Other claims from this paper (16)
- Intervention effect Drought reduced root colonization rate and soil mycelium length of the mycorrhizal fungus.
- Intervention effect Under drought, mycorrhizal plants showed mitigated declines in water use efficiency and photosynthetic efficiency.
- Intervention effect Mycorrhizal plants had enhanced net photosynthetic rate and photochemical quantum efficiency (maximum and steady-state) under drought.
- Intervention effect Mycorrhizal plants under drought had elevated leaf phosphorus and iron.
- Intervention effect Mycorrhizal plants under drought had elevated root phosphorus and calcium levels.
- Intervention effect Mycorrhizal plants had significantly higher root H+ efflux, increased NH4+ levels and elevated H+-ATPase activity in leaves and roots, regardless of moisture regime.
- Intervention effect Mycorrhizal plants showed a notable decrease in soil pH regardless of moisture regime.
- Observation Nine PtAHA genes encoding plasma membrane H+-ATPases were identified in trifoliate orange.
- Observation PtAHA1/4/8/9 were predominantly expressed in roots, with distinct tissue-specific expression patterns among the PtAHA genes.
- Intervention effect Mycorrhizal colonization triggered tissue-specific expression of PtAHA genes.
- Intervention effect Drought triggered tissue-specific expression of PtAHA genes.
- Intervention effect PtAHA8 was upregulated in leaves and roots under drought.
- Association Most leaf PtAHAs were closely associated with mycorrhizal colonization and H+-ATPase activity.
- Association In roots, seven PtAHAs were linked to H+-ATPase activity.
- Association PtAHA8 was identified as a central player associated with root H+-ATPase activity under combined drought and mycorrhizal conditions.
- Mechanism The authors conclude that mycorrhizas enhance drought tolerance in trifoliate orange through PtAHA-driven proton extrusion.
