“…The plant hormones (±)‐jasmonic acid (JA), salicylic acid (SA), (+)‐cis, trans‐abscisic acid (ABA) and 3‐Indoleacetic Acid (IAA) were analyzed by LC‐ESI‐MS/MS in multiple reaction monitoring mode (MRM). These phytohormones were extracted following the methods of Llugany et al ( 2013 ) and Xiao et al ( 2020 ). Briefly, 250 mg of frozen roots and shoots were ground in an ice‐cold mortar and repeatedly extracted with 750 μl Methanol:2‐Propanol:Acetic acid (20:79:1, v/v/v).…”

“…They follow different transport pathways (Raina et al, 2021 ; Zayed et al, 1998 ), which may influence the distribution and accumulation through the plant organs and the Se species formed. Plants can metabolize these inorganic ions into organic Se species, such as selenomethionine (SeMet), selenocysteine (SeCys), selenocystine (SeCyst), methylselenocysteine (MeSeCys), gamma‐glutamyl‐methylselenocysteine, dimethylselenide, dimethyldiselenide and selenocystathionine (Freeman et al, 2006 ; Winkel et al, 2015 ; Xiao et al, 2020 ).…”

“…These drawbacks can be overcome by direct speciation techniques such as X‐ray absorption spectroscopy (XAS) which allows Se speciation in solid form without requiring extraction and pre‐treatment steps. In general, the use of direct speciation techniques and/or combined approaches for Se analysis in plants is scarce (el Mehdawi et al, 2014 ; Freeman et al, 2006 ; Pickering et al, 2000 ), and only a few have studied wheat plants (Wang et al, 2015 ; Xiao et al, 2020 , 2021 ).…”

Thus, a multidisciplinary approach is necessary for unraveling the complete chemical state of Se in plants to comprehend the Se metabolism and ultimately address how Se accumulation in plants should be optimized to improve the specific nutritional value of Se-enriched food (Raina et al, 2021).…”

Wheat can be biofortified with different inorganic selenium (Se) forms, selenite or selenate. The choice of Se source influences the physiological response of the plant and the Se metabolites produced. We looked at selenium uptake, distribution and metabolization in wheat exposed to selenite, selenate and a 1:1 molar mixture of both to determine the impact of each treatment on the Se speciation in roots, shoots, and grains. To achieve a comprehensive quantification of the Se species, the complementarity of high‐performance liquid chromatography coupled with inductively coupled plasma mass spectrometry and X‐ray absorption spectroscopy was exploited. This approach allowed the identification of the six main selenium species: selenomethionine, selenocysteine, selenocystine, selenite, selenate, and elemental selenium. The three treatments resulted in similar total selenium concentration in grains, 90–150 mg Se kg−1, but produced different effects in the plant. Selenite enhanced root accumulation (66% of selenium) and induced the maximum toxicity, whereas selenate favored shoot translocation (46%). With the 1:1 mixture, selenium was distributed along the plant generating lower toxicity. Although all conditions resulted in >92% of organic selenium in the grain, selenate produced mainly C‐Se‐C forms, such as selenomethionine, while selenite (alone or in the mixture) enhanced the production of C‐Se‐Se‐C forms, such as selenocystine, modifying the selenoamino acid composition. These results provide a better understanding of the metabolization of selenium species which is key to minimize plant toxicity and any concomitant effect that may arise due to Se‐biofortification.

“…Because of its diminutive size, Fe nano-oxide can enter plant cells through ion channels or aquaporins by binding to carrier proteins [33]. In the recent past, the foliar application of humic acid (HA), either alone or in combination with other nutrients, has been developed to promote plant growth by increasing photosynthesis, nutrient uptake, hormone activity, and antioxidant scavenging capability [34][35][36][37]. Although the available literature suggests the use of various Fe fertilizers to enhance growth and Fe biofortification, there is still no definite conclusion concerning the forms of Fe compounds suitable for various crop species.…”

Iron (Fe) deficiency in humans, particularly in pregnant women and children, is caused by inadequate dietary Fe intake and is a global nutritional problem. Foliar fertilization is a cost-effective agronomic approach to increase Fe bioavailability in the human diet. We evaluated the effects of different Fe formulations (Fe-citrate, Fe-EDTA, FePO4, nano-Fe oxide, and humic acid (HA) with and without Fe) on growth, yield, and Fe accumulation in the edible parts of rice, soybean, and lettuce crops. Rice and soybean received multiple sprays at different growth stages, i.e., tillering, anthesis, and grain filling in rice as well as flowering and pod filling in soybean, while lettuce received a single foliar spray. In rice and soybean, the seed Fe accumulation increased proportionally as the number of foliar sprays increased; however, the grain yield did not show this relationship. Among Fe treatments, HA+Fe was identified as the best treatment in terms of improving overall plant growth, yield, and Fe accumulation in the edible parts of all three crops. We found a significant positive correlation between the shoot/stover Fe content and the grain Fe content, but HA+Fe showed an opposite trend, i.e., minimal Fe retention in shoots/stovers and maximal increases in the seed Fe contents in both crops, suggesting better Fe mobilization efficiency from shoots to developing seeds. We strongly recommend that HA with Fe can be used as a foliar Fe fertilizer to improve the growth, yield, and Fe status in different crops.
