Bacterial community composition in samples of 18 different treatments. Two types of soils were used: nutrient-rich soil (N) and continuous cropping field soil (F). Three developmental stages: seedling (s), budding (B), and flowering (F). Two cultivars: upland cotton (T) and sea island cotton (X), without cotton control (C). Each samples was labelled by a three-letter code, such as NsT indicates that seedling of sea island cotton grown in nutrient-rich soil. (A) Bacterial community composition by different treatments; (B) Proteobacteria, (C) Verrucomicrobia, (D) Planctomycetes, (E) Acidobacteria, (F) Actinobacteria, and (G) Bacteroidetes community composition in each sample. X-axis shown relative abundance, y-axis are different treatment.
