Abstract
In order to study the transcriptome of individual plant cells at specific points in time, we developed protocols for fixation, embedding, and sectioning of plant tissue followed by laser capture microdissection (LCM) and processing for RNA recovery. LCM allows the isolation of individual cell types from heterogeneous tissue sections and is particularly suited to plant processing because it does not require the breakdown of cell walls. This approach allows accurate separation of a small volume of cells that can be used to study gene expression profiles in different tissues or cell layers. The technique does not require separation of cells by enzymatic digestion of any kind, does not require cell-specific reporter genes, and allows storage of fixed and embedded tissue for months before capture. The methods for fixation, embedding, sectioning, and capture of plant cells that we describe yield high-quality RNA suitable for making libraries for RNASeq. © 2018 by John Wiley & Sons, Inc.
