Figure 1: Phloem and xylem transport in plants. Plants possess different transport systems that can be classified according to the distance and the direction of transport. To assure that the ...

Researchers have combined traditional genetic approaches with 3-D reconstructions from scanning electron microscopy to discover and characterize genes regulating the development of plant sieve ...

With our sustained high summer temperatures plants need a continuous source of water. Water moves from the soil into and throughout a plant delivering water and nutrients via a pipe-like vascular ...

Plant Physiology, Vol. 138, No. 2, Arabidopsis Special Issue (Jun., 2005), pp. 803-818 (16 pages) The growth of secondary xylem and phloem depends on the division of cells in the vascular cambium and ...

Researchers at the University of Helsinki have discovered a mechanism that allows plants to regulate the ratio of produced wood (i.e. xylem) and phloem. Both tissues are formed by the vascular cambium ...
