Vurali turcica is naturally grown in a limited area in Central Anatolia in Turkey and was categorized as a critically endangered plant in the Red Data Book of Turkish Plants. This study aimed to analyze whether the symbiotic and mutualistic relation between V. turcica rhizomes and present microflora in the habitat can be active on its distribution. Plant growth-promoting rhizobacteria (PGPRs) colonize the rhizosphere and promote plant growth and physiology. In this paper, the diversity of PGPRs of rhizomes of V. turcica was analyzed. Rhizome samples were obtained from the natural habitats of V. turcica by the workers of Nezahat Gökyiğit Botanical Garden, and bacterial isolation was conducted on the collected samples. MIS analysis, 16S rRNA, and 16S-23S rRNA ITS region sequencing were implemented, and as a result, Bacillus megaterium was found to be one of the most abundant bacterial species of the rhizomes of V. turcica based on nucleotide homology. This study is the first report on the identification of rhizobacterial species in V. turcica.
土耳其罂粟自然生长在土耳其安纳托利亚中部的一个有限区域，被列为土耳其植物红色数据书中的濒危植物。本研究旨在分析 V. turcica 根茎与其栖息地中现有微生物群之间的共生和互利关系是否能积极影响其分布。植物促生根际细菌（PGPR）定殖于根际，并促进植物生长和生理。在本文中，分析了 V. turcica 根茎的 PGPR 多样性。根茎样品由 Nezahat Gökyiğit 植物园的工作人员从 V. turcica 的自然栖息地中获得，并对收集的样品进行细菌分离。进行了 MIS 分析、16S rRNA 和 16S-23S rRNA ITS 区测序，结果发现根据核苷酸同源性，巨大芽孢杆菌是 V. turcica 根茎中最丰富的细菌物种之一。本研究是关于鉴定 V. turcica 根际细菌物种的首次报道。
