Abstract:
The mechanisms of Aluminium tolerance involved during stress condition in some Citrus species. Aluminum (Al) toxicity is one of the major limitations that inhibit plant growth and development in acidic soils. In acidic soils (pH < 5.0), phototoxic-aluminum (Al3+) rapidly inhibits root growth, and subsequently affects water and nutrient uptake in citrus plants. 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. Plants present different degrees of adaptation to aluminium (Al) concentrations in the soil, and the understanding of this characteristic can lead to a viable option for the utilization of acid soils. High temperature and rainfall contribute in turning most of the slope soils acidic in states like Arunachal Pradesh, Assam, Meghalaya, Manipur, Nagaland, Mizoram and Sikkim.

Differential tolerance of plant genotypes to aluminium stress is a more promising approach to increase our understanding of aluminium tolerance in plants. The aluminium cation Al (3+) is toxic to many plants at micromolar concentrations. A range of plant species has evolved mechanisms that enable them to grow on acid soils where toxic concentrations of Al (3+) can limit plant growth. Organic acids play a central role in these aluminium tolerance mechanisms. Some plants detoxify aluminium in the rhizosphere by releasing organic acids that chelate aluminium. Therefore, this review updates the existing knowledge concerning the role of mineral nutrition for alleviating Al toxicity in plants to acid soils.
