单个体细胞这样发育成完整植株（探一线）

Core Insights - The research led by Shandong Agricultural University reveals the complete process of how a single plant cell can be reprogrammed to develop into a complete plant, addressing a long-standing question in plant life sciences [2][3] Group 1: Research Findings - The study identifies that plant cells possess a unique regenerative ability, allowing them to develop into embryos without fertilization, a phenomenon known as "somatic embryogenesis" [2] - The research team discovered that the accumulation of auxin is the "switch" that activates the totipotency of plant cells, enabling them to revert to a stem cell state [3] - Key genes involved in this process include SPCH, a gene specific to leaf pore precursor cells, and LEC2, which together form a "molecular switch" that triggers the totipotency [3][4] Group 2: Implications for Agriculture - The findings provide new insights into the fundamental rules of plant cell development and offer innovative approaches for precise regulation of plant regeneration and targeted improvement of crop traits [4] - Ongoing experiments are being conducted on crops such as wheat, corn, and soybeans, with the potential to rapidly clone superior crop varieties and significantly shorten breeding cycles [4] - This research could enhance the efficient conservation of rare plant genetic resources and inject new momentum into plant synthetic biology [4]
