Soil salinity is one of the major abiotic stresses affecting plant growth and crop *** the present study,salt tolerance at rice seedling stage was evaluated using 87 introgression lines（ILs）,which were derived from a cross between an elite indica cultivar Teqing and an accession of common wild rice（Oryza rufipogon Griff.）.Substantial variation was observed for four traits including salt tolerance score（STS）, relative root dry weight（RRW）,relative shoot dry weight（RSW） and relative total dry weight（RTW）.STS was significantly positively correlated with all other three traits.A total of 15 putative quantitative trait loci（QTLs） associated with these four traits were detected using single-point analysis,which were located on chromosomes 1,2,3.6,7,9 and 10 with 8%-26%explaining the phenotypic *** O. rufipogon-derived alleles at 13.QTLs（86.7%） could improve the salt tolerance in the Teqing *** QTL clusters affecting RRW, RSW and RTW were found on chromosomes 6,7,9 and 10,*** these four QTL clusters,a major cluster including three QTLs （qRRWIO,qRSWIO and qRTWIO） was found near the maker RM271 on the long arm of chromosome 10,and the ***-derived alleles at these three loci increased RRW,RSW and RTW with additive effects of 22.7%,17.3.and 18.5%,respectively,while the phenotypic variance explained by these three individual QTLs for the three traits varied from 19%to 26%.In addition,several salt tolerant ILs were selected and could be used for identifying and utilizing favorable salt tolerant genes from common wild rice and used in the salt tolerant rice breeding program.

Spt是一大类参与酿酒酵母转录调控的蛋白质。Spt蛋白是SAGA复合体的组成部分,该复合体与基因上游TATA框区域相互作用而发挥调控作用。根据目前的研究,约有10%的酿酒酵母基因转录受到Spt蛋白的调控,且与环境压力下上调基因的调控密切相关。Spt蛋白参与的庞大的调控网络及其复杂的调节机制是当前一个研究热点。Spt蛋白还具有转座子抑制的功能,是转座子功能调控和适应性进化意义上的重要"开关"。除此之外,一些Spt蛋白可以直接调控不饱和脂肪酸的合成,从而直接影响细胞膜重塑,对于酵母广泛抗性具有重要意义。文中从以上3.维度对迄今为止Spt蛋白的研究进展进行综述,结合前期研究工作,对于Spt蛋白通过转录调控、细胞膜转变、转座活性调节用以增强酿酒酵母抗性的潜在作用谨作展望。

china is rich in chicken genetic resources,; many indigenous breeds can be found throughout the country. Due to poor productive ability, some of them are threatened by the commercial varieties from domestic; foreign breeding companies. In a large-scale investigation into the current status of Chinese poultry genetic resources, 78 indigenous chicken breeds were surveyed; their blood samples collected. The genomes of these chickens were screened using microsatellite analysis. A total of 2740 individuals were genotyped for 27 microsatellite markers on 13.chromosomes. The number of alleles of the 27 markers ranged from 6 to 51 per locus with a mean of 18.74. Heterozygosity (H) values of the 78 chicken breeds were all more than 0.5. The average H value (0.622); polymorphism information content (PIC, 0.573. of these breeds suggested that the Chinese indigenous chickens possessed more genetic diversity than that reported in many other countries. The fixation coefficients of subpopulations within the total population (F ST) for the 27 loci varied from 0.065 (LEI0166) to 0.209 (MCW0078), with a mean of 0.106. For all detected microsatellite loci, only one (LEI0194) deviated from Hardy-Weinberg equilibrium (HWE) across all the populations. As genetic drift or non-random mating can occur in small populations, breeds kept on {3. farms such as Langshan chicken generally had lower H values, while those kept on large populations within {3. regions possessed higher polymorphisms. The high genetic diversity in Chinese indigenous breeds is in agreement with great phenotypic variation of these breeds. Using Nei’s genetic distance; the Neighbor-Joining method, the indigenous Chinese chickens were classified into six categories that were generally consistent with their geographic distributions. The molecular information of genetic diversity will play an important role in {3., supervision,; utilization of the chicken resources.

作者： Liu Jian Bureau of S & T for resources and Environment, Chinese Academy of Sciences, Beijing 100864, china

The topic was concentrated on environmental technology development in china within the context of china's economic acceleration and reform. Firstly, cleaner technology should be adopted where possible in industrial production; secondly, eco agricultural technological system, especially biological technology, should be developed in agricultural production; thirdly, end of pipe solution should focus on waste {3. or recycling technology where appropriate clean technology does not exist; lastly but not the least, existing technologies to minimize eco environmental deterioration such as soil erosion, salinization, desertification and deforestation should also be extended and developed. The mentioned ways of environmental technology development can only be realized on the condition that a resource {3. based production system and life style could be established and appropriate policy secured.

建立了太阳池热盐双扩散数值模型,模拟结果与实验值对比,吻合较好。讨论了提热过程对太阳池热盐特性的影响规律,在提热速率不破坏NCZ稳定性的前提下,随着提热量的增大,热损失和盐损失都减小。热损降低,太阳池热效率提高;而盐损失降低,则利于NCZ内盐梯度的保持。模拟了太阳池受池底热损影响的热盐扩散规律。Soret通量所占总通量的比值在提热量和池底热损较小的情况下最大超过10%,因此Soret效应引起的盐扩散对总盐扩散起着不可忽视的作用。
