Summary: Foliar application of CeO2 nanoparticles (NPs) can alleviate abiotic stress in crops. CeO2-NPs increase pigment content and antioxidative enzyme activity in cadmium-stressed plants, reducing Cd toxicity. Moreover, CeO2-NPs reduce Cd content in fruit and enhance fruit mineral elements and bioactive compounds.

Summary: Bacillus thuringiensis (Bt) has long been used in agriculture as an environmentally-friendly biopesticide due to its insecticidal proteins. However, recent studies suggest its potential as a biofertilizer for plant growth promotion and the development of transgenic plants. Its association with delta-endotoxins, especially cry proteins, give it its insecticidal properties. The review provides an overview of Bt's uses as a biocontrol agent against insect pests, its classification of cry proteins, mechanisms of action, incorporation into transgenic plants, and applications as a biofertilizer and biopesticide. Commercially available Bt formulations are considered efficient alternatives to chemical pesticides.

Summary: In this study, native strains of Bacillus species were isolated and evaluated for their efficacy in controlling Meloidogyne incognita in okra. Two Bacillus spp., Bacillus marisflavi CRB2 and Bacillus subtilis CRB7, were found to be most effective against M. incognita. These strains were also found to harbor multiple antimicrobial peptide genes, which may contribute to their efficacy against M. incognita. Under laboratory, pot, and field conditions, the application of B. marisflavi CRB2 and B. subtilis CRB7 significantly reduced the incidence of M. incognita in okra and increased yield. These findings suggest that these native Bacillus strains can be used as part of an integrated nematode management strategy.

Summary: Bacillus thuringiensis (Bt), used widely as a biological control agent, can have diverse and complex impacts on natural communities, affecting indigenous microorganisms, plants, and various organisms in the food chain. The extensive phenotypic plasticity of Bt strains and their potential off-target effects underscore the importance of assessing the safety of future Bt-based pesticides at multiple levels of ecosystem organization.

Summary: This study examined the accumulation potential of aluminum and barium in different parts of okra plants and their impact on growth and mineral nutrition. The results showed that aluminum promoted dry biomass production, while barium had a negative effect on growth and fructification yield. Okra plants preferentially accumulated these elements in the roots and exhibited reduced mineral uptake, especially in roots and shoots. In response to stress, the plants increased the levels of proline and total phenols, enhancing their adaptability.

Summary: This study found that exogenous GSH treatment can inhibit weight loss and alleviate browning in postharvest okra, maintaining the appearance and quality of the fruit. GSH treatment also reduces the levels of ROS and regulates redox homeostasis in okra. Therefore, exogenous GSH treatment can prolong the shelf life of okra.

Summary: Traditional agriculture is the largest food-producing sector globally, but it is closely associated with rural poverty. Socially adapted technologies, such as the use of humic substances as biostimulants, can enhance subsistence crop production and help impoverished farmers. This study evaluated the effect of a humic/PGPB mixed biostimulant on cassava and okra crops, improving plant development and increasing yields by 70% and 50% respectively. The use of biostimulants can contribute to food security and the autonomy of farmers, bridging traditional knowledge with modern science for sustainable agroecosystem management.

Summary: In this study, a highly productive keratinase mutant strain, UV25-4, was obtained through ultraviolet mutagenesis, which increased the feather degradation rate and keratinase activity significantly. The hydrolysate of UV25-4 also enhanced the growth and quality of Chinese cabbage. Comparative genomics analysis revealed SNPs and insertions/deletions in the mutant genome. These findings indicate that UV mutagenesis is an effective strategy to obtain efficient feather-degrading strains and feather hydrolysates can be used to improve the growth and quality of vegetables.

Summary: Studying the effects of fertilization on okra and soil nutrients, and establishing a reasonable compensation scheme for soil nutrients while improving saline soil through subsurface pipe drainage combined with okra is of great significance. The study compared the effects of chemical fertilizer + organic fertilizer (NPK+OM) treatment, organic fertilizer (OM) treatment, chemical fertilizer (NPK) treatment, and no fertilization (CK) treatment on okra's agronomic traits and soil nutrient content. Fertilization significantly improved okra's agronomic traits and effectively compensated soil nutrients. Among the different treatments, NPK+OM treatment had the best effect.

Summary: The aim of this study is to highlight the chemical and biological diversity of Abelmoschus esculentus L. Moench (okra). This plant contains vitamins, minerals, proteins, and carbohydrates, as well as flavonoids, terpenes, phenolic compounds, and sterols. These variations in the chemical composition result in various therapeutic activities, including antidiabetic, hypolipidemic, antioxidant, antimicrobial, anticancer, wound healing, hepatoprotective, immunomodulator, neuroprotective, gastroprotective, and cardioprotective activities.
