title: Postembryonic Hourglass Patterns Mark Ontogenetic Transitions in Plant Development
design: RNA extraction  RNA extraction was performed with the RNeasy Plant Mini Kit (QIAGEN) including the on- column DNase digestion step according to the manufacturer’s protocols. Integrity of the RNA was verified by agarose gel electrophoresis.  RNA-Seq Analysis  Library preparation and Illumina RNA-seq was performed by LGC Genomics.
