Gravity-directed calcium current in germinating spores of Ceratopteris richardii

  title={Gravity-directed calcium current in germinating spores of Ceratopteris richardii},
  author={Ani Chatterjee and David Marshall Porterfield and Peter J. S. Smith and Stanley J. Roux},
 Gravity directs the early polar development in single cells of Ceratopteris richardii Brogn. It acts over a limited period of time during which it irreversibly determines the axis of the spore cell's development. A self-referencing calcium selective electrode was utilized to record the net movement of calcium across the cell membrane at different positions around the periphery of the spore during the period in which gravity orients the polarity of the spore. A movement of calcium into the cell… CONTINUE READING
