Various classes of plant pathogenesis-related proteins have been identified in the past several decades. PR-Q, a member of the PR3 family encoding chitinases, has played an important role in regulating plant resistance and preventing pathogen infection. In this paper, we functionally characterized  NtPR-Q  in tobacco plants and found that the overexpression of  NtPR-Q  in tobacco Yunyan87 resulted in higher resistance to  Ralstonia solanacearum  inoculation. Surprisingly, overexpression of  NtPR-Q  led to the activation of many defense-related genes, such as salicylic acid (SA)-responsive genes  NtPR1a/c ,  NtPR2  and  NtCHN50 , JA-responsive gene  NtPR1b  and ET production-associated genes  NtACC Oxidase  and  NtEFE26 . Consistent with the role of  NtPR-Q  in multiple stress responses,  NtPR-Q  transcripts were induced by the exogenous hormones SA, ethylene and methyl jasmonate, which could enhance the resistance of tobacco to  R. solanacearum . Collectively, our results suggested that  NtPR-Q  overexpression led to the up-regulation of defense-related genes and enhanced plant resistance to  R. solanacearum  infection.
