Journal ArticleDOI
Phototaxis in a wild isolate of the cyanobacterium Synechococcus elongatus.
Yiling Yang,Vinson Lam,Marie Adomako,Ryan Simkovsky,Annik Jakob,Nathan C. Rockwell,Susan E. Cohen,Susan E. Cohen,Arnaud Taton,Jingtong Wang,J. Clark Lagarias,Annegret Wilde,David R. Nobles,Jerry J. Brand,Susan S. Golden +14 more
TL;DR: A wild isolate of S. elongatus, UTEX 3055, is characterized and a six-gene operon encoding chemotaxis-like proteins was confirmed to be involved in phototaxis, establishing a phototactic model organism for cyanobacteria.
Journal ArticleDOI
The (PATAN)-CheY-Like Response Regulator PixE Interacts with the Motor ATPase PilB1 to Control Negative Phototaxis in the Cyanobacterium Synechocystis sp. PCC 6803
TL;DR: Study of the phototactic behavior of pixE deletion and overexpression mutants in response to unidirectional red light with or without additional blue-light irradiation suggests that multiple environmental signals can be integrated via these regulators to control pilus function.
Journal ArticleDOI
Ethylene production in Synechocystis sp. PCC 6803 promotes phototactic movement.
Ekaterina Kuchmina,Stephan Klähn,Annik Jakob,Werner Bigott,Heike Enke,Ulf Dühring,Annegret Wilde +6 more
TL;DR: Surprisingly, ethylene production triggers a very specific transcriptional response and only a few other smaller transcriptional changes are detected in the microarray analysis.
Journal ArticleDOI
Phototaxis Assays of Synechocystis sp. PCC 6803 at Macroscopic and Microscopic Scales
TL;DR: A detailed procedure for phototaxis assays on both scales using the unicellular cyanobacterium Synechocystis sp.
Proceedings ArticleDOI
Influence of surface roughness on the optical mode profile in GaN-based violet ridge waveguide laser diodes
TL;DR: In this paper, the influence of the epitaxial layer roughness on the far-field profile of the optical mode in gallium nitride-based, c-plane ridge waveguide laser diodes was investigated.
