Gravitaxis in Chlamydomonas reinhardtii studied with novel mutants.

Plant & cell physiology - 1 Oct 2003

Yoshimura Kenjiro, Matsuo Yudo, Kamiya Ritsu

Abstract excerpt

Many free-swimming unicellular organisms show negative gravitaxis, i.e. tend to swim upward, although their specific densities are higher than the medium density. To obtain clues to the mechanism of this behavior, we examined how a mutation in motility or behavior affects the gravitaxis in Chlamydomonas. A phototaxis mutant, ptx3, deficient in membrane excitability showed weakened gravitaxis, whereas another...
