Abstract:
Plant small RNAs are ∼20 to 24 nucleotide noncoding RNAs that typically have repressive regulatory roles in gene expression, functioning at the transcriptional or post-transcriptional level. This influence on regulation of developmental and physiological processes has direct effects on phenotype. High-throughput sequencing technologies have enabled the sequencing of millions of small RNAs. Along with decreased sequencing costs, recent improvements in small RNA library construction have facilitated the ability to use minimal amounts of input RNA for analysis. This unit describes steps to isolate total RNA from limited amounts of plant tissue to construct small RNA libraries and perform small RNA data processing. © 2017 by John Wiley & Sons, Inc.

RNA Interference
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...
