“…Small Al concentrations (micromolar) can inhibit root elongation in minutes or hours, inhibiting the water and nutrient uptake, resulting in reduced growth and yield (MA & FURUKAWA, 2003;RAHMAN et al, 2018). Since roots are strongly affected by Al, many reports have shown the evaluation of traits related to the growth of the root system (CHANG et al, 2015). Here, to understand the Al toxicity effects on rice Brazilian genotypes, we evaluated the root length trait in BR-IRGA 410, BRS Curinga, IAS 12-9 Formosa and Farroupilha genotypes in response to 14mg L -1 of Al during 96 hours (Figure 1).…”

“…In acid soils, Al is solubilized to its ionic form (Al 3+ ), which is toxic to the plants (FOY, 1988;ARENHART et al, 2014). The presence of Al in soil solution quickly inhibits the root growth as well as water and nutrient uptake by the plant, resulting in a significant reduction in the crop production under these conditions (CHANG et al, 2015). It is estimated that acidic soils comprise 40 and 50% of the world's arable soil (KOCHIAN et al, 2015;RAHMAN et al, 2018).…”

In soils under acidic conditions, Aluminum (Al) is solubilized to its ionic form, which is toxic to plants. Al rapidly inhibits root elongation, water and nutrient uptake, resulting in crop yield reduction. Members of the MATE family are responsible for citrate transport and Al detoxification in different species. In rice, the OsFRDL1 gene (MATE family) is homologous to the HvAACT1 and SbMATE, which are involved in Al tolerance in barley and sorghum, respectively. Silencing OsFRDL1 showed that it is not involved in Al tolerance in rice. However, the OsFRDL1 expression was not accessed in rice genotypes contrasting for Al tolerance. Thus, in this study, four Brazilian rice genotypes were evaluated in response to Al treatment in different time of exposition and OsFRDL1 expression was analyzed. The analyzed cultivars displayed different responses to Al dose x time. Al affected root growth in all analyzed genotypes, however, a minor negative effect that only occurred after 72 and 48 hours of exposure was detected in Farroupilha and BRS Curinga cultivars, respectively. In contrast, BR-IRGA 410 and IAS 12-9 showed a negative effect in root growth from the first hours of exposure to Al. Two cultivars differing in Al tolerance were used for gene expression analysis. The expression of OsFRDL1 was highly increased in Al-tolerant cultivar Farroupilha than in the Al-sensitive cultivar BR IRGA 410. This results indicates that OsFRDL1 is regulated by Al. This finding suggests that OsFRDL1 is involved in Al stress response, however seems to be insufficient in controlling Al tolerance.

“…Moreover, the genotype difference in shoot production suggested that screening cultivars could offer options to boost production while enhancing co-benefits in rice agriculture (Noguera et al, 2011 ). The two Japonica rice cultivars of W7 and NP were widely used as mother plant in rice breeding and as a model plant in rice research in China and Asian countries (Gao et al, 2011 ; Chang et al, 2015 ), and cultivar innovation by germplasm had been mostly with yield improvement by <15% (Peng et al, 2008 ). Thus, there could be a great potential to use a sound combination of optimal crop cultivar with biochar application in crop production improvement.…”

While biochar use in agriculture is widely advocated, how the effect of biochar on plant growth varies with biochar forms and crop genotypes is poorly addressed. The role of dissolvable organic matter (DOM) in plant growth has been increasingly addressed for crop production with biochar. In this study, a hydroponic culture of rice seedling growth of two cultivars was treated with bulk mass (DOM-containing), water extract (DOM only), and extracted residue (DOM-free) of maize residue biochar, at a volumetric dosage of 0.01, 0.05, and 0.1%, respectively. On seedling root growth of the two cultivars, bulk biochar exerted a generally negative effect, while the biochar extract had a consistently positive effect across the application dosages. Differently, the extracted biochar showed a contrasting effect between genotypes. In another hydroponic culture with Wuyunjing 7 treated with biochar extract at sequential dosages, seedling growth was promoted by 95% at 0.01% dosage but by 26% at 0.1% dosage, explained with the great promotion of secondary roots rather than of primary roots. Such effects were likely explained by low molecular weight organic acids and nanoparticles contained in the biochar DOM. This study highlights the importance of biochar DOM and crop genotype when evaluating the effect of biochar on plants. The use of low dosage of biochar DOM could help farmers to adopt biochar technology as a solution for agricultural sustainability.

“…Soluble Al ions, especially Al +3 , are released at the soil exchange complex in soils with pH values lower than 5. These ions lead to root growth inhibition, resulting in decreased water and nutrient uptake and plant growth and changes in dry matter partitioning between the root and shoot (Chang et al, 2015;Eekhout et al, 2017). For this reason, Al is considered one of the primary abiotic factors that limit agricultural productivity (Ritchey et al, 1995;Ryan et al, 2011).…”

Aluminium (Al) is a toxic element for plants living in soils with acidic pH values, and it causes reductions in the roots and shoots development. High Al concentrations can cause physiological and structural changes, leading to symptoms of toxicity in plant tissue. The aim of this study was to describe the Al toxicity in soybean plants through physiological, nutritional, and ultrastructure analyses. Plants were grown in nutrient solution containing increasing Al concentrations (0; 0.05; 0.1; 1.0, 2.0 and 4.0 mmol L). The Al toxicity in the soybean plants was characterized by nutritional, anatomical, physiological, and biochemical analyses. The carbon dioxide assimilation rates and stomatal conductance were not affected by the Al. However, the capacity for internal carbon use decreased, and the transpiration rate increased, resulting in increased root biomass at the lowest Al concentration in the nutrient solution. The soybean plants exposed to the highest Al concentration exhibited lower root and shoot biomass. The nitrate reductase and urease activities decreased with the increasing Al concentration, indicating that nitrogen metabolism was halted. The superoxide dismutase and peroxidase activities increased with the increasing Al availability in the nutrient solution, and they were higher in the roots, showing their role in Al detoxification. Despite presenting external lesions characterized by a damaged root cap, the root xylem and phloem diameters were not affected by the Al. However, the leaf xylem diameter showed ultrastructural alterations under higher Al concentrations in nutrient solution. These results have contributed to our understanding of several physiological, biochemical and histological mechanisms of Al toxicity in soybean plants.
