Structures and Functions of Retinal Proteins
Mutants which lack all retinal proteins in halobacteria are phototactically but not
chemotactically deficient (Sundberg et al.,1990) . There are two other retinal
proteins in halobacteria, namely bacteriorhodopsin (BR) and halorhodopsin (HR)
...
Approximately 200 randomly picked isolates were tested phototactically, of these
one had a lengthened clock period, two had shortened periods and one had an
atypical phase. Strains were maintained by monthly transfer on 0.3 HSM agar ...

What Good Are Bugs? Insects in the Web of Life
He hypothesized that they responded to the light from the burrow's entrance.
Such responses are often phototactic, instinctive orientations to light. In
laboratory experiments, he found that sand martin fleas do indeed respond
phototactically.

Avian Migration: With 32 Tables
2001), we showed that in the apparent scatter of the distributions, in fact the
single individuals were orienting quite precisely, some being correctly oriented,
some phototactically. Bimodal individuals are relatively rare. We proposed the ...

Dictyostelium Discoideum Protocols
Slugs were formed from amoebae of strain X22 or HU410 and allowed to migrate
phototactically, transferred to polyvinylchloride discs, stained, and analyzed
using the unidirectional and bidirectional von Mises models as described under ...

... modification of the suspension assay, freely motile cells are pre-oriented by
weak phototactically-active light (Figure 2.2D) or gravitaxis. In early work, two
major components of the photoelectric cascade in green f lagellate algae ...

These cells lack eyespots during logarithmic growth but form them as they reach
stationary phase (Figure 2.22; Table 2.7). The eye1 mutants retain the ability to
respond phototactically, but their orientation is less precise than that of wild-type
...

Photomorphogenesis in Plants
In light, slugs orientate exclusively positively phototactically with an action
spectrum which differs significantly from that of the amoebae; it has two peaks at
420 and 440 nm and smaller additional maxima up to 610 nm. The difference
between ...
Richard E. Kendrick, G. H. M. Kronenberg, 1994
Found that more larvae settled in grooved microrefuges, and in particular in their
shaded portions, suggesting they are detected phototactically. In the laboratory,
survival of sponge larvae in grooves was enhanced after exposure to bulldozing

The Development Of Dictyostelium Discoideum
quence of aggregation is the formation of the pseudoplasmodium, or slug, which
migrates phototactically and thermotactically to the upper layer of the soil. At this
point, the slug “culminates” to form a fruiting body consisting of a ball of spores ...
