The plant cell contains a number of well-defined membranes and membrane systems. The plasma membrane forms the barrier between the cytoplasm and the cell exterior, and as such it regulates the exchange of nutrients, acts as the receptor for environmental signals, and helps protect the cell against pathogen attack. This book contains twenty-three chapters by leading researchers on the structure, biogenesis, transport mechanisms, signal transduction, and enzymology of
plant cell membranes, providing insight into new and recent developments in the field.
