Principal-coordinates analysis of 16S rRNA gene clone libraries of rice shoot-associated bacteria under ambient (AMBI) and FACE conditions. The ordinations were separately constructed for leaf blades (A, B) and leaf sheaths (C, D) using UniFrac distances weighted by the relative abundance. NT, normal surface water and soil temperature with standard nitrogen fertilization; ET, elevated surface water and soil temperature (+2°C from NT) with standard nitrogen fertilization; LN, NT with no nitrogen fertilization. The arrow indicates a community shift described in the text. The shaded circle emphasizes the high similarity of community structures between the control (AMBI-NT) and FACE-ET.
