Abstract
Purple acid phosphatase (PAP) is important for phosphorus assimilation and in planta redistribution. In this study, seven Brassica napus PAP12 (BnPAP12) genes orthologous to Arabidopsis thaliana PAP12 (AtPAP12) are isolated and characterized. NCBI BLASTs, multi-alignments, conserved domain prediction, and featured motif/residue characterization indicate that all BnPAP12 members encode dimeric high molecular weight plant PAPs. BnPAP12-1, BnPAP12-2, BnPAP12-3 and BnPAP12-7 (Group I) have six introns and encode 469-aa polypeptides structurally comparable to AtPAP12. BnPAP12-4 and BnPAP12-6 (Group II) have seven introns and encode 526-aa PAP12s. Encoding a 475-aa polypeptide, BnPAP12-5 (Group III) is evolved from a chimera of 5′ part of Group I and 3′ part of Group II. Sequence characterization and Southern detection suggest that there are about five BnPAP12 alleles. Homoeologous non-allelic fragment exchanges exist among BnPAP12 genes. BnPAP12-4 and BnPAP12-6 are imprinted with a Tourist-like miniature inverted-repeat transposable element (MITE) which is tightly associated with a novel minisatellite composed of four 36-bp tandem repeats. Existing solely in B. rapa/oleracea lineage, this recently evolved MITE-minisatellite twin structure does not impair transcription and coding capacity of the imprinted genes, and could be used to identify close relatives of B. rapa/oleracea lineage within Brassica. It is also useful for studying MITE activities especially possible involvement in minisatellite formation and gene structure evolution. BnPAP12-6 is silent in transcription. All other BnPAP12 genes basically imitate AtPAP12 in tissue specificity and Pi-starvation induced expression pattern, but divergence and complementation are distinct among them. Alternative polyadenylation and intron retention also exist in BnPAP12 mRNAs.
