大豆（Glycine max (L.) Merrill）起源于我国，是世界第一大植物蛋白质和第二大食用植物油脂来源，在国民经济发展和保障国家粮食安全中具有重要地位。值得注意的是，随着人民生活水平的提高，豆粕和豆油需求不断增加，大豆进口量连年增长，自给率仅为15%左右，已成为我国大豆在国际竞争中“卡脖子”的关键因素。然而，大豆作为中度盐敏感型作物，当土壤中盐碱度超过5 dS/m时，大豆产量即可降低5...

核糖体RNA（rRNA），在细胞增殖中起着不可替代的作用，与G-四链体rDNA一起，G-四链体rRNA也会参与到许多复杂的细胞调节过程。因此，设计能够区分这两类核苷酸二级结构的特异性的荧光探针具有重要的实际意义。粘度，作为扩散控制过程中一个最重要的因素，在生物活动中起着至关重要的作用。细胞微环境的粘度异常变化与许多人类疾病，如糖尿病、阿尔茨海默病、动脉粥样硬化等息息相关。综上所述，开发能够特异性识...
