Nutrient deficiencies are a major problem that is prone to affect millions of people around the globe. Biofortification, a process of enriching nutrients in staple food crops is an effective method to tackle this malnutrition-associated disorder. Tomato () is a globally consumed crop and therefore is a suitable candidate for biofortification. Many plant growth-promoting bacteria are reported to have the ability to enhance nutrient content in plants. In the present study, we have investigated the ability of two bacterial consortia (consortia-1 -co-culturing sp. strain VITKC-5 and Sp. strain VITKC_6; and consortia-2 -co-culturing sp. strain VITKC-5 and sp. strain VITVLC-4) in the nutrient enrichment of tomato fruits. The results were then correlated with the elevated expression of nutrient transporter genes. Furthermore, the effect of these bacterial formulations on the indigenous microbiome has also been evaluated through metagenomic analysis. The application of bacterial formulations significantly improved the nutrient content when compared to the control (untreated) group. These findings advocate that PGPB-assisted biofortification has the potential to alleviate nutrient deficiency in humans.
营养缺乏是一个主要问题，容易影响全球数百万人。生物强化是一种在主食作物中富集营养的过程，是解决这种与营养不良相关疾病的有效方法。番茄（）是一种全球消费的作物，因此是生物强化的合适候选对象。据报道，许多促进植物生长的细菌有能力提高植物中的营养含量。在本研究中，我们研究了两种细菌联合体（联合体-1——共培养sp.菌株VITKC-5和Sp.菌株VITKC_6；以及联合体-2——共培养sp.菌株VITKC-5和sp.菌株VITVLC-4）在番茄果实营养富集方面的能力。然后将结果与营养转运蛋白基因的表达升高进行关联。此外，还通过宏基因组分析评估了这些细菌制剂对本地微生物群的影响。与对照组（未处理）相比，细菌制剂的应用显著提高了营养含量。这些发现表明，植物生长促进细菌辅助的生物强化有潜力缓解人类的营养缺乏。
