“…There are few reports of proline synthesis under Fe-deficiency. Heidari and Sarani (2012) reported that Fe-deficient chamomile plants accumulated higher amounts of proline under salinity than Fe-sufficient plants, the same as found for Belgrano in this study. On the other hand, there is only one report showing proline accumulation in Fe-deficient plants, an early study in rice (Alia and Saradhi, 1993).…”

“…The same observations can be reported for the roots of M. maritima that maintained their vigor at 100 mM and 200 mM NaCl. Heidari and Sarani (2012) found that increasing salinity from 0 to 150 mM decreased FW of shoots and increased that of roots in M. chamomilla.…”

In the present study, we compared the response to salinity of three plants from Brittany coast with contrasted ecological status: Limonium latifolium (salt marshes), Matricaria maritima (beach tops and sand dunes) and Crambe maritima (fixed dunes). Under controlled glasshouse conditions, the growth of the three plants decreased with increasing external salinity. L. latifolium and C. maritima exhibited the highest and lowest resistance to severe salt stress (400 mM), respectively. M. maritima could be considered as an intermediate species, since it tolerated salinity up to 200 mM. The same observation could be made with sodium absorption and acuumulation in plant tissues, the most tolerant species (L. latifolium being the least Na accumulator. Hydrogen peroxide (H2O2) and malondialdehyde (MDA), commonly produced in conditions of stress, accumulated significantly in salt treated C. maritima and M. maritima while not in the tolerant L. latifolium. The latter used glutathione reductase to maintain constant H2O2 levels under salt stress while peroxidases were very low and ascorbate peroxidase did not respond to salinity stimulation. The medium tolerant halophyte M. maritima used peroxidases to protect from NaCl-induced H2O2, while the sensitive C. maritima failed to detoxify H2O2 despite a sharp increase in catalase activity. Results showed that the three coastal species differ in resistance to salinity. They also suggested that the level of plant resistance to salinity could be attributed to differing mechanisms to manage the accumulation of sodium and cope with the oxidative damages.

“…Hassan et al (1970), Dahiya and Singh (1976) and Okcu et al (2005) showed the adverse effect of salinity on the accumulation of Fe content in the shoots of barley, corn, and pea. Furthermore, Heidari and Sarani (2012) reported adverse effects of salinity in the chamomile plant, including stunted growth and a reduction in biochemical components and ion content. Yousfi et al (2007) have also reported deleterious effect of salt on the physiological processes of barley due to the disturbance in Fe acquisition in plants caused by reducing the flow of phytosiderophore.…”

Iron (Fe) is a micronutrient that plays an important role in agriculture worldwide because plants require a small amount of iron for its growth and development. All major functions in a plant's life from chlorophyll biosynthesis to energy transfer are performed by Fe (Brumbarova et al., 2008;Gill and Tuteja, 2011). Iron also acts as a major constituent of many plant proteins and enzymes. The acquisition of Fe in plants occurs through two strategies, i.e., strategy I and strategy II (Marschner and Römheld, 1994). Under various stress conditions, Nramp and the YSL gene families help in translocation of Fe, which further acts as a mineral regulatory element and defends plants against stresses. Iron plays an irreplaceable role in alleviating stress imposed by salinity, drought, and heavy metal stress. This is because it activates plant enzymatic antioxidants like catalase (CAT), peroxidase, and an isoform of superoxide dismutase (SOD) that act as a scavenger of reactive oxygen species (ROS) (Hellin et al., 1995). In addition to this, their deficiency as well as their excess amount can disturb the homeostasis of a plant's cell and result in declining of photosynthetic rate, respiration, and increased accumulation of Na + and Ca − ions which culminate in an excessive formation of ROS. The short-range order hydrated Fe oxides and organic functional groups show affinities for metal ions. Iron plaque biofilm matrices could sequester a large amount of metals at the soil-root interface. Hence, it has attracted the attention of plant physiologists and agricultural scientists who are discovering more exciting and hidden applications of Fe and its potential in the development of bio-factories. This review looks into the recent progress made in putting forward the role of Fe in plant growth, development, and acclimation under major abiotic stresses, i.e., salinity, drought, and heavy metals.
