Pathology of the Xylem

2002
This chapter is probably the most difficult one for me to write, because, in doing so, I have to step outside my field of expertise more often than I like. Yet, I feel that it is necessary to build a bridge between those of us who are concerned with xylem structure and the ascent of sap, and those plant pathologists who are interested in xylem ...

Immunolocalization in Secondary Xylem of Populus

2017
Immunolocalization can be used to precisely visualize the location of specific proteins, cell wall components, or any other molecules within cells or tissues for which specific antibodies are available. Here we describe an immunolocalization protocol for tissue sections of woody Populus stems.

The xylem pathway

1978
For transport over relatively short distances the cell to cell pathway is adequate but, in higher plants in particular, long-distance transport of water and dissolved solutes is through the specialized conduits of the xylem and of the phloem (see p. 40).

Freezing Stress in Tree Xylem

2016
Freezing in plant xylem is a complex process affecting living and dead components. This book chapter gives a brief overview of methods for analyzing freezing dynamics and tissue damage and focuses on the effects of freezing stress in the xylem symplast and apoplast.

Methods for Xylem Sap Collection

2012
Xylem and phloem are essential for the exchange of solutes and signals among organs of land plants. The synergy of both enables the transport and ultimately the partitioning of water, nutrients, metabolic products and signals among the organs of plants. The collection and analysis of xylem sap allow at least qualitative assumptions about bulk transport

Carbohydrate Composition Analysis in Xylem

2017
Gas chromatography-mass spectrometry (GC-MS) is a widely applied technique in carbohydrate composition analysis due to high accuracy and repeatability. As cell walls are the major carbohydrate pool in xylem tissues, the measurement of carbohydrate composition essentially constitutes an analysis of wall residues.

Bioenergetic strategy of a xylem-feeder

Journal of Insect Physiology, 2009
To understand the efficiency of energy flow through an organism living in a nutrient poor environment, the bioenergetics of a xylem-feeding beetle Aredolpona rubra was investigated. The larvae of different ages were kept at a constant high, constant low and seasonally variable temperature or in agar plates and agar+nitrogen plates.

Potassium Translocation into the Root Xylem

Plant Biology, 1999
Abstract: Potassium is the most abundant cation in cells of higher plants and plays vital roles in plant growth and develop ment. Since the soil is the only source of potassium, plant roots are well adapted to exploit the soil for potassium and supply it to the leaves.

Xylem parenchyma cells deliver the H2O2 necessary for lignification in differentiating xylem vessels

Planta, 2004
Lignification in Zinnia elegans L. stems is characterized by a burst in the production of H(2)O(2), the apparent fate of which is to be used by xylem peroxidases for the polymerization of p-hydroxycinnamyl alcohols into lignins. A search for the sites of H(2)O(2) production in the differentiating xylem of Z.
