北京水系中腐霉和疫腐霉种类调查

为研究北京地区水系中腐霉和疫腐霉种类分布,采用叶饵法从北京水系中诱集菌株,共分离到腐霉、疫腐霉182株,利用Single-strand conformation polymorphism (SSCP)进行分析,筛选出不同基因型的代表菌株,并依据形态学特征及ITS序列对这些菌株进行种类鉴定。结果共发现6个已知种和3个可能的新种,其中:湖滨疫腐霉Phytopythium litorale和果胶裂解腐霉Pythium pectinolyticum为国内新记录种;旋柄疫腐霉Pp.helicoides、异丝腐霉P.diclinum、簇囊腐霉P.torulosum和袋囊腐霉P.marsipium为北京地区新记录种。研究结果可为未来监测北京地区水系中病原菌的分布情况提供基础数据。

上海城市绿地中景观灯配置对植物的影响

通过对上海主要绿地中景观灯与植物配置的调查分析,结果表明,悬挂造型灯的饰景照明、缠绕或覆盖灯串的轮廓照明以及运用泛光灯的泛光照明是景观灯与植物配置结合应用最广泛的形式;金属卤化物灯、高压钠灯和LED是目前上海植物造景中应用较多的景观灯类型;灯光颜色以黄、绿、红、蓝紫色系为主;景观灯的光照强度因光源类型及与植物的距离而存在差异,文章还分析了常见的景观灯配置形式对植物可能产生的影响。

低温胁迫下马铃薯的数字基因表达谱分析

以马铃薯品种合作88为材料,利用数字基因表达谱(DGE)技术,对–2℃低温胁迫处理后的马铃薯叶片c DNA文库进行差异基因表达谱分析。结果表明,有28 505个基因受低温胁迫诱导差异表达,其中上调表达基因13 703个,下调表达基因14 802个。GO功能显著性富集分析表明,DEGs主要涉及信号生物代谢过程、氧化还原过程、能量代谢、次生代谢过程以及催化活性。KEGG富集分析表明,上调表达基因主要富集于苯丙烷、光合作用天线蛋白、类胡萝卜素的生物合成、苯丙氨酸代谢及淀粉与蔗糖代谢途径,而下调表达基因主要富集于植物激素信号转导途径。利用实时荧光定量PCR(q RT-PCR)验证4个DEGs在低温胁迫条件下的差异表达,其结果与DGE分析结果基本一致,证实了DGE测序结果的可靠性。     

盐碱胁迫对紫花苜蓿和草木樨发芽及出苗的影响

为选择适宜在盐碱土上种植的牧草种类,合理开发和利用盐碱地资源,分别进行室内发芽和室外出苗试验,研究盐碱胁迫对紫花苜蓿和草木樨发芽及出苗的影响.结果表明,各个浓度模拟盐碱胁迫均对紫花苜蓿的发芽有抑制作用;50 mmol/L盐溶液和5 mmol/L碱溶液对草木樨发芽有促进作用,150～250 mmol/L盐溶液和5～25 mmol/L碱溶液其发芽有抑制作用.研究同时表明,紫花苜蓿适宜种植于极轻度盐化土壤和极轻～轻度碱化土壤(pH值为8～9,EC为0.2～0.7mS/cm);草木樨则适宜种植于轻度～重度盐化土壤和中度～重度碱化土壤(pH值为9～10,EC为0.7～1.6 mS/cm).     

Evaluation on Tolerance of Montmorillonite as a Mycotoxin Adsorbent

In order to study the tolerance dose of Kunming mice to montmorillonite as a mycotoxin adsorbent in diets,the experiment selected 60 healthy male Kunming mice with initial average body weight of (17±0.12)g,randomly divided them into 5 treatments with two replicates per group and 6 mice per replicate.Five experimental diets were added to 0 (control group),0.5%,1%,2% and 5% montmorillonite,respectively.After 30 days,the growth performance,nutrients apparent digestibility,serum biochemical indices and internal organization were tested to determine the tolerance dose of montmorillonite for Kunming mice.The results showed that the ADFI was significantly increased in 0.5% group (P< 0.05),while there were no significant differences in ADFI and ADG between 1% group and control group (P> 0.05),then the ADFI was significantly decreased with the increasing of montmorillonite supplemental level (P< 0.05).The ADG in 2% group had no significant difference when compared with the control group (P> 0.05),while significantly lower than that in 0.5% and 1% groups (P< 0.05).The apparent digestibility of DM,CP and EE showed no significant effect at any level of montmorillonite (P> 0.05).Serum ALT,AST activities and MDA content were gradually increased with the montmorillonite supplemental level increasing,and that in 1%,2% and 5% groups were significantly higher than that in control group (P< 0.05),but there were no significant differences between 0.5% group and control group (P> 0.05).Tissue sections showed that mice livers were damaged in varying degrees when the montmorillonite supplemental level was 5%.In conclusion,based on a comprehensive consideration of all indexes,it could be seen that the tolerance dose of the tested montmorillonite for Kunming mice was between 0.5% and 2% when mycotoxin contents in diets were in security range.
