From: Combinatorial analysis of lupulin gland transcription factors from R2R3Myb, bHLH and WDR families indicates a complex regulation of chs_H1 genes essential for prenylflavonoid biosynthesis in hop (Humulus LupulusL.)

Figure 10

Simplified scheme of P chs _H1 (I) and P chs 4 (II) activation with combinations of hop TFs as observed in heterologous system of N. benthamiana. The basic scheme was accommodated from Baudry et al. [27]. 3-D model of HlWDR1 in the scheme was obtained using SWISS-MODEL Workspace (see Methods). (a) the whole ternary complexes consisting of MYB, bHLH and WDR TFs; (b) bHLH and WDR binary combination; (c) MYB and bHLH combinations; (d) Myb and WDR combinations; (e) "direct" independent action of hop TFs that does not require complex with analyzed hop TFs; (f) inhibitory effect of HlMyb7. The figure is not in scale, TFs are assumed to interact with promoter binding sites. Binding boxes are not shown in the scheme. The weak signals close to background interactions are not considered in the scheme.
