“…However, a significant reduction in SOD and GR activities due to TIBA under Zn deficiency indicated crosslink between auxin signaling and elevated antioxidant activities in roots of Pokkali. To withstand abiotic stresses, plants adapt antioxidant defense for restoring redox metabolism and cellular turgor (Subba et al 2014;Kabir et al 2015). Our results also indicated that auxin might be helpful for keeping SOD balance in plants.…”

This study elucidates the involvement of auxin with Zn-efficiency (ZE) in Zn-efficient rice var. Pokkali. Pokkali showed no significant decrease in morpho-physiological features, electrolyte leakage and total soluble proteins due to Zn deficiency as compared with Zn-sufficient seedlings. However, auxin inhibitor under Zn deficiency severely affected these characteristics, suggesting that ZE is associated with auxin signaling in rice. Results further revealed significant decreases in the expression of Zn transporter genes (OsIRT1, OsZIP4 and OsZIP1), OsDMAS1 (deoxymugeneic acid synthase) and phytochelatin in roots due to auxin inhibitor. It implies that auxin signaling may trigger Zn uptake, transport and chelation in rice seedlings to withstand Zn-deficiency. Further, significant reduction of major S-metabolites (cysteine, methionine, glutathione) and antioxidant enzymes (superoxide dismutase and glutathione reductase) along with increased H 2 O 2 content, due to auxin inhibitor under Zn deficiency compared with controls. Taken together, these findings reveal that mechanisms associated with ZE in Pokkali are dependent on auxin signaling. ARTICLE HISTORY

“…The concentrations of heavy metals in the MSWVC amended soils were found in the order of Fe > Zn > Cu > Cr > Ni > Pb > Cd. Zn is an important micronutrient for different metabolic functions in plants; however, it's toxic levels in soil lead to reduced plant growth, leaf chlorosis, photosynthesis impairment, and reactive oxygen species (ROS) production that poses harm to membrane integrity and permeability (Cambrollé et al 2012, Subba et al 2014, Srivastava et al 2017. Moreover, high concentrations of Zn adversely affect dehydrogenase, β-D-glucosidase, urease, catalase, and invertase activities in soil (Kunito et al 2001, Yang et al 2006, Ciarkowska et al 2014.…”

Purpose In the present study, effect of earthworm-processed MSW was seen on biochemical, physiological, and yield responses of Abelmoschus esculentus L. Methods Plants were grown on different amendment ratios of municipal solid waste vermicompost (MSWVC). Pot experiments were conducted by mixing MSWVC at 0, 20, 40, 60, 80, and 100% ratios to the agricultural soil. Results An increase in photosynthetic rate and stomatal conductance of plants grown at 20 and 40% MSWVC amendment ratios was observed. Total chlorophyll, carotenoid, and protein contents also increased significantly in 20, 40, and 60% amendment ratios at 65 days after germination (DAG). Likewise, proline, peroxidase, and lipid peroxidation increased with increasing levels of MSWVC at both 45 and 65 DAG. Conclusion The study suggests that MSWVC could be used as organic amendment in soil depicted by good yield and antioxidative response of lady's finger (A. esculentus) at different amendments of MSWVC (up to 60% w/w ratios). Furthermore, agricultural utilization of MSWVC will help in managing dreadful effects of the burgeoning amount of organic solid waste.

“…Other non-enzymatic metabolites like MDA, proline and ascorbic acid also reversed their accumulation behavior in Zn supplemented Zn-Cd combination treatment compared to Cd only treatments. Addition of Zn to Cd stressed plants helps in lowering MDA content and proline accumulations (Khalid and Hendawy, 2005;Subba et al, 2014;Qiao et al 2015). Zn supplementation lowers the abiotic stress including that of heavy metal Cd by raising ascorbic acid levels (Ozturk et al, 2003Seminario et al, 2017).…”

The interaction between cadmium- a toxic metal and zinc- an essential micronutrient was investigated in influencing the activity of various antioxidant enzymes and related metabolites in soybean [Glycine max (L.) Merr.]. Higher levels of cadmium (Cd) stimulate the activity of potential enzymes like ascorbate peroxidase (APX), superoxide dismutase (SOD) accompanied by the buildup of non-enzymatic metabolites, hydrogen peroxide (H2O2), malondialdehyde (MDA) and proline due to rise in oxidative stress of plants. Also, the reduced activity of catalase (CAT), glutathione reductase (GR) and ascorbic acid (AsA) content was based upon Cd treatment levels. Application of zinc (Zn) combination enhances the activity of enzymes like APX, GR, CAT and SOD in Cd treatments, also confirmed with the depleted levels of H2O2. Zn alone treatment had no significant effect on the activity of such enzymes indicating the toxicity owing to Cd treatments only. The accumulation behavior of other non-enzymatic metabolites like MDA, proline and ascorbic acid also get reversed with metal combination treatment. Moreover, the efficacy of Zn was more when applied in higher concentrations with low Cd. Thus, Zn plays a key role in plants to counter heavy metal stress by elevating antioxidative defense with higher activity of enzymes and reduced levels of non-enzymatic metabolites, and efficacy of Zn in combination is dose dependent.
