ABOUT THE BOOK
Though plant cells are separated by cell walls, cells maintain their identity
as they are delimited by semi-permeable membranes that permit them to function
as autonomous units. The flow of materials in and out of the cell is regulated
by channels, transporters, pumps, and acquaporins in these membranes. The cytoplasm
is sandwiched between two membranes: the plasma membrane, which forms the outer
boundary of the cytoplasm, and the tonoplast or the vacuolar membrane which
forms the inner boundary. Cell membranes serve several different functions:
form boundaries and provide compartmentalization, site of chemical reactions
catalyzed by membrane proteins, regulate the exchange of ions/compounds across
the barrier, site of perception/transmission of signals (hormones), and act
in cell-to-cell communication. The membrane functions are affected by different
abiotic (biotic stress not discussed), nutritional, edaphic and mechanical stresses,
which have been discussed in this volume in light of the recent literature/researches.
This book will be useful to advanced students, teachers and researchers interested
in crop stress physiology, especially in understanding, planning and execution
of further research.
