Orthology Prediction and Phylogenetic Analysis Methods in Plants.

Abstract

In this chapter, we outline a pipeline for ortholog prediction and phylogenetic analysis in plants. This computational pipeline uses algorithms from different software to enable bioinformatic-beginner biologists to predict orthologs that can be shared with many distinct plant nonmodel and model species and identify gene loss events. Prediction of orthologs allows (1) investigation of the evolutionary relationships of plant genomes, (2) discovery of their origin, function, and (3) the impact of their adaptability to the environment.We developed a pipeline to fit, not only eukaryote but also prokaryote organisms, with small or large genomes. All results acquired from the orthologs predication will enable phylogenetic tree construction, using gene and species (phylogenomic) phylogeny approaches.
