Cladogram representation of the findings regarding the annotation of GULO in 16 Acari species. The species in which GULO is likely present are highlighted in green, the species where the presence or absence of GULO cannot be inferred are highlighted in blue, the species in which the annotations may be the result of genome contamination are highlighted in orange and the species where GULO is probably absent are highlighted in red. The pink and light blue regions differentiate the Acari species analyzed into two superorders, respectively Parasitiformes and Acariformes. The Parasitiformes group can be seen divided in two distinct orders, Ixodida and Mesostigmata. The cladogram branches represent the taxonomic relationship between the species analyzed, depicted as in [30,31,32,33,34]
