CANTATAdb 3.0: An Updated Repository of Plant Long Non-Coding RNAs

Area of Science:

• Plant biology
• Genomics
• Bioinformatics

Background:

• Long non-coding RNAs (lncRNAs) play crucial roles in gene regulation and development.
• Previous versions of CANTATAdb have provided valuable resources for plant lncRNA research.
• Expanding the catalog of plant lncRNAs and their characteristics is essential for understanding plant biology.

Purpose of the Study:

• To update and expand CANTATAdb with a comprehensive collection of plant long non-coding RNAs.
• To identify and characterize tissue-specific and evolutionarily conserved lncRNAs across a wide range of plant species.
• To facilitate functional studies and comparative genomics of plant lncRNAs.

Main Methods:

• Identification of lncRNAs across 108 plant species, including 100 Magnoliopsida.
• Analysis of lncRNA expression patterns, focusing on organ-specific and embryonic expression.
• Detection of evolutionarily conserved lncRNAs using genome-genome alignments and similarity searches.
• Data curation and integration into the CANTATAdb 3.0 resource.

Main Results:

• CANTATAdb 3.0 contains 571,688 lncRNAs from 108 species.
• 112,980 lncRNAs exhibit tissue-specific expression, suggesting developmental roles.
• 74,886 pairs of conserved lncRNAs were identified, with conserved lncRNAs showing conserved organ occupancy across species.
• The database offers enhanced search functionalities and data download options.

Conclusions:

• CANTATAdb 3.0 represents a significant expansion in plant lncRNA resources.
• The identified tissue-specific and conserved lncRNAs provide valuable candidates for functional investigation.
• Conserved lncRNA expression patterns across species suggest conserved biological functions in plant development and organogenesis.
