다국어 초록 (Multilingual Abstract)

Seed germination and root development are important indicators of plant development. Here, we propose a new nanotechnology to guide plant growth and development. We developed polymer-based soil model platforms with various nanotopographical features to explore the influence of guiding topographical cues on plant development including phenotypic aspects and gene regulation. The fabricated nanotextured surfaces showed the good mechanical stability, biocompatibility, strong adhesion, non-toxicity as well as super hydrophobicity. Our new Arabidopsis root system had the abundant molecular genetic resources according to the unique nano-structure designs, controlling the plant growth, which can be used as a new platform for investing the phenotype and gene networks. Finally, we showed some examples that our nanotopographical platforms could promote the plant growth and development by providing specific roadmap and transport genes responsible.
