GURFAP: A Platform for Gene Function Analysis in Glycyrrhiza Uralensis

Area of Science:

• Plant genomics and bioinformatics
• Molecular biology
• Natural product biosynthesis

Background:

• Glycyrrhiza uralensis (Licorice) is valued for its pharmacological properties and as a natural sweetener.
• The recent completion of the G. uralensis genome provides a foundation for gene function studies.
• Understanding gene function is crucial for optimizing the production of active compounds.

Purpose of the Study:

• To integrate genomic and transcriptomic data for G. uralensis.
• To construct a gene co-expression network and annotate gene functions.
• To develop a user-friendly platform (GURFAP) for gene function analysis in G. uralensis.

Main Methods:

• Genome and transcriptome data integration.
• Gene co-expression network construction.
• Gene family prediction using iTAK, HMMER, InParanoid, and PfamScan.
• Functional annotation via BLAST, GSEA, Motif, Heatmap, and JBrowse.
• Development of the GURFAP platform (www.gzybioinfoormatics.cn/GURFAP).

Main Results:

• A comprehensive G. uralensis gene co-expression network was established.
• Gene functions were annotated, and gene families were predicted.
• The GURFAP platform was successfully developed and validated.
• Analysis suggested MYB and bHLH transcription factors regulate glycyrrhizin biosynthesis.
• Specific genes (CYP88D6, CYP72A154, bAS) in glycyrrhizin synthesis were highlighted.

Conclusions:

• The GURFAP platform offers a valuable resource for G. uralensis gene function research.
• The platform facilitates the discovery of key genes in active ingredient biosynthesis.
• This work advances the understanding of glycyrrhizin biosynthesis pathways.
