siRNA - Small Interfering RNAs

siRNA - Small Interfering RNAs

Small interfering RNAs, or siRNAs, are short regulatory RNA molecules that can silence genes post-transcriptionally, as well as the transcriptional level in some cases. siRNAs are important for protecting cells against viral infections and silencing transposable genetic elements.
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...

RNA Interference

RNA Interference

RNA interference (RNAi) is a process in which a small non-coding RNA molecule blocks the post-transcriptional expression of a gene by binding to its messenger RNA (mRNA) and preventing the protein from being translated.
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...

Experimental RNAi

Experimental RNAi

RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...

piRNA - Piwi-interacting RNAs

piRNA - Piwi-interacting RNAs

PIWI-interacting RNAs, or piRNAs, are the most abundant short non-coding RNAs. More than 20,000 genes have been found in humans that code for piRNAs while only 2000 genes have been found for miRNAs. piRNAs can act at the transcriptional and post-transcriptional levels and have a vital role in silencing transposable elements present in germ cells. They are also involved in epigenetic silencing and activation. Previously, they were thought to function only in germ cells but new evidence suggests...

Nucleic Acids

Nucleic Acids

Nucleic acids are the most important macromolecules for the continuity of life. They carry the cell's genetic blueprint and carry instructions for its functioning.
DNA and RNA
The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material in all living organisms, ranging from single-celled bacteria to multicellular mammals. It is in the nucleus of eukaryotes and in the organelles, chloroplasts, and mitochondria. In prokaryotes, the...

Area of Science:

Plant molecular biology
Epigenetics
Developmental biology

Background:

Small non-coding RNAs (ncRNAs) are vital regulators of gene expression in plants.
While sporophytic ncRNAs are well-studied, gametophytic ncRNAs, particularly in angiosperms, are gaining attention.
Research in Arabidopsis male gametophytes reveals unique ncRNA features and functions.

Purpose of the Study:

To investigate the roles and characteristics of small RNAs in angiosperm gametophyte development.
To identify specific small RNA pathways and their functions in male gametophytes.
To explore the involvement of small RNAs in germline development and genome maintenance.

Main Methods:

Transcriptomic analysis
Deep-sequencing studies
Identification and characterization of small RNA pathways (e.g., miRNA, siRNA, nat-siRNA)

Main Results:

Over 100 microRNAs (miRNAs) are detected in male gametophytes during development.
Trans-acting small interfering RNA (siRNA) pathways and nat-siRNA pathways are crucial for pollen maturation and function.
siRNA-mediated silencing of transposable elements occurs in both male and female germ cells, analogous to piRNAs in animals.

Conclusions:

Small RNAs play an integral role in angiosperm gametophyte development.
Specific siRNA pathways are essential for male gamete function and maturation.
Further discovery of novel small RNAs involved in germline development and genome integrity is anticipated.
