The antisense Caffeoyl CoA O methyltransferase (CCoAOMT) cDNA was transformed into chinese white poplar ( Populus tomentosa ) mediated by Agrobacterium tumefaciens . Many factors affecting the transformation efficiency were studied and a stable transformation system was established. PCR Southern blot analysis indicated that antisense CCoAOMT cDNA had been integrated into the genome of the transgenic poplars. RT PCR and Western blot analyses demonstrated that the endogenous CCoAOMT gene was suppressed at both transcriptional and translational levels. Klason lignin content assay exhibited the lignin reduction to different degrees in transgenic poplars. The stems of partial transgenic poplars with the remarkable lignin reduction turned red, and the color distribution was stripped or spotted. Taken together, these results suggested that CCoAOMT gene would be a potential useful gene in altering lignin biosynthesis by biotechnology for improving wood properties.

＜正＞Purpose To establish an efficient and stable gene delivery system based on recombinant adeno-associated viral vectors for retina research,such as dendrite development patterns of mouse retinal cells,especially retinal ganglion cells, and how the cell fate of various retinal cells is *** A bicistronic plasmid vector,pSIEWB,was acquired by molecular manufacture with elements derived from pSEWB which contains AAV genome and provides main structure of the vector and pCAGGS which provides the fragment containing IRES and EGFP *** of recombinant AAV vector was performed by a dual-vector,calcium phosphate-mediated transfection approach with pSIEWB and pD1rs which provides the AAV coat protein genes and helper virus genes necessary for packaging of recombinant AAV vector. Results The bicistronic plasmid vector,pSIEWB,has been acquired via replacing EGFP gene of pSEWB by fragment containing IRES-EGFP sequence derived from pCAGGS and it possesses the genome of recombinant AAV including two inverted terminal repeat elements（ITRs） which are necessary for viral packaging,human synapsin 1 promoter（hSyn 1） which can drive gene expression in neuron specially,IRES which can make functional gene and reporter gene express individually,EGFP which is a popular reporter gene to localize gene expression of vector,and woodchuck hepatitis post-transcriptional regulatory element（WPRE） which can optimize gene expression in *** the same time,an dual- vector, calcium phosphate-mediated transfection approach for viral packaging has been performed efficiently and stably in our lab,which needs two plasmids,pSIEWB and pD1rs which works as a helper plasmid for viral packaging because it contains AAV coat protein genes and adenovirus genes necessary for *** This study has provided a primary form of a gene delivery system for retina *** study on the process of dendrite development of retinal ganglion cells and cell fate determinatio

Modeling of Accent Perception in chinese Spontaneous Speech

Modeling of Accent Perception in Chinese Spontaneous Speech

引用

第六届全国现代语音学学术会议

作者： Tao Jianhua National Laboratory of Pattern Recognition Institute of Automation,chinese academy of sciences,{3.,China,100080

The accent was proved to be the essential links between linguistics and acoustics, and behaves as an important parameter for prosody processing and unit selection in speech synthesis system. In the paper, some acoustical measurements are carried out on FO, duration, silence in order to disclose the relationship between accent and corresponding acoustical parameters. The normalized acoustic parameters are induced to facilitate the accent detecting. Based on this, a model is proposed to predict accent in spontaneous speech. The method is proved to be very successful and has been used to label accent automatically for our large corpus. Further listening tests also show that the labelling results reaches 86% accurate rate, which is nearly the same as the agreement of hand labelling results. Furthermore, different native’s evaluations are also compared in the paper.
