Core Viewpoint - The article highlights the significant achievement of the Chenshan Center in Shanghai, which has surpassed a total of 100 million seeds in its collection, emphasizing the importance of preserving wild plant genetic resources for future biodiversity and research [2][3]. Group 1: Seed Collection and Preservation - The Chenshan Center has collected seeds from 1,950 species across 159 families and 785 genera, including 323 endemic species and 68 rare and endangered plants [2]. - The center's achievement of 100 million seeds is seen as a milestone, indicating its capability to maintain a large genetic information repository for future species restoration and research [2][3]. - The construction of the seed bank is a response to the increasing global biodiversity crisis, providing a backup for future ecological needs [3]. Group 2: Research and Scientific Contributions - The seeds collected are crucial for scientific research, contributing to breakthroughs in areas such as cancer drug discovery and the development of stress-resistant plant varieties [3]. - The seeds undergo a meticulous process of cleaning, drying, counting, and vitality testing before being stored in a cold environment at -20 degrees Celsius, which can extend their lifespan for decades [6]. - The Chenshan Center collaborates with other institutions, such as the Kunming Wild Biological Germplasm Resource Bank, to ensure the preservation and backup of these genetic resources [6]. Group 3: Educational and Public Engagement - The Chenshan Center hosted a seed exhibition called "Hundred Wind Travels," showcasing over 200 wind-dispersed seed species, including rare and endangered ones, to engage the public and inspire interest in science [8]. - The center's genetic resources are made available to numerous research institutions annually, facilitating studies in plant systematics, geography, and conservation experiments [9]. - The center's efforts in ecological restoration and urban biodiversity initiatives demonstrate the practical applications of its preserved genetic resources [9].
