This book is an overview of our current understanding of aluminium toxicity and tolerance in plants. It covers all relevant aspects from molecular and cellular biology, to genetic approaches, root biology and plant physiology. The contribution of arbuscular mycorrhizal fungi to alleviating aluminium toxicity is also discussed. Over 40% of total agricultural land resources are acidic in nature, with aluminium being the major toxicant. Plant roots are particularly susceptible to aluminium stress, but much of the complex mechanism underlying its toxicity and tolerance is unknown and aluminium stress perception in plants remains poorly understood. The diverse facets of aluminium stress adaptation covered in this book are relevant to plant biology students at all levels, as well researchers and it provides a valuable contribution to our understanding of plant adaptation to the changing environment.
