英文摘要	As a major component of the cell wall, lignin has been suggested to play an important role in the plant defence response to various pathogens. However, how lignin is involved in plant pathogen interaction is still unclear. Here, a series of transgenic tobacco lines were cultivated with a range of differences in lignin content and composition. Evaluation of pathogen resistance in these plants indicated that lower total lignin content aggravated the severity of tobacco black shank and bacterial wilt diseases, while increased sinapyl lignin (S) alleviated the disease symptoms. The regression analysis indicated both lignin content and S lignin were positively correlated with disease resistance. These two factors had additive effects, exhibiting stronger correlation with disease resistance when they were combined. Neither guaiacyl lignin (G) nor S/G ratio showed close correlation with disease resistance. The expression of pathogenesis-related protein genes PR2 and PR3 was induced after pathogen inoculation. However, the up-regulation of PR2 and PR3 was not associated with a disease resistance-induced increase in lignin content. These data collectively suggest that both total lignin content and S lignin are main factors that contribute to the basic defence response in tobacco.
