Figure 4

Expression profile of the most relevant candidate genes identified over the two growing seasons. Expression profiles for 2008 are on the left, whereas those for 2009 are on the right. Squares and red lines are used for the “V+” family for the non-irrigated treatment and triangles and orange lines are used for the “V-” family for the non-irrigated treatment. Squares and dark blue lines are used for the “V+” family for the irrigated treatment and triangles and light blue lines are used for the “V-” family for the irrigated treatment. Error bars represent the standard deviation (N = 3). Results of two-way ANOVA are also indicated above each sampling point. Abbreviations are as follows: T: treatment effect, G: family effect, TG: interaction effect. * P value < 0.01, **P value < 0.001 and ***P value < 0.0001.
