The present study provides an insight on physiological parameters and root-associated microbiome of two complementary Arabidopsis thaliana culture systems suitable for physiological studies. Methods: A. thaliana plants were grown in rhizobox and in classic pot culture. An analysis of plant growth parameters along with the characterization of the bacterial communities of the compost and the rhizosphere, rhizoplane and endosphere compartments were performed. Results: A. thaliana plants grown in rhizobox exhibited a plant habitus similar to those grown in pots during the first month, but with a delayed leaf initiation and slower rate of growth over the experiment. No nutrient deficiency symptoms were observed in these plants. The rhizobox design permits the migration of bacteria from compost to plant roots and allowed root-bacteria interactions to be established as in traditional pot culture. Some differences into the composition of the rhizobiome were highlighted between the two culture systems. Nevertheless, key bacterial taxa that help to ensure plant growth and health colonized the rhizo- and endosphere compartments in both systems. Conclusions: This study gives some clues for future research programs and selection of efficient root systems with the use of such specific culture devices.

从根微生物组的角度评估拟南芥在根箱培养系统中的生长

本研究提供了对适合生理研究的两种互补拟南芥培养系统的生理参数和根相关微生物组的见解。方法：拟南芥植物在根箱和经典盆栽中生长。进行了植物生长参数的分析以及堆肥和根际、根面和内层隔室的细菌群落的特征。结果：在根箱中生长的拟南芥植株在第一个月表现出与盆栽相似的植物习性，但在实验中叶发育延迟且生长速度较慢。在这些植物中没有观察到营养缺乏症状。根箱设计允许细菌从堆肥迁移到植物根部，并允许在传统盆栽培养中建立根-细菌相互作用。两种培养系统之间强调了根际生物群落组成的一些差异。尽管如此，有助于确保植物生长和健康的关键细菌分类群在两个系统的根际和内层隔室中定殖。结论：本研究为未来的研究计划和使用此类特定培养设备选择有效的根系提供了一些线索。有助于确保植物生长和健康的关键细菌分类群在两个系统的根际和内圈隔室中定殖。结论：本研究为未来的研究计划和使用此类特定培养设备选择有效的根系提供了一些线索。有助于确保植物生长和健康的关键细菌分类群定居在两个系统的根际和内圈隔室中。结论：本研究为未来的研究计划和使用此类特定培养设备选择有效的根系提供了一些线索。
