Germplasm Phenotype:

• AtTPK1-KO  — The AtTPK1-KO single mutant does not have any obvious aberrant phenotypes, but, the AtTPK1-KO /AtTPK2-KO double mutant demonstrates that these enzymes are required to produce thiamine pyrophosphate from thiamine.
• AtTPK1/2-KO  — These double knock-out mutants are thiamine auxotrophs that have a seedling lethal phenotype unless they are supplied with exogenous thiamine pyrophosphate (TPP) through a spray-based application. In addition, these mutants have 2-fold higher levels of thiamine and 32-fold lower levels of TPP than wild type plants.
