Fig. 2From: Comparative study of microbial structure and functional profile of sunflower rhizosphere grown in two fieldsRarefaction curves show the estimated richness in the rhizosphere soils and sampling effort. The total number of OTUs measured after sampling is represented on the y-axis, while the number of sequences is represented on the x-axis.
