Heliotropium arboreum is a resilient plant species found in coastal and isolated environments, particularly in the South China Sea and Hainan Province. This study explores the ecological dynamics of H. arboreum, focusing on its microbial community composition and diversity across various islands in these regions. The study investigates how environmental factors, such as soil pH, nutrient availability (nitrogen and phosphorus), and geographical isolation, influence the structure of bacterial and fungal communities associated with the plant. Bacterial communities were predominantly composed of Proteobacteria, with significant presence of Planctomycetota and Acidobacteriota, while fungal communities were mainly dominated by Ascomycota, with contributions from Basidiomycota and other groups. Significant positive correlations were observed between specific bacterial genera, such as Bryobacter (0.810***), Stenotrophobacter (0.496***), Pirellula (0.639***), and Phyllobacterium (0.708***), with nutrient availability, while Stenotrophomonas showed a negative correlation (-0.488***). In fungal communities, Preussia (0.585***) and Metacordyceps (0.616***) were positively correlated with higher nutrient levels. These findings emphasize the critical role of nutrient availability in shaping microbial communities and highlight its impact on the ecological success of H. arboreum in these harsh ecosystems.
