Group 1 - A research team from the Northeast Institute of Geography and Agroecology of the Chinese Academy of Sciences and the Yazhou Bay National Laboratory has discovered a regulatory gene for "embryo-less" rice, which is expected to enhance the quality and storage capacity of rice [1] - The key regulatory gene OsBZR4 was cloned and its mechanism of action was elucidated, showing that mutations in this gene can produce 60% to 100% embryo-less seeds across different cultivated varieties [1] - The application of transgenic technology is crucial for food security, addressing climate crises, and achieving green agricultural transformation, with a projected 60% increase in global food demand by 2050 due to a population rise to 9.8 billion [1] Group 2 - The Central Document No. 1 emphasizes the industrialization of biological breeding, with policies such as financial subsidies, tax incentives, and market access facilitation to accelerate technology implementation [2] - Future efforts should focus on technological innovation (gene editing, composite traits), policy support (industrial promotion), and public trust (transparent regulation and science popularization) to transition China from a "seed power" to a "strong seed industry" [2] Group 3 - Companies such as Shennong Seed Industry and Beidahuang are mentioned in relation to the advancements in the seed industry [3]
