“…It was reported that when genotypes grown on soils with low micronutrient availability due to chemical or biological fixation, or spatial or temporal unavailability, micronutrient-efficient genotypes have greater yield in comparison to inefficient genotypes even when fertilized with smaller amounts or less frequently [ 58 ]. The importance of genotype on differential micronutrient efficiency has been previously reported and discussed in detail [ 59 , 60 , 61 ]. The current research demonstrated that several CS lines had higher concentration of micronutrients compared to the parent TM-1 line, suggesting the potential association of the substituted chromosome or chromosome segment pair of the traits of interest.…”

Micronutrients are essential for plant growth and development, and important for human health nutrition and livestock feed. Therefore, the discovery of novel germplasm with significant variability or higher micronutrients content in crop seeds is critical. Currently, there is no information available on the effects of chromosome or chromosome arm substitution in cotton on cottonseed micronutrients. Thus, the objective of this study was to evaluate the effects of chromosome or chromosome arm substitution on the variability and levels of micronutrients B, Fe, Cu, Zn, Mn, and Ni in cottonseed from chromosome substitution (CS) cotton lines. Our hypothesis was that interspecific chromosome substitution in cotton can affect cottonseed micronutrients content, resulting in significant differences and variabilities of these nutrients among CS lines and between CS lines and the controls. Nine CS lines were grown in two-field experiments at two locations (in 2013 in South Carolina, USA; and in 2014 in Mississippi, USA). TM-1 (the recurrent parent of the CS line) and AM UA48 (cultivar) were used as control. The results showed significant variability among CS lines compared to the controls AM UA48 and TM-1. For example, in South Carolina (SC), B concentration in cottonseed ranged from 10.35 mg kg−1 in CS-M02 to 13.67 mg kg−1 in CS-T04. The concentration of Cu ranged from 4.81 mg kg−1 in CS-B08sh to 7.65 mg kg−1 in CS-T02, and CS-T02 was higher than both controls. The concentration of Fe ranged from 36.09 mg kg−1 to 56.69 mg kg−1 (an increase up to 57%), and six CS lines (CS-B02, CS-B08sh, CS-M02, CS-M04, CS-T02, and CS-T04) had higher concentration than both controls in 2013. In 2014 at the Mississippi location (MS), similar observation was found with CS lines for micronutrients content. The CS lines with higher concentrations of these micronutrients can be used as a genetic tool toward QTL identification for desired seed traits because these lines are genetically similar with TM-1, except the substituted chromosome or chromosome segment pairs from the alien species. Chromosome substitution provides an effective means for upland cotton improvement by targeted interspecific introgression, yielding CS lines that facilitate trait discovery, such as seed micronutritional qualities, due to increased isogenicity and markedly reduced complexity from epistatic interactions with non-target alien chromosomes. The positive correlation between B, Cu, and Fe at both locations, between Ni and Mn, between Zn and Cu, and between Zn and Ni at both locations signify the importance of a good agricultural and fertilizer management of these nutrients to maintain higher cottonseed nutrient content.

“…In leaves, Cu was reduced by 32% and 40% at 250 and 500 mg/kg, respectively, compared with control. It has been reported that high levels of Zn can reduce Cu uptake, by an antagonist interaction [27], due to both elements sharing the same transporters [53].…”

Bean (Phaseolus vulgaris) plants were grown for 45 days in soil amended with either uncoated (Z-COTE) and coated (Z-COTE HP1) ZnO nanomaterials (NMs), bulk ZnO and ZnCl, at 0-500mg/kg. At harvest, growth parameters, chlorophyll, and essential elements were determined. None of the treatments affected germination and pod production, and only ZnCl at 250 and 500mg/kg reduced relative chlorophyll content by 34% and 46%, respectively. While Z-COTE did not produce phenotypic changes, Z-COTE HP1, at all concentrations, increased root length (∼44%) and leaf length (∼13%) compared with control. Bulk ZnO reduced root length (53%) at 62.5mg/kg and ZnCl reduced leaf length (16%) at 125mg/kg. Z-COTE, at 125mg/kg, increased Zn by 203%, 139%, and 76% in nodules, stems, and leaves, respectively; while at the same concentration, Z-COTE HP1 increased Zn by 89%, 97%, and 103% in roots, stems, and leaves, respectively. At 125mg/kg, Z-COTE HP1 increased root S (65%) and Mg (65%), while Z-COTE increased stem B (122%) and Mn (73%). Bulk ZnO and ZnCl imposed more toxicity to kidney bean than the NMs, since they reduced root and leaf elongation, respectively, and the concentration of several essential elements in tissues.

“…Plants generally absorb Zn as a divalent cation (Zn ++ ). Zinc is required in protein biosynthesis and carbohydrate metabolism, and plays an important role in gene expression related to environmental stress [5,6]. Although Zn is required by plants for optimal metabolism, the efficiency of this micro-element depends on its absorption and translocation [7].…”

The physiological responses of habanero pepper plants (Capsicum chinense Jacq.) to foliar applications of zinc sulphate and zinc nano-fertilizer were evaluated in greenhouse trials. The effect of the supplement on fruit quality of habanero pepper was particularly observed. Habanero pepper plants were grown to maturity, and during the main stages of phenological development, they were treated with foliar applications of Zn at concentrations of 1000 and 2000 mg L−1 in the form of zinc sulfate (ZnSO4) and zinc oxide nanoparticles (ZnO NPs). Additional Zn was not supplied to the control treatment plants. ZnO NPs at a concentration of 1000 mg L−1 positively affected plant height, stem diameter, and chlorophyll content, and increased fruit yield and biomass accumulation compared to control and ZnSO4 treatments. ZnO NPs at 2000 mg L−1 negatively affected plant growth but significantly increased fruit quality, capsaicin content by 19.3%, dihydrocapsaicin by 10.9%, and Scoville Heat Units by 16.4%. In addition, at 2000 ZnO NPs mg L−1 also increased content of total phenols and total flavonoids (soluble + bound) in fruits (14.50% and 26.9%, respectively), which resulted in higher antioxidant capacity in ABTS (2,2′azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)), DPPH (2,2-diphenyl-1-picrylhydrazyl), and FRAP (ferric reducing antioxidant power) (15.4%, 31.8%, and 20.5%, respectively). These results indicate that application of ZnO NPs could be employed in habanero pepper production to improve yield, quality, and nutraceutical properties of fruits.
