Abstract

Diatoms are species-rich microalgae that often have a unique life cycle with vegetative cell size reduction followed by size restoration through sexual reproduction of two mating types (MT+ and MT). In the marine benthic diatom Seminavis robusta, mate-finding is mediated by an l-proline-derived diketopiperazine, a pheromone produced by the attracting mating type (MT). Here, we investigate the movement patterns of cells of the opposite mating type (MT+) exposed to a pheromone gradient, using video monitoring and statistical modeling. We report that cells of the migrating mating type (MT+) respond to pheromone gradients by simultaneous chemotaxis and chemokinesis. Changes in movement behavior enable MT+ cells to locate the direction of the pheromone source and to maximize their encounter rate towards it.

Movie S1

The movie shows the attraction and accumulation of Seminavis robusta MT+ cells towards the diproline-loaded bead. Cells repeatedly touch the bead as an attempt to pair. The movie was accelerated 50 times and the scale bar indicates 50 μm. (AVI 27603 kb)

Movie S2

The movie shows that a control bead did not induce any reaction from S. robusta MT+ cells. The movie was accelerated 50 times and the scale bar indicates 50 μm. (AVI 27112 kb)
