Plant Noncoding RNAs: Hidden Players in Development and Stress Responses

Area of Science:

• Plant Molecular Biology
• Genetics
• Biochemistry

Background:

• Eukaryotic transcriptomes contain a substantial proportion of functional noncoding RNAs (ncRNAs).
• ncRNAs, encompassing small RNAs and long ncRNAs (lncRNAs), are crucial regulators of gene expression at transcriptional and posttranscriptional levels.
• These molecules are involved in nearly all biological processes.

Purpose of the Study:

• To review current knowledge on plant small RNAs and lncRNAs.
• To focus on their biogenesis, mechanisms of action, movement, and functions in plant development and environmental responses.
• To discuss interconnections between ncRNAs and small peptides, and challenges in ncRNA research.

Main Methods:

• Literature review and synthesis of existing research on plant ncRNAs.
• Analysis of data concerning small RNA and lncRNA biogenesis and function.
• Discussion of experimental and bioinformatic approaches for ncRNA identification.

Main Results:

• Plant ncRNAs, including small RNAs and lncRNAs, exhibit diverse regulatory roles in gene expression.
• These ncRNAs are involved in critical plant processes such as development and adaptation to environmental stimuli.
• Complex regulatory networks exist involving small RNAs, lncRNAs, and small peptides in plants.

Conclusions:

• Plant ncRNAs are essential for regulating gene expression, development, and environmental responses.
• Understanding the intricate interactions among different ncRNA types and peptides is crucial.
• Further research is needed to identify novel ncRNA classes and elucidate their functions.
