... cycle, the material was in a state different from its original state, to which it returned only partially and/or slowly. Internal ‘microstructural’ prestresses are considered as an explanation for the mechanical behaviour seen in Aristolochia macrophylla and several other plants. * e-mail: spatz...

... for computing factors of safety for plants. One method works well for individual stems or entire plants, the other is useful when dealing with a population of conspecifics exhibiting a norm of reaction. Both methods require estimates of the actual and breaking bending (or torsional) moments experienced by stems...

... concerns ion-motive events in plants and in plant model systems. Widmar Tanner summarizes an elegant series of experiments on the proton-coupled hexose transporter in lower and higher plants ( Caspari et al . 1994 ). The phenomenology of symport is discussed elsewhere in this volume ( Kaback et al . 1994...

...Heven Sze; John M. Ward; Shoupeng Lai; Imara Perera ABSTRACT Acidification of endomembrane compartments by the vacuolar-type H + -translocating ATPase (V-ATPase) is vital to the growth and development of plants. The V-ATPase purified from oat roots is a large complex of 650×10 M r that contains 10...
