The objective of the investigation was to improve phosphate solubilization in tomato plants by Bacillus licheniformis, a rhizobacterium that promotes plant growth. Ultraviolet (UV) radiation, Ethyl methanesulfonate (EMS) and Ethidium bromide (EtBr) mutagenesis produced twenty-one mutants. Phosphate solubilization was higher in the PM7 (physical mutant) (121.00 g mL) than in the wild type (82.00 g mL). PM7 showed high antifungal activity against Phytophthora capsici, Fusarium oxysporum and Dematophora necatrix besides increased siderophore production and HCN production. In a net-house experiment, PM7 improved root and shoot parameters, P assimilation and soil P availability in tomato plants. This study demonstrates the potential of PM7 as an effective rhizobacterium for enhancing nutrient availability and plant growth.
本研究的目的是通过地衣芽孢杆菌（一种促进植物生长的根际细菌）来提高番茄植株的磷溶解能力。紫外线（UV）辐射、甲基磺酸乙酯（EMS）和溴化乙锭（EtBr）诱变产生了21个突变体。PM7（物理突变体）的磷溶解能力（121.00 μg/mL）高于野生型（82.00 μg/mL）。除了增加铁载体产量和HCN产量外，PM7对辣椒疫霉、尖孢镰刀菌和立枯丝核菌具有高抗真菌活性。在网室试验中，PM7改善了番茄植株的根和地上部参数、磷吸收以及土壤磷有效性。本研究证明了PM7作为一种有效的根际细菌在提高养分有效性和促进植物生长方面的潜力。
