Summary
Long non-coding RNAs (lncRNAs) are abundant in plants and regulate key processes. This review covers plant lncRNAs, including viroids and endogenous lncRNAs, and their functions.
Area of Science:
- Plant molecular biology
- RNA biology
- Genomics
Background:
- Deep sequencing reveals most plant RNAs are non-coding, including long non-coding RNAs (lncRNAs).
- lncRNAs are emerging as crucial regulators in plant development and stress responses.
- Viroids, infectious subviral pathogens, are also a type of plant lncRNA.
Purpose of the Study:
- To review the current understanding of plant long non-coding RNAs (lncRNAs).
- To discuss the roles of endogenous lncRNAs in plant regulatory processes.
- To explore viroid biology and their interactions with host plants.
Main Methods:
- Analysis of transcriptome deep-sequencing data.
- Review of existing literature on plant lncRNAs and viroids.
- Elucidation of viroid-host interactions through experimental data.
Main Results:
- lncRNAs play significant roles in flowering, abiotic stress response, and hormone signaling in plants.
- Viroids are circular RNA pathogens that hijack host machinery for replication.
- Emerging research highlights the diverse functions of endogenous lncRNAs in plants.
Conclusions:
- Plant lncRNAs, both endogenous and exogenous (viroids), are critical for plant biology.
- Further research into lncRNA functions will advance our understanding of plant regulation and disease.
- This review synthesizes current knowledge on plant lncRNAs and viroid-host interactions.

Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...

RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

01:10Retrovirus Life Cycles
50.6K
Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...

Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...

1.1K
Viral genomes exhibit remarkable diversity in size, structure, and composition, influencing their replication strategies and interactions with host cells. These genomes consist of either DNA or RNA and may be linear or circular. Additionally, they can be single-stranded or double-stranded, with each configuration affecting how the virus propagates within a host. RNA viruses, for instance, generally have smaller genomes than DNA viruses, a factor that contributes to their high mutation rates and...
