Is there any work showing a phylogenetic signal for the presence of terpenoids in plants?
Best insight from top research papers
Yes, there is evidence of a phylogenetic signal for the presence of terpenoids in plants. Studies have shown that closely related plant species tend to emit a similar number of volatile terpenes, indicating a strong phylogenetic signal in the chemical diversity of terpene blends . Additionally, a meta-analysis revealed that certain volatiles are produced by specific taxa within the microbial evolutionary tree, suggesting a phylogenetic signal in the production of these compounds . Furthermore, research on volatile isoprenoid synthases in trees has highlighted the evolutionary adaptations and genomic modifications responsible for the constitutive production of terpenoids, indicating a link between phylogeny and volatile terpene synthesis . These findings collectively support the presence of a phylogenetic signal for terpenoid presence in plants.

Shows home range size phylogenetic signal?4 answersHome range size does show a phylogenetic signal, as indicated by various studies. Tucker et al. found that body size explains a significant portion of the variation in home range size among mammalian species, with larger species occupying larger home ranges. Slavenko et al. observed that turtle home range size increases with body mass, although body mass explains relatively little of the variation. Additionally, Churchill et al. highlighted the importance of mobility costs in the activity budgets of human foragers and Neandertals, suggesting that energetics play a crucial role in determining home range size. These findings collectively support the idea that phylogenetic factors, such as body size and metabolic rates, influence the size of home ranges across different species.
How does phylogeny shapes medicinal plant uses?4 answersPhylogeny shapes medicinal plant uses by influencing the selection and distribution of plants used for medicine. Similarities in medicinal plant use across different cultures can be attributed to shared deep lineages of flowering plants and the opportunity for exchange of knowledge. Phylogenetic patterns among therapeutic applications are cross-predictive within and between cultures, suggesting limited value in targeting specific plants for specific bioactives. Phylogenetic comparative methods (PCMs) provide a framework to study the diversity of medicinal plant applications cross-culturally and infer changes in plant use over time. Medicinal plant use data mapped onto a molecular phylogeny can identify closely related species with similar medicinal uses, indicating the presence of bioactive compounds with potential biomedical value. Interpreting medicinal plant uses from a biological response perspective can reveal different phylogenetic patterns of bioactivity compared to standardized methods, allowing for a more targeted approach in drug discovery. Medicinal uses are most similar when cultures are found in similar floristic environments, highlighting the importance of adaptation to local environments in shaping traditional knowledge.
What is essential oil compound found in plant?5 answersEssential oils are complex mixtures of low molecular compounds found in various plants. These compounds include phenolics, terpenoids, acetonides, aromatic cyclic and acyclic compounds, nitrogen, and sulfur-containing compounds. The major components of essential oils are terpenes, terpenoids, and aromatic compounds, while minor components also contribute to their bioactivity. Some specific essential oil compounds found in plants include 1,8-cineole, angelylangelate, linalool, 3-methylpentylangelate, β-himachalene, and n-nonadecane. These compounds have been associated with various biological activities such as antioxidant, antimicrobial, anti-inflammatory, and anticancer effects.
What are purpose of phylogenetic tree analysis at plant?5 answersPhylogenetic tree analysis in plants serves multiple purposes. It helps in resolving the phylogenetic relationships among different plant taxa, providing insights into the evolutionary history and diversity of plants. These analyses use genome-scale data sets and gene trees to infer the relationships among species, taking into account gene duplications and losses. Phylogenetic trees also aid in understanding the evolution of reproductive systems and pollination biology, allowing for the testing of hypotheses about evolutionary transitions and the relationship of these transitions to changes in the environment. Additionally, phylogenetic trees are used to summarize the classification and evolutionary relationships of plant groups, facilitating communication and comparisons of different classifications for the same group. Overall, phylogenetic tree analysis plays a crucial role in advancing our understanding of plant evolution and taxonomy.
What are the current challenges in plant phylogenetic studies?5 answersThe current challenges in plant phylogenetic studies include the need for a roadmap for researchers to make decisions in their research design. There are also challenges related to systematic errors, such as adverse impact on orthology inference and phylogenetic reconstruction. Biological factors like whole-genome duplication, hybridization/introgression, and incomplete lineage sorting also pose challenges to phylogenetic studies. Another challenge is the selection of appropriate markers, characters, sample sizes, and reconstruction methods. In addition, the lack of consistency in phylogenetic results is attributed to inadequate modeling of changes in the substitution process. Sparse taxon sampling and the difficulty and cost of data generation are also challenges in plant phylogenetic studies.
The role of signal in speciation?4 answersStep 1:
Sexual signals play a crucial role in speciation by contributing to evolving species barriers and establishing positive genetic covariance for the Fisherian runaway process of sexual selection. The divergence of sexual signals between lineages, while remaining coordinated within lineages, is essential for the evolution of reproductive barriers and rapid speciation. Additionally, the effectiveness of mate choice signals and the divergence of communication are important factors in understanding the relative contribution of different mechanisms to the speciation process. Furthermore, the dewlap size in Anolis lizards diversifies in association with the speciation process, indicating a role for divergent selection in the macroevolution of this signaling trait.
