Pectinmethylesterases (PME) and Pectinmethylesterase Inhibitors (PMEI) Enriched during Phloem Fiber Development in Flax (Linum usitatissimum)
Figure 1
Location in the stem of the tissues used for the experiments used in this study.
Plants were 5 weeks old, in vegetative stage, and their height from the hypocotyls was between 46 to 48 cm. Tissues were harvested and rapidly frozen with liquid nitrogen for RNA and protein extraction. 100 µm (points A to E) and 10 µm (point SA) cross sections. Bar: 50 µm. e: epidermis, f: fibers, p: phloem.
