Feeding on prey increases photosynthetic efficiency in the carnivorous sundew Drosera capensis

Popis výsledku v původním jazyce

It has been suggested that the rate of net photosynthesis (AN) of carnivorous plants increases in response to prey capture and nutrient uptake; however, data confirming the benefit from carnivory in terms of increased AN are scarce and unclear. The principal aim of our study was to investigate the photosynthetic benefit from prey capture in the carnivorous sundew Drosera capensis. Red coloration of tentacles did not act as a signal to attract fruit flies onto the traps. Phosphatase, phophodiesterase andprotease activities were induced 24 h after prey capture. These activities are consistent with the depletion of phosphorus and nitrogen from digested prey and a significant increase in their content in leaf tissue after 10 weeks. Mechanical stimulationof tentacle glands alone was not sufficient to induce proteolytic activity. Activities of b-D-glucosidases and N-acetyl-b-D-glucosaminidases in the tentacle mucilage were not detected. The uptake of phosphorus from prey was more efficient
