Abstract
Aluminum when in soluble form, as found in acidic soils that comprise about 40 percent of the world's arable land, is toxic to many crops. O rganic acid excretion has been correlated with aluminum tolerance in h igher plants. Overproduction of citrate was shown to result in aluminu m tolerance in transgenic tobacco (Nicotiana tabacum) and papaya (Cari ca papaya) plants.
