Wood Decay by Brown-Rot Fungi: Changes in Pore Structure and Cell Wall Volume

Sweetgum (Liquidambar styraciflua L.) wood blocks were decayed by Postia (= Poria) placenta in soilblock cultures. Decay was terminated at various weight losses, and the pore volumes available to four low molecular weight molecules, (water, 4 Å,; glucose, 8 Å,; maltose, 10 Å; and raffinose, 128,) and three dextrans (Mr 6,000, 38 Å; 11,200, 51 Å; and 17,500, 61 Å) were determined by the solute e...

Wood Cell-Wall Structure Requires Local 2D-Microtubule Disassembly by a Novel Plasma Membrane-Anchored Protein

Plant cells have evolved cortical microtubules, in a two-dimensional space beneath the plasma membrane, that regulate patterning of cellulose deposition. Although recent studies have revealed that several microtubule-associated proteins facilitate self-organization of transverse cortical microtubules, it is still unknown how diverse patterns of cortical microtubules are organized in different x...

Lignification 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...

The Structure of the Yeast Cell Wall

The autolytic release of fl-fructofuranosidase (EC 3.2.1.26) and acid phosphatase (EC 3.1.3.2) from the cell wall of yeast was studied under different organic solvents and with a variety of pII and temperature conditions. /3Fructofuranoeidase (but not acid phosphatase) was found to be a convenient marker for studying changes in the wall structure. The ethyl acetate-treated cell was characterize...
