科研新突破！中国科学家破解植物再生密码

Core Insights - The research focuses on how plants maintain stem cell function to achieve strong regenerative abilities, which is crucial for enhancing crop yields, improving fruit and vegetable quality, and increasing forest adaptability [3][4] - A recent study by a research team from the Chinese Academy of Sciences reveals that the mechanical properties of the cell wall play a central role in stem cell regulation, highlighting a unique "biphasic distribution" of pectin in the stem cell region of plant shoot tips [3] Group 1 - The study found that newly formed cell walls are "softer" and rich in demethylated pectin, while mature cell walls are "harder" and primarily consist of highly methylated pectin, which is essential for maintaining the homeostasis of the stem cell microenvironment [3] - The research results were published in the international academic journal "Science" on December 5 [3] Group 2 - This research, based on a "precise design of cell walls" strategy, is expected to enhance the activity of crop meristem tissues and yield potential, providing critical theoretical support and technical pathways for cultivating high-yield and efficient crops [4] - The findings are significant for promoting agricultural technological innovation and empowering future crop design and breeding, contributing to national food security and the achievement of carbon neutrality goals [4]
