Bioinformatic Analysis of Strawberry PGR5 Gene

摘要

PGR5 has always been known as a key factor of Heat response in plant testa. Recent studies show that PGR5 (proton gradentregulation 5) is a proton gradient regulatory protein, which transfers cycle electronic I encoding thylakoid membrane proteins and optical systems, and helps to induce pH heat dissipation. In this research we chosen PGR5 gene of 9 kinds species, downloaded their nucleotide and protein sequence from NCBI as the research object, found strawberry PGR5 gene via bioinformation analyses, constructed phylogenetic tree. At the same time, we analyzed the strawberry PGR5 gene of physical and chemical properties and its protein structure and so on. The phylogenetic tree showed that strawberry and Morus notabiliswere closest relative. By the protein prediction, we found that the protein owed one proper signal peptide without obvious transmembrane regions.
