At a glance of the molecular mechanism, one gene encoding 218 amino acids was identified from cDNA-AFLP differential study and then named as Ipomoea batatas MADS-box 1 gene (IbMADS1) based on earlier studies. From sequence alignment and phylogenic analysis, IbMADS1 exhibited a typical type II-MIKC structure, including two conserve domains, MADS-box and K-box.

本论文针对从甘薯块根筛选出的MADS-box基因，IbMADS1（Ipomoea batatas MADS-box gene 1）进行分析，分别探讨该基因在甘薯各部位的表现方式、受植物荷尔蒙调节的影响，以及甘薯属中野生亲缘种间的基因表现歧异性，再进一步从转殖植物的外表形态了解此基因可能的生理功能。

The study recruited 104 volunteers aged over 35 years old. 84 subjects without diseases of liver, kidney, heart, diabetes mellitus, stroke, mental disturbance gastro-intestine and pregnancy or breasting were screened by biochemical analyses.

本研究招募104位35岁以上的志愿受试者，依生化血液分析筛选出84位无肝、肾、心脏病、未控制之糖尿病者、怀孕或哺乳、最近一年中风者、精神方面疾病及肠胃道方面的疾病志愿者。

The screening was carried out by single strand conformational polymorphorsim : the PCR product precipitation was dissolved in 20μl denaturing and loading buffer (95%+20mMEDTA+ 0.05% bromophenol blue+0.05% xylene cyanol), heat-denatured in 95 ℃ to two single DNA strands.

通过单链构象多态性分析筛查RDS基因突变；沉淀回收的PCR产物以20μl变性上样液（95%甲酰胺+20mMEDTA+0.05%溴酚蓝+0.05%二甲苯蓝）溶解后热变性为两条DNA单链后，上样于8%非变性聚丙烯酰胺凝胶（含5%甘油），700伏电压、4℃电泳16小时。
