“…One of the major consequences of metal/metalloid stress is nutrient deficiency, as metal/metalloids compete with essential mineral elements for uptake into the plant [43]. Nutrient homeostasis could therefore reduce metal/metalloid accumulation, and thereby their toxicity, to enhance many physiological mechanisms under Cd stress conditions.…”

Cadmium (Cd) is a toxic heavy metal that enters the human food chain from the soil via plants. Increased Cd uptake and translocation in plants alters metabolism andreduces crop production. Maintaining crop yield therefore requires both soil remediation andenhanced plant tolerance to Cd. In this study, we investigated the effects of vanillic acid (VA) on Cd accumulation and Cd stress tolerance in rice (Oryza sativa L. cv. BRRI dhan54). Thirteen-day-old rice seedlings treated with CdCl2 (1.0 and 2.0 mM) for 72 h showed reduced growth, biomass accumulation, and water and photosynthetic pigment contents, as well as increased signs of oxidative stress (elevated levels of malondialdehyde, hydrogen peroxide, methylglyoxal, and lipoxygenase) and downregulated antioxidant and glyoxalase systems. Cadmium-induced changes in leaf relative turgidity, photosynthetic pigment content, ascorbate pool size, and glutathione content were suppressed by VA under both mild and severe Cd toxicity stress. The supplementation of VA under Cd stress conditions also increased antioxidant and glyoxylase enzyme activity. Vanillic acid also increased phytochelatin content and the biological accumulation factor, biological accumulation co-efficient, and Cd translocation factor. Vanillic acid, therefore appears to enhance Cd stress tolerance by increasing metal chelation and sequestration, by upregulating antioxidant defense and glyoxalase systems, and by facilitating nutrient homeostasis.

“…Such detoxification prevents cell injury and tissue dysfunction. This reduction in phenolic compounds might also be attributed to the role of their hydroxyl and carboxyl group in the scavenging of free radicals and chelating heavy metals (Yadav et al, 2016) or due to the utilization of simple phenols in the formation of complex compounds like flavonoids, tannins, and lignins (Mondal et al, 2015).…”

Fava bean, Vicia faba L, is one of the oldest crops grown and used as a protein source for humans and animals (Bishnoi et al., 2012). This crop fixes atmospheric nitrogen in a symbiotic relationship with rhizobium bacteria in the soil (Karla, 2009). It plays a significant dietary role in supplying proteins, carbohydrates, essential elements, and vitamins to rural and urban people. The fresh pods and green seeds are eaten boiled or are used to prepared curries; ripe seeds are used as pulse, often as soup "dhal" (Sultana, 2001). Viral diseases have a significant status because they cause direct damage to the host and predispose the plant to secondary invaders (Mahgoub et al., 1997). Bean yellow mosaic virus (BYMV) is the most common and prevalent virus among fava bean viruses (Sofy et al., 2019). 89% of the Egyptian fava bean fields surveyed with high-level BYMV symptoms (80-100% infection) (Makouk et al., 2003). To control ROS and protect the cells, plants possess several low molecular weight antioxidants (ascorbate, phenolic compounds, tocopherols) and enzymes (SOD, CAT, APX), scavenging ROS and regenerating the active forms of antioxidants. Under normal conditions, ROS production and scavenging are well regulated. In this way, this enzyme system can

“…Among the remedies for abiotic stress, nutrient regulations or management are considered as the cost effective and eco-friendly techniques Yadav et al, 2016). It has been reported that plant nutrients (micro and macro) play important roles in growth and development (White and Brown, 2010;Waraich et al, 2011;Tripathi et al, 2014Tripathi et al, , 2015.…”

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.
