JustRNA: a database of plant long noncoding RNA expression profiles and functional network

Area of Science:

• Plant molecular biology
• Genomics
• Bioinformatics

Background:

• Long noncoding RNAs (lncRNAs) are crucial regulatory molecules in biological processes, yet their specific functions in plants are not fully understood.
• Investigating lncRNA activity and co-expression with protein-coding genes is essential for deciphering their regulatory roles.
• A comprehensive resource is needed to facilitate the study of plant lncRNA expression profiles and interactions.

Purpose of the Study:

• To develop JustRNA, a comprehensive expression profiling resource for plant long noncoding RNAs (lncRNAs).
• To provide tools for investigating lncRNA regulatory mechanisms, including functional networks, genomic associations, and microRNA interactions.
• To integrate diverse datasets, such as RNA-seq, ChIP-seq, and epigenetic modifications, for a holistic view of lncRNA regulation.

Main Methods:

• Development of the JustRNA platform, incorporating 1,088,565 lncRNA annotations across 80 plant species.
• Inclusion of 3,692 RNA-seq samples from 825 conditions in six model plants.
• Integration of functional network reconstruction, genomic association analysis, microRNA target prediction, and ChIP-seq data for transcription factors and histone modifications.

Main Results:

• The JustRNA platform offers extensive lncRNA annotations and expression data for a wide range of plant species.
• Functional network analysis, genomic association, and miRNA target prediction tools are available to explore lncRNA interactions.
• Integration of epigenetic data provides insights into the transcriptional regulation of plant lncRNAs.

Conclusions:

• JustRNA serves as a valuable, free resource for researchers studying plant lncRNA regulatory mechanisms.
• The platform facilitates a deeper understanding of lncRNA functions and their interactions with genes and miRNAs in plants.
• JustRNA empowers the plant science community with comprehensive data and analytical tools for lncRNA research.
