Tillage represents an important practice that is used to dynamically regulate soil properties,and affects the grain production process and resource use efficiency of *** objectives of this 3-year field study carried out in the huang-Huai-Hai(HHH) Plain of china were to compare the effects of a new deep vertical rotary tillage (DVRT) with the conventional shallow rotary tillage (CT) on soil properties,winter wheat (Triticum aestivum L.) grain yield and water and nitrogen use efficiency at different productivity levels,and to identify a comprehensive management that optimizes both grain yield and resource use efficiency in the HHH Plain.A split-plot design was adopted in field experiments in the winter wheat growing seasons of 2016–2017 (S1),2017–2018 (S2) and 2018–2019 (S3),with DVRT (conducted once in June 2016) and CT performed in the main *** were treated with one of four targeted productivity level treatments (SH,the super high productivity level;HH,the high productivity and high efficiency productivity level;FP,the farmer productivity level;ISP,the inherent soil productivity level).The results showed that the soil bulk density was reduced and the soil water content at the anthesis stage was increased in all three years,which were due to the significant effects of *** with CT,grain yields,partial factor productivity of nitrogen (PFP_(N)),and water use efficiency (wuE) under DVRT were increased by 22.0,14.5 and 19.0%.Path analysis and direct correlation decomposition uncovered that grain yield variation of winter wheat was mostly contributed by the spike numbers per area under different tillage *** line model analysis revealed that tillage mode played a significant role on grain yield,PFP_(N) and wuE not only as a single factor,but also along with other factors(year and productivity level) in interaction *** addition,PFP_(N) and wuE were the highest in HH under DVRT in all three growth *** results provided a th

文章利用已建立的苏太猪F18大肠杆菌病抗性和敏感性资源家系群体作为实验材料,分别选择8头35日龄左右生长性状基本一致的大肠杆菌F18菌株抗性和敏感性断奶仔猪,运用Real-time PCR方法检测BPI基因mRNA在断奶仔猪各个组织的分布情况,并比较其在大肠杆菌F18菌株抗性型和敏感型断奶仔猪个体间的差异表达水平,为探讨该基因在免疫和抗大肠杆菌F18菌株感染中的作用提供依据。结果表明,在对所有个体检测的11个组织中,BPI基因在心、肝、脾、肺、肾、胃、肌肉、胸腺、淋巴结中几乎不表达,或表达量很低,但在十二指肠和空肠中表达量很高。在十二指肠和空肠中,BPI基因在抗性组的表达量均显著高于敏感组的表达量(P5)。由此表明,BPI基因对抗断奶仔猪肠道中大肠杆菌F18菌株的感染可能具有直接作用,并且个体对大肠杆菌F18菌株的抗性可能与BPI基因在肠道中表达量上调有关。

文章采用PCR-SSCP方法对亚洲野猪、3个引进的商业化品种和10个中国地方猪品种共893个个体TLR4基因外显子1的遗传变异进行了检测,旨在系统分析国内外猪种TLR4基因的多态性,为探讨该基因在免疫和防御系统中发挥的作用提供依据。结果,在猪TLR4基因外显子1中分离到新的等位基因,共检测到3个等位基因,6种基因型。其中杜洛克检测到AA、BB、CC、AB、AC、BC基因型,有杜洛克血统的苏太猪中检测到BB、CC、BC基因型,长白猪、约克夏中检测到CC、BC基因型,野猪及所有10个中国地方猪品种TLR4基因外显子1高度保守,只检测到CC基因型,中国地方猪品种和引进品种TLR4基因外显子1多态性存在极显著的差异。3种基因型中CC型与GenBank中的序列一致,BB和AA基因型分别存在G93C同义突变位点和G194A无义突变位点,这2个变异位点与抗逆性和一般抗病力的关系值得进一步深入研究。
