The result showed that twocDNA fragments which expressed at high level both in shoot and radicle representedthe gene encoding beta-D-glucosidase; one cDNA fragment expressed specifically inshoot represented the gene encoding mitochondria HSP60; most clones of MF12 andMF17 fragments respectively represented the chloroplast genes encoding prp22 andprp19 proteins which are two components of ribosomal small subunit; while thededuced amino acid sequence from each exceptional one clone was respectivelyhomologous to CDC5 proteins and vesicle-associated membrane proteins; otherthree cDNA fragments expressed preferentially in shoot had no homologue inGenBank.

结果发现2个在胚芽和胚根中表达量都很高的cDNA片段代表的是编码玉米β-D-葡糖苷酶的基因；一个在胚芽中表达而在胚根中不表达的片段代表的是编码线粒体分子伴侣HSP60的基因；片段MFl2的大部分克隆测序结果是与叶绿体基因组中编码核糖体小亚基蛋白prp22的基因同源，但其中有一个克隆测定的cDNA片段序列推测的氨基酸序列与CDC5家族成员有较高的同源性；片段MF17的大部分克隆测序结果与叶绿体基因组中编码核糖体蛋白prp19的基因同源，而有一克隆测定的cDNA片段序列推测的氨基酸序列与参与信号转导的膜结合蛋白VAP27和VAMP有较高的同源性；另有3个优先在胚芽中表达的cDNA片段未查询到同源序列。
