“…This governing mechanism is instrumental in regulating a wide array of physiological activities and microbial phenotypes such as biofilm formation, pathogenicity, conjugation, secretion of hydrolytic enzymes, and production of antibiotic and secondary metabolites, increasing rhizosphere competence that leads to successful colonization [42]. Common examples of lipids that act as QS signals are N-acyl homoserine lactones (AHL) [FA] [39], diffusible signal factor (DSF) family [FA], and the more recently discovered pyrones and dialkylresorcinols [PK] from gram-negative bacteria [43][44][45][46]. There are also antimicrobial lipids released at low concentrations, as well as alcohols from fungal species (mostly Ascomycetes), which are associated with developmental processes [34,47].…”

“…In addition to plant signaling chemicals, metabolic interactions between microbes via quorum sensing (QS) are crucial in defining microbial communities. According to extensive research, the QS molecule N-acyl homoserine lactone (AHL), produced by Gram-negative bacteria, not only acts as a signaling molecule within and between bacterial species but also between bacteria and plants, influencing thereby gene expression and functions related to plant development, stress response, and immunity (Schuhegger et al, 2006;Ferluga et al, 2008;Babenko et al, 2022). QS compounds, such as cis-2-unsaturated fatty acids, pyrones, alkyl quinolones, and dialkyl resorcinols have recently been discovered.…”

Plant-associated microorganisms play a key role in the future sustainability of terrestrial ecosystems. In nature, plants and their associated microbiome can form an assemblage of species, considered interacting metaorganisms or holobionts. Horticultural plants, including vegetables, fruit and berries, and ornamentals live in intimate association with complex and diverse microbial communities that have evolved a myriad of cooperative and competitive interaction mechanisms that shape the holobiont fitness. Nonetheless, our understanding of these interactions in shaping more complex microbial horticulture communities, along with their relevance for host growth, fitness, stress resilience, and health in a more natural context remains sparse. In this perspective, the holo-omic landscape that requires careful consideration of study design and integrates multi-omic data from both host and microbiota domains is a promising approach to unveil the interplay between the two to advance horticultural production. The analysis of horticulture (meta)-omics and phenotyping, along with mechanistic experiments in model systems, is revolutionizing research by enhancing our ability to understand the structure and core function of the plant-associated microbiome. These advancements are complemented by improvements in the throughput and accuracy of DNA sequencing, enabling us to delve deeper into the genomes of microbial communities. Yet, many challenges remain. We focus this review on the potential for holo-omics to generate a more holistic perspective of molecular networks, and we further discuss the implementation and current limitations of the holo-omic approach within microbial horticulture. We argue that holo-omics will pave the way to improve, from a horticultural perspective, food security and safety, sustainability, breeding practices, development of microbiota- and host-tailored horticultural crops’ health treatments and increasing production efficiency.

“…N-acyl homoserine lactone (N-AHL) has been majorly reported in various Gram-negative bacteria, including Burkholderia sp., Pseudomonas syringae , Pseudomonas putida , Pseudomonas chlororaphis , Erwinia sp., and Serratia sp. ( Table 1 ) [ 52 , 53 ]. As well as AHLs, a diverse range of signals have been reported in Gram-negative bacteria, i.e., fatty acid methyl esters, 2-alkyl-quinolones, furanone, and γ-butyrolactones [ 16 , 50 , 54 ].…”

Rhizospheric plant–microbe interactions have dynamic importance in sustainable agriculture systems that have a reduced reliance on agrochemicals. Rhizosphere signaling focuses on the interactions between plants and the surrounding symbiotic microorganisms that facilitate the development of rhizobiome diversity, which is beneficial for plant productivity. Plant–microbe communication comprises intricate systems that modulate local and systemic defense mechanisms to mitigate environmental stresses. This review deciphers insights into how the exudation of plant secondary metabolites can shape the functions and diversity of the root microbiome. It also elaborates on how rhizosphere interactions influence plant growth, regulate plant immunity against phytopathogens, and prime the plant for protection against biotic and abiotic stresses, along with some recent well-reported examples. A holistic understanding of these interactions can help in the development of tailored microbial inoculants for enhanced plant growth and targeted disease suppression.
