Other claims from this paper (9)
- Association Alpha diversity declined progressively from bulk soil to rhizosphere soil, root and shoot.
- Association Beta diversity showed clear compartmental separation driven by environmental factors.
- Association Canonical correspondence analysis identified electrical conductivity, Na2O, K2O and carbonate fractions as the main abiotic drivers.
- Observation 66% of amplicon sequencing variants were shared across compartments.
- Observation Host identity played a secondary role, as environmental filtering overshadowed host-specific associations.
- Observation Culture-dependent isolation recovered 19 halophilic and halotolerant bacterial strains.
- Observation The isolates grew robustly on saline Marine Agar, indicating strong salt tolerance.
- Observation The cultured isolates and the metabarcoding profile showed strong concordance.
- Mechanism Sabkha plant microbiomes are primarily shaped by deterministic abiotic filtering.
