With the increasing problem of soil acidification,aluminum(Al)toxicity has become one of the main limiting factors for crop growth and food production in acidic soils of China.Al3+adversely affects plant root physiological functions and morphogenesis by interacting with plant cytoskeleton.At present,plant response to Al toxicity and the mechanism of Al tolerance are still unclear.As a second messenger,calcium(Ca)is an essential mineral element for plant growth,intracellular free Ca2+plays an important role in plant growth,development and stress resistance.The interaction between Ca and Al has attracted the attention of researchers.Relevant studies have confirmed that Ca can alleviate the effects of Al toxicity.This article reviews the recent progress in the research on the interaction between Ca and Al in response to Al toxicity in plants,and briefly discusses the future research directions.
