1·R is a replaceable function, e. G. Acetoxy, methoxy, their acyloxy and alkoxy homologs or halo.

是取化基，如乙氧基、甲氧基及它们的环氧和烷氧同系物或卤基。

2·MIR is not homologous to any known protein, as homologs were not found in the rice or Arabidopsis genome databases, or in the EST database for other organisms.

通过对拟南芥和水稻基因组的以及其他物种EST数据库的比对，发现MIR和已知蛋白均不同源。

3·A new chemical equation for the reaction of ethane with steam is suggested. It is pointed out that the steam conversion is similar to hydrocracking of methane homologs.

提出了乙烷与水蒸汽转化反应的新化学计量方程序，对已有的反应机理作了补充，指出甲烷同系物的水蒸汽转化与其加氢裂解反应的相似本质。

4·Database search revealed that homologs of CT120 existed in different organisms from plant to animal kingdoms, which suggested that CT120 was a highly conserved gene during biological evolution.

CT120的同源物广泛存在于从植物到动物界不同物种中，提示新基因CT120在生物进化过程中高度保守。

5·To examine whether rice ice homologs function in cold acclimation via regulation of rice DREB homologs in response to cold stress, we assessed a polypeptide epitope containing an ICE-specific motif.

为了检测在寒冷条件下，水稻ice同系物是否通过调节水稻DREB的同系物来对冷胁迫的作出反应，我们鉴定了一个含有ice特异基序多肽抗原决定基。
