The microbial symbiosis of Rosemary

Breeding Rosemary (Rosmarinus officinalis) is prized for its rich content of bioactive compounds, including polyphenols (ferulic acid, carnosol, rosmarinic acid), essential oils, and triterpenic acids, which confer antioxidant, antimicrobial, and therapeutic properties. These metabolites are influenced not only by genetic and environmental factors but also by complex interactions with soil microorganisms. Rosemary engages in symbiotic relationships with microorganisms that significantly influence its metabolic profile, enhancing both growth and bioactive compound production. These interactions involve arbuscular mycorrhizal (AM) fungi and rhizospheric bacteria, which modulate the plant's secondary metabolism and offer biostimulatory benefits. Below is a synthesis of key findings on these symbiotic relationships and their biochemical implications.
