Carnivorous Nutrition in Pitcher Plants (Nepenthes spp.) via an Unusual Complement of Endogenous Enzymes.
Plants belonging to the genus Nepenthes are carnivorous, using specialized pitfall traps called "pitchers" that attract, capture, and digest insects as a primary source of nutrients. We have used RNA sequencing to generate a cDNA library from the Nepenthes pitchers and applied it to mass spectrometry-based identification of the enzymes secreted into the pitcher fluid using a nonspecific digesti...
متن کاملNepenthesin Protease Activity Indicates Digestive Fluid Dynamics in Carnivorous Nepenthes Plants
Carnivorous plants use different morphological features to attract, trap and digest prey, mainly insects. Plants from the genus Nepenthes possess specialized leaves called pitchers that function as pitfall-traps. These pitchers are filled with a digestive fluid that is generated by the plants themselves. In order to digest caught prey in their pitchers, Nepenthes plants produce various hydrolyt...
متن کاملIsolation and characterization of chitinase genes from pitchers of the carnivorous plant Nepenthes khasiana.
The genus Nepenthes represents carnivorous plants with pitcher traps capable of efficient prey capture and digestion. The possible involvement of plant chitinases in this process was studied in Nepenthes khasiana. Two different types of endochitinases were identified in the liquid of closed traps exhibiting substrate specificity for either long chitin polymers or N-acetylglucosamine (GlcNAc) ol...
متن کاملEffect of pitcher age on trapping efficiency and natural prey capture in carnivorous Nepenthes rafflesiana plants.
BACKGROUND AND AIMS Nepenthes pitchers are sophisticated traps that employ a variety of mechanisms to attract, capture and retain prey. The underlying morphological structures and physiological processes are subject to change over the lifetime of a pitcher. Here an investigation was carried out on how pitcher properties and capture efficiency change over the first 2 weeks after pitcher opening....

Figure 1. Carnivorous plants. When we chew and then swallow meat, we stimulate glands (pancreatic acinar cells) to secrete hydrochloric acid and proteases. Amino acids released into the human stomach by the acidic lytic sap are forwarded to and taken up by the intestine. When compared with the human endocrine system, the Venus flytrap also operates as a mouth, stomach and intestine, all combine...
