Bacillus biocontrol agent(s) BCA(s) such as Bacillus cereus, Bacillus thuringiensis and Bacillus subtilis have been widely applied to control insects' pests of plants and pathogenic microbes, improve plant growth, and facilitate their resistance to environmental stresses. In the last decade, researchers have shown that, the application of Bacillus biocontrol agent(s) BCA(s) optimized agricultural production yield, and reduced disease risks in some crops. However, these bacteria encountered various abiotic stresses, among which ultraviolet (UV) radiation severely decrease their efficiency. Researchers have identified several strategies by which Bacillus biocontrol agents resist the negative effects of UV radiation, including transcriptional response, UV mutagenesis, biochemical and artificial means (addition of protective agents). These strategies are governed by distinct pathways, triggered by UV radiation. Herein, the impact of UV radiation on Bacillus biocontrol agent(s) BCA(s) and their mechanisms of resistance were discussed.
芽孢杆菌生物防治剂 (BCA) 如蜡状芽孢杆菌、苏云金芽孢杆菌和枯草芽孢杆菌已被广泛应用于防治植物虫害和病原微生物，促进植物生长，并提高其对环境胁迫的抗性。在过去的十年中，研究人员表明，芽孢杆菌生物防治剂的应用优化了农业生产产量，并降低了一些作物的疾病风险。然而，这些细菌遇到了各种非生物胁迫，其中紫外线 (UV) 辐射严重降低了它们的效率。研究人员已经确定了几种芽孢杆菌生物防治剂抵抗 UV 辐射负面影响的策略，包括转录反应、UV 诱变、生化和人工手段（添加保护剂）。这些策略由不同的途径控制，由 UV 辐射触发。本文讨论了 UV 辐射对芽孢杆菌生物防治剂及其抗性机制的影响。
