Phylogeny, structural evolution and functional diversification of the plant PHOSPHATE1 gene family: a focus on Glycine max.

ABSTRACT:

Background

PHOSPHATE1 (PHO1) gene family members have diverse roles in plant growth and development, and they have been studied in Arabidopsis, rice, and Physcomitrella. However, it has yet to be described in other plants. Therefore, we surveyed the evolutionary patterns of genomes within the plant PHO1 gene family, focusing on soybean (Glycine max) due to its economic importance.

Results

Our data show that PHO1 genes could be classified into two major groups (Class I and Class II). Class I genes were only present and expanded in dicotyledonous plants and Selaginella moellendorffii; Class II genes were found in all land plants. Class I sequence losses in other lineages may be attributed to gene loss after duplication events in land plant evolution. Introns varied from 7 to 1
