The Abundance and Diversity of Soil Fungi in Continuously Monocropped Chrysanthemum

Figure 2

DGGE profiles of 18S rDNA fragments present in DNA extracted from bulk soil (lanes 1–6) and rhizosphere (lanes 7–12) sampled at various developmental stages of growing chrysanthemum plants. Lanes 1, 2, 7, and 8: seedling stage, lanes 3, 4, 9, and 10: vegetative stage, and lanes 5, 6, 11, and 12: reproductive stage. Fragments excised for sequencing are indicated by numbers (Table 2).
