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