Abstract
For centuries, humans have grown and used structures based on vascular tissues in plants. One could imagine that life would have developed differently without wood as a resource for building material, paper, heating energy, or fuel and without edible tubers as a food source. In this review, we will summarise the status of research on Arabidopsis thaliana vascular development and subsequently focus on how this knowledge has been applied and expanded in research on the wood of trees and storage organs of crop plants. We will conclude with an outlook on interesting open questions and exciting new research opportunities in this growing and important field.

Vascular development in Arabidopsis thaliana has been a topic of intensive research for decades
(SACL) protein family, which affects the TMO5–LHW interaction that acts on xylem differentiation and cytokinin biosynthesis [12,13,30,31,32,33]
Summary
In the 19th century, the variety of vascular arrangements in form of different stele types attracted the interest of researchers. The structures in different species and organs are of diverse build, they share some of the underlying regulatory mechanisms and their main functions for the plant. They enable plants to transport water, nutrients, assimilates, as well as signalling molecules, and provide stability to the plant body. In this short review, we will focus on Arabidopsis thaliana as an example of an herbaceous species and as a commonly used model plant, in which many of the regulatory pathways for vascular development and arrangement have been elucidated. Research on vascular development and expansion involving various species and growth forms is an excellent example of how basic research and applied research can work hand in hand to promote the growth of scientific knowledge and its application
