Bioinformatic Analysis of Strawberry NDH-H Gene

摘要

NDH-H has always been known as a key factor of Hydrogen ion metabolism pathway in plant testa. Recent studies show that chlororespiration and cyclic electron flow mediated by NDH may coordinate to alleviate the over-reduction of stroma, thus to keep operation of C02 assimilation at certain extent under heat stress condition. In this research we chosen NDH-H gene of 13 kinds species, downloaded their nucleotide and protein sequence from NCBI as the research object, found strawberry NDH-H gene via bioinformation analyses, constructed phylogenetic tree. At the same time, we analyzed the strawberry NDH-H gene of physical and chemical properties and its protein structure and so on. The phylogenetic tree showed that strawberry and Malus x domestica were closest relative. By the protein prediction, we found that the protein owed one proper signal peptide without obvious transmembrane regions.
