不同食料对野生蚕蛹营养成份的影响

随机选取采食七种树叶的野生蚕蛹,分别测定粗蛋白,脂肪和氨基酸,结果发现:蚕蛹的粗蛋白、脂肪,十七种氨基酸随采食的树叶不同其含量也有差异,这一结果提示我们:不同食料对野生蚕蛹的蛋白质,脂肪和氨基酸的含量有明显的影响,通过不同的食料,可以改变野生蚕蛹中主要营养成份的含量。

Efficient indica and japonica rice identification based on the InDel molecular method: Its implication in rice breeding and evolutionary research

An efficient molecular method for the accurate and efficient identification of indica and japonica rice was created based on the poly-morphisms of insertion/deletion (InDel) DNA fragments obtained from the basic local alignment search tool (BLAST) to the entire genomic sequences of indica (93-11) and japonica rice (Nipponbare). The 45 InDel loci were validated experimentally by the polymerase chain reaction (PCR) and polyacrylamide gel electrophoresis (PAGE) in 44 typical indica and japonica rice varieties, including 93-11 and Nipponbare. A neutrality test of the data matrix generated from electrophoretic banding patterns of various InDel loci indicated that 34 InDel loci were strongly associated with the differentiation of indica and japonica rice. More extensive analyses involving cultivated rice varieties from 11 Asian countries, and 12 wild Oryza species with various origins confirmed that indica and japonica characteristics could accurately be determined via calculating the average frequency of indica- or japonica-specific alleles on different InDel loci across the rice genome. This method was named as the "InDel molecular index" that combines molecular and statistical methods in determining the indica and japonica characteristics of rice varieties. Compared with the traditional methods based essentially on morphology, the InDel molecular index provides a very accurate, rapid, simple, and efficient method for identifying indica and japonica rice. In addition, the InDel index can be used to determine indica or japonica characteristics of wild Oryza species, which largely extends the utility of this method. The InDel molecular index provides a new tool for the effective selection of appropriate indica or japonica rice germplasm in rice breeding. It also offers a novel model for the study of the origin, evolution, and genetic differentiation of indica and japonica rice adapted to various environmental changes.

中国三北地区部分野生小鼠形态分类学分析

对中国并部地区１０个捕鼠地捕获的野生小鼠（鼷鼠）进行了分类学分析和形态特征调查,主要对３００只野生小鼠和３０只实验品系小鼠的体重、头体长、尾长、后脚长及耳长等体征进行了测量和形态特征描述。同时应用统计学分析了不同区域野生小鼠之间、相同捕鼠地雌雄野生小鼠之间及野生小鼠与实验近交系小鼠之间形态特征差异,这些实量指标和形态学特征可望成为识别不同地区野生小鼠资源的重要标志。
