<i>Tuber indicum</i> colonization enhances plant drought tolerance by modifying physiological, rhizosphere metabolic and bacterial community responses in <i>Pinus armandii</i>.

ABSTRACT: Tuber indicum has been extensively investigated in the fields of ecology, mycorrhizal synthesis with various plant species, and cultivation. Its impacts on plant physiological and metabolic responses under different water regimes remain unclear. Here, T. indicum colonized Pinus armandii seedlings were used to assess plant physiological responses, rhizosphere metabolomic profiles, and microbial community dynamics under differential water regimes. The results showed that T. indicum colonization significantly increased the contents of chlorophyll a and total pigments, but decreased the malondialdehyde content in the leaves under moderate drought stress. Under moderate and severe drought stresses, the diversity of the mycorrhizosphere bacterial community in the T
