“…Nevertheless, it is reported the risks of toxicity in the field, especially in soils with high sand contents (PRADO, 2008), such as of the present study (Table 2). Excess B causes reductions in the productivity of agricultural areas, including the United States, Australia and South Africa (AQUEA et al, 2012;KAYIHAN et al, 2016). The increase in the contents of B in the soil decreased the seed production of three of the four soybean varieties grown in Turkey (HAMURCU et al, 2019).…”

Due to the increasing national and international demand, the cultivation of açaí palm trees (Euterpe oleracea Mart.) has expanded to upland areas in Brazil. Most of these areas present low natural soil fertility, in which boron (B) is one of the most limiting nutrients. This study aimed to evaluate the productivity of fresh fruits of fertigated açaí trees submitted to doses of B. The study was carried out in Tomé-Açu, northeastern Pará, Brazil. The experimental design consisted of randomized blocks with four treatments: control and addition of 20, 40 and 60 g of B clump-1. After 17 months, bunches of fresh fruits were collected and the production per hectare was estimated. An economic analysis was carried out considering the costs of fertilization and fruit production. The productivities obtained in the treatments were considered above the average of the municipality of Tomé-Açu. The estimated content of leaf B that provided the highest productivity was 14.9 mg kg-1, for a yield of 5479 kg ha-1 year-1¸ while the critical content corresponded to 13.2 mg kg-1. The highest productivity of fresh açaí fruits was achieved with the dose of 20 g of B clump-1, which provided a net gain of 42%.

“…Excessive fertilization with B is known to decrease the productivity of agricultural production (AQUEA et al, 2012;KAYIHAN et al, 2016;HAMURCU et al, 2019;NAZIR et al, 2019). In açaí trees in the state of Pará, fertilization with B has been randomly adopted, which negatively affects production (RIBEIRO, 2017).…”

“…Although boron (B) is an essential micronutrient for plants (Warington, 1923), high levels of B are a crucial problem for crops, mainly in arid areas in the world (Landi et al, 2012). Along with many physiological defects, a toxic level of B can give rise to oxidative stress (El-Shintinawy, 1999;Ardıc et al, 2009;Kayıhan et al, 2016) that usually triggers an antioxidative response in plants. Changes in regulation of the enzymatic and nonenzymatic antioxidants under B toxicity have been examined in many plant species.…”

“…Changes in nonenzymatic and enzymatic components of the AsA-GSH cycle under B toxicity were mostly studied at the biochemical level in plants such as barley (Karabal et al, 2003), tomato (Cervilla et al, 2007), and chickpea (Ardıc et al, 2009). For this reason, in our previous report, we studied the enzymes of the AsA-GSH cycle at biochemical and transcriptional levels in order to gain better insight into the antioxidant machinery in Arabidopsis thaliana (Kayıhan et al, 2016). Accordingly, in addition to strong stimulation of SOD, a fine-tuned regulation of the AsA-GSH cycle under B toxicity was suggested (Kayıhan et al, 2016).…”

Recently, microarray and proteomic analyses have shown that many genes related to the GST superfamily and GST proteins were induced under excess B conditions in barley (Öz et al, 2009), wheat (Kayıhan et al, 2017), poplar (Yıldırım and Uylaş, 2016;Yıldırım, 2017), and Arabidopsis (Chen et al, 2014).…”

The fine-tuned regulation of the Halliwell-Asada cycle (ascorbate-glutathione pathway) in Arabidopsis thaliana under boron (B) toxicity was shown in our previous report. In this study, we investigated the expression levels of some members of the glutathione S-transferase (GST) superfamily, such as phi (GSTF2, GSTF6, GSTF7, and GSTF8), tau (GSTU19), and zeta (GSTZ1) classes in Arabidopsis thaliana that were exposed to 1 mM boric acid (1B) and 3 mM boric acid (3B). Additionally, the expression levels of genes for glutathione (GSH) and phytochelatin biosynthesis as well as miR169 and miR156 were evaluated in Arabidopsis thaliana exposed to 1B and 3B. Moreover, changes in the levels of total GST activity; GSH; and total, protein-bound, and nonprotein thiols were spectrophotometrically determined. GSH levels and nonprotein thiol content did not change significantly following both B-toxicity conditions. Expression levels of GSH1 and GSH2 stayed stable under 1B toxicity; however, GSH1 expression increased significantly under 3B conditions in Arabidopsis thaliana. The expression levels of four genes from phi class members of GST were not dramatically changed under B-toxicity conditions. However, the transcript levels of miR169, ATGSTU19, and ATGSTZ1 were significantly increased after 1B and 3B exposure. These GST genes may have a role in the dramatic increase of total GST activity under toxic B. To the best of our knowledge, this is the first report displaying an integrative view of high-B-induced regulation of GSH-dependent enzymatic machinery at different biological organization levels in Arabidopsis thaliana.
