grows in the sandy desert soil of the Arabian Peninsula with limited access to water, aside from occasional precipitation or dew. Understanding its ability to produce water-filled fruit and nutrient-rich seeds despite the harsh environment, can be useful for agricultural applications. However, information regarding the microbiome of is lacking. We hypothesized that associates with bacteria that aid its survival, like what has been observed in other desert plants. Here, we used 16S rRNA gene data to gain insight into the microbiome of to identify its associated bacteria. In total, 9818 and 6983 OTUs were generated from root, soil, and leaf samples combined. Overall, bulk soils had the highest alpha diversity, followed by rhizosphere and root zone soils. Furthermore, is associated with known plant-growth-promoting bacteria (including Acidobacteria, Bacterioidetes, and Actinobacteria), and interestingly a class of non-photosynthetic Cyanobacteria (Melainabacteria) that is more abundant on the inside and outside of the root surface than control samples, suggesting its involvement in the rhizophagy process. This study will provide a foundation for functional studies to further understand how -microbes interactions help them grow in the desert, paving the path for possible agricultural applications.
它生长在阿拉伯半岛的沙漠沙地土壤中，除了偶尔的降雨或露水外，获取水分的途径有限。了解它在恶劣环境下仍能产出水分充足的果实和营养丰富的种子的能力，可能对农业应用有所帮助。然而，关于它的微生物群落的信息却很缺乏。我们推测它与有助于其生存的细菌有关联，就像在其他沙漠植物中观察到的那样。在这里，我们使用16S rRNA基因数据来深入了解它的微生物群落，以识别其相关细菌。从根、土壤和叶样本中总共产生了9818个和6983个操作分类单元（OTU）。总体而言，大块土壤的α多样性最高，其次是根际土壤和根区土壤。此外，它与已知的促进植物生长的细菌（包括酸杆菌门、拟杆菌门和放线菌门）有关联，有趣的是，一类非光合蓝细菌（黑素杆菌纲）在根表面内外比对照样本中更为丰富，这表明它参与了根际摄食过程。这项研究将为功能研究提供基础，以进一步了解它与微生物的相互作用如何帮助它们在沙漠中生长，为可能的农业应用铺平道路。
