Part of the Modern Methods of Plant Analysis book series (MOLMETHPLANT, volume 11) Abstract The use of electricity in plant physiology is natural from the biophysical point of view, since many substances transported in the plant are charged, and since electrical signals have properties suitable for both transfer and transduction of by: 1. Proteomic analyses of C. australis vacuole and cytoplasm, including membrane proteins such as transporter molecules, complement the metabolomic data presented in this study. Internodal cells of species belonging to family Characeae have been used frequently for studying membrane physiology such as a cellular potential (Tazawa et al., ).Cited by:

Electrophysiology has proven to be a powerful tool in understanding animal physiology and development, yet it has been virtually neglected in the study of plant physiology and by:

  The second class of solutions of the Ortega equation (Fig. 2, C and D) would represent growth and pressure change over time for different plant species or tissues. Also, it is likely to represent the character of GR(t) and P (t) changes in various environmental conditions (e.g. temperature, pH, water and soil factors, light, etc.).

Certain inhibitors have been found to affect the low frequency spectral component of the electrical noise power spectrum in Chara corallina.

Application of the ATPase inhibitor N,N′ -dicyclohexylcarbodiimide removed the low frequency spectral component, strengthening the case that the component is produced by active proton by: 1. pH banding and accumulation of lipophilic dyes in plasma membrane domains of Chara corallina internodal cells.

A sinusoidal AC current (usually at 1 Hz) was injected into either the acid or basic zone present in illuminated internodal cells ofChara.

The “cable” properties of the cell were then studied by two techniques. The first involved measuring the dependence of the transverse AC membrane current (measured in the external medium) upon the distance away from the point of current by:   The identity of the plasmalemma-transported species that develops the alkaline bands of Chara corallina was investigated.

Quantitative information on the uptake and distribution of Al at the cellular level is required to understand mechanisms of Al toxicity, but direct measurement of uptake across the plasma membrane has remained elusive.

In this sense, the species Chara corallina is the plant equivalent to the squid axon in the study of ion transport in plants. The recent phylogenetic analysis of the Characeae has again strengthened the model character of Chara.
