Peroxisome proliferator-activated receptor g（PPARg） is an important regulator of chicken preadipocyte proliferation and *** this study,polymorphisms were detected by DNA sequencing,PCR-RFLP and some other methods and three polymorphisms（g.-1784_-1768del17,c.-1241GA and c.-75GA） were found in the 5＇ flanking region of PPARg *** and body composition traits were measured in the 8th-10th generation populations of the Northeast Agricultural University broiler lines were divergently selected for abdominal fat *** among individuals were screened in the above *** haplotype-based association analysis on growth and body composition traits was carried *** association analysis showed that haplotypes based on three polymorphisms at 5＇ flanking region of PPARg gene were significantly associated with abdominal fat weight（AFW）,abdominal fat percentage（AFP,AFW/BW7）,liver weight（LW）,liver weight percentage（LFP,LW/BW7）,shank length（ShL）,femur weight（FeW）,keel length（KeL）,and metatarsus circle（MeC）（P0.05） and suggestive significantly associated with pectoralis major weight（PMaW）,pectoralis minor weight（PMiW）,pectoralis minor weight percentage（PMiWP,PMiW/BW7）,and metatarsus length（MeL）（P0.2）.The least square analysis showed that the birds with BGA haplotype had significantly higher AFW and AFP than the birds with other haplotypes（P0.05）.The birds with AAG haplotype had significantly higher LW and LW/BW than the birds with other haplotypes（P0.05）.The birds with AAG haplotype had significantly higher PMiW and PMiW/BW than the birds with other haplotypes（P0.05）.The birds with AAG haplotype had significantly higher ShL,FeW,MeL,MeC and KeL than the birds with AGG haplotypes（P0.05）.The results in this study revealed that QTL affecting fatness traits may exist in 5＇ flanking region of PPARg gene in chickens and PPARg gene might be one of the genes having important influences on the growth and bone traits in chickens.

Ablotlc stress, such as salt, drought and extreme temperature, can result in enhanced production of reactive oxygen species （ROS）. Plants have developed both enzymatic ROS-scavenging and non-enzymatic ROS-scavenging systems. The major ROS-scavenging enzymes of plants include superoxide dismutase （SOD）, ascorbate peroxldaae （APX）, catalaae （CAT）, glutathione peroxldaae （GPX） and peroxiredoxina （Prxa）. In the present work, we identified a gene encoding chloroplast-located peroxiredoxin Q, SsPrxQ, from Suaeda salsa L. located at chloroplast. Overexpression of SsPrxQ In Arabidopsis leads to an increase In salt and low-temperature tolerance.

A novel J-domain protein gene was cloned from wheat （Triticum aestivum L.） using RT-PCR technology and named as TaJ. The J-domain protein is defined by the presence of a J-domain. The cDNA of T. aestivum gene, TaJ （GenBank accession number： DQ789026）, was 1263 bp and contained a complete open reading frame （ORF） encoding a J-domain protein of 420 amino acid residues. The predicted amino acid sequence of TaJ possesses three functionally essential domains： the Nterminal J-domain which includes the highly conserved HPD tripeptide, an adjacent domain that is rich in glycine and phenylalanine residues （G/F） and a Cysteine-rich zinc-finger domain with four repeats of CxxCxGxG that is important for protein interactions. The C-terminal of TaJ was -CAQQ, a farnesylation motif. The full-length deduced amino acid sequence of TaJ is highly homologous to J-domain proteins from various plant species. Southern blot analysis indicated that a single copy of TaJ existed in wheat genome. The expression pattern of TaJ performed by real-time PCR demonstrated that heat shock （HS） at 37℃ induced the expression of TaJ rapidly and strongly, but the response of the TaJ gene to cold stress was much slower than that to HS. Tissue-specific expression analysis showed that the expression level of TaJ gene was much higher in leaves than that in roots.

As digital cameras continue to replace their analog counterparts, the importance of authenticating digital images,identifying their sources,and detecting forgeries is *** image forensies is used to analyze an image in the complete absence of any digital watermark or *** compositing is the most common form of digital *** that image compositing operations affect the inherent statistics of the image,we propose an image compositing detection method on based on a statistical model for natural image in the wavelet transform *** generalized Gaussian model(GGD)is employed to describe the marginal distribution of wavelet coefficients of images,and the parameters of GGD are obtained using maximum likelihood *** statistical features include GGD parameters,prediction error,mean,variance,skewness,and kurtosis at each wavelet detail ***,these feature vectors are used to discriminate between natural images and composite images using support vector machine(SVM).To evaluate the performance of our proposed method,we carried out tests on the Columbia Uncompressed Image Splicing Detection Dataset and another advanced dataset,and achieved a detection accuracy of 92% and 79%.*** detection performance of our method is better than that of the method using cameraresponse function on the same dataset.

由于数据流的流动性与连续性,数据流所蕴含的知识会随着时间的推移而发生变化.因此,在绝大多数数据流的应用中,用户往往对新产生的流数据所包含的知识要比对历史流数据所包含的知识感兴趣得多.提出了一种挖掘数据流任意大小滑动时间窗口内频繁模式的方法MSW(mining sliding window).当数据流流过时,该方法使用滑动窗口树SW-tree在单遍扫描流数据的条件下及时捕获数据流上最新的模式信息.同时,该方法还周期性地删除滑动窗口树上过期的及不频繁的模式分支,从而降低滑动窗口树的空间复杂度与维护代价.此外,该方法还应用时间衰减模型逐步降低历史事务模式支持数的权重,并由此来区分最近产生事务与历史事务的模式.大量仿真实验的结果表明,算法MSS具有较高的效率与优良的可扩展性,同时也优于其他同类算法.
