Multiple facets of laticifer cells.

In the latex-bearing plants, the laticiferous system is the tubing structure that contains the latex and is constituted of living cells (laticifers). While laticifers are present only in a small percentage of the flowering plant species, they represent a type of specialized tissue within the plant where a myriad of metabolites are synthesized, some of them of considerable commercial importance. In this mini-review we synopsize the present knowledge about laticifer cells and discuss about their particular features as well as some evolutionary and ecophysiological cues and the potential exploitation of the knowledge generated around this peculiar type of plant cell. We illustrate some of these questions with the experience in Euphorbia lathyris laticifers and latex.
