Resumen:
The evolution of spermatophyte plants involved fundamental changes in cell wall structure and function which resulted from diversification of carbohydrates and proteins. Cell wall proteomic analyses identified a novel family of proteins of yet unknown function, the DUF642 (Domain of Unknown Function 642) proteins. To investigate the evolution of the DUF642 gene family, 154 gene sequences from 24 plant species were analyzed, and phylogenetic inferences were conducted using the Maximum Likelihood and Bayesian Inference methods. Orthologous genes were detected in spermatophyte species and absent in non-seed known plant genomes. Protein sequences shared conserved motifs that defined the signature of the family. Distribution of conserved motifs indicated an ancestral intragenic duplication event. Gene phylogeny documented paleoduplication events originating three or four clades, depending on root position. When based on mid-point rooting, it retrieved four monophyletic clades: A, B, C, and
