“…Our analyses also reveal enrichment patterns for GO terms connected with photosynthesis and respiration (i.e., GO:0016168, GO:0046933, GO:0009768). Producing the morphology and molecules that allow carnivory (i.e., pigment to attract insects or traps to catch them) is energetically demanding, and carnivory impacts both respiration and photosynthesis (Adamec et al, 2021;Pavlovič, 2022). Indeed, trap development and activity are generally accompanied by spatio-temporal activation of respiration and inactivation of photosynthesis.…”

Phenotypic convergence is found across the tree of life, and morphological similarities in distantly related species are often presumed to have evolved independently. However, clarifying the origins of traits has recently highlighted the complex nature of evolution, as apparent convergent features often share similar genetic foundations. Hence, the tree topology of genes that underlie such traits frequently conflicts with the overall history of species relationships. This conflict creates both a challenge for systematists and an exciting opportunity to investigate the rich, complex network of information that connects molecular trajectories with trait evolution. Here we probe the evolutionary history of pleisiomorphic features in the carnivorous Caryophyllales, a charismatic group of flowering plants. Using a novel conflict identification program named CAnDI (Conflict And Duplication Identifier), we dissect all gene relationships within homolog trees and find genomic evidence that the molecular basis of mucilaginous sticky traps was likely present in the ancestor of all carnivorous Caryophyllales. We also show that many genes whose evolutionary trajectories group species with similar trap devices code for proteins contributing to plant carnivory and identify aLATERAL ORGAN BOUNDARY DOMAINgene as a possible regulator of sticky trap development. Our results demonstrate that analysing conflict on homolog trees, rather than pre-identified orthologs, can aid in uncovering the genetic basis of trait evolution.

“…Plants evolved various strategies (mycorrhiza, myrmecophily, symbiosis with nitrogen-fixing bacteria) to live in nutrient-poor habitats, and carnivory is an example of such adaptation. Macroelements are absorbed from the bodies of captured organisms; however, carnivorous species also perform photosynthesis and assimilate carbon dioxide using the C3 pathway, thus, can be considered as mixotrophic [5]. When Charles Darwin (1875) published his book about carnivorous plants, he used the word "insectivorous".…”

“…Animal feces are a source of macroelements [10,11]. Another strategy occurs in N. ampullaria, which collects in pitchers the plant-derived materials and benefits from this material utilization [5]. This "vegetarian" trend also occurs in Utricularia and Genlisea, which capture and digest algae in addition to animal prey [12,13].…”

Biological Potential of Carnivorous Plants from Nepenthales

Since Charles Darwin and his book carnivorous plants have aroused interest and heated debate. In addition, there is growing interest in this group of plants as a source of secondary metabolites and in the application of their biological activity. The aim of this study was to trace the recent literature in search of the application of extracts obtained from families Droseraceae, Nepenthaceae, and Drosophyllaceae to show their biological potential. The data collected in the review clearly indicate that the studied Nepenthales species have great biological potential in terms of antibacterial, antifungal, antioxidant, anti-inflammatory, and anticancer use. We proposed that further investigations should include: (i) bioactivity-guided investigations of crude plant extract to connect a particular type of action with a specific compound or a group of metabolites; (ii) a search for new bioactive properties of carnivorous plants; (iii) establishment of molecular mechanisms associated with specific activity. Furthermore, further research should be extended to include less explored species, i.e., Drosophyllum lusitanicum and especially Aldrovanda vesiculosa.

Carnivorous plants obtain nutrients from arthropod prey (carnivory) and their environment. However, little is known about the seasonal diet shifts between carnivory versus environment nutrient acquisition among co‐occurring carnivorous plant species. Although studies reporting captured prey species for carnivorous plants are abundant, studies investigating the composition of assimilated prey species are scarce. Here, we report spatiotemporal dynamics in carnivory versus environmental nutrient acquisition and compositional analysis of assimilated prey species for carnivorous plants of New England (USA). We measured the natural abundance stable isotope ratios of aquatic Utricularia inflata (Lentibulariaceae), terrestrial Sarracenia purpurea (Sarraceniaceae) and Drosera intermedia (Droseraceae) and their nutrient sources during their growing season in two oligotrophic ponds in New England (USA). MixSIAR, a Bayesian stable isotope mixing model, was used to estimate the extent of carnivory for each plant species and the composition of prey species assimilated in terrestrial carnivorous plants. Aquatic U. inflata acquired more nutrients from carnivory (c. 70%–100%) than terrestrial species (c. 30–60%). Sarracenia purpurea acquired nutrients mainly from Formicidae. The nutrient sources for D. intermedia varied spatiotemporally between arthropod species. The large contribution of carnivory to the nutrient budget of U. inflata could be due to its lack of roots and high metabolism. Sarracenia purpurea and D. intermedia could benefit from dissolved organic nitrogen in the environment. Our findings on prey compositions can be used as the first available prior information for the Bayesian approach in future studies. Understanding the sources of nutrients in carnivorous plants provides invaluable insight into their ecophysiology and may inform the conservation of their fragile wetland ecosystems.
