Genome-Wide Identification and Analysis of Gene Family in L. (Myrtaceae).

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 TF family has been reported to affect flowering and vascular development, making them promising candidates for characterization in . In this study, 28 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 gene family. In general, the family is found to be conserved both in sequence and expression. Furthermore, this study contributes to both 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.
