Plants are most affected by the abiotic (temperature, drought, salinity etc.) and biotic stresses (bacteria, fungus, virus, nematode etc.) which have been increased by the disturbances posed by human intervention, climate change, improper use of pesticides and environmental cues. Plants are sessile in nature and they require unprecedented advances to protect themselves from the harsh environment like other living organisms. There are several studies indicating that the plants have evolved themselves over time to utilise beneficial elements to enhance their development, photosynthetic capacity, antioxidant enzyme activity and finally they can stimulate mechanisms of resistance to abiotic and biotic stress factors. Essential elements, certain elements known as beneficial elements support the growth and development of plants as well as improving responses to stressors and environmental stimuli. When plants are exposed to environmental cues such as saline soils, heavy metal toxicity, drought, low temperatures, pathogens or pest insects, beneficial elements may induce defence response, tolerance and resistance that allows plants to survive against such stressors. Hence, beneficial elements may have promising potential to cope with climate change and plant productivity under restrictive conditions. This review discusses about the mechanism, uptake and current research demonstrating the importance and significance of beneficial elements such as Silicon, Selenium, Titanium, Iodine and Cadmium metals.
