“…Micronutrients are used in several plant physiological processes, and in a relatively small amount, constituting less than 0.1% of dry plant tissue [ 53 ]. The microelement uptake by plants depends both on the content originally present in the soil, as well as from the content that becomes available after plant watering or after plant treatment with chemicals, fertilizers, or biostimulants [ 54 , 55 ]. Plants increase micronutrient uptake in specific conditions, with the aim of increasing the binding of solar energy [ 55 ], improving the conversion of light into chemical energy [ 55 ], intensifying primary or secondary metabolism [ 54 ], or enhancing the enzymatic activity of a large number of enzymes [ 54 ].…”

Plant biostimulants are under investigation as innovative products to improve plant production and fruit quality, without resulting in environmental and food contaminations. Here, the effects of the application of Expando, a biostimulant based on seaweed and yeast extracts, on plant productivity, fruit ripening times, and fruit quality of Solanum lycopersicum var. Micro-Tom were evaluated. After biostimulant treatment, a two-week reduction of ripening times and a concomitant enhancement of the production percentage during the earliest ripening times, in terms of both fruit yield (+110%) and size (+85%), were observed. Concerning fruit quality, proximate analysis showed that tomatoes treated with the biostimulant had better nutritional composition compared to untreated samples, since both the quality of unsatured fatty acids (C16:3ω3: +328%; C18:2ω6: −23%) and micronutrients essential for human health (Fe: +14%; Cu: +21%; Zn: +24%) were increased. From a nutraceutical point of view, despite strong changes in bioactive compound profile not being observed, an increase of the antioxidant properties was recorded in fruits harvested by plants treated with the biostimulant (2,2’-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid (ABTS): +38%; 2,2-diphenyl-1-picrylhydrazyl (DPPH): +11%). In conclusion, the biostimulant application was able to reduce the ripening times and fruit size, while slightly increasing nutritional and nutraceutical values, leading to more marketable tomato fruits.

“…Heat stress occurs when the temperature rises above 75°F. Plant morbidity and mortality increase due to heat stress, and their quality declines (Bhat et al, 2020; dos Santos et al, 2022; Haider et al, 2022; Perrella et al, 2022). Plant cells may undergo permanent changes, like cellular death, if heat stress persists for an extended period.…”

The rhizosphere is the region around the plant roots where maximum microbial activities occur. In the rhizosphere, microorganisms' beneficial and harmful activities affect plant growth and development. The mutualistic rhizospheric bacteria which improve plant growth and health are known as plant growth-promoting rhizobacteria (PGPR). They are very important due to their ability to help the plant in diverse ways.

“…However, Trejo-Tapia et al (2001) highlighted the participation of Co in the synthesis and deposition of secondary metabolites (like sapogenin steroids), as well as betalains. Increased diversity of various secondary metabolites in plants protects against stress (Bhat et al, 2020). The additional significant increases in total phenols and flavonoids in response to treatments of stressed plants of both varieties with Co, support the positive action of Co to venerate the antioxidant properties of these compounds.…”

T HIS STUDY evaluated the impact of cobalt (Co) nutrition at the optimum concentration on growth and oxidative stress in two Egyptian rice varieties (Sakha 104 and Giza 178) under drought stress. The stress was applied at different irrigation intervals (six and eight days), and irrigation after four days was set as control through the reproductive stage. The roots and shoots parameters (lengths, and fresh and dry weights), oxidative stress biomarkers; membrane injury, lipid peroxidation, proline accumulation, protein content, total phenols, and flavonoids contents, along with the activities of catalase (CAT), peroxidase (POX), and polyphenol oxidase (PPO) enzymes, were used to evaluate the strength of reactive oxygen species (ROS) detoxification in both rice varieties. Water deficit and oxidative stress affected Giza 178 less than Sakha 104. Stressed rice plants of both varieties treated with Co at the optimum concentration reduced the hurtful impact of drought, particularly in Giza 178, by enhancing root and shoot growth and biomass and the efficiency of the oxidative defense system. This was obvious in a substantial decrease in membrane injury and lipid peroxidation, while a significant increase was apparent in proline and protein content, total phenols, and total flavonoids. Additionally, the dynamic activities of antioxidant enzymes were substantially higher in Giza 178 than Sakha 104, when compared to untreated plants. The findings could be helpful in research projects aimed at developing anti-drought stress techniques for rice plants.
