Photosynthetic parameters used to assess the different responses of L693 and L661 to Pst inoculation. a, Net photosynthetic rate (P _n); b, intercellular CO₂ concentration (C _i); c, stomatal conductance (G _s). The parameters were measured once every 10 days after heading in the field, using a Li-Cor 6400. The disease had fully developed at heading, and 10 plants per genotype were used for these measurements. Bars represent the standard error, and significance was determined using an independent sample t-test. Asterisks represent significant differences as follows: **P ≤0.01 and *P ≤0.05, and Ns indicates no significant difference. Raised asterisks or the Ns label represent the differences in gene expression between L693 and L661 at each time point. Asterisks or the Ns label on the trend line represent differences in gene expression between two adjacent time points in the same genotype
