RNA-seq of enriched barley stomatal complexes versus total leaves

We intend to identify transporters and their regulators involved in barley stomatal movement as well as components of the ABA signaling pathway. We isolated epidermal peels where only stomatal guard cells and their subsidiary cells survived, while other epidermal cell were mechanically disrupted and sequenced the resulting RNAs. Thus we analyzed transcripts differentially expressed between the barley stomatal complex and total leaves. These data served as the first overview of genes expressed in the stomatal complex and for cloning of relevant transporters.
