Figure 5.

The high ascorbate MIOX4 line is photosynthetically more efficient. (a) Transcripts related to photosystem I and II (PSI, PSII) were up‐regulated (indicated by red squares) in MIOX4 OE line compared to WT. Figure was obtained using MapMan V3.5.1R2. (b) Over‐expression of transcripts related to PSII center was validated using RT‐qPCR. Data are means ± SEM (n = 3). (c,d) Photosystem II efficiency (ΦII efficiency) and proton motive force (vH⁺) were significantly higher in MIOX4 OE line compared to WT from 21 to 28 days after germination. Data are means ± SEM (n = 15). **indicates p < .01, ***indicates p < .001, and ****indicates p < .0001 at 0.05 significance level
