RNA-seq of major tissues and xylem cell types of Populus trichocarpa

We used the stem cross-sections of P. trichocarpa and our recently developed laser capture microdissection (LCM) to collect fibers, vessels, and a combination of 3 cell types (fibers + vessels + rays). Total RNA from the three samples was isolated, amplified, and analyzed by full-transcriptome RNA-sequencing. The sequencing reads were mapped to the P. trichocarpa genome. Overall design: Different major tissues (shoot tip, leaf, phloem, primary root, stem differentiating xylem) and xylem tissue cell types (fiber, vessel, ray cells) were analyzed by RNA-seq.
