Photopolarization of Fucus zygotes is determined by time sensitive vectorial addition of environmental cues during axis amplification [PDF]
, 2015 Fucoid zygotes have been extensively used to study cell polarization and asymmetrical cell division. Fertilized eggs are responsive to different environmental cues (e.g., light, gravity) for a long period before the polarity is fixed and the cells ...
