Effects of TOR inhibition on the photosynthetic capacity of M. hupehensis plants under low N stress. (A) Net photosynthesis (Pn). (B) Stomatal conductance (Gs). (C) Intercellular CO2 concentration (Ci). (D) Maximum potential PSII efficiency (Fv/Fm). (E) Chlorophyll fluorescence images of plants in different treatments. Data are mean ± standard error of 10 replicate samples. Different lowercase letters indicate statistically significant differences between treatments according to Tukey’s multiple range test (P < .05). NC, plants with no treatment; 0A, low N stress treatment (0.2 mM N); 0.5A–10A: low N stress with 0.5 μM (0.5A), 1 μM (1A), 2.5 μM (2.5A), 5 μM (5A), and 10 μM (10A) AZD8055 treatments.
