Fig. 2 in Sites of biosynthesis and storage of Taxol in Taxus media (Rehder) plants: Mechanism of accumulation

Fig. 2. Taxol localization and storage. (A) Transverse section of a Taxus plant stem showing the location of Taxol-containing HB (red-stained droplets) within the wood and phloem in comparison to (B) close up view in the vascular bundle (VB) of a root section and (C) close up view in the vascular bundle (VB) of a needle (Taxus leaf) section. (D) and (E) Close up views in the wood and phloem, respectively, to show the distribution of Taxol-containing HB within Taxus stem sections. (F) Pearson's correlation between Taxol content and the number of HB within different plant samples (Pearson's correlation, r2 = 0.77).
