“…Boron plays a protective role against excessive ROS by maintaining membrane integrity, metabolic activity and enzymatic activity [ 13 ]. Supplementation of B decreased the H 2 O 2 content and as well as MDA content under salt stress [ 41 ]. Foliar applied B upregulated the Cl − transportation and protected plants from salt-induced oxidative stress [ 16 ].…”

“…Application of Se increased the APX, MDHAR, DHAR and GR activity under salt stress [ 22 ]. Supplementation of B under salt stress increased the enzymatic activity [ 41 ]. The combined application of Se+B was more effective than individual Se and B spray in enhancing the activity of MDHAR and GR under salt stress.…”

“…Previously, in various crops supplementation of Se at lower concentration increased the CAT activity under salt stress [ 10 , 29 , 43 , 44 ]. Application of B also increased the CAT activity under salt stress [ 41 ]. However, exogenous application of Se alone and with B, boosted the CAT activity in the salt-treated plant.…”

The present investigation was executed with an aim to evaluate the role of exogenous selenium (Se) and boron (B) in mitigating different levels of salt stress by enhancing the reactive oxygen species (ROS) scavenging, antioxidant defense and glyoxalase systems in soybean. Plants were treated with 0, 150, 300 and 450 mM NaCl at 20 days after sowing (DAS). Foliar application of Se (50 µM Na2SeO4) and B (1 mM H3BO3) was accomplished individually and in combined (Se+B) at three-day intervals, at 16, 20, 24 and 28 DAS under non-saline and saline conditions. Salt stress adversely affected the growth parameters. In salt-treated plants, proline content and oxidative stress indicators such as malondialdehyde (MDA) content and hydrogen peroxide (H2O2) content were increased with the increment of salt concentration but the relative water content decreased. Due to salt stress catalase (CAT), monodehydroascorbate reductase (MDHAR), dehydroascorbate reductase (DHAR), glyoxalase I (Gly I) and glyoxalase II (Gly II) activity decreased. However, the activity of ascorbate peroxidase (APX), glutathione reductase (GR), glutathione peroxidase (GPX), glutathione S-transferase (GST) and peroxidase (POD) increased under salt stress. On the contrary, supplementation of Se, B and Se+B enhanced the activities of APX, MDHAR, DHAR, GR, CAT, GPX, GST, POD, Gly I and Gly II which consequently diminished the H2O2 content and MDA content under salt stress, and also improved the growth parameters. The results reflected that exogenous Se, B and Se+B enhanced the enzymatic activity of the antioxidant defense system as well as the glyoxalase systems under different levels of salt stress, ultimately alleviated the salt-induced oxidative stress, among them Se+B was more effective than a single treatment.

“…Pamukova-97 genotipinde ise FB uygulaması tuz stresinin yol açtığı membran hasarını daha da artırmıştır (Şekil 3B). Bu sonuç antep fıstığı ile yapılan bir araştırma ile uyum göstermektedir [48]. Ayrıca yapılan uygulamalara verilen metabolik cevapların genotipe bağlı olarak değişiklik gösterdiğini ortaya koymaktadır.…”

Bu çalışmada farklı iki buğday (Triticum aestivum L.) genotipinde (Momtchil ve Pamukova-97) tuz stresi (150 mM NaCl) ve foliar bor (H 3 BO 3 ; 30 µM) uygulamalarının etkileşimleri incelenmiştir. Momtchil'de klorofil a ve toplam klorofil miktarı tuz stresi, foliar bor ve tuz+foliar bor uygulamalarından etkilenmemiş, klorofil b miktarı ise, muhtemelen yüksek toplam karotenoid ve serbest prolin miktarından dolayı, ilgili kontrollerle karşılaştırıldığında artış göstermiştir. Pamukova-97'de ise böyle koruyucu bir mekanizmanın bulunmaması nedeniyle foliar bor ve tuz+foliar bor uygulamaları fotosentetik pigment miktarının azalmasına yol açmıştır. Askorbat-glutatyon döngüsünün enzimleri ve süperoksit dismutaz aktivitesi tüm uygulamalar sonucunda indüklenmemiş ve buğday genotiplerinin yapraklarında hem belirgin derecede H 2 O 2 birikimi hem de yüksek MDA miktarı ile gösterildiği gibi membran hasarı belirlenmiştir. Sonuç olarak, bu çalışmada kullanılan, tuz stresi altındaki buğday genotiplerinde foliar bor uygulamalarının beklenen iyileştirici etkisinin gözlenemediği söylenebilir.

“…Salt stress has injurious effects on chlorophyll (Chl) biosynthesis as well as on the efficiency of photosynthesis. The photon energy, therefore, cannot be appropriately used by photosystems, and plants suffer from oxidative stress due to excess production of reactive oxygen species (ROS) [ 3 , 7 ]. Ionic/nutrient imbalances alter the biosynthesis or metabolism of essential metabolites and disrupt the activity of enzymes involved in biochemical and physiological processes, further exacerbating ROS generation and oxidative damage in plants under salinity [ 4 , 8 , 9 ].…”

Boron (B) performs physiological functions in higher plants as an essential micronutrient, but its protective role in salt stress is poorly understood. Soybean (Glycine max L.) is planted widely throughout the world, and salinity has adverse effects on its physiology. Here, the role of B (1 mM boric acid) in salt stress was studied by subjecting soybean plants to two levels of salt stress: mild (75 mM NaCl) and severe (150 mM NaCl). Exogenous B relieved oxidative stress by enhancing antioxidant defense system components, such as ascorbate (AsA) levels, AsA/dehydroascorbate ratios, glutathione (GSH) levels, the GSH and glutathione disulfide ratios, and ascorbate peroxidase, monodehydroascorbate reductase, and dehydroascorbate reductase activities. B also enhanced the methylglyoxal detoxification process by upregulation of the components of the glyoxalase system in salt-stressed plants. Overall, B supplementation enhanced antioxidant defense and glyoxalase system components to alleviate oxidative stress and MG toxicity induced by salt stress. B also improved the physiology of salt-affected soybean plants.
