Fig. 7 in Tissue specificity of (E)-β-farnesene and germacrene D accumulation in pyrethrum flowers

Fig. 7. NADI and aniline blue staining of cross sections of young T. cinerariifolium flower peduncles. (A and B) NADI staining of two cross sections of S0 and S1 upper flower peduncles. The positive NADI stained oil droplets are pointed out by white arrows. (C) Cross section of S2 flower peduncle stained by NADI reagent coupled with aniline blue staining observed under the bright light. (D) Cross section of the same S2 flower peduncles as in C observed under the UV light, callose in the sieve elements was stained by aniline blue and indicated by white arrowhead. The white arrows point to NADI stained oil droplets in C that appear to be outside the cell wall as indicated by red arrows in D. Ph, phloem; Xy, xylem; Co, cortex; Pi, pith; Se, sieve element..
