Bioinformatics Analysis of the Phytoene Dehydrogenase Gene in Potato (Solanum tuberosum)

摘要

Phytoene Dehydrogenase (PDS) is an important enzyme in carotenoid biosynthesis. Here, the Solanum tuberosum PDS (StPDS) gene sequences were obtained from Spud DB database, and preformed for bioinformatics analysis. The StPDS gene mapped to chromosomes 3, and contains an open reading frame of 1,752 bp that encodes a 583-amino acid protein with a calculated molecular mass of 64.97 kD and an isoelectric point (pI) of 6.41. Subcellular localization predicted the StPDS gene was in the chloroplast. The conserved domain of the StPDS protein is PLN02612. The PDS protein is most closely related to Solanum pennellii. The findings of the present study provide a molecular basis for the elucidation of PDS gene function in potato.
