Through the analysis of molecular biology, the relations between organisms and the evolutionary order of the species were inferred, not only through visual characteristics but also through genomic characteristics. Vitamin B1 (Thiamine) is a vital micronutrient required by all organisms. In view of the importance of this coenzyme, this work analyzed the TPK gene of the thiamine biosynthesis pathway in the evolution of terrestrial plants, using phylogenetic analysis tools. Thus, by evaluating the variations in protein level of the TPK gene, it was possible to reflect the evolution of the large groups of plants, and even the proximity between species, families and orders.
