Phylogenetic tree of Phoenicimicrobiia putative FaeA. Reference sequences of AssA, BssA, HbsA, and HmsA were obtained from previous studies [1]. The genes were aligned using MUSCLE [39] with 100 iterations, and divergent regions were eliminated using TrimAL [40]. The IQ-Tree was used for phylogenetic inference [41], and the best model LG+F+I+G4 was well supported by Bayesian Information Criterion (BIC). Bootstrap values >Â 80 were shown in black dots
