In mangrove forests, iron (Fe) performs several vital roles as it is an essential nutrient for plants (Alongi 2010) and marine plankton (Quéguiner 2013), and controls the cycle of crucial elements, including carbon (C), phosphorus (P), trace metals, and sulfur (S) (Sherman et al. 1998).For example, in the soil of mangrove forests as …

Role of plant growth regulator in iron toxicity tolerance. Since Fe is an essential micronutrient playing a critical role as an electron donor or an acceptor in both photosynthesis and respiration, it becomes a contaminant only at higher concentrations in the soil (Conte and Walker, 2011). Plants, therefore, respond to elevated Fe in several …
