Endophyte consortium treatment improved photosynthetic efficiency and phosphate nutrition in S. nigrum. (A) Total chlorophyll content in plant leaves was compared between endophyte consortium-treated plants and uninoculated plants grown in the presence or absence of 25 ppm As. ***P < 0.0001 (endophyte-treated vs uninoculated; two-way ANOVA with Tukey’s post-hoc test); n = 9 (3 leaves/plant). (Df for As:1, for endophytes:1, for interaction:1, error:32). (B and C) Photosynthetic efficiency of endophyte consortium-treated plants was compared with untreated plants grown in the presence of As, represented by Fv/Fm ratio (B) and the radar plot (C). ***P < 0.0001 (unpaired two-tailed t-test); n = 9 (3 leaves/plant). (D) The total phosphate content of endophyte consortium treated and uninoculated plants grown in presence of 25 ppm As was measured by ICP-OES 4wpi. n = 9 (each in 3 experimental replicates). ***P < 0.0001(unpaired two-tailed t-test). Data are represented as mean ± SEM.
