“…In soybean roots, Al-tolerance has been shown to result in the release of citrate into the external solution with its high accumulation in the root tip over time (Silva et al 2001;Abdullahi et al 2004). Abscisic acid, protein kinases and up-regulation of plasma membrane H + -ATPase activity are associated with the secretion of citrate from soybean roots (Shen et al , 2005.…”

Nitrogen fixation and assimilation in nodules and roots were studied in soybean (Glycine max L.) exposed to different levels of aluminium (Al) stress (0, 50, 200 and 500 lM). Al at 500 lM induced oxidative stress, which became evident from an increase in lipid peroxidation accompanied by a concomitant decline in antioxidant enzyme activities and leghaemoglobin breakdown. Consequently, there was also a reduction in nitrogenase activity. However, the leghaemoglobin levels and nitrogenase activity were unexpectedly found to be higher in nodules when the plants were treated with 200 lM Al. Of the enzymes involved in nitrogen assimilation, the activity of glutamate dehydrogenase-NADH was reduced in nodules under Al stress, but it was significantly higher in roots at 500 lM Al as compared to that in the control. In nodules, the glutamine synthetase/glutamate synthase-NADH pathway, assayed in terms of activity and expression of both the enzymes, was inhibited at >50 lM Al; but in roots this inhibitory effect was apparent only at 500 lM Al. No significant changes in ammonium and protein contents were recorded in the nodules or roots when the plants were treated with 50 lM Al. However, Al at ‡200 lM significantly increased the ammonium levels and decreased the protein content in the nodules. But these contrasting effects on ammonium and protein contents due to Al stress were observed in the roots only at 500 lM Al. The results suggest that the effect of Al stress on nitrogen assimilation is more conspicuous in nodules than that in the roots of soybean plants.

“…Hasil penelitian ini berbeda dari Abdullahi et al (2006) pada kecambah kedelai. Pada 2 mM Al asam sitrat mengurangi cekaman aluminium dengan meningkatkan berat segar sampai 8 % tapi tidak memiliki efek terhadap berat kering.…”

“…Asam sitrat merupakan asam organik lemah yang mempunyai rumus kimia C 6 H 8 O 7 (Sarulli dan Damayanti, 2010). Menurut Abdullahi et al (2006) asam sitrat 5 mM tidak berpengaruh terhadap pertumbuhan kecambah kedelai dalam ketiadaan aluminium. Pada Al 2 mM dan 5 mM nampaknya asam sitrat hanya memperbaiki toksisitas aluminium, mengakibatkan pertumbuhan kecambah kedelai dengan meningkatkan panjang hipokotil, panjang kecambah dan panjang akar kecambah.…”

“…CA is an intermediate of the Krebs cycle, and known to serve as a carbon source for various metabolic reactions and increase activities of antioxidant enzymes (Trejo‐Tellez et al 2012). CA also protects plants from deleterious effects of various environmental stresses, including heat stress (Hu et al 2016) and aluminium stress (Abdullahi et al 2004). Moreover, ASC application increased growth parameters, decreased ROS accumulation and upregulated antioxidant enzymes under several abiotic stresses (Elhamid et al 2014; Dawood et al 2017).…”

Copper (Cu) pollution of agricultural land is a major threat to crop production.Exogenous chemical treatment is an easily accessible and rapid approach to remediate metal toxicity, including Cu toxicity in plants.• We compared the effects of ascobin (ASC; ascorbic acid:citric acid at 2:1) and glutathione (GSH) in mitigation of Cu toxicity in rice.• Plants subjected to Cu stress displayed growth inhibition and biomass reduction, which were connected to reduced levels of chlorophylls, RWC, total phenolic compounds, carotenoids and Mg 2+ . Increased accumulation of ROS and malondialdehyde indicated oxidative stress in Cu-stressed plants. However, application of ASC or GSH minimized the inhibitory effects of Cu stress on rice plants by restricting Cu 2+ uptake and improving mineral balance, chlorophyll content and RWC. Both ASC and GSH pretreatments reduced levels of ROS and malondialdehyde and improved activities of antioxidant enzymes, suggesting their roles in alleviating oxidative damage. A comparison on the effects of ASC and GSH under Cu stress revealed that ASC was more effective in restricting Cu 2+ accumulation (69.5% by ASC and 57.1% by GSH), Ca 2+ and Mg 2+ homeostasis, protection of photosynthetic pigments and activation of antioxidant defence mechanisms [catalase (110.4%), ascorbate peroxidase (76.5%) and guaiacol peroxidase (39.0%) by ASC, and catalase (58.9%) and ascorbate peroxidase (59.9%) by GSH] in rice than GSH, eventually resulting in better protection of ASCpretreated plants against Cu stress. • In conclusion, although ASC and GSH differed in induction of stress protective mechanisms, both were effective in improving rice performance in response to Cu phytotoxicity.
