The rhizosphere microbiome of burned holm-oak: potential role of the genus Arthrobacter in the recovery of burned soils

Abstract After a forest wildfire, the microbial communities have a transient alteration in their composition. The role of the soil microbial community in the recovery of an ecosystem following such an event remains poorly understood. Thus, it is necessary to understand the plant-microbe interactions...
