Most plants grow and develop by taking up nutrients from the soil while continuously under threat foraging animals. Carnivorous have turned tables capturing consuming nutrient-rich animal prey, enabling them to thrive in nutrient-poor soil. To better understand evolution of botanical carnivory, we compared draft genome Venus flytrap (Dionaea muscipula) with that its aquatic sister, waterwheel plant Aldrovanda vesiculosa, sundew Drosera spatulata. We identified an early whole-genome...
• The mineral nutrition of terrestrial carnivorous plants was investigated under glasshouse conditions to elucidate ecophysiological adaptations this plant group. In Drosera capillaris and D. capensis, absorption N, P, K, Mg from insects relatively efficient (> 43%), whereas that Ca not. Carnivorous (D. peltata, scorpioides, Dionaea muscipula) exhibited a high efficiency re-utilization N (70–82%), P (51–92%), K (41–99%) senescing leaves. Re-utilization low or negative, highly negative....
• Here, enzymatic activity of five hydrolases was measured fluorometrically in the fluid collected from traps four aquatic Utricularia species and water which plants were cultured. In empty traps, highest always exhibited by phosphatases (6.1–29.8 µmol l−1 h−1) β-glucosidases (1.35–2.95 h−1), while activities α-glucosidases, β-hexosaminidases aminopeptidases usually lower one or two orders magnitude. Two days after addition prey (Chydorus sp.), all noticeably decreased foliosa U. australis...
Abstract: A new ELF (enzyme labelled fluorescence) assay was applied to detect phosphatase activity in glandular structures of 47 carnivorous plant species, especially Lentibulariaceae, order understand their digestive activities. We address the following questions: (1) Are phosphatases produced by plants and/or inhabitants traps? (2) Which type hairs/glands is involved production phosphatases? (3) Is this a common feature among or it restricted evolutionarily advanced species? Our results...
Abstract: In aquatic species of carnivorous Utricularia, about 10—50% the total biomass consists bladders. Utricularia bladders are physiologically very active organs though their chlorophyll content may greatly be reduced. To specify energetic costs carnivory, respiration (RD) and net photosynthetic rate (PN) were compared in leaves or shoot segments six with differentiated (U. ochroleuca, U. intermedia, floridana) non‐differentiated shoots vulgaris, australis, bremii) under optimum...
The fast motion of the snap-traps terrestrial Venus flytrap ( Dionaea muscipula ) have been intensively studied, in contrast to tenfold faster underwater its phylogenetic sister, waterwheel plant Aldrovanda vesiculosa ). Based on biomechanical and functional–morphological analyses a reverse biomimetic approach via mechanical modelling computer simulations, we identify combination hydraulic turgor change release prestress stored trap as essential for actuation. Our study is first analyse...
Utricularia multifida and U. westonii are Australian species classed recently with the subgenus Polypompholyx, which is comprised of most evolutionary basal species. Their traps bear all functional structures necessary for negative pressure generation suction ('firing'), i.e., active prey catching, but from tissue-culture-raised plants not known to fire. However, presumably, in situ active. Traps terrestrial both raised tissue culture were used measurement critical further elucidate whether...
The evolution of intracellular endosymbiosis marks a major transition in the biology host and endosymbiont. Yet, how adaptation manifests genomes participants remains relatively understudied. We investigated this question by sequencing Tetrahymena utriculariae, commensal aquatic carnivorous bladderwort Utricularia reflexa, its algae, Micractinium tetrahymenae. discovered an expansion copy number negative selection TLD domain-bearing gene family genome T. identifying it as candidate for being...
Background and AimsSpecies of Utricularia Genlisea (Lentibulariaceae) are carnivorous, capturing small prey in traps which physiologically very active, with abundant quadrifid bifid glands. Traps have walls composed two cell layers, filled water. Diverse communities commensal microorganisms often live inside the traps. forms long, hollow subterranean foliar origin, growing anoxic wet substrate. Knowledge O2 concentrations is vital for understanding their physiological functioning conditions...
Identification of tradeoffs among physiological and morphological traits their use in cost–benefit models ecological or evolutionary optimization arguments have been hallmarks analysis for at least 50 years. Carnivorous plants are model systems studying a wide range ecophysiological processes the application evolution carnivory by has provided many novel insights into trait‐based models. Central to botanical is relationship between nutrients photosynthesis; primary interest how carnivorous...
It has been suggested that the rate of net photosynthesis (AN) carnivorous plants increases in response to prey capture and nutrient uptake; however, data confirming benefit from carnivory terms increased AN are scarce unclear. The principal aim our study was investigate photosynthetic sundew Drosera capensis. Prey attraction experiments were performed, with measurements visualization enzyme activities, elemental analysis pigment quantification together simultaneous gas exchange chlorophyll...
Carnivorous plants are an ecological group of approx. 810 vascular species which capture and digest animal prey, absorb prey-derived nutrients utilize them to enhance their growth development. Extant carnivorous have evolved in at least ten independent lineages, adaptive traits represent example structural functional convergence. Plant carnivory is a result complex adaptations mostly nutrient-poor, wet sunny habitats when the benefits exceed costs. With boost interest extensive research...
Abstract Turions are vegetative, dormant, and storage overwintering organs formed in perennial aquatic plants response to unfavorable ecological conditions originate by extreme condensation of apical shoot segments. The contents cytokinins, auxins, abscisic acid were estimated apices summer growing, rootless carnivorous plants, Aldrovanda vesiculosa Utricularia australis , developing turions at three stages full maturity reveal hormonal patterns responsible for turion development. hormones...
Species of the carnivorous family Lentibulariaceae exhibit smallest genomes in flowering plants. We explored hypothesis that their minute result from unique mitochondrial cytochrome c oxidase (COX) mutation. The mutation may boost efficiency, which is especially useful for suction-bladder traps Utricularia, but also increase DNA-damaging reactive oxygen species, leading to genome shrinkage through deletion-biased DNA repair. aimed explore this mutation's impact on size, providing insights...
The rootless, aquatic Utricularia species belong to the largest and most cosmopolitan carnivorous plant genus. Populations of plants are an important component many standing, nutrient-poor, humic waters. Carbon (C) allocation is aspect Utricularia's ecophysiology that has not been studied previously there considerable uncertainty about functional ecological benefit trap-associated microbial community potential role played by C exudation in enhancing plant-microbe interactions. A...
Low temperature is considered the main limiting factor for plant growth and nutrient supply at high elevations. It has been repeatedly reported that an increase in foliar contents occurs with elevation which interpreted as plants' inability to use absorbed resources growth. However, although large data sets from various mountainous regions are available, elevations exceeding 5000 m rare, leaving uncertainties on relevance of these patterns under extreme alpine conditions. To fill this gap,...
