The genomic DNA PCR indicated that the genetic homogeneity between NIL-PL01 and NIL-APL01 reached 98.6%, which were being used in screening the molecular marker linked to apetalous trait.
利用随机引物对基因组DNA扩增结果表明，NIL -PL0 1和NIL -APL0 1之间多态性差异较小，遗传同质性达98.6 % ，该材料正用于筛选与无花瓣性状紧密连锁的分子标记。
Scientists have identified the first biochemical marker linked to sleep loss, an enzyme in saliva known as amylase, which increases in activity when sleep deprivation is prolonged.
经研究发现首个与失眠有关的生化标记。该标记是唾液中的一种酶，学名淀粉酶。当延长睡眠剥夺时间时，这种淀粉酶的活性就会随之增高。
