苗期低温锻炼对水稻叶片生理性状的影响

通过苗期亚低温的锻炼,研究水稻品种的诱导抗性.实验结果表明,与抗冷性弱的二九丰相比,抗冷性强的中冷8号通过亚低温锻炼,在叶绿素含量、叶片质膜透性、可溶性糖含量三个指标上表现出更强的抗低温能力.说明不同抗冷性的水稻品种具有不同的诱导抗性.     

霍林河盆地煤层气储量及有利勘控区预测

针对霍林河盆地良好的地质特征,为发展煤层气资源预测分析.指出煤的镜质组反射率多在0.5%～0.6%之间,煤质含气量最高为7.7 m/t.煤质中煤层气含量以及煤层气中甲烷含量随深度加大而迅速增加.400 m以下为甲烷带,400m以上为甲烷-氮气带.并对含气量进行了预测,500m以下煤层气含量约3.0～7.7m3/t煤计,霍林河盆地煤层气远景储量在268.5×108～689.2×108m3之间.同时,指出了有利于煤层气形成和勘探的有利地段,9-73孔,21-11孔附近地区为最有利煤层气勘探区.

可持续发展的外语学习能力探析

综合哲学、教育学、心理学和二语习得等不同角度对学习能力的理解,对可持续发展的外语学习能力内涵进行阐释。外语学习能力系统既包括智力因素,也包括非智力因素。外语学习能力应由基本学习能力、拓展学习能力和调节学习能力三大要素构成,三大要素中又包含一系列子要素,其中语言学习的迁移能力、自主学习能力和持久动机是外语学习能力可持续发展的重要指标。

Pedigree transmission disequilibrium test for quantitative traits in farm animals

General pedigrees are very common in farm animals,and the recent availability of large panels of SNPs in domestic species has given new momentum to the search for the mutations underlying variation in quantitative traits.In this paper,we proposed a new transmission disequilibrium test approach,called the pedigree transmission disequilibrium test,which deals with general pedigrees and quantitative traits in farm animals.Compared with the existing pedigree disequilibrium test (PDT) and general linear model-based method QTDT,our approach performed better with higher power and lower type I error,especially in scenarios where the quantitative trait locus (QTL) effect was small.We also investigated the application of our approach in selective genotyping design.Our simulation studies indicated that it was plausible to implement a selective genotyping strategy in the proposed pedigree transmission disequilibrium test.We found that our approach performed equally well or better when only some proportion of the individuals in the two tails were genotyped compared with its performance when all the individuals in the pedigree were genotyped.     

小额诉讼程序与速裁程序的比较及立法选择

小额诉讼程序和速裁程序皆为我国民事诉讼简易化程序改革之产物,两者既有相同之处又有相异之点。从司法改革趋势来看,速裁程序日益凸显其实践价值,小额诉讼程序则逐渐式微。但是,不能因速裁程序之＂兴盛＂,小额诉讼程序之＂没落＂,而在倡举速裁程序之时,完全摒弃小额诉讼程序之功能性价值。毕竟,小额诉讼程序与速裁程序并无本质上的冲突和矛盾,两者均有值得引鉴的内在机制。所以,改进和整合小额诉讼程序和速裁程序,将小额诉讼程序置于速裁程序之中,成为速裁程序一部分更为合理。

Framework for dissection of complex cytonuclear epistasis by a two-dimensional genome scan

Epistasis between cytoplasmic and nuclear genes is the primary genetic component of complex quantitative traits.Genetic dissection of cytonuclear epistasis is fundamentally important to understand the genetic architecture of complex traits.In this study,a two-dimensional genome scan strategy was employed to evaluate the contribution of cytoplasm,quantitative trait loci (QTL),QTL×QTL interactions and QTL×QTL×cytoplasm interactions to the phenotypic variation.The p-value and parameter value for each genetic effect were calculated by multiple regression analysis.A stepwise approach was suggested to build confidence in candidate QTL on the basis of q-value estimation,false discovery rate calculation and Bonferroni adjustment.A fine-scale grid scan strategy was proposed for further analysis of peaks of interest.Plant height in maize was used as an example to illustrate the efficiency of the two-dimensional genome scan strategy.
