Figure 1. T-RFLP profiles for the rhizomes of Alpinia officinarum Hance plants at various ages.

The profiles were produced via either HhaI or MspI mono-digestion T-RFLP method targeting amplified fungal rDNA ITS sequences from the rhizomes of 1- to 4-year-old A. officinarum Hance planted at site LT. The T-RFLP analysis was repeated in three independent samples for each year, and the representative T-RFLP profiles are shown.
