The present study aimed at systematically investigating the endophytic communities of dominant plants in the karst ecosystem. Soil and plant materials were collected and after sequencing of the 16 s RNA, the diversity and abundance of the endophytic community structures in leaves were examined. Our results showed that abundant and diverse endogenous bacteria were associated with the leaves of common dominant plants living in the karst ecological environment. Notably, common traits and significant differences in the endophytic community structures were recorded among different plant species with different leaf grown in soils with different calcium contents. These observations implied that plants may adopt different strategies to adapt to the karst ecological environment. In addition, the endophytic bacteria associated with the leaves may be involved in different physiological strategies used by the plants to adapt to the karst ecological environment. These findings provide new avenues for developing microbial agents that could be suitable for the karst ecological environment and will provide sustainable solutions for improving the ability of plants to adapt to karst special adversities, and thus for karst geomorphological environmental protection and agricultural development.
本研究旨在系统地研究喀斯特生态系统中优势植物的内生群落。采集土壤和植物材料，对 16s RNA 进行测序后，检测了叶片内生群落结构的多样性和丰度。研究结果表明，丰富多样的内生细菌与生活在喀斯特生态环境中的常见优势植物的叶片相关。值得注意的是，不同植物物种的叶片内生群落结构存在共同特征和显著差异，而这些植物生长的土壤中钙含量也不同。这些观察结果表明，植物可能采用不同的策略来适应喀斯特生态环境。此外，与叶片相关的内生细菌可能参与了植物适应喀斯特生态环境的不同生理策略。这些发现为开发适合喀斯特生态环境的微生物制剂提供了新途径，为提高植物适应喀斯特特殊逆境的能力提供了可持续的解决方案，从而为喀斯特地貌环境保护和农业发展提供了可持续的解决方案。
