Enzymatic activities in traps of four aquatic species of the carnivorous genus Utricularia
• Here, enzymatic activity of five hydrolases was measured fluorometrically in the fluid collected from traps of four aquatic Utricularia species and in the water in which the plants were cultured. • In empty traps, the highest activity was always exhibited by phosphatases (6.1– 29.8 μmol l − 1 h − 1 ) and β -glucosidases (1.35–2.95 μmol l − 1 h − 1 ), while the activities of α -glucosidases, β...
متن کاملResting electrical network activity in traps of the aquatic carnivorous plants of the genera Aldrovanda and Utricularia.
In this study the MEA (multielectrode array) system was used to record electrical responses of intact and halved traps, and other trap-free tissues of two aquatic carnivorous plants, Aldrovanda vesiculosa and Utricularia reflexa. They exhibit rapid trap movements and their traps contain numerous glands. Spontaneous generation of spikes with quite uniform shape, propagating across the recording ...
متن کاملSpontaneous Firings of Carnivorous Aquatic Utricularia Traps: Temporal Patterns and Mechanical Oscillations
Aquatic species of Utricularia are carnivorous plants living in environments poor in nutrients. Their trapping mechanism has fascinated generations of scientists and is still debated today. It was reported recently that Utricularia traps can fire spontaneously. We show here that these spontaneous firings follow an unexpected diversity of temporal patterns, from "metronomic" traps which fire at ...
متن کاملOxygen concentrations inside the traps of the carnivorous plants Utricularia and Genlisea (Lentibulariaceae).
BACKGROUND AND AIMS Species of Utricularia and Genlisea (Lentibulariaceae) are carnivorous, capturing small prey in traps which are physiologically very active, with abundant quadrifid and bifid glands. Traps of Utricularia have walls composed of two cell layers, and are filled with water. Diverse communities of commensal microorganisms often live inside the traps. Genlisea forms long, hollow s...
متن کاملThe smallest but fastest: ecophysiological characteristics of traps of aquatic carnivorous Utricularia.
Aquatic Utricularia species usually grow in standing, nutrient-poor humic waters. They take up all necessary nutrients either directly from the water by rootless shoots or from animal prey by traps. The traps are hollow bladders, 1-6 mm long with elastic walls and have a mobile trap door. The inner part of the trap is densely lined with quadrifid and bifid glands and these are involved in the s...
