2.5.1.79	xylem	in the hypocotyl as well as in the inflorescence stem, ACL5 is expressed not just broadly with respect to vasculature, but specifically in the xylem vessel elements at a strictly defined developmental stage, suggesting direct involvement of ACL5 in xylem vessel differentiation. The acl5 mutant displays severe overall inhibition of the secondary growth of the vascular tissues, dramatic alteration in the morphology of the vessel elements and complete lack of xylem fibers	697543
