The vascular system of the plant is a network of cells that interconnects all major plant organs. A vast body of literature describes both the patterns of vascular development and a variety of experimental approaches to study factors controlling vascular development (for example (Shininger, 1979; Sachs, 1981; Aloni, 1987), however the use of molecular genetic approaches using Arabidopsis is a relatively recent entry. The vast majority of Arabidopsis references cited in this review were published within the last five years, and the significance of this work is reflected by the publication of several recent reviews on vascular development that prominently feature work on Arabidopsis (Nelson and Dengler, 1997; Berleth and Mattsson, 2000; Berleth et al., 2000; Dengler and Kang, 2001; Ye, 2002). In this review, we focus on two major aspect of vein patterning: the apical/basal pattern (found in stems and roots); and the reticulate patterns (found in all broad flat organs) (Figure 1). The vascular system is composed of two tissues, xylem and phloem, which function to transport water and solutes, or sugars, respectively. Each of these tissues is composed of multiple specialized cell types. In comparison to information gained from the zinnia in vitro system for tracheary element differentiation from leaf mesophyll cells (see Fukuda, 1997; Roberts and McCann, 2000) for review), work to date using Arabidopsis has not contributed greatly to our knowledge of vascular cell type differentiation. Consequently, only a brief description of vascular cell types is included (below) It is considered that the molecular genetic analysis of vascular cell type differentiation is likely to be a productive area of future work involving Arabidopsis. Figure 1. Vein Pattern in an Arabidopsis Seedling. A cleared wild type (L.er) 11 day old seedling, photographed using dark-field optics. The tracheary elements refract light, and show up as bright white lines. Note the reticulated patterns of veins in the cotyledons and leaves, and the linear pattern in the hypocotyl and roots.
