Abstract:
In animals and plants, small RNAs have been identified as important regulatory factors controlling cell fate. A bidirectional cell-to-cell communication involving the mobile transcription factor SHR and microRNA165/166 species specifies the radial position of two types of xylem vessels in Arabidopsis roots. The microRNAs provide short-range non-cell-autonomous developmental signals that are transported through the plasmodesmata (PD) via the symplastic pathway. 21-24 nucleotide-long small RNA species have been shown to move from the shoot to the root. In this review, we highlight the presence of small RNA species as an emerging class of important mobile signals associated with the growth and development of the root.

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...

siRNA - Small Interfering RNAs
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the ATP-dependent...
Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.
