Abstract: Acidification is identified in 30%-40% arable land worldwide. Furthermore, the soil acidity is gradually serious. Aluminum (Al) toxicity is a major limiting factor for plant growth and crop production in acid soils. The tea plant (Camellia sinensis (L.) O. Kuntze) exhibits good performance when exposed to a proper Al level, and accumulates high Al in the leaves without representative toxicity symptoms, such as growth inhibition of root tip, falling of the epidermis of root cap. Thus, tea plant is considered as an Al hyper accumulator. This review summarized the progress of Al accumulation, forms, subcellular location or distribution and its physiological responses of tea plant to Al. Additionally, the potential mechanisms and future researches related to Al tolerance or accumulation in tea plant were also discussed.

Key words: tea plant, aluminum, organic acid, transporter, transcription factor
