在重金属污染土壤中加入磷酸盐是稳定重金属的有效方法.本研究的目的是探讨不同阴离子对水溶性磷酸盐稳定污染土壤铅、镉和锌的影响.在重金属复合污染土壤（全铅、镉和锌的含量分别为2337、21.4和391 mg·kg-1）中按P∶Pb=2∶1（mol∶mol）加入磷酸二氢钙,之后按P∶阴离子=3∶1或3∶2（mol∶mol）加入盐酸、氯化钠、硫酸、硫酸钠或氟化钠,并设置只加磷酸盐、不加其它试剂的对照,培养55 d,之后测定土壤性质.结果表明,与对照相比,hCl处理、2hCl处理、NaCl处理和2NaCl处理土壤DTPA-Pb含量下降比例依次为5.72%、9.29%、6.38%和8.80%（p〈0.05）,加入硫酸、硫酸钠的处理土壤DTPA-Pb含量与对照无显著差异（p〉0.05）,而加入氟化钠的处理升高4.70%（p〈0.05）.加入盐酸或氯化钠的处理土壤镉有效性显著高于对照（升高5.24%~12.8%）（p〈0.05）,其它处理对DTPA-Cd含量无显著影响（p〉0.05）.各处理对土壤DTPA-Zn含量和ph影响较小,但均引起土壤电导率明显升高.以上结果表明,氯离子可促进水溶性磷酸盐对土壤铅的稳定,但可促进镉有效性.氯磷酸铅的生成是加氯情况下磷酸盐稳定铅的重要机制.

The genetic link between apple red flesh(RF)coloration and the internal flesh browning disorder(FBD)is a major challenge when breeding high fruit quality RF apple cultivars.A genome-wide association study(GWAS)was conducted in a population of about 900 red-leaved seedlings to identify genomic regions and putative candidate genes using whole genome sequencing of the pools of extreme phenotypes(XP)for the RF colour coverage(using the weighted cortex index(WCI))and *** study identified novel genomic regions contributing to WCI and FBD variation in the red-leaved *** FBD-associated regions were enriched for genes regulating senescence,heat shock proteins,cytochrome P450,ascorbate metabolism and pectin methyl *** there were no significant regions in common for WCI and FBD,there were several genes(***85,MYB66,ethylene insensitive 3,DNAJ heat shock protein,WRKY7,and NAC42)enriched commonly between the genomic regions associated with these traits,potentially underpinning the genetic connection between WCI and *** of the differentially expressed genes between the R6:MdMYB10 and white-fleshed‘control’apples resided within the GWAS hotspot for WCI(*** synthase,UDP-Glycosyl transferase)and FBD(*** GTPase activating protein,lipoxygenase 1,phytoene synthase)–validating the XP-GWAS *** of several genes resided in the trait-associated genomic regions,suggesting that whole genome duplication plays an important role in the regulation of these *** genetic correlations between WCI and sensory traits were observed,and strategies to develop FBD-free high fruit quality RF cultivars are discussed.

提出一种无废烟气脱硫新方法。用硫化钠溶液洗脱工业烟气中二氧化硫，同时生成硫化氢。后者用Ｃｌａｕｓ反应可制取元素硫。反应过程为三阶段模式。第一阶段发生二氧化硫溶解和硫离子向硫氢根离子转变；第二阶段主要发生硫氢根离子向硫化氢转变同时吸收二氧化硫；第三阶段，溶液逐渐失去脱除ＳＯ２的能力。提高硫化钠初始浓度和反应温度或降低进气中二氧化硫含量，于提高Ｈ２Ｓ转化率有利。进气中二氧化硫分压增大，各阶段周期缩短。

Glioblastoma （GBM） is the most common and most aggressive primary brain tumor in adults. The existence of a small population of stem-like tumor cells that efficiently propagate tumors and resist cytotoxic therapy is one proposed mechanism leading to the resilient behavior of tumor cells and poor prognosis. In this study, we performed an in-depth analysis of the DNA methylation landscape in GBM- derived cancer stem ceils （GSCs）. Parallel comparisons of primary tumors and GSC lines derived from these tumors with normal controls （a neural stem cell （NSC） line and normal brain tissue） identified groups of hyper- and hypomethylated genes that display a trend of either increasing or decreasing methylation levels in the order of controls, primary GBMs, and their counterpart GSC lines, respectively. Interestingly, concurrent promoter hypermethylation and gene body hypomethylation were observed in a subset of genes including MGMT, AJAP1 and PTPRN2. These unique DNA methylation signatures were also found in primary GBM-derived xenograft tumors indicating that they are not tissue culture-related epigenetic changes. Integration of GSC-specific epigenetic signatures with gene expression analysis further identified candidate tumor suppressor genes that are frequently down-regulated in GBMs such as SPINT2, NEFM and PENK. Forced re-expression of SPINT2 reduced glioma cell proliferative capacity, anchorage independent growth, cell motility, and tumor sphere formation in vitro. The results from this study demonstrate that GSCs possess unique epigenetic signatures that may play important roles in the pathogenesis of GBM.

Taxonomic placement of genera have been changing rapidly as taxonomists widely use DNA sequence data in phylogenetic and evolutionary studies. It is essential to update existing databases/outlines based on recent studies, since thesesources are widely used as a foundation for other research. In this outline, we merge both asexual and sexual genera intoone outline. The phylum Ascomycota comprises of three subphyla viz. Pezizomycotina (including 13 classes, 124 ordersand 507 families), Saccharomycotina (including one class, one order and 13 families) and Taphrinomycotina (five classes,five orders and six families). Approximately, 6600 genera have been listed under different taxonomic ranks includingauxiliary (intermediate) taxonomic ranks.
