The reseach on activity changes of SOD, POD and CAT during the somatic embryogenesis of Y35 showed:(1) The activty of SOD was from 52.98 to 133.20 U·g-1·h-1, and remained a rising trend after early single embryo forming, this revealed that SOD might be positively correlated to the differentiation of embryogenic cell and the development of somatic embryo.(2) The activty of POD was from 0.05 to 0.50 U·mg-1·min-1, ascended firstly and desceded later, and was highest in embryogenic callus and lowest in late single embryo , this revealed that POD might be positively correlated to the division and differentiation of proembryo mass, while negatively correlated to the development of PEMⅢto late single embryo.(3) The activty of CAT was from 0.86 to 2.81 U·mg-1·min-1, showed an up-down-up trend, reaching to the highest peak at the time of early embryo formating and decreasing to the lowest at the time of early cotyledonary embryo formating, this revealed that CAT might be positively correlated to the development of early single embryo, while negatively correlated to the formation of middle single embryo and early cotyledonary embryo.The changes in activty of SOD, POD and CAT indicated these three antioxidant enzymes coregulated the differentiation and development of embryogenic cells during Larix somatic embryogenesis.4. Differentially expressed cDNA libraries of the stages of proembryo mass and somatic embryo maturation were successfully constructed by suppression subtractive hybridization.

对Y35体细胞胚胎发生过程中抗氧化酶活性变化的研究显示：(1)SOD活性在52.98~133.20 U·g-1·h-1之间，并在早期单胚形成后一直保持上升的趋势，表明其与胚性细胞的分化及体细胞胚的发育均具呈正相关；(2)POD活性在0.05~0.50 U·mg-1·min-1之间，呈现出先下降后升高的趋势，在胚性愈伤组织中最高，而在后期单胚形成时降至最低，表明其与原胚团的分裂和分化呈正相关，但与PEMⅢ向后期单胚的发育呈负相关；(3)CAT活性在0.86~2.81 U·mg-1·min-1之间，表现出升-降-升的变化趋势，在早期单胚形成时升至最高，在早期子叶胚形成时降至最低，表明其与早期单胚的发育呈正相关，而与中期单胚和早期子叶胚的发育呈负相关。

Psychrophilic and psychro-tolerant bacteria were cultured and used for screening the cold-active enzymes. Some characteristics of cold-active protease and chitinase were analyzed then. Microbial 16S rDNA clone libraries of deep sea sediments were constructed and studied by PCR-RFLP (Restriction Fragment Length Polymorphism) and phylogenetic analysis based on 16S rDNA sequences.
