Science China Life Sciences 2025年第1期 309-310页

作者： Tao zhou Lin Li National Key Laboratory of Crop Genetic Improvement Huazhong Agricultural University HuBei HongShan Laboratory

The dual challenges of global climate change and population growth have increased demand for higher crop yields per unit area. The innovative technology of smart agriculture aims to synergize breeding, cultivation, and production through the application of biological and informatics technologies. Historically, the “Green Revolution” introduced semidwarf varieties of certain key crops by utilizing mutations affecting gibberellin pathways, which significantly increased planting densities and yields.

监察从宽处罚建议是监察机关在职务犯罪案件调查过程中享有的一项职权,该项制度对于落实宽严相济的刑事政策以及提高职务犯罪案件调查效果具有重要意义。《中华人民共和国监察法》《中华人民共和国监察法实施条例》对监察从宽处罚建议制度的适用条件和程序进行了明确规定,监察实践中该项制度的适用也取得了较好的效果。但是结合规范与实践分析,监察从宽处罚建议适用制度仍然存在着适用条件模糊、适用效力不清以及适用比例不均衡等现象,为此应当在厘清监察从宽处罚建议性质的基础上,有针对性地对该项制度进行完善,以发挥其在职务犯罪案件处理中的作用。
