High-resolution profiling of small RNAs in the Arabidopsis thaliana root

Small noncoding RNAs (ncRNAs) are key regulators of plant development through modulation of the processing, stability and translation of larger RNAs. In this project we present small RNA datasets produced from over 200 million Illumina sequencing reads covering all major cell types of the root (epidermis, cortex, endodermis, vascular tissue or stele, and columella) as well as four distinct developmental zones (early meristematic, late meristematic, elongation, early differentiation).
