Dear Editor,Bread wheat(Triticum aestivum L.) is a globally important cereal providing ～20%of the calories and proteins for >4.5billion people. Plant architecture, including morphologies of leaves, spikes, stems,and roots, has great impact on plant development and productivity, and thus has been extensively investigated in various plant species(Jiang et al., 2023;Zhang et al., 2017).

为合成具有期望性能的表面活性剂需采用不同的合成策略。讨论了可生物降解和环境友好的表面活性剂的几种性价比高、步骤少的有效合成方法。这些方法采用经济的资源如单糖、松香酸、脂肪酸等为起始原料,其成本主要来自于溶剂和特定试剂的使用。天然产物尽管很多,但只有少数适合被转换为表面活性剂。由于不存在很好的通用表面活性剂,还讨论了不同表面活性剂的制备。
