Plant long noncoding RNAs: why do we not know more?

Area of Science:

• Genomics
• Molecular Biology
• Bioinformatics

Background:

• Human and animal genomic databases are well-developed, aiding disease research and personalized medicine.
• Plant genomic databases are rapidly advancing but less comprehensive due to genome complexity and lower funding.
• Long non-coding RNAs (lncRNAs) are vital for organism development, but their study in plants faces significant challenges.

Purpose of the Study:

• To review the current state of knowledge on plant lncRNAs.
• To highlight obstacles in plant lncRNA research, particularly in forest trees.
• To explore the potential of lncRNA research in revolutionizing agriculture and forestry.

Main Methods:

• Comparative analysis of genomic database development across species.
• Review of challenges in plant genome and lncRNA research (complexity, polyploidy, epigenetics).
• Exploration of computational approaches for advancing lncRNA studies.

Main Results:

• Significant disparities exist in genomic database comprehensiveness between plants and other kingdoms.
• Plant genome complexity, including polyploidy and epigenetic modifications, complicates lncRNA research.
• lncRNAs in plants, especially forest trees, offer potential for climate change adaptation in agriculture and forestry.

Conclusions:

• Robust and complete plant lncRNA databases are urgently needed.
• Computational analyses are key to overcoming research challenges.
• lncRNA research in forest trees is critical for addressing global environmental challenges and enhancing agricultural resilience.
