Abstract: In this paper the current advances in studies on aluminum stress in plants are reviewed. Al3+ may adversely influence the function and morphogenesis of plant roots by acting on cytoskeleton and is harmful to many plant species. The plants may become tolerant to Al3+ through secretion of organic acids or phosphate to bind with Al3+, by taking up H+ to alkalize the rhizosphere to reduce the apoplastic Al3+ activity, or by formation of nonphytotoxic complexes to reduce the symplastic Al3+ activity. Genetic engineering and mutant selection have been employed in breeding for Al3+ tolerance in plants. Tolerance to Al3+ in plants may be controlled by a single gene or multigenes.
