Gymnadenia conopsea Raw sequence reads

Symbiotic seed germination plays a vital role in orchid conservation, yet the molecular mechanisms governing early-stage host-fungal interactions remain largely unexplored. This study employs transcriptomic profiling of Gymnadenia conopsea during the initial symbiotic germination phase to characterize dynamic gene expression patterns and elucidate interaction mechanisms between the orchid host and its associated mycorrhizal fungi. By resolving spatiotemporal transcriptional reprogramming during this critical developmental window, the project aims to identify key signaling molecules and regulatory networks underlying symbiotic establishment. The generated data will address fundamental knowledge gaps in orchid-fungal mutualism while providing potential molecular targets for improving artificial propagation strategies in endangered orchid species.

共生种子萌发在兰科植物保育中具有至关重要的作用，但调控宿主与真菌早期互作的分子机制仍未得到充分阐明。本研究针对共生萌发初期的手参（Gymnadenia conopsea）开展转录组分析，以刻画其动态基因表达模式，并阐明兰科宿主与其共生菌根真菌之间的互作机制。通过解析该关键发育窗口期内的时空转录重编程过程，本项目旨在明确共生建立过程中的关键信号分子与调控网络。本研究产生的数据集将填补兰科-真菌共生关系中的基础认知空白，同时为濒危兰科物种优化人工繁育策略提供潜在的分子靶标。
