AB Cork oak (Quercus suber L.) form low-density silvopastoral systems of great ecosystemic and socioeconomicimportance in the Mediterranean Basin, as they provide bark of great industrial value. Since the 1950s, thesetrees have been increasingly suffering from a deadly disorder known as decline, due to different biotic and abioticfactors. Associated with these forests, grasslands of great pastoral value and as carbon sequestrators develop. Theaim of this work was to study the bacterial and fungal diversity present in the soils of healthy and diseased corkoaks (due to decline) and their associated grasslands, an ecosystem whose microbiome has not been studied so farby metagenomics. Soil samples were collected from cork oak forests in southern Spain and their microbial di-versity was analyzed by metabarcoding with Illumina MiSeq. With respect to bacterial families, no differenceswere reported between cork oak forest soils and their associated grasslands, possibly due to the presence ofendemic bacteria and similar environmental conditions. However, there were differences in fungal diversitybetween healthy cork oak forests and their associated grasslands. In the healthy cork oak soils, the familiesGemmatimonadaceae and Nocardioidaceae were massively present, while in the diseased soils the fungal genusGeminibasidium was found. Regarding the functional niche, healthy cork oaks presented mainly ectomycorrhizaein their soils, while their associated grasslands presented fungal endophytes, less present in areas with diseasedtrees. Therefore, fungi, but not bacteria, present in the soils of cork oaks and associated grasslands could play akey role in the presence/absence of decline in cork oaks.
