“…However, soaking grains + foliar spraying two times with 0.05 mM t Zck and/or 0.5 mM Sm stimulated minimization of Cd toxicity in plants, improving growth and yield, leaf photosynthetic pigments, and leaf photosynthetic efficiency, reducing oxidative stress biomarkers and Cd contents (in roots, leaves and yielded grains), and positively modifying all antioxidative (i.e., enzymatic and non-enzymatic) defense machineries. These results concur with those of Alharby et al [ 4 ], Alharby et al [ 42 ], Azzam et al [ 43 ], Salman et al [ 47 ], and Desoky et al [ 71 ], who reported that treating plants with Sim or t Zck as grain soaking or foliar application regulated the plant’s adaptive responses via physio-biochemical, metabolic and molecular modulation under different abiotic and biotic stresses, including Cd stress.…”

“…It has been utilized to cure liver diseases [ 46 ]. More recently, it has been used alone or as an additive to enrich plant biostimulants to attenuate the adverse impacts of stress [ 4 , 47 ], being a secondary metabolite; a bioactive antioxidant. Its extract is comprised of six chemical bioactive flavonoids and flavonolignans; isosilychristins, isosilybins (A and B), silybinins or silibinins (A and B), silychristins, silydianins, and flavonoids (e.g., taxifolin) [ 48 ].…”

Pot trials were performed to explore the impacts of seed priming (SPr) plus leaf treatment (LTr) with trans-zeatin-type cytokinin (tZck; 0.05 mM) and silymarin (Sim; 0.5 mM) on growth, yield, physio-biochemical responses, and antioxidant defense systems in Cd-stressed wheat. tZck + Sim applied as SPr + LTr was more effective than individual treatments, and the impacts were more pronounced under stress conditions. Cd stress (0.6 mM) severely declined growth and yield traits, and photosynthesis efficiency (pigment contents, instantaneous carboxylation efficiency, and photochemical activity) compared to the control. These negative impacts coincided with increased levels of Cd2+, O2•‒ (superoxide), H2O2 (hydrogen peroxide), MDA (malondialdehyde), and EL (electrolyte leakage). Non-enzymatic and enzymatic antioxidant activities, and tZck and Sim contents were also increased. However, tZck + Sim increased photosynthesis efficiency, and further boosted antioxidant activities, and contents of tZck and Sim, while minimizing Cd2+ levels in roots, leaves, and grains. The levels of O2•‒, H2O2, MDA, and EL were also minimized, reflecting positively on growth and productivity. tZck + Sim applied as SPr + LTr was highly effective in promoting antioxidants and photosynthesis machineries, minimizing oxidative stress biomarkers and Cd2+ levels, boosting tolerance to Cd stress, and improving wheat productivity under Cd stress.

“…The potential for high yields and the diverse chemical composition of milk thistle fruits and vegetative biomass have opened the door to a wide range of potential applications of silymarin (Table 1). These applications span from livestock nutrition to human dietary use and industrial applications, encompassing various plant components, derivatives, and extracts [14][15][16]19,20,46,47]. Drought stress enhanced the accumulation of silymarin in milk thistle seeds and improved its quality by increasing the share of silybin, which possess the greatest degree of biological activity among the silymarin components.…”
