Journal of Fujfruit production causing leaf spot disease， 175 proteins with lipoprotein signal peptide
were screened from the entire genome of X. arboricola through LipoP online program. Then informations about conserved do­
mains ，signal peptides，transmembrane domains，subcellular localizations and physicochemical properties were predicted by bioin­
formatics approach. The results showed that the lengths of 144 lipoproteins ranged from 100 to 500. Among the 175 proteins with lip­
oprotein signal peptides， only 13 proteins consisted of obvious conserved domains， and 90 proteins were located in mitochondria.
These proteins differed greatly in hydrophilic/hydrophobic amino acid residues and positions. Genetic relationship analysis was fur­
ther conducted to identify species with lipoprotein homologous to their counterparts in X. arboricola， however， the homology between
most proteins with lipoprotein signal peptides was not high.
Key words: lipoprotein signal peptide ； Xanthomonas arboricola ； genetic relationship ； bioinformatics
