Phylogenetic analysis of the Asp-rich protein genes. The Neighbor joining tree based on p-distance and pairwise deletions of gaps shows phylogenetic relationship among the putative Asp-rich proteins identified in different species. The numbers at the branch points indicate bootstrap support values above 50% (1,000 replicates). Based on Neighbor joining clustering, Asp-rich proteins were tentatively grouped into seven main families, from A to G. The citrus Asp-rich proteins are highlighted.
