TriticeaeSSRdb: a comprehensive database of simple sequence repeats in Triticeae

Area of Science:

• Genomics
• Bioinformatics
• Plant Science

Background:

• Microsatellites, or simple sequence repeats (SSRs), are vital co-dominant markers in genetic analyses and molecular breeding.
• The Triticeae tribe, encompassing crucial cereal crops like wheat and barley, requires enhanced genetic resources for improvement.

Purpose of the Study:

• To develop an integrated and user-friendly database, TriticeaeSSRdb, for microsatellites within the Triticeae tribe.
• To facilitate genetic studies and accelerate molecular breeding strategies for important grass species.

Main Methods:

• Collected and curated 3,891,705 SSRs from 21 Triticeae species.
• Developed browsing and advanced search functionalities based on genomic location, motif type, and SSR length.
• Integrated tools for gene association, primer design, sequence alignment, and in silico SSR prediction.

Main Results:

• TriticeaeSSRdb provides comprehensive SSR data for 21 Triticeae species.
• The database offers advanced search, browsing, and practical bioinformatics tools.
• Includes functionalities for primer design and in silico SSR analysis.

Conclusions:

• TriticeaeSSRdb is a valuable resource for researchers in Triticeae genetics and breeding.
• The database is expected to significantly advance trait genetic analysis and molecular breeding in Triticeae crops.
• The resource is freely accessible online for the scientific community.
