Fig. 5 in Tissue specificity of (E)-β-farnesene and germacrene D accumulation in pyrethrum flowers

Fig. 5. NADI staining for longitudinal sections of flower of T. cinerariifolium. (A) NADI staining for disk floret of S1 flower. (B) NADI staining of the upper section of a disk floret of S1 flower. (C) NADI staining of the upper section of a disk floret of an S2 flower showing the bilobed stained stigma on top of a short style. (D) NADI staining of longitudinal sections of S3 flower. (E) NADI staining of the upper sections of disk florets of S4 flower. Df, disk floret; Rec, receptacle; Sty, style; An, anther; Ac, anther cylinder; Sti, stigma; Co, corolla; GT, glandular trichome. Pure GD, EβF and pyrethrins were individually stained by NADI reagent and shown in A. The white arrows point to the positive NADI stained oils. The inset picture in D represents the top view of the flower.
