Evolutionary study of the isoflavonoid pathway based on multiple copies analysis in soybean.

ABSTRACT:

Background

Previous studies suggest that the metabolic pathway structure influences the selection and evolution rates of involved genes. However, most of these studies have exclusively considered a single gene copy encoding each enzyme in the metabolic pathway. Considering multiple-copy encoding enzymes could provide direct evidence of gene evolution and duplication patterns in metabolic pathways. We conducted a detailed analysis of the phylogeny, synteny, evolutionary rate and selection pressure of the genes in the isoflavonoid metabolic pathway of soybeans.

Results

The results revealed that 1) only the phenylalanine ammonia-lyase (PAL) gene family most upstream from the pathway preserved all of the ancient and recent segmental duplications and maintained a strongly conserv
