INTRODUCTION
This study is the first to investigate the genetic diversity of plant growth-promoting genes in rhizobacteria isolated from the wild ecology of Mount Erciyes, Türkiye. It has a flora rich in flowering plants, with 1170 plant taxa, 194 of which are endemic to the area.
METHODS
A total of 165 bacterial isolates, including sp., sp., and sp., were screened for genes associated with plant growth promotion: nitrogen fixation (), indole pyruvate decarboxylase (), 1-aminocyclopropane-1-carboxylate deaminase (), phosphate-solubilizing genes (, and ), and siderophore biosynthesis ().
RESULTS
The analysis revealed significant genetic variability across isolates, particularly for and genes, with distinct band patterns indicating genetic diversity among and isolates.
DISCUSSION
The findings emphasize the role of these rhizobacteria in nutrient cycling and stress resilience, potentially enhancing plant growth in nutrient-limited soils. In the current study, it contributes to understanding microbial biodiversity in Mount Erciyes and suggests a promising potential for sustainable agriculture through plant-microbe interactions.
引言
本研究首次调查了从土耳其埃尔西耶斯山野生生态环境中分离出的根际细菌中促进植物生长基因的遗传多样性。该地区植物区系丰富，有1170种植物分类群，其中194种为该地区特有。
方法
共筛选了165株细菌分离株，包括 种、 种和 种，检测与植物生长促进相关的基因：固氮（ ）、吲哚丙酮酸脱羧酶（ ）、1-氨基环丙烷-1-羧酸脱氨酶（ ）、解磷基因（ 、 和 ）以及铁载体生物合成（ ）。
结果
分析显示各分离株之间存在显著的遗传变异性，特别是对于 和 基因，不同的条带模式表明 和 分离株之间存在遗传多样性。
讨论
研究结果强调了这些根际细菌在养分循环和抗逆性中的作用，可能会促进养分有限土壤中的植物生长。在当前研究中，有助于了解埃尔西耶斯山的微生物多样性，并通过植物-微生物相互作用为可持续农业展现出了有前景的潜力。
