Plant-parasitic nematodes respond to root exudate signals with host-specific gene expression patterns
Fig 5
Cellulose and xylan specifically upregulate expression of Pc-eng-1 and Pc-xyl, respectively.
Polynomial regression analysis establishes a significant increase in expression of Pc-eng-1 (black circle) and Pc-xyl (black square) in P. coffeae with cellulose (A) and xylan (B) concentrations respectively after 6 h exposure (P< 0.01, R2 = 0.96 and P<0.001, R2 = 0.98, respectively). Expression of Pc-pel (white triangle) remained unaffected. Values are means ± SEM (n = 4 pools of mixed stage P. coffeae) and relative to expression in water.
