A secreted factor inducs cell expansion and formation of metaxylem-like tracheary elements in xylogenic suspension cultures of zinnia.... These effects include (a) induction of early cell expansion, (b) delay in differentiation by 48 h or more, (c) reduction in the synchrony of differentiation, and (d) early formation of very large, metaxylem-like tracheary elements....
Anatomy of seedling roots of tropical maize (zea mays l.) cultivars at low water supply... Anatomy of root metaxylem vessels may influence the capacity for water transport and respective genotypic differences might be useful for selection purposes....
Vulnerability of protoxylem and metaxylem vessels to embolisms and radial refilling in a vascular bundle of maize leaves... A vascular bundle in maize consisted of a protoxylem vessel with helical thickenings between two metaxylem vessels with single perforation plates and nonuniformly distributed pits....
Transcription switches for protoxylem and metaxylem vessel formation... VASCULAR-RELATED NAC-DOMAIN6 (VND6) and VND7 can induce transdifferentiation of various cells into metaxylem- and protoxylem-like vessel elements, respectively, in Arabidopsis and poplar....
