Vectors

 

 

On this page you can find information on some of the different Fusarium graminearum mutants I have made. The information includes pictures, predicted function, reference to publication and the sequences of the Agrobacterium tumefaciens vectors used to generate the mutants. All deletion mutants  are true deletion / replacement mutants, meaning that part of or the whole coding sequence of the targeted gene has been replaced by the positive selection marker hygromycin phosphotransferase (hph).

We have chosen to use the abbreviation "aur" to describe the genes in the aurofusarin gene cluster. Information on mutants that have not been published is not shown and is marked with "na".

The pictures of the cultures is taken from the bottom of the dishes, and are captured after 7 days if not specified otherwise. All cultures  have been incubated at 25 °C in darkness, with the agar plates upside down.

If you are interested in one or two of the mutants - please contact  raf(at)bio.dtu.dk

Name: PKS12/aurC

THIS IS NOT A DESIGNED DOUBLE REPLACEMENT MUTANAT - IT JUST HAPPENED: The PKS12 genes is rendered non-functional due to a mutation in its coding sequence, which occured during integration of the aurC replacement vector.

At higher concentrations (the ability to complete aurofusarin biosynthesis is restored.
