Rootless aquatic carnivorous Utricularia exude up to 25% of their photosynthates into the trap lumen, which also harbours a complex microbial community thought to play a role in enhancing Utricularia nutrient acquisition. We investigated the composition of organic carbon in the trap fluid, its availability for microbial uptake, the influence of plant nutrient status and trap age on its biodegradability, and the composition of prokaryotic assemblages within the traps of three aquatic Utricularia…

Note Light as a factor affecting the concentration of simple organics in the traps of aquatic carnivorous Utricularia species
TLDR
The concentrations of organic compounds in the trap fluid of aquatic Utricularia are species specific, subject to rapid turnover and depend significantly on various endogenous (trap age) or exogenous factors (water chemistry, irradiance).
Hunters or farmers? Microbiome characteristics help elucidate the diet composition in an aquatic carnivorous plant
TLDR
It is concluded that Utricularia traps can, in terms of their ecophysiological function, be compared to microbial cultivators or farms, which center around complex microbial consortia acting synergistically to convert complex organic matter into a source of utilizable nutrients for the plants.
Dinitrogen fixation associated with shoots of aquatic carnivorous plants: is it ecologically important?
TLDR
It is hypothesized that the reason for limited N2 fixation in aquatic Utricularia, despite the large potential capacity, is the high concentration of NH4-N (2·0-4·3 mg L(-1)) in the trap fluid.
Ecological Traits of the Algae‐Bearing Tetrahymena utriculariae (Ciliophora) from Traps of the Aquatic Carnivorous Plant Utricularia reflexa
TLDR
This study focuses on ecological traits and life strategies of the highly abundant ciliate whose biomass by far exceeds that of other eukaryotes and bacteria independent of the trap age and proposes a revised concept of major microbial interactions in the trap fluid where ciliate bacterivory plays a central role in regeneration of nutrients bound in rapidly growing bacterial biomass.
Hunters or gardeners? Linking community structure and function of trap-associated microbes to the nutrient acquisition strategy of a carnivorous plant
TLDR
Assessment of the trap-associated microbial community structure, diversity, function, as well as the nutrient recycling potential of bacterivory gained insight into the nutrient acquisition strategies of the Utricularia hosts concluded that trap ecophysiological function is in many aspects highly analogous to that of the herbivore gut.
A comparison of photosynthetic and respiration rates in six aquatic carnivorous Utricularia species differing in morphology
The mixotrophic nature of photosynthetic plants.
TLDR
Identifying the mechanisms involved in the acquisition of organic nutrients will provide understanding of the ecological significance of mixotrophy and draw parallels between algae and plants.
A novel insight into the cost-benefit model for the evolution of botanical carnivory.
TLDR
This review summarizes results from the classical interpretation of the cost-benefit model for evolution of botanical carnivory and highlights the costs and benefits of active trapping mechanisms, including water pumping, electrical signalling and accumulation of jasmonates.

Microbial community development in the traps of aquatic Utricularia species
Utricularia carnivory revisited: plants supply photosynthetic carbon to traps.
TLDR
The importance of C exudation for the development of the microbial community associated with the traps as well as for the growth and ecology of aquatic Utricularia is discussed.
Mineral nutrient relations in the aquatic carnivorous plant Utricularia australis and its investment in carnivory
TLDR
It is suggested that shoot N content acts as a key endogenous factor regulating investment in trap biomass through a negative feedback mechanism, resulting in enhanced prey catching and, concomitantly, an increase inshoot N content.
Oxygen concentrations inside the traps of the carnivorous plants Utricularia and Genlisea (Lentibulariaceae).
TLDR
Very small or zero [O(2)], effectively anoxia, is demonstrated in Utricularia and Genlisea traps, and causes captured prey to die of suffocation.
Effect of Lake Trophic Status and Rooted Macrophytes on Community Composition and Abundance of Ammonia-Oxidizing Prokaryotes in Freshwater Sediments
TLDR
AOA are at least as numerous as AOB in freshwater sediments, and aquatic macrophytes with substantial release of oxygen and organic carbon into their rhizospheres, like L. uniflora and J. bulbosus, increase AOA abundance; AOA community composition is generally determined by lake trophy, not by plant species-specific interactions.
Tissue mineral nutrient content in turions of aquatic plants: does it represent a storage function?
TLDR
Results of a literature survey conducted for the 12 plant species revealed that mean turion nutrient content was moderately (N, P) or markedly lower than shoot or leaf nutrient content for the same 12 species.

Nutrient availability and the carnivorous habit in Utricularia vulgaris
TLDR
Investment in carnivory in U. vulgaris declined with increasing phosphorus loading and there was no effect of nutrient additions on plant growth or periphyton abundance.
Turning the Table: Plants Consume Microbes as a Source of Nutrients
TLDR
This study demonstrates that microbes enter root cells and are subsequently digested to release nitrogen that is used in shoots, providing further evidence that the autotrophy of plants has a heterotrophic constituent which could explain the presence of root-inhabiting microbes of unknown ecological function.
Diversity and Community Structure of Archaea Inhabiting the Rhizoplane of Two Contrasting Plants from an Acidic Bog
TLDR
The results of this study illustrate the general effects of roots and the specific effects of plant types on their nearby archaeal communities which in bog-inhabiting plants were mainly composed by methanogenic groups.
