“…In the present study, the physiological and biochemical aspects of maize plants sprayed with Ni and infected by E. turcicum were investigated in detail to shed light on the role of this micronutrient in the potentiation of maize resistance against NCLB. The Ni spray reduced NCLB symptoms on maize leaves showing its potential for disease management, as reported for other interactions such as pecan-F. effusum as well as soybean-M. diffusa and soybean-P. pachyrhizi (Barcelos et al, 2018;Einhardt et al, 2020aEinhardt et al, , 2020bWood et al, 2012).…”

“…For inoculated +Ni plants, CHI activity significantly increased by 33%, 32%, 69%, and 117% at 4, 8, 12, and 16 dai, respectively, compared to noninoculated +Ni plants (Figure 12a,b).

“…For instance, severities of scab (Fusicladium effusum) in pecan and powdery mildew (Microsphaera diffusa) and soybean rust (Phakopsora pachyrhizi) in soybean were reduced by Ni (Barcelos et al, 2018;Einhardt et al, 2020aEinhardt et al, , 2020bWood et al, 2012). According to Barcelos et al (2018), lower powdery mildew severity on the leaves of soybean plants sprayed with Ni was linked to its direct effect against conidia and mycelia of M. diffusa over the leaf surface and higher activities of antioxidative enzymes (e.g., catalase, peroxidase, and superoxide dismutase).…”

Maize resistance to northern corn leaf blight is potentiated by nickel

Many diseases greatly impact maize production worldwide, and northern corn leaf blight (NCLB), caused by the fungus Exserohilum turcicum (syn. Setosphaeria turcica) (Leonard & Suggs, 1974) stands out as one of the most important (Munkvold & White, 2016). The symptoms of NCLB are long elliptical, greyish-green or tan lesions, mainly in older leaves of maize plants (Kotze et al., 2019). The necrotic and larger NCLB lesions negatively affect leaf gas exchange (net assimilation rate, stomatal conductance to water vapour, transpiration rate, and internal CO 2 concentration) and chlorophyll (Chl) a fluorescence (maximum quantum yield of photosystem [PS] II, and effective quantum yield of PS II) parameters (Silveira et al., 2019).Moreover, higher electrolyte leakage and greater concentrations of hydrogen peroxide and malondialdehyde occur at the necrotrophic phase of E. turcicum infection in maize leaves (Silveira et al., 2019).Cultural practices such as crop rotation, use of resistant genotypes, and application of foliar fungicides have been used by growers to reduce the impact of NCLB on maize yield (Nelson et al., 2018).Sustainable methods that can be integrated with cultural strategies are needed to ensure cost-effective NCLB control and less environmental impact. Mineral nutrition stands out as an effective strategy

“…These changes probably reflect the inability of the plants to regulate their photoprotection mechanisms, resulting in greater photooxidative damage in the infected tissues (Rolfe and Scholes 2010). Similarly to the findings of Einhardt et al (2020 b), the decrease in the ETR values for inoculated plants accompanied the lower F v /F m and Y(II) values, indicating the occurrence of photochemical dysfunctions and that the photoprotection mechanism was inefficient for avoiding damage in the photosynthetic apparatus, as reported by Klughammer and Schereiber (2008).…”

Asian soybean rust (ASR), triggered by Phakopsora pachyrhizi, can cause great yield losses on soybean and nickel (Ni) has potential to control this disease. This study evaluated the effect of using soybean seeds with different Ni contents on ASR control by performing two experiments. In experiment 1, seeds with different Ni contents were obtained by spraying plants three times with solutions containing either 60 or 100 gNi•ha -1 . Plants sprayed with water served as the control treatment. In experiment 2, plants originated from seeds obtained in experiment 1 (T1 = 0.9 μgNi•seed -1 , T2 = 1.2 μgNi•seed -1 , and T3 = 1.6 μgNi•seed -1 ) were inoculated with P. pachyrhizi at the V4 growth stage. The ASR severity was evaluated 16 days after inoculation (DAI) and the chlorophyll (Chl) a fluorescence parameters at 8 and 16 DAI. The ASR severity decreased by 64 and 47% for treatments T2 and T3, respectively, in comparison to T1 treatment. The photosynthetic apparatus was negatively affected by ASR. The efficiency of the use of light by photosystem II decreased while the energy dissipated by nonregulated form increased in the infected leaflets. There was no significant difference for Chl a fluorescence parameters for T1, T2, and T3 treatments applied to inoculated plants probably due to the biotrophic lifestyle of P. pachyrhizi associated with lower ASR severity. In conclusion, the potential of using seeds with higher Ni content as a tool for ASR integrated management control is highlighted in this study.

Bu araştırmada, brokoli bitkisinin tohum ve fidelerinde değişen konsantrasyonlardaki nikelin etkisi ve birikimi incelenmiştir. Tohumlarda çimlenme yüzdesi, bitkinin kök-gövde uzunlukları, ağırlık miktarları, klorofil, karotenoid, total çözünebilir protein ile MDA içerikleri, POD aktiviteleri ve Ni birikimi belirlenmiştir. 100 μM NiSO4 ün tohumlarda çimlenmeyi inhibe ettiği gözlenmiştir. Ni'nin büyümeyi etkilediği, ağırlık miktarlarında da değişikliklere neden olduğu belirlenmiştir. 9 günlük fidelerin klorofil içerikleri 1 μM NiSO4 de artarken, 30 günlük fidelerde ise 0.1 μM NiSO4 de artış tespit edilmiştir. Fidelerdeki total çözünebilir protein içeriğinde 10 ve 100 μM NiSO4 de azalışlar gözlenirken, POD aktivitesinde artışlar gözlenmiştir. Ayrıca, nikelin özellikle köklerde biriktiği belirlenmiştir. Nikelin brokolinin çimlenme ve büyüme-gelişmesi üzerine olan etkileri ile ilgili olarak, düşük konsantrasyonlardan (0.01, 0.1 ve 1 μM) bitkinin olumlu etkilendiği, yüksek konsantrasyonların ise (10 ve 100 μM) toksik etkilere neden olduğu tespit edilmiştir.
