Bioinformatic Analysis of Strawberry PTOX Gene

摘要

PTOX has always been known as a key factor of defense response in plant testa. Recent studies show that The plastid terminal oxidase (plastid terminal oxidase, PTOX) is a nuclear encoded, plastid located plastid quinoxone oxidoreductase (plastid quinone oxidase). PTOX is the terminal oxidase of the plant chloroplast respiration. In this research we chosen PTOX gene of 9 kinds species, downloaded their nucleotide and protein sequence from NCBI as the research object, found strawberry PTOX gene via bioinformation analyses, constructed phylogenetic tree. At the same time, we analyzed the strawberry PTOX gene of physical and chemical properties and its protein structure and so on. The phylogenetic tree showed that strawberry and Malus x domestica closest relative. By the protein prediction, we found that the protein owed one proper signal peptide without obvious transmembrane regions.
