Optimalisation of expression conditions for production of round-leaf sundew chitinase (Drosera rotundifolia L.) in three E. coli expression strains Optimalizácia podmienok expresie droserovej chitinázy (Drosera rotundifolia L.) v troch expresných kmeňoch E. coli

Round-leaf sundew (Drosera rotundifolia L.), family Droseraceae, genus Drosera, is one of a few plant species with a strong antifungal potential. Chitinases of carnivorous plants play an important role in decomposition of chitin-containing cell structures of insect prey. The cell wall of many phytopathogenic fungi also contains chitin, which can be utilized by chitinases, thus round-leaf sundew...

An Improved 2-step Liquid Culture System for Efficient In Vitro Shoot Proliferation of Sundew (Drosera rotundifolia L.)

An efficient procedure for in vitro shoot production of the medicinal plant sundew (Drosera rotundifolia L.) was developed. Of three cytokinins tested, zeatin (ZEA) at a concentration of 2 μM resulted in the formation of large numbers of adventitious shoots on leaf explants. A larger size of the small shoots was achieved by combining a 2-weeks preculture with ZEA (step 1: shoot induction) with ...

Red trap colour of the carnivorous plant Drosera rotundifolia does not serve a prey attraction or camouflage function.

The traps of many carnivorous plants are red in colour. This has been widely hypothesized to serve a prey attraction function; colour has also been hypothesized to function as camouflage, preventing prey avoidance. We tested these two hypotheses in situ for the carnivorous plant Drosera rotundifolia. We conducted three separate studies: (i) prey attraction to artificial traps to isolate the inf...

Effect of Increased Atmospheric Nitrogen Deposition and Elevated CO2 on Traits Responsible for Carnivory in the Sundews Drosera rotundifolia and Drosera intermedia Senior Honors Thesis by Chloe White Program

Two experiments were conducted to study the effects of increased atmospheric nitrogen deposition and elevated CO2 on investment in carnivory by two sundew species, Drosera rotundifolia and D. intermedia. A field study was conducted with D. rotundifolia at Inverness Mud Lake Bog in Inverness Twp., MI where plants were exposed to simulated future increases in atmospheric nitrogen deposition predi...
