Amaranth Genomic Resource Database: an integrated database resource of Amaranth genes and genomics

Area of Science:

• Plant genomics
• Bioinformatics
• Crop science

Background:

• Amaranth (Amaranthus L.) is a globally cultivated crop with high nutritional value, native to Mexico and North America.
• High-quality genome assemblies for several cultivated and wild amaranth species are available.
• Existing genomic data is fragmented, hindering comprehensive analysis and utilization.

Purpose of the Study:

• To develop a centralized, integrated genomic resource database for amaranth species.
• To provide easy access to diverse genomic information, including genes, SSRs, SNPs, TFs, miRNAs, and transporters.
• To facilitate genetic improvement and characterization of amaranth as a future crop.

Main Methods:

• Development of the Amaranth Genomic Resource Database (AGRDB).
• Integration of functionally annotated gene data, SSRs, SNPs, transcription factors (TFs), miRNAs, and transporters for five amaranth species.
• Implementation of search functionalities (gene ID, sequence, keywords, etc.) and visualization tools (JBrowse, BLAST).

Main Results:

• The AGRDB provides access to annotated genes, genic/genomic SSRs with primers, TF families, putative miRNAs, transporter genes, and genic/nongenic SNPs.
• The database includes sequence details, annotation information, and flanking sequences for SNPs.
• Integrated tools like JBrowse and BLAST enable genome visualization and sequence similarity searches.

Conclusions:

• The AGRDB serves as a valuable, unified platform for amaranth genomic research.
• This resource is expected to accelerate the genetic improvement and detailed characterization of amaranth.
• The database is accessible online for researchers worldwide.
