Genome-wide analysis of purple acid phosphatase structure and expression in ten vegetable species.

ABSTRACT:

Background

Acquisition of external phosphorus (P) and optimisation of internal P are essential for plant growth and development, and insufficient availability of P in soils is a major challenge in agriculture. Members of the purple acid phosphatase (PAP) family of enzymes are candidates for increasing P use efficiency. Herein, we identified PAP homologs in the genomes of 10 vegetable species, along with Arabidopsis thaliana and Amborella trichopoda as references, to provide fundamental knowledge for this family.

Results

Phylogenetic analysis of protein sequences revealed nine distinct clades, indicating that functional differentiation of extant PAPs was established prior to the emergence of early angiosperms, and conserved among homologs in each clade. Analysis of transcript
