“…Their genetic structure was reconstructed and, overall, sequences shared a similar structure among orthologous groups identified in the phylogeny ( Supplementary Figure S1 and Figure 2 ). Motifs 1 and 2, referring to the DOF domain, are present in all sequences; why they appear separately is not well understood, but it is a recurrent phenomenon in the prediction of conserved DOF sequence motifs through MEME [ 61 , 62 ]. From the reconstruction of phylogenetic relationships, eight E. uniflora DOF genes were not grouped into orthologous groups.…”

Eugenia uniflora is a Brazilian native plant species with great ecological and economic importance. It is distributed throughout the Atlantic forest, where two distinct populations show local adaptation to the contrasting conditions of restinga and riparian forest. Among various TFs described in plants, the DOF TF family has been reported to affect flowering and vascular development, making them promising candidates for characterization in E. uniflora. In this study, 28 DOF genes were identified by a genome-wide analysis, of which 20 were grouped into 11 MCOGs by Bayesian phylogeny, suggesting a shared functionallity between members. Based on RNA-seq experiments, we have detected eight drought responsive genes, and SNPs identification revealed population unique polymorphisms, implying a role in local adapatation mechanisms. Finally, analysis of conserved motifs through MEME revealed 15 different protein motifs, and a promoter region analysis returned 40 enriched TF binding motifs, both reporting novel biological functions circa the DOF gene family. In general, the DOF family is found to be conserved both in sequence and expression. Furthermore, this study contributes to both DOF literature and the genetic exploration of native species, elucidating their genetic potential and bringing to light new research topics, paving the way to future studies.
