Broodstock wintered at at 2~5℃ were fed Nitzschia closterium (30×10^4~50×10^4 cells/mL) supplemented with Chlorella sp. and egg yolk and had a mortality of 1.9%, 4.0% and 9.98% during maturation-inducing. However, the broodstock wintered at below 0℃ were fed the same food and had an increased mortality of 15.87%, 18.8%, 26.27% and 32.07% during maturation-inducing, indicating that there is influence of water temperature on survival of the broodstock during wintering period.

1当水温为2~5℃时，越冬的亲贝在促熟中是以新月菱形藻（30~50万个／mL）为主要饵料，辅以小球藻、蛋黄等，死亡率分别为1.9%，4.0%，9.98%；在0℃以下的越冬亲贝，在促熟中使用同样饵料，则死亡率提高为15.87%，18.0%，26.27%，32.07%，说明亲贝在海中越冬时，水温的高低直接影响亲贝在升温促熟饲育中的成活率。

The results indicate that:(1) For consuetudinary maturation culture mediums, such as M199 andα-MEM,the maturation rates of denuded oocytes are significantly lower than Cumulus-oocytecomplexs.

结果表明：(1)对于常规的成熟培养液M199、α-MEM而言，去除卵丘细胞的卵母细胞成熟率要极显著低于卵丘卵母细胞复合体。

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。

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.
