Photoinhibition and photoinhibition-like damage to the photosynthetic apparatus in tobacco leaves induced by pseudomonas syringae pv. Tabaci under light and dark conditions

Table 1 Relative changes to carbon assimilation parameters at 3 days post Pst infection in tobacco leaves

	Pn (μmol m⁻² s⁻¹)	Gs (mmol m⁻² s⁻¹)	Ci (μmol mol⁻¹)	CE (μmol m⁻² s⁻¹)
Mock	5.8 ± 0.53a	63 ± 5.29a	225 ± 16.5b	0.0521 ± 0.006a
Pst	1.78 ± 0.23b	52 ± 6.08b	278 ± 20.6a	0.0411 ± 0.008b

The changes to net photosynthetic rate (Pn), stomatal conductance (Gs), intercellular CO₂ concentration (Ci), and carboxylation efficiency (CE) were evaluated. The mean ± SE of four replicates are shown. Different small letters present on the same column indicate significant differences at P <0.05 between different treatments
