Molecular Cross-Talk between Gravity- and Light-Sensing Mechanisms in .

is a photosynthetic flagellate. To acquire a suitable position in its surrounding aquatic environment, it exploits light and gravity primarily as environmental cues. Several physiological studies have indicated a fine-tuned relationship between gravity sensing (gravitaxis) and light sensing in .

-Mediated Nuclear Transformation of a Biotechnologically Important Microalga-.

() is an attractive organism due to its evolutionary history and substantial potential to produce biochemicals of commercial importance. This study describes the establishment of an optimized protocol for the genetic transformation of mediated by (). was found to be highly sensitive to hygromycin and zeocin, thus offering a set of resistance marker genes for the selection of transformants.

Changes of Gene Expression in Euglena gracilis Obtained During the 29 DLR Parabolic Flight Campaign.

Parabolic flight maneuvers of Novespace's Airbus A310 ZERO-G produce subsequent phases of hypergravity (about 20 s), microgravity (about 22 s) and another 20 s hypergravity on experiments located in the experiment area of the aircraft. The 29 DLR parabolic flight campaign consisted of four consecutive flight days with thirty-one parabolas each day. Euglena gracilis cells were fixed with TRIzol during different acceleration conditions at the first and the last parabola of each flight.

Transcriptome, proteome and draft genome of Euglena gracilis.

Background: Photosynthetic euglenids are major contributors to fresh water ecosystems. Euglena gracilis in particular has noted metabolic flexibility, reflected by an ability to thrive in a range of harsh environments. E.

Identification of a flagellar protein implicated in the gravitaxis in the flagellate Euglena gracilis.

Flagellated cells are of great evolutionary importance across animal and plant species. Unlike higher plants, flagellated cells are involved in reproduction of macro-algae as well as in early diverging land plants. Euglena gracilis is an emerging flagellated model organism.
