Fig. 55 in The scope of flavin-dependent reactions and processes in the model plant Arabidopsis thaliana
Fig. 55. Reduction of NADP þ by ferredoxin-dependent reductase. The FAD cofactor is reduced in two consecutive steps by single electron transfer from reduced ferredoxin. The two-electron reduced (hydroquinone) FAD subsequently transfers a hydride to NADP+ to yield NADPH. The reaction may also run in the reverse direction, i.e. NADPH serves as the reductant to generate reduced ferredoxin, which is used to drive a number of biochemical reactions.
Fig. 48 in The scope of flavin-dependent reactions and processes in the model plant Arabidopsis thaliana
Fig. 48. Reaction catalyzed by sarcosine/pipecolate oxidase. A. Oxidation of sarcosine generates the imine, which spontaneously hydrolyzes to glycine and formaldehyde. In contrast to mammalian sarcosine oxidase, the A. thaliana enzyme does not utilize tetrahydrofolate to capture the reactive formaldehyde. B. Oxidation of pipecolate to Δ1-piperideine-6-carboxylate. In both reactions the reoxidation of the reduced FAD occurs by dioxygen leading to the production of hydrogen peroxide (not shown).
Fig. 43 in The scope of flavin-dependent reactions and processes in the model plant Arabidopsis thaliana
Fig. 43. Reaction of N-monooxygenation by flavin-containing monooxygenases. The single flavin-containing monooxygenase belonging to clade 1 is involved in pathogen defense, as it catalyzes the N-oxygenation of pipecolic acid to NHP, a key metabolite required for the initiation of pathogen-induced immune response (Hartmann et al., 2018).
Fig. 46 in The scope of flavin-dependent reactions and processes in the model plant Arabidopsis thaliana
Fig. 46. Reactions catalyzed by NADPH oxidases. The two electrons delivered by NADPH are either used for the reduction of dioxygen to hydrogen peroxide (top reaction) or the reduction of two molecules of dioxygen to two molecules of superoxide (bottom reaction).
Fig. 5 in The scope of flavin-dependent reactions and processes in the model plant Arabidopsis thaliana
Fig. 5. Reaction of glycerol 3-phosphate dehydrogenase. The secondary alcohol group is oxidized to the keto-group (shown in red) generating dihydroxyacetone phosphate, which is further converted by triose phosphate isomerase, a glycolytic enzyme, to glyceraldehyde 3-phosphate. The reduced FAD is reoxidized by membrane-associated CoQ and thus the electrons enter the mETC. (For interpretation of the references to colour in this figure legend, the reader is referred to the Web version of this article.)
Fig. 1 in The scope of flavin-dependent reactions and processes in the model plant Arabidopsis thaliana
Fig. 1. Association with other cofactors (A) and mode of flavin binding (B). (A) In 36 A. thaliana flavoenzymes additional iron-dependent cofactors are part of the functional enzyme and contain either heme (18), iron-sulfur (Fe–S) clusters (10) or a combination of the molypdocofactor (Moco) with 2Fe–2S clusters (6) or heme (2). In acetohydroxyacid synthase the FAD cofactor is associated with thiamine pyrophosphate (TPP). (B) In most cases the FMN and FAD cofactor is bound non-colavently (FMN = 44 and FAD = 180), while mono-covalent (exclusively to the 8α-position of FAD) and bi-covalent linkage (to the 6- and 8α-position of FAD) are comparatively rare (9 and 10.3% of the FAD-containing flavoenzymes, respectively). The insert shows the isoalloxazine ring with the numbering scheme and indicates the positions of covalent attachment. The FMN cofactor is not involved in covalent bond formation in the flavoenzymes of A. thaliana.
Fig. 2. The cyp71a12 in Metabolite profiling reveals a role for intercellular dihydrocamalexic acid in the response of mature Arabidopsis thaliana to Pseudomonas syringae
Fig. 2. The cyp71a12/cyp71a13 mutant supports higher levels of Pseudomonas syringae at 7 weeks post-germination compared to Col-0 and cyp71b15. P. syringae pv. Tomato levels were quantified 3 days after inoculation by pressure infiltration of fully expanded rosette leaves of (A) 3- or (B) 7- week-old plants. Values represent the mean ± standard deviation of three sample replicates (n = 3) consisting of 8 plants each. Different letters indicate statistically significant differences (one-way ANOVA, Tukey's honestly significant difference [HSD], P <0.05).
Fig. 2. Ubiquinone-9 in 3-O-glycosylation of kaempferol restricts the supply of the benzenoid precursor of ubiquinone (Coenzyme Q) in Arabidopsis thaliana
Fig. 2. Ubiquinone-9 levels in A. thaliana rosette leaves. A. thaliana seedlings were axenically fed for 24h with 0 (control), 2, 10, 125 and 250 μM of 4- hydroxybenzoate. Data represent the means of 5 biological replicates ± SE. P values from an analysis of variance between each mutant and the wild-type reference are indicated above the bars. Asterisks indicate significant differences between the control and the 4-hydroxybenzoate-fed plants as determined by variance analysis (P <α = 0.1).
Fig. 2 in Melatonin mitigates UV-B stress via regulating oxidative stress response, cellular redox and alternative electron sinks in Arabidopsis thaliana
Fig. 2. Activities of different SOD isoenzymes (90 and 180 min) and expressions of genes encoding different SODs (90 min) of UV-B treated A. thaliana plants with or without 10 μM melatonin supplement. Experiments were repeated two times, and each data point was the mean of three replicates (n = 6). Significant differences (P <0.05) were marked with different letters (a–d) in the charts.

Fig. 6. Expressions of glutathione biosynthesis (GSH1 and GSH2) and degradation (OXP1 and GGT1) related genes of UV-B treated (90 min) A. thaliana plants with or without 10 μM melatonin supplement. Experiments were repeated two times, and each data point was the mean of three replicates (n = 6). Significant differences (P <0.05) were marked with different letters (a–d) in the charts.
