Anatomy of xylem and phloem in stems and roots of Populus sibirica and Ulmus pumila from semi-arid steppe in Mongolia

open access: yesLes, 2023
The present study focuses on the cambium and the anatomy of secondary tissues (xylem – wood and phloem) of Siberian poplar (Populus sibirica) and Siberian elm (Ulmus pumila) grown in a plantation in the semi-arid Mongolian steppe.

Molecular mechanisms for vascular development and secondary cell wall formation

open access: yesFrontiers in Plant Science, 2016
Vascular tissues are important for transporting water and nutrients throughout the plant and as physical support of upright growth. The primary constituents of vascular tissues, xylem and phloem, are derived from the meristematic vascular procambium and ...

Arabidopsis NAC domain proteins, VND1 to VND5, are transcriptional regulators of secondary wall biosynthesis in vessels. [PDF]

open access: yesPLoS ONE, 2014
One of the most prominent features of xylem conducting cells is the deposition of secondary walls. In Arabidopsis, secondary wall biosynthesis in the xylem conducting cells, vessels, has been shown to be regulated by two VASCULAR-RELATED NAC-DOMAIN (VND)

EFFECT OF 2,6-DICHLOROBENZONITRILE (DCB) ON SECONDARY WALL DEPOSITION AND LIGNIFICATION IN THE STEM OF HIBISCUS CANNABINUS L. [PDF]

open access: yesJournal of Plant Development, 2013
Light and electron microscopic studies were carried out on the secondary xylem of actively growing shoots of Hibiscus cannabinus treated with cellulose synthesis inhibitor 2,6-dichlorobenzonitrile (DCB). Treatment with 20µM DCB induced differentiation of

Transcriptional Regulation of Xylem Development and Secondary Cell Wall Composition [PDF]

open access: yes, 2023
The plant vascular system is comprised of specialized tissues known as xylem and phloem. The interconnected network of xylem vessel elements, with their elongated structures and reinforced secondary cell walls, form a hydraulic system that enables ...

Microtubules, MAPs and Xylem Formation [PDF]

open access: yes, 2010
Xylem is essential for transporting water and minerals transport as well as for mechanical resistance against gravity. These key characteristics of xylem are enabled by the development of specific secondary cell walls which exhibit different patterns of ...

The Parenchyma of Secondary Xylem and Its Critical Role in Tree Defense against Fungal Decay in Relation to the CODIT Model

open access: yesFrontiers in Plant Science, 2016
This review examines the roles that ray and axial parenchyma (RAP) plays against fungal pathogens in the secondary xylem of wood within the context of the CODIT model (Compartmentalization of Decay in Trees), a defense concept first conceived in the ...

The vascular cambium of trees and its involvement in defining xylem anatomy [PDF]

open access: yes, 2017
The growth of perennial plants from tall upright trees up to small prostrate dwarf shrubs is a complex of interlinked processes resulting in a three-dimensional body whereby meristematic tissues play a crucial role. Among the various fractions
