Summary
Circular RNAs (circRNAs) are key non-coding RNAs in eukaryotes. This review details plant circRNA discovery, biogenesis, and roles in stress response, highlighting research gaps.
Area of Science:
- Molecular Biology
- Genomics
- Plant Science
Background:
- Circular RNAs (circRNAs) are a class of non-coding RNAs formed by backsplicing.
- Once dismissed as splicing errors, circRNAs are now recognized for their regulatory roles.
- Research on plant circRNAs lags behind that in animals, representing an emerging field.
Purpose of the Study:
- To review the current state of plant circular RNA research.
- To cover circRNA discovery, biogenesis, characteristics, and functions in plants.
- To identify challenges and future research directions in plant circRNA studies.
Main Methods:
- Literature review and synthesis of existing research on plant circRNAs.
- Discussion of identification tools and biogenesis mechanisms.
- Summary of functional roles and regulatory potential.
Main Results:
- Plant circRNAs exhibit unique circularization features, expression specificity, conservation, and stability.
- Key identification tools, types, and biogenesis pathways are described.
- Potential roles as miRNA sponges, translation templates, and in stress response are highlighted.
Conclusions:
- Plant circRNAs have diverse functions and regulatory potential, particularly in stress responses.
- Further research is needed to fully elucidate their roles and mechanisms.
- The field of plant circRNA research is poised for significant growth and discovery.

01:25Cell Signaling in Plants
5.8K
Plant cells communicate to coordinate their cycle of growth, flowering and fruiting, and activities in roots, shoots, and leaves in response to the changing environmental conditions. Plant signaling is distinct from animal signaling. Plants primarily utilize enzyme-linked receptors, whereas the largest class of cell-surface receptors in animals are G-protein coupled receptors (GPCRs). Unlike animals, receptor tyrosine kinases are rare in plants. Instead, plants have a diverse class of...

01:56Riboswitches
8.7K
Riboswitches are non-coding mRNA domains that regulate the transcription and translation of downstream genes without the help of proteins. Riboswitches bind directly to a metabolite and can form unique stem-loop or hairpin structures in response to the amount of the metabolite present. They have two distinct regions – a metabolite-binding aptamer and an expression platform.
The aptamer has high specificity for a particular metabolite which allows riboswitches to specifically regulate...

02:53Ribosomal RNA Synthesis
13.5K
Ribosome synthesis is a highly complex and coordinated process involving more than 200 assembly factors. The synthesis and processing of ribosomal components occurs not only in the nucleolus but also in the nucleoplasm and the cytoplasm of eukaryotic cells.
Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...

02:12Short-distance Transport of Resources
16.5K
Short-distance transport refers to transport that occurs over a distance of just 2-3 cells, crossing the plasma membrane in the process. Small uncharged molecules, such as oxygen, carbon dioxide, and water, can diffuse across the plasma membrane on their own. In contrast, ions and larger molecules require the assistance of transport proteins due to their charge or size. Transport across membranes also occurs within individual cells, playing a variety of essential roles for the plant as a whole.

01:53Bacterial Transcription
29.9K
RNA polymerase (RNAP) carries out DNA-dependent RNA synthesis in both bacteria and eukaryotes. Bacteria do not have a membrane-bound nucleus. So, transcription and translation occur simultaneously, on the same DNA template.
Transcription can be divided into three main stages, each involving distinct DNA sequences to guide the polymerase. These are:

02:39lncRNA - Long Non-coding RNAs
9.0K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...
