Introduction
Stefan Wanke currently works at the Institute of Botany, Technische Universität Dresden, Germany. Stefan does research in Plant Sciences especially focusing on three disciplines: (1) traditional systematics including all of its facets, as the ultimate basis for plant evolutionary and ecological research, (2) molecular methods from the development and evaluation to application, including state-of-art ‘-omics’ technologies, and (3) the combination of the aforementioned disciplines with experimental ecological research questions such as in pollination biology or biomechanics. Current projects range from basic science in evolutionary biology to applied science (plant breeding).

Article
Full-text available
Plastid genomes of photosynthetic flowering plants are usually highly conserved in both structure and gene content. However, the plastomes of parasitic and mycoheterotrophic plants may be released from selective constraint due to the reduction or loss of photosynthetic ability. Here we present the greatly reduced and highly divergent, yet functiona...

Full-text available
Identifying orthologous molecular markers that potentially resolve relationships at and below species level has been a major challenge in molecular phylogenetics over the past decade. Non-coding regions of nuclear low- or single-copy markers are a vast and promising source of data providing information for shallow-scale phylogenetics. Taking advant...

Full-text available
Amborella trichopoda is strongly supported as the single living species of the sister lineage to all other extant flowering plants, providing a unique reference for inferring the genome content and structure of the most recent common ancestor (MRCA) of living angiosperms. Sequencing the Amborella genome, we identified an ancient genome duplication...
Article
Full-text available
Pollination of several angiosperms is based on deceit. In such systems, the flowers advertise a reward that ultimately is not provided. We report on a previously unknown pollination/mimicry system discovered in deceptive Aristolochia rotunda (Aristolochiaceae). Pollinators were collected in the natural habitat and identified. Flower scent and the v...
Article
Full-text available
Extreme haustorial parasites have long captured the interest of naturalists and scientists with their greatly reduced and highly specialized morphology. Along with the reduction or loss of photosynthesis, the plastid genome often decays as photosynthetic genes are released from selective constraint. This makes it challenging to use traditional plas...

Deceptive flowers decoy pollinators by advertising a reward, which finally is not provided. Numerous deceptive plants are pollinated by Diptera, but the attractive cues and deceptive strategies are only identified in a few cases. A typical fly-deceptive plant genus is Aristolochia , which evolved sophisticated trap flowers to temporarily capture po...

The mega-diversity of herbivorous insects is attributed to their co-evolutionary associations with plants. Despite abundant studies on insect-plant interactions, we do not know whether host-plant shifts have impacted both genomic adaptation and species diversification over geological times. We show that the antagonistic insect-plant interaction bet...
Article
Photoredox catalysis is a powerful and modern strategy for the synthesis of complex organic molecules. So far, this field has relied on the use on a limited range of metal-based chromophores or artificial organic dyes. Here, we show that the ubiquitous plant genus Hypericum can be used as efficient photoredox catalyst. The dried blossoms efficientl...

The exuberant proliferation of herbivorous insects is attributed to their associations with plants. Despite abundant studies on insect-plant interactions, we do not know whether host-plant shifts have impacted both genomic adaptation and species diversification over geological times. We show that the antagonistic insect-plant interaction between sw...
Article
Controlled spatio‐temporal cell division and expansion are responsible for floral bilateral symmetry. Genetic studies have pointed to class II TCP genes as major regulators of cell division and floral patterning in model core eudicots. Here we study their evolution in perianth‐bearing Piperales and their expression in Aristolochia, a rare occurrenc...
Article
Full-text available
Plastomes of parasitic and mycoheterotrophic plants show different degrees of reduction depending on the plants’ level of heterotrophy and host dependence in comparison to photoautotrophic sister species, and the amount of time since heterotrophic dependence was established. In all but the most recent heterotrophic lineages, this reduction involves...

1 2 The grapevine, Vitis vinifera L., is one of the major fruit crops in the world. Breeding new grapevine cultivars for wine production with specific characteristics is a time consuming and costly process. While there are selection markers for resistance, so far, there are none for 'wine quality' since this is characterized by a highly complex com...
Article
Gaps between molecular ages and fossils undermine the validity of time-calibrated molecular phylogenies. An example of the time gap surrounds the age of angiosperms' origin. We calculate molecular ages of the earliest flowering plant lineages using 22 fossil calibrations (101 genera, 40 families). Our results reveal the origin of angiosperms at the...
