Establishing a comprehensive web-based analysis platform for Nicotiana benthamiana genome and transcriptome

Area of Science:

• Plant molecular biology
• Bioinformatics
• Plant pathology

Background:

• Nicotiana benthamiana is a vital model organism in plant physiology and pathology due to its susceptibility to viruses.
• Its genome is large, with over 57,000 annotated genes, necessitating advanced analytical tools.
• It serves as a platform for testing vaccines and other valuable substances.

Purpose of the Study:

• To create a comprehensive and user-friendly platform for transcriptome analysis in Nicotiana benthamiana.
• To enable visualization of gene expression profiles, phylogenetic analysis, and functional enrichment.
• To demonstrate the platform's utility by analyzing the nicotine biosynthesis pathway.

Main Methods:

• Development of a bioinformatics platform for transcriptome data analysis.
• Visualization of gene expression profiles for specific pathways.
• Comparative analysis of gene expression patterns with existing data.

Main Results:

• The developed platform successfully generated gene expression profiles for the nicotine biosynthesis pathway.
• Expression patterns revealed strong expression in roots and weak expression in leaves and flowers for eight gene groups.
• Results align with known expression profiles in Nicotiana tabacum, validating the tool's accuracy.

Conclusions:

• The new transcriptome analysis platform facilitates modern annotation and genetic analysis of Nicotiana benthamiana.
• The study provides insights into gene family composition and expression trends within the nicotine biosynthesis pathway.
• This resource will aid future research in plant genetics and secondary metabolism.
