The expression profiles analysis of 25 genes belonging to 8 types in different development periods of Y35 somatic embry showed, genes involved in transcription, signal transduction, cell fate, substance transport, cell and development regulation were active at early and middle stages of somatic embryogenesis, while at the stage of cotyledonary embryo maturation, the high level-expressed genes were mainly those related to storage protein, maturation and defense.

通过半定量和Real-Time PCR技术，对WRKY和MAPKK等8类25个差异表达基因在Y35体细胞胚不同发育时期的表达分析显示，转录、信号转导、细胞生长分裂、细胞命运、物质转运和多数发育调节相关基因在体细胞胚胎发生的早期或中期比较活跃，而进入子叶胚成熟后期则主要是储藏蛋白、成熟和防御相关基因大量表达。

There were 2 peaks of starch accumulation in the process of somatic embryogenesis,the first time was at the stage of embryogenic callus,the second time was at the stage of globular embryoids;and a small raise appeared at the stage of torpedo-shaped embryoids,and the content of starch was slightly higher than those of heart-shaped embryoids and cotyledonary embryoids.With the development of embryos,the tendency of the changes of the content of DNA,RNA and the total nucleic acids was approximately similar,and the peak values were all at the stage of cotyledonary embryoids,and the change of the content of RNA was more remarkable than those of DNA and the total nucleic acids.The tendency of change of the content of proteins almost took on the S-shaped curve.

结果表明：龙眼胚性愈伤组织体胚发生过程中淀粉有2个累积峰值，第1次出现在胚性愈伤组织阶段，第2次出现在球形胚阶段，在鱼雷形胚阶段又有一个小回升，这时淀粉积累较心形胚和子叶形胚阶段高一些；随着胚胎的发育，DNA、RNA、总核酸含量的变化趋势大致相同，最高点均出现在心形胚阶段，其中RNA含量的变化较DNA、总核酸含量明显，蛋白质含量的变化曲线呈&S&形。

During somatic embryogenesis, we were able to trace the FAC1 expression to single embryogenic cells, suggesting its critical role in early induction.

FACl在体细胞胚胎发育过程中的表达可以追踪到单个的胚性细胞，说明它在激活早期胚胎发育中的关键地位。

To study the molecular mechanism of Larix somatic embryogenesis, a differentially expressed cDNA library of Larix somatic embryo in the period of maturation was constructed using suppression subtractive hybridization. The cDNA from the cultures at the stage of somatic embryo maturation of embryogenic cell line Y35 of L. leptolepis ×L. principis-rupprechtii was used as the tester and the cDNA from its subcultured callus was used as the driver. Eight hundreds randomly selected positive clones were sequenced, and 468 UniGenes were obtained finally.
