Antibiotic resistance in plant growth promoting bacteria: A comprehensive review and future perspectives to mitigate potential gene invasion risks

Abstract: Plant growth-promoting bacteria (PGPB) are endowed with several attributes that can be beneficial for host plants. They opened myriad doors toward green technology approach to reduce the use of chemical inputs, improve soil fertility, and promote plants’ health. However, many of these PGPB harbor antibiotic resistance genes (ARGs). Less attention has been given to multi-resistant bacterial bioinoculants which may transfer their ARGs to native soil microbial communities and other environmental reservoirs includ… Show more

“…53 While considered sustainable and environmentally friendly, the use of plant growth-promoting bacteria like Acidovorax in agriculture may pose a threat by facilitating the dissemination of ARGs in different environments. 54,55 For the resistome of the progeny rhizosphere, the organically produced seeds exclusively shared 14 ARGs and 1 MGE (mobA) with the progeny rhizosphere (Figure 4c). These 14 ARGs were candidate ARGs transferred from the seed endosphere to another rhizosphere via the seed.…”

“…Acidovorax has been identified as a core genus in plant-microbiome interactions because of its ability to promote root growth and manipulate plant hormones . While considered sustainable and environmentally friendly, the use of plant growth-promoting bacteria like Acidovorax in agriculture may pose a threat by facilitating the dissemination of ARGs in different environments. , …”

“…This is a very promising green technology that can replace or minimize chemical fertilizer use in agriculture. Nevertheless, recently many authors have pointed out that PGPB used as bioinoculants may enhance antibiotic resistance genes (ARGs) spread in soil because those microorganisms harbor ARGs very often (Chen et al 2019;Mahdi et al 2022; Zhang et al 2020). ARGs can be located on mobile genetic elements (MGE) and they can be easily transferred among indigenous bacteria by horizontal gene transfer (HGT) (Arber 2014;Forsberg et al 2012).…”

“…Moreover, multidrug resistant strains or human pathogens should be excluded. Finally, standard criteria, regulations and quality control procedures for biofertilizer candidates should be established, so as to guarantee environmental and public health protection (Mahdi et al 2022).…”

“…It is well known that most of the rhizospheric microbes carry antibiotic resistance (Mahdi et al, 2022), but the use of antibiotics is inevitable (Stockwell and Duffy, 2012). The use of antibiotic-selective PGPM can provide assistance in plant growth promotion in case of unprecedented bacterial infections.…”
