Zinnia tracheary element

Fig 6 Immunodot-blots of culture-medium aliquots sampled during the time-course of differentiation of Zinnia mesophyll cells to tracheary elements and dotted on to nitrocellulose. I = Inductive medium, N = Non-inductive medium. The JIM 7 epitope dries in a series of concentric rings on the nitrocellulose, indicating a mixed population of pectins. During the time-course, the rhamnose content of inductive culture medium increases dramatically compared with non-inductive medium.
