Hypothesis
Does the obligate pathogen Blumeria graminis possess all amino acid biosynthetic pathways found in free-living fungi?
Conclusion
Blumeria graminis possesses all amino acid biosynthetic pathways found in free-living fungi.
Supporting Evidence
- Blumeria graminis is an obligate pathogen that cannot grow on defined media.
- The database allows for comparative analysis of genes encoding amino acid biosynthetic enzymes.
- Probability values indicate the presence or absence of amino acid pathways in various fungal species.
Takeaway
Scientists created a database to help find genes in fungi that make amino acids, showing that some fungi can make all the amino acids they need.
Methodology
The study used a relational database to analyze gene sequences from various fungal species and performed Bayesian probability analysis.
Potential Biases
The assumption that EST data represents a random sample of genes in a genome is likely violated due to expression patterns.
Limitations
The analysis relies on partial EST datasets, which may not represent a random sample of the genome.
