Alfalfa Stem Tissues: Cell Wall Deposition, Composition, and Degradability
maturation on stem quality may have the largest potential benefit. Declining cell wall degradability of alfalfa (Medicago sativa L.) The tools of molecular biology offer the potential of stems with maturation limits the nutritional value of alfalfa for ruminants. This study characterized changes in cell wall concentration, altering the development of alfalfa stems in very precise composition, a...
متن کاملPlant cell wall lignification and monolignol metabolism
Plants are built of various specialized cell types that differ in their cell wall composition and structure. The cell walls of certain tissues (xylem, sclerenchyma) are characterized by the presence of the heterogeneous lignin polymer that plays an essential role in their physiology. This phenolic polymer is composed of different monomeric units - the monolignols - that are linked together by s...
متن کاملLignification in poplar tension wood lignified cell wall layers.
The lignification process in poplar tension wood lignified cell wall layers, specifically the S(1) and S(2) layers and the compound middle lamella (CML), was analysed using ultraviolet (UV) and transmission electron microscopy (TEM). Variations in the thickness of the gelatinous layer (G-layer) were also measured to clarify whether the lignified cell wall layers had completed their lignificatio...
متن کاملVisualization of plant cell wall lignification using fluorescence-tagged monolignols
Lignin is an abundant phenylpropanoid polymer produced by the oxidative polymerization of p-hydroxycinnamyl alcohols (monolignols). Lignification, i.e., deposition of lignin, is a defining feature of secondary cell wall formation in vascular plants, and provides an important mechanism for their disease resistance; however, many aspects of the cell wall lignification process remain unclear partl...
متن کاملWall extensibility and cell hydraulic conductivity decrease in enlarging stem tissues at low water potentials.
Measurements with a guillotine psychrometer (H Nonami, JS Boyer [1990] Plant Physiol 94: 1601-1609) indicate that the inhibition of stem growth at low water potentials (low psi(w)) is accompanied by decreases in cell wall extensibility and tissue hydraulic conductance to water that eventually limit growth rate in soybean (Glycine max L. Merr.). To check this conclusion, we measured cell wall pr...
