Genome Update. Let the consumer beware: Streptomyces genome sequence quality

Area of Science:

• Genomics
• Bioinformatics

Background:

• A genome sequence assembly serves as a fundamental model of an organism's genome.
• Evaluating the quality of these assemblies is essential for downstream biological interpretation and research.

Purpose of the Study:

• To explore tools and methods for assessing genome assembly quality.
• To use publicly available Streptomyces species genome data as a case study.

Main Methods:

• Utilized publicly available genome sequence assembly data.
• Examined assemblies deposited in GenBank, focusing on Streptomyces species.
• Assessed the availability of raw sequencing data for quality appraisal.

Main Results:

• Observed significant variability in the quality of genome assemblies.
• Found that only a small fraction of deposited assemblies have readily available raw data.
• Limited raw data availability restricts comprehensive quality assessment.

Conclusions:

• The quality of genome assemblies in public databases is highly variable.
• The lack of accessible raw data impedes thorough quality control of genome assemblies.
• Standardized methods and data availability are needed for reliable genome assembly evaluation.
