Abstract: The paper aims to have a comprehensive understanding of the evolution process and biological mechanism about the development of plant xylem. It reviews research progresses on evolution and development of xylem over the past 50 years, indicates that: xylem water- conduction cells are evolved from simple to complex, and the process of xylem development involves the regulation of factors, such as plant hormones, transcription factors, cellulose-synthesizing enzymes, microtubule and microtubule binding proteins. However, molecular mechanism of secondary cell wall deposition of different types of tracheary elements in the xylem is still unclear, which will be the focus of research on plant xylem evolution and development.
