Abstract
Our understanding of gene regulation is constantly evolving. It is now clear that
the majority of cellular transcripts are non-coding RNAs. The spectrum of non-coding
RNAs is diverse and includes short (<200 nt) and long non-coding RNAs (lncRNAs) (>200 nt).
LncRNAs regulate gene expression through diverse mechanisms. In this review, we describe
the emerging roles of lncRNA mediated plant gene regulation. We discuss the current
classification of lncRNAs and their role in genome organization and gene regulation.
We also highlight a subset of lncRNAs that are epigenetic regulators of plant gene
expression. Lastly, we provide an overview of emerging techniques and databases that
are employed for the identification and characterization of plant lncRNAs.
