“…Although the liming of soil can ameliorate some Al and Mn toxicity and increase calcium and magnesium concentrations in many acid soils worldwide, it is expensive and ineffective in the subsoil. In some cases, heavy lime application may cause a deleterious effect on the soil structure and reduce the availability of other cationic micronutrients that are essential for plant growth [17,18]. Plant species vary in their tolerance to stresses in acid soils.…”

Aluminum (Al) and manganese (Mn) toxicity are the top two constraints of crop production in acid soil. Crops have evolved common and specific mechanisms to tolerate the two stresses. In the present study, the responses (toxicity and tolerance) of near-isogenic wheat lines (ET8 and ES8) and their parents (Carazinho and Egret) to Al and Mn were compared by determining the physiological parameters and conducting transcriptome profiling of the roots. The results showed the following: (1) Carazinho and ET8 exhibited dual tolerance to Al and Mn compared to Egret and ES8, indicated by higher relative root elongation and SPAD. (2) After entering the roots, Al was mainly distributed in the roots and fixed in the cell wall, while Mn was mainly distributed in the cell sap and then transported to the leaves. Both Al and Mn stresses decreased the contents of Ca, Mg, and Zn; Mn stress also inhibited the accumulation of Fe, while Al showed an opposite effect. (3) A transcriptomic analysis identified 5581 differentially expressed genes (DEGs) under Al stress and 4165 DEGs under Mn stress. Among these, 2774 DEGs were regulated by both Al and Mn stresses, while 2280 and 1957 DEGs were exclusively regulated by Al stress and Mn stress, respectively. GO and KEGG analyses indicated that cell wall metabolism responds exclusively to Al, while nicotianamine synthesis exclusively responds to Mn. Pathways such as signaling, phenylpropanoid metabolism, and metal ion transport showed commonality and specificity to Al and Mn. Transcription factors (TFs), such as MYB, WRKY, and AP2 families, were also regulated by Al and Mn, and a weighted gene co-expression network analysis (WGCNA) identified PODP7, VATB2, and ABCC3 as the hub genes for Al tolerance and NAS for Mn tolerance. The identified genes and pathways can be used as targets for pyramiding genes and breeding multi-tolerant varieties.

“…By decreasing plant-available Mn 2+ in the soil solution, liming of acid soils and drainage of soils prone to waterlogging are major practices used to overcome poor plant growth due to Mn toxicity (Tisdale and Nelson 1956;Graven et al 1965;Adams 1984;Fageria and Baligar 2008;Moreira et al 2017). Additional ameliorative practices, for which there is less available information, include increased concentrations of Ca, Mg, Si, P, and Fe in the root environment (Foy et al 1978;Horst and Marschner 1978c;Alam et al 2001a;Iwasaki et al 2002b).…”

Frontispiece. Synchrotron-based micro X-ray fluorescence images of manganese (Mn), calcium (Ca), and zinc (Zn) distribution in trifoliate leaves of cowpea and soybean grown in complete nutrient solution with 30 µM Mn and in lower alternate leaves of sunflower and expanded leaves of white lupin at 400 µM Mn. In cowpea and soybean, the small red flecks indicate Mn accumulation in the apoplast, small green spots of Ca accumulation in vacuoles, small green angular spots of Ca oxalate, and the larger red and green areas of Mn and Ca accumulation associated with necrosis. Sunflower trichomes accumulate Mn and Ca. In white lupin, the yellow to orange spots indicate the accumulation of both Mn and Ca in vacuoles. The distance and colour scales apply to all images.
