“…OPCM mainly affected the activities of SOD, POD, and K + /Na + ratio in leaf, and the content of Na + , REC, and soluble sugar in root. For stem-girdling cottons, the content of K + and Na + in leaf were increased, and the content of Na + in root was decreased; moreover, the regulation effect of stem girdling on ion homeostasis in leaf and root was more prominent under saline stress, indicating that the regulation mechanism of ion homeostasis by stem girdling are different under saline stress and alkaline stress (Ma et al, 2020). Although stem girdling reduced the K + and Na + transport efficiency, the application of OPCM maintained the ion homeostasis in organs (An et al, 2019).…”

Soil salinization and alkalization greatly restrict crop growth and yield. In this study, NaCl (8 g kg−1) and Na2CO3 (8 g kg−1) were used to create saline stress and alkaline stress on cotton in pot cultivation in the field, and organic polymer compound material (OPCM) and stem girdling were applied before cotton sowing and at flowering and boll-forming stage, respectively, aiming to determine the effects of OPCM on K+ and Na+ absorption and transport and physiological characteristics of cotton leaf and root. The results showed that after applying the OPCM, the Na+ content in leaf of cotton under saline stress and alkaline stress were decreased by 7.72 and 6.49%, respectively, the K+/Na+ ratio in leaf were increased by 5.65 and 19.10%, respectively, the Na+ content in root were decreased by 9.57 and 0.53%, respectively, the K+/Na+ ratio in root were increased by 65.77 and 55.84%, respectively, and the transport coefficients of K+ and Na+ from leaf to root were increased by 39.59 and 21.38%, respectively. The activities of superoxide dismutase (SOD), catalase (CAT), and peroxidase (POD), and the relative electrical conductivity (REC) in cotton leaf were significantly increased, while the content of malondialdehyde (MDA) was decreased; but the changes in those in root were not significant. The boll weights were increased by 11.40 and 13.37%, respectively, compared with those for the control. After stem girdling, the application of OPCM still promoted the ion transport of cotton organs; moreover, the CAT activity in root was increased by 25.09% under saline stress, and the SOD activity in leaf and CAT in root were increased by 42.22 and 6.91%, respectively under alkaline stress. Therefore, OPCM can significantly change the transport of K+ and Na+ to maintain the K+ and Na+ homeostasis in leaf and root, and regulate physiological and biochemical indicators to alleviate the stress-induced damage. Besides, the regulation effect of OPCM on saline stress was better than that on alkaline stress.

“…High salt ion concentration and pH are some of the main characteristics of saline-alkali soil (Vestin et al 2006). Plants growing in saline-alkali soil were subjected to osmotic stress, that seriously affected plant growth and development, and even lead to its death (He et al 2018;Ma et al 2020). In order to cope with salt-alkali stress, plants have evolved a variety of mitigation strategies, such as synthesizing osmotic regulators, improving the antioxidant capacity of enzymes and selective absorption of ions (Zhu et al 1998;Ashraf and Foolad 2005;Zhang et al 2016).…”

Soil salinization has become one of the important factors affecting the sustainable development of agriculture. Among them, the soda-alkali soil composed of sodium carbonate (Na 2 CO 3 ) has a more serious impact on crops. In this study, 175 Brassica napus accessions from different sources were used as materials, combined with Brassica 60 K SNP chip data, and the root length traits of Brassica napus during germination under Na 2 CO 3 stress (0.15%) and control conditions were analyzed for genome-wide association (GWAS). GWAS analysis detected that 5 SNPs were significantly related to root length traits under stress conditions; a single SNP could explain 10.22-12.01% of the phenotypic variation. A total of 15 candidate genes related to Na 2 CO 3 stress resistance were identified upstream and downstream of significant SNPs, including cation exchange protein genes (CAX1), members of the zinc finger protein family (ZFHD1), peroxidase family proteins (POD), and transcription factors (MYB family and WRKY family), etc. The expression analysis of 5 candidate genes in extreme phenotypic materials showed that BnaA04g21850D (CAX1) and BnaA06g24040D (ACX5) were induced by Na 2 CO 3 stress in both materials; BnaA06g31200D (ZFHD1) and BnaC02g37590D (MYB60) were up-regulated expression in sensitive materials; BnaA04g21990D (POD) was up-regulated expression in alkali-tolerant materials, indicating that these candidate genes may be involved in the process of rapeseed response to Na 2 CO 3 stress. This study can provide a reference for in-depth analysis of the molecular mechanism of Na 2 CO 3 stress resistance in rapeseed.

For environment-friendly, safe and nonpersistent chemical control of a significant polyphagous insect pest, Helicoverpa armigera, discovery of growth-regulating xenobiotics can offer a sustainable alternative to conventional insecticides. For this purpose, chemically synthesized compounds to inhibit sterol carrier protein (SCP-2) function using in silico and in vivo assays were evaluated to estimate their impact on the survivals and lifetable indices of H. armigera. From nine chemically synthesized compounds, OA-02, OA-06 and OA-09 were selected for this study based on binding poses mimicking cholesterol, a natural substrate of sterol carrier protein and molecular dynamics simulations. In vivo bioassays revealed that all compounds significantly reduced the larval and pupal weight accumulations and stadia lengths. Subsequently, the pupal periods were prolonged upon treatment with higher doses of the selected compounds. Moreover, OA-09 significantly reduced pupation and adult emergence rates as well as the fertility of female moths; however, fecundity remained unaffected, in general. The life table parameters of H. armigera were significantly reduced when treated with OA-09 at higher doses. The population treated with 450 μM of OA-09 had the least net reproductive rates (Ro) and gross reproductive rate (GRR) compared to the control population. The same compound resulted in a declining survival during the early stages of development coupled with reduced larval and pupal durations, and fertility. These results have a significant implication for developing an effective and sustainable chemical treatment against H. armigera infestation.
