*P < 0.05; **P < 0.01; NS: not significant. Abbreviation: AI, acid invertase; AMF, arbuscular mycorrhizal fungus; DS, drought stress; NI, neutral invertase; OAT, ornithine-δ-aminotransferase; P5CR, Δ₁-pyrroline-5-carboxylate reductase; P5CS, Δ_1-pyrroline-5-carboxylate synthetase; ProDH, proline dehydrogenase; RWC, relative water content; SPS, sucrose phosphate synthase; SS, sucrose synthase (degrading direction); WW, well watered.
