Hypothesis

Can a medium-throughput screening strategy effectively identify full-length coding sequences from incomplete cDNA tags?

Conclusion

The developed strategy efficiently converts incomplete expressed sequence tags to full-length coding sequences.

Supporting Evidence

  • The method identified 109 full-length clones from 163 cDNA-AFLP tags, achieving a success rate of 67%.
  • Multiple probes can be used in a single hybridization event, increasing throughput.
  • The strategy allows for the screening of approximately 100,000 cDNA clones in a rapid manner.

Takeaway

The researchers found a way to quickly identify complete gene sequences from partial ones, which helps in studying plant genes better.

Methodology

A medium-throughput screening strategy combining PCR and colony hybridization was used to identify full-length clones from cDNA libraries.

Limitations

The method may not be specific for full-length clones and relies on the quality of the cDNA library.
