Chapter 13 Photo-stimulated effects on diatom motility

摘要: Abstract Like many unicellular algae, benthic diatoms have active motility to help regulate their access necessary resources such as light. However, diatom cells are constrained within a hardened silicate-based cell wall, which restricts movement characteristic gliding motion along the surface they attached. The restriction on results in motile system with severe spatial constraints changing direction and orientation. This chapter outlines historical work relating investigations generation regulation of movement, particular how this is affected by light (such photo-based response generating changes at light/dark boundaries). Additionally, article discusses recent comparative differences between adhesive abilities different species, other environmental influences affect them. crucial ecological success it both cells' well helps determine segregation species into microniches algal communities. Diatom affects accessibility nutrients exposure loss due predation or physical disturbance. Light-based responses thus likely be fundamental components strategies for long-term viability aquatic ecosystems.
