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. Organic acid excretion has been correlated with aluminum tolerance in higher plants. Overproduction of citrate was shown to result in aluminum tolerance in transgenic tobacco (Nicotiana tabacum) and papaya (Carica papaya) plants.
铝以可溶形式存在时，在占世界可耕地约40%的酸性土壤中被发现，对许多作物有毒。有机酸分泌与高等植物的耐铝性相关。已表明柠檬酸的过量产生会导致转基因烟草（烟草属）和木瓜（番木瓜属）植物具有耐铝性。
