Small RNA-Sequencing Library Preparation for the Halophilic Archaeon Haloferax volcanii.

Posttranscriptional regulation actuated by small RNAs (sRNAs) plays essential roles in a wide variety of cellular processes, especially in stress responses and environmental signaling. Hundreds of sRNAs have recently been discovered in archaea using genome-wide approaches but the molecular mechanisms of only a few have been characterized experimentally. Here, we describe how to build sRNA sequencing libraries using size-selected total RNA in the model archaeon, Haloferax volcanii , to provide a tool to further characterize sRNAs in archaea.
