  1. + = Positive PCR product present in repeat experiments.
  2. - = No product detected in repeat PCR amplifications.
  3. +P refers to the presence of tlp7 as two separately co-expressed genes.
  4. +W refers to a whole gene able to be translated into a complete protein product. Sequencing was performed in triplicate to ensure accuracy of the results.
