چکیده

This chapter will review recent progress in the application of microelectrode techniques to the study of a range of cell physiological problems in plant cells and microorganisms. Plant cells present a special set of problems for electrophysiology and other microelectrode methods, related principally to cell structure (Fig. 1). The past five years have been witness to an great expansion in the application of microelectrode techniques and great progress towards overcoming some of the most significant problems facing plant electrophysiologists, particularly those associated with the presence of the cell wall and intracellular compartmentalization. Consequently, a wide range of plant cell types are now amenable to investigation using modern electrophysiological techniques and this is reflected by the rapidly increasing literature pertaining to plant cell electrophysiology. Virtually all techniques applied to animal cells are now possible with many plant cell types. Here I will outline some of the most significant recent advances in plant cell electrophysiology and discuss problems which remain to be overcome, indicating some of the likely advances in the near future.

Determination of lignin-modifying enzymes (LMEs) in Hyphodermella species using biochemical and molecular techniques

White-rot basidiomycetes are one of the most important lignolytic microorganisms. These fungi have been reported to secrete three main classes of lignin degrading enzymes: lignin peroxidases (LiPs), manganese peroxidases (MnPs) and laccases. In this study, for the first time the lignin degrading capability of two plant pathogens i.e. Hyphodermella rosae and H. corrugata was evaluated using both...

Effect of Indole-3-acetic Acid on Membrane Potentials of Oat Coleoptile Cells.

This paper reports an effect of indole-3-acetic acid on cell membrane potentials. Solutions with increasing IAA concentrations (from 109 to 10-7 M) make membrane potentials of coleop-tile cells more negative. This effect of IAA, which occurs at concentrations that also stimulate tissue elongation, was found inadvertently in the course of an experiment on the effect of IAA on cell wall potential...
