  • Evaluating the Adaptive Evolutionary Convergence of Carnivorous Plant Taxa Through Functional Genomics
    Evaluating the adaptive evolutionary convergence of carnivorous plant taxa through functional genomics Gregory L. Wheeler and Bryan C. Carstens Department of Evolution, Ecology, & Organismal Biology, The Ohio State University, Columbus, OH, United States of America ABSTRACT Carnivorous plants are striking examples of evolutionary convergence, displaying complex and often highly similar adaptations despite lack of shared ancestry. Using available carnivorous plant genomes along with non-carnivorous reference taxa, this study examines the convergence of functional overrepresentation of genes previously implicated in plant carnivory. Gene Ontology (GO) coding was used to quantitatively score functional representation in these taxa, in terms of proportion of carnivory- associated functions relative to all functional sequence. Statistical analysis revealed that, in carnivorous plants as a group, only two of the 24 functions tested showed a signal of substantial overrepresentation. However, when the four carnivorous taxa were analyzed individually, 11 functions were found to be significant in at least one taxon. Though carnivorous plants collectively may show overrepresentation in functions from the predicted set, the specific functions that are overrepresented vary substantially from taxon to taxon. While it is possible that some functions serve a similar practical purpose such that one taxon does not need to utilize both to achieve the same result, it appears that there are multiple approaches for the evolution of carnivorous function in plant genomes. Our approach could be applied to tests of functional convergence in other systems provided on the availability of genomes and annotation data for a group.

  • Carnivorous Plant Responses to Resource Availability
    Carnivorous plant responses to resource availability: environmental interactions, morphology and biochemistry Christopher R. Hatcher A doctoral thesis submitted in partial fulfilment of requirements for the award of Doctor of Philosophy of Loughborough University November 2019 © by Christopher R. Hatcher (2019) Abstract Understanding how organisms respond to resources available in the environment is a fundamental goal of ecology. Resource availability controls ecological processes at all levels of organisation, from molecular characteristics of individuals to community and biosphere. Climate change and other anthropogenically driven factors are altering environmental resource availability, and likely affects ecology at all levels of organisation. It is critical, therefore, to understand the ecological impact of environmental variation at a range of spatial and temporal scales. Consequently, I bring physiological, ecological, biochemical and evolutionary research together to determine how plants respond to resource availability. In this thesis I have measured the effects of resource availability on phenotypic plasticity, intraspecific trait variation and metabolic responses of carnivorous sundew plants. Carnivorous plants are interesting model systems for a range of evolutionary and ecological questions because of their specific adaptations to attaining nutrients. They can, therefore, provide interesting perspectives on existing questions, in this case trait-environment interactions, plant strategies and plant responses to predicted future environmental scenarios. In a manipulative experiment, I measured the phenotypic plasticity of naturally shaded Drosera rotundifolia in response to disturbance mediated changes in light availability over successive growing seasons. Following selective disturbance, D. rotundifolia became more carnivorous by increasing the number of trichomes and trichome density. These plants derived more N from prey and flowered earlier.

Abstract: Cape Sundew (Drosera capensis), a carnivorous plant that catches flies with sticky mu- cus, has attracted great interest among botanists and horticulture hobbyists since the Darwin era. But little is known about how this carnivorous plant regulates morphogenesis and organ formation to accommodate environmental changes. In this article we present the relationship between gland secretion of Cape Sundew and photoperiod utilizing various physiological and morphological meth- ods. We show that Cape Sundew grows faster and secretes more mucus under long days than under short days. Under long days leaf length and the blade\petiole ratio increases, leading to increased fly catching capacities. More importantly, in the short term, the rhythm of photoperiod causes Cape Sundew to secrete mucus independent of photo intensity. Introduction As one of the most special plant groups, carnivorous plants perform photosynthesis and feed on insects and some large carnivorous plants even prey on birds and small mammals. Darwin believed that a carnivorous plant was one of the most astonishing phenomena in the world (Dar- win 1875; Ellison & Gotelli 2009). Carnivorous plants are represented by more than 600 species belonging to 20 genera (Ellison & Gotelli 2001; McPherson 2010).

Sequencing technology has improved to the point that scientists can now routinely sequence complete plastid/mitochondrial genomes and thus, vast amounts of data can be used to reconstruct phylogenies. These data are accumulating in DNA sequence repositories, such as GenBank, where everyone can benefit from the vast growth of information. The trend of generating genomic-region rich datasets has far outpaced the expasion of datasets by sampling a broader array of taxa. We show here that expanding a dataset both by increasing genomic regions and species sampled using GenBank data, despite the inherent missing DNA that comes with GenBank data, can provide a robust phylogeny for the plant order Caryophyllales (angiosperms). We also investigate the utility of trnK intron in phylogeny reconstruction at relativley deep evolutionary history (the caryophyllid order) by comparing it with rapidly evolving matK. We show that trnK intron is comparable to matK in terms of the proportion of variable sites, parsimony informative sites, the distribution of those sites among rate classes, and phylogenetic informativness across the history of the order.

We have sequenced and structurally annotated the nuclear genome of the carnivorous Roridula gorgonias and that of a non-carnivorous rela- tive, Madeira’s lily-of-the-valley-tree, Clethra arborea, both within the Ericales. This data adds an important resource to study the evolutionary genetics of plant carnivory across angiosperm lineages and also for functional and systematic aspects of plants within the Ericales. Results: Our assemblies have total lengths of 284 Mbp (R. gorgonias) and 511 Mbp (C. arborea) and show high BUSCO scores of 84.2% and 89.5%, respectively.
