“…1h), and therefore we placed P. persica as sister to the clade containing A. thaliana, T. cacao, P. trichocarpa and C. follicularis. The placement of V. vinifera is also different among previously published phylogenies [52][53][54] . To account for that, two alternative tree topologies with different placements of V. vinifera were assumed in this analysis.…”

“…A maximum-likelihood tree was reconstructed using third codon position sequences of the trimAl-processed alignments, and it was subsequently reconciled with a species tree prepared from a dated large-scale plastid phylogeny of flowering plants 54 using Treefix 94 with default parameters, except with the number of iterations increased to 1,000. Although the plastid-based topology 54 is partly different from nuclear-based topology 52,53 ( Supplementary Fig. 1h), we employed it because of the necessity to include carnivorous lineages in which nuclear genome sequences are unavailable (for example, Drosera, Nepenthes and Sarracenia).…”

Genome of the pitcher plant Cephalotus reveals genetic changes associated with carnivory

Carnivorous plants exploit animals as a nutritional source and have inspired long-standing questions about the origin and evolution of carnivory-related traits. To investigate the molecular bases of carnivory, we sequenced the genome of the heterophyllous pitcher plant Cephalotus follicularis, in which we succeeded in regulating the developmental switch between carnivorous and non-carnivorous leaves. Transcriptome comparison of the two leaf types and gene repertoire analysis identified genetic changes associated with prey attraction, capture, digestion and nutrient absorption. Analysis of digestive fluid proteins from C. follicularis and three other carnivorous plants with independent carnivorous origins revealed repeated co-options of stress-responsive protein lineages coupled with convergent amino acid substitutions to acquire digestive physiology. These results imply constraints on the available routes to evolve plant carnivory.

The reproductive biology of the early-divergent genus Anaxagorea (Annonaceae), and its significance for the evolutionary development of the family

Data of six studied Neotropical Anaxagorea species are analyzed and discussed with respect to the population structure, owering phenology, ower morphology, anthesis, scent emission, thermogenesis, oral visitors, breeding system, fruit-set and seed dispersal. e probably reason for the patchy distribution of small populations of Anaxagorea species within lowland tropical forests is given. A novel explanation of the functional signi cance of ruminate endosperm is presented. Flowering of the species follows either the annual or the continuous owering pattern. All studied species have diurnal, two-day lasting, protogynous anthesis; several species have thermogenic owers. Self-compatibility appears to be the prevailing reproductive system in the genus. However, there is a strong tendency for e ecting cross-pollination. Floral scent of Anaxagorea species contains fruit-like components, and the pollinators, primarily Nitidulidae (Colopterus spp.) are attracted by deceit. Strong scenting pollination chambers occur also in most other cantharophilous Annonaceae. Novel oral developments are apparent mainly in y-, cockroach-and bee-pollinated Annonaceae, which have patterns di erent from cantharophilous species and exhibit open owers with re exed petals, which allow their pollinators to reach and touch the reproductive organs.

Ancestral traits and specializations in the flowers of the basal grade of living angiosperms

New morphological and phylogenetic data prompt us to present an updated review of floral morphology and its evolution in the basal ANITA grade of living angiosperms, Chloranthaceae, and Ceratophyllum. Floral phyllotaxis is complex whorled in Nymphaeales and spiral in Amborella and Austrobaileyales. It is unresolved whether phyllotaxis was ancestrally whorled or spiral, but if it was whorled, the whorls were trimerous. The flowers are probably ancestrally bisexual because in most families with unisexual flowers these flowers exhibit rudiments of the opposite sex. Carpels are largely ascidiate and the closure line is short, either transverse or longitudinal. A style is usually absent or, if present, generally short and not plicate. Angiospermy (carpel sealing) is by secretion, rather than postgenital fusion, except in largeflowered Nymphaeales and in Illicium, correlated with unusual fruits. Carpels with a single, median, pendent ovule are probably plesiomorphic. Chloranth aceae and Ceratophyllaceae have an unsettled phylogenetic position, but in some phylogenetic analyses they form a clade, which may be sister to the remaining mesangiosperms (Magnoliidae, monocots, eudicots). This position is supported by their carpel characters, which are similar to those of the ANITA grade and different from those of most other mesangiosperms.
