“…Our study showed that both the malate and citrate contents in 1.2 mM Al-treated sour pummelo leaves increased with decreasing P supply, but the contents in 0 mM Al-treated leaves did not change in response to P (Chen et al 2009). Watanabe and Osaki (2002) reported that Al increased the contents of citrate, oxalate and malate in Melastoma malabathricum leaves.…”

“…Recently, our study showed that Al decreased the contents of malate and citrate in Citrus grandis roots in the presence of 50 μM phosphorus, but did not affect the activities of CS, aconitase (ACO, EC 4.2.1.3), phosphoenolpyruvate carboxylase (PEPC, EC 4.1.1.31), NADP-isocitrate dehydrogenase (NADP-IDH, EC 1.1.1.42), NAD-malate dehydrogenase (NAD-MDH, EC 1.1.1.37) and NADPmalic enzyme (NADP-ME, EC 1.1.1.40). In contrast, Al decreased the activities of CS, ACO, PEPC and NADP-IDH in the roots at 500 μM P, but did not affect the contents of malate and citrate (Chen et al 2009).…”

“…Our study with sour pummelo seedlings showed that P could alleviate the Al-induced inhibition of growth and photosynthesis by increasing Al immobilization in roots and decreasing Al level in shoots (leaves). Both the contents of malate and citrate and the activities of acidmetabolizing enzymes were less affected by P-Al interactions in the roots than in the leaves, which might be attributed to the smaller changes in the root Al than in the leaf Al (Chen et al 2009). OA metabolism can be less affected by B-Al interactions in the roots than in the leaves, as it exerted less effect on the Al level in the roots than in the leaves (Jiang et al 2009a,b).…”

Sour pummelo (Citrus grandis) seedlings were irrigated with nutrient solution containing four boron concentrations (i.e., 2.5, 10, 25 and 50 μM H 3 BO 3 ) and two aluminum concentrations [i.e., 0 (-Al) and 1.2 mM AlCl 3 . 6 H 2 O (+Al)]. It was found that B did not affect, but Al increased, the Al content in the roots. The Al and citrate contents in the -Al leaves either did not change or slightly increased with increasing B concentration. On the other hand, the Al and citrate contents in the +Al leaves rapidly decreased as B concentration increased from 2.5 to 50 μM, then decreased at the highest B concentration. The Al and citrate contents were higher in the +Al than in the -Al leaves, except for at 25 μM B when they were similar. The leaf malate content did not change in response to B or Al, except for an increase in the +Al leaves and a decrease in the -Al leaves at 2.5 μM B. Similarly, the root malate and citrate contents did not change in response to B with or without Al, except for a decrease in the malate and citrate contents in the +Al roots at 50 μM B and an increase in the citrate content in the -Al roots at 50 μM B. The activities of acid-metabolizing enzymes were less affected by B-Al interactions in the roots than in the leaves.Additional key words: acid-metabolizing enzymes, citrate, malate, sour pummelo.

“…Furthermore, the higher Al-tolerance observed in C. sinensis may be due to secretion of organic acids and precipitation of Al by P in roots. Chen et al (2009) also observed Al-induced secretion of malate and citrate in C. grandis. They reported that concentrations of malate and citrate were less affected by the interaction of P and Al in roots compared to leaves.…”

World Agriculture faces daunting challenges in feeding the growing population today. Reduction in arable land extent due to numerous reasons threatens achievement of food and nutritional security. Under this back ground, agricultural use of acidic soils, which account for approximately 40 % of the world arable lands is of utmost important. However, due to aluminum (Al) toxicity and low available phosphorous (P) content, crop production in acidic soils is restricted. Citrus, in this context, gains worldwide recognition as a crop adapted to harsh environments. The present paper reviewed Al toxicity and possible toxicity alleviation tactics in citrus. As reported for many other crops, inhibition of root elongation, photosynthesis and growth is experienced in citrus also due to Al toxicity. Focusing at toxicity alleviation, interaction between boron (B) and Al as well as phosphorus and Al has been discussed intensively. Al toxicity in citrus could be alleviated by P through increasing immobilization of Al in roots and P level in shoots rather than through increasing organic acid secretion, which has been widely reported in other crops. Boron-induced changes in Al speciation and/or sub-cellular compartmentation has also been suggested in amelioration of root inhibition in citrus. Despite the species-dependent manner of response to Al toxicity, many commercially important citrus species can be grown successfully in acidic soils, provided toxicity alleviation Agro-biological tactics such as addition of phosphorous fertilizers are used properly.

Al treatment decreased leaf, stem, and root fresh and dry weight of "Cleopatra" tangerine ( Citrus reshni Hort. ex Tan.) seedlings, but increased leaf dry weight per area. Leaf and stem fresh and dry weight decreased to a greater degree than root fresh and dry weight in response to Al and resulted in a Abstract Aluminum (Al) toxicity is the major factor limiting plant growth in acidic soils, which comprise up to 50% of the world's potentially arable lands. Citrus belong to evergreen subtropical fruit trees and are cultivated in humid and subhumid of tropical, subtropical, and temperate regions of the world mainly on acidic soils. Soil acidi fi cation is a major problem in citrus plantations. There has been signi fi cant progress in our understanding of the physiological responses and the tolerance of citrus to Al toxicity during the past decade. In this chapter, growth, physiological responses (carbohydrates, photosynthesis, water relation, light energy utilization, photoprotective system, mineral nutrients, and organic acids), and tolerance (genotypic differences, Al uptake, and distribution, and Al-induced secretion of organic acid anions) of citrus to Al toxicity are reviewed. The amelioration of phosphorus (P) and boron (B) on citrus Al toxicity as well as some aspects needed to be further studied are also discussed.
