous reports from Korean populations (Lee 1967;Lee and Kim 2008). Diploidy and tetraploidy have been reported from the genus (Table 2), and the genus with R-type chromosomes is related to Anemone and recently derived in the family (Ro et al 1997).…”

“…Although generic components in a clade are contradictory, both phylogenetic studies congruently showed that Megaleranthis is most closely related to Trollius (Kim et al 2009;Wang et al 2010). To test the incongruent hypotheses, more detailed investigations applying various morphological, cytological, and molecular approaches with expanded taxon sampling is desired (e.g., Ro et al 1997;Ehrendorfer et al 2009;Wang et al 2010).…”

Chromosome numbers of 28 taxa in 10 genera of the Ranunculaceae (buttercup family) from the Korean peninsula

Somatic chromosome numbers of 28 Korean native species in the buttercup family are observed and analyzed. The plants include 10 genera with seven endemic taxa to the Korean peninsula, and most of them are the first reports from Korean populations. In particular, the chromosome numbers for the two taxa are reported for the first time: Clematis fusca var. coreana (H. Lév) Nakai (2n = 16) and Thalictrum aquilegiifolium var. sibiricum Regel & Tiling (2n = 42). The Ranunculus type chromosomes (R-type, c.3-12 μm long) are found in Megaleranthis, Actaea, Cimicifuga, Anemone, Clematis, Hepatica, and Ranunculus, whereas Aquilegia and Ranunculus have the Thalictrum type chromosomes (T-type, c.1-1.5 μm long). The two types of chromosomes in Ranunculus, one of the species-rich genera in the family (c.600 species worldwide), suggest that chromosomal differentiation plays an important role in species diversification in the genus. Evaluation of cytogenetic features in a phylogenetic frame is suggested for a better understanding of the evolutionary history of the family.

Karyotype analysis in some species of Consolida (Ranunculaceae) from Iran

et al. 2012

Consolida (dc.) S. F. Gray belongs to Ranunculaceae. The genus includes about 52 species worldwide. Here we report the diploid chromosome number and chromosome size and morphology for six Consolida species. For C. anthoroidea, C. leptocarpa, C. paradoxa and C. rugulosa the diploid chromosome number is reported for the first time. All investigated species have a diploid chromosome number of 2n = 2x = 16, except for C. persica having 2n = 2x = 14. The karyotypes of all six taxa are asymmetric, consisting of all four major chromosome types: metacentric, submetacentric, subtelocentric and telocentric chromosome type. However, considering the karyotype formula, all six species could be distinguished. In all taxa, metacentric chromosome pair 1 possesses a satellite. The only exception is C. rugulosa having an additional satellite positioned on metacentric chromosome pair 2. Karyotype data allow the separation of Aconitella from Consolida. Karyotype data plus morphological evidence support the reduction of C. paradoxa to formae level of C. rugulosa. (© 2013 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
