“…PGPB represent therefore a unique opportunity to develop ecofriendly and sustainable agricultural practices, a lofty goal that is especially relevant in the context of current global changes (Glick, 2012;Santoyo et al, 2016;Ramakrishna et al, 2019). For instance, such practices include the biotechnological use of PGPB as biofertilizers or biocontrol agents (De Silva et al, 2019;Leila and El-Hafid, 2020;Ünüvar and Ünlü, 2022). However, the effectiveness of most PGPB is highly influenced by climatic conditions, soil conditions, and microbe-microbe interactions, thereby deeply affecting their use in a wide range of agricultural conditions (Fageria and Stone, 2006;Gaiero et al, 2013;Rilling et al, 2019;Canfora et al, 2021).…”

By improving plant nutrition and alleviating abiotic and biotic stresses, plant growth-promoting bacteria (PGPB) can help to develop eco-friendly and sustainable agricultural practices. Besides climatic conditions, soil conditions, and microbe-microbe interactions, the host genotype influences the effectiveness of PGPB. Yet, most GWAS conducted to characterize the genetic architecture of response to PGPB are based on non-native interactions between a host plant and PGPB strains isolated from the belowground compartment of other plants. In this study, a GWAS was set up under in vitro conditions to describe the genetic architecture of the response of Arabidopsis thaliana to the PGPB Pseudomonas siliginis, by inoculating seeds of 162 natural accessions from the southwest of France with one strain isolated from the leaf compartment in the same geographical region. Strong genetic variation of plant growth response to this native PGPB was observed at a regional scale, with the strain having a positive effect on the vegetative growth of small plants and a negative effect on the vegetative growth of large plants. The polygenic genetic architecture underlying this negative trade-off showed suggestive signatures of local adaptation. The main eco-evolutionary relevant candidate genes are involved in seed and root development.

The social movement to reduce reliance on pesticides and synthesized fertilizers and the growing global demand for sustainable food supplies require the development of eco‐friendly and sustainable agricultural practices. In line, plant growth‐promoting bacteria (PGPB) can participate in creating innovative agroecological systems. While the effectiveness of PGPB is highly influenced by abiotic conditions and microbe–microbe interactions, beneficial plant–PGPB interactions can also highly depend on both host and PGPB genotype. Here, the state of the art on the extent of natural genetic variation of plant–PGPB interactions and the underlying genetic architecture, in particular in Arabidopsis thaliana is reviewed. Extensive natural plant genetic variation in response to PGPB is associated with a polygenic architecture and genetic pathways rarely mentioned as being involved in the response to PGPB. To date, natural genetic variation within PGPB is little explored, which may in turn allow the identification of new genetic pathways underlying benefits to plants. Accordingly, several avenues to better understand the genomic and molecular landscape of plant–PGPB interactions are introduced. Finally, the need for establishing thorough functional studies of candidate genes underlying Quantitative Trait Loci and estimating the extent of genotype‐by‐genotype‐by‐environment interactions within the context of realistic (agro‐)ecological conditions is advocated.
