A defining feature of higher plants such as Arabidopsis thaliana is the sophisticated vascular transport system throughout the entire plant organism. This vascular system consists of two conducting tissues, xylem and phloem. The phloem consists primarily of two highly specialized cell types: sieve elements (SE) and companion cells (CC). Closely associated with the sieve elements are the companion cells, which derive from the same precursor cells. The vasculature of higher plants – phloem, xylem, and procambium – derives from a discrete population of stem cells, the vascular meristem. Sieve elements (SE), also known as sieve tube elements, form the conductive part of the phloem. As for companion cells (CC), they originate from phloem precursor cells in the procambium. The evolution of vasculature presumably occurred simultaneously and independently across the plant kingdom/
