Abstract

fetched live from OpenAlex

Background: Recently, researches have begun to investigate the microbial communities associated with halophytes.Both rhizobacterial community composition and the environmental drivers of community assembly have been addressed.However, few studies have explored the structure of rhizobacterial communities associated with halophytic plants that are co-occurring in arid, salinized areas.Methods: Five halophytes were selected for study: these co-occurred in saline soils in the Ebinur Lake Nature Reserve, located at the western margin of the Gurbantunggut Desert of Northwestern China.Halophyte-associated bacterial communities were sampled, and the bacterial 16S rDNA V3-V4 region amplified and sequenced using the Illumina Miseq platform.The bacterial community diversity and structure were compared between the rhizosphere and bulk soils, as well as among the rhizosphere samples.The effects of plant species identity and soil properties on the bacterial communities were also analyzed.Results: Significant differences were observed between the rhizosphere and bulk soil bacterial communities.Diversity was higher in the rhizosphere than in the bulk soils.Abundant taxonomic groups (from phylum to genus) in the rhizosphere were much more diverse than in bulk soils.Proteobacteria, Firmicutes, Actinobacteria, Bacteroidetes and Planctomycetes were the most abundant phyla in the rhizosphere, while Proteobacteria and Firmicutes were common in bulk soils.Overall, the bacterial community composition were not significantly differentiated between the bulk soils of the five plants, but community diversity and structure differed significantly in the rhizosphere.The diversity of Halostachys caspica, Halocnemum strobilaceum and Kalidium foliatum associated communities was lower than that of Limonium gmelinii and Lycium ruthenicum communities.Furthermore, the composition of Halostachys caspica and Halocnemum strobilaceum communities was very

Direct model labels (unvalidated)

Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
