Main conclusion: Present review addresses the advances made in the understanding of biogenesis of plant small RNAs
and their role in plant development. We discuss the elaborate role of microRNAs (miRNAs) and trans-acting small
interfering RNAs (ta-siRNAs) in various aspects of plant growth and development and highlight relevance of small
RNA mobility.
Small non-coding RNAs regulate various aspects of plant development. Small RNAs (sRNAs) of 21–24 nucleotide length are
derived from double-stranded RNAs through the combined activity of several biogenesis and processing components. These
sRNAs function by negatively regulating the expression of target genes. miRNAs and ta-siRNAs constitute two important
classes of endogenous small RNAs in plants, which play important roles in plant growth and developmental processes like
embryogenesis, organ formation and patterning, shoot and root growth, and reproductive development. Biogenesis of miRNAs
is a multistep process which includes transcription, processing and modifcation, and their loading onto RNA-induced
silencing complex (RISC). RISC-loaded miRNAs carry out post-transcriptional silencing of their target(s). Recent studies
identifed orthologues of diferent biogenesis components of novel and conserved small RNAs from diferent model plants.
Although many small RNAs have been identifed from diverse plant species, only a handful of them have been functionally
characterized. In this review, we discuss the advances made in understanding the biogenesis, functional conservation/divergence
in miRNA-mediated gene regulation, and the developmental role of small RNAs in diferent plant species.
