RNA-Seq analysis identifies potential modulators of gravity response in Ceratopteris spores: Evidence for modulation by calcium pumps and apyrase activity

Gravity regulates the magnitude and direction of a trans-cell calcium current in germinating spores of Ceratopteris richardii. Blocking this current with nifedipine blocks the spore s downward polarity alignment a polarization that is fixed by gravity 10 h after light induces the spores to germinate. RNA-seq analysis at 10 h was used to identify genes potentially important for the gravity response. The data set will be valuable for other developmental and phylogenetic studies.
