The envelope fusion protein F of baculoviruses is a class I viral fusion protein which play a significant role during virus entry into insect cells. F is initially synthesized as a precursor（F_0） and then cleaved into a disulfide-linked F_1 and F_2 subunits during the process of protein maturation and secretion. To facilitate further investigation into the structure and function of F protein during virus infection, monoclonal antibodies（mAbs） against the F_2 subunit of Helicoverpa armigera nucleopolyhedrovirus（HearNPV）（Ha F） were generated. Two kinds of mAbs were obtained according to their different recognition epitopes： one kind of mAbs, as represented by 38F10,recognizes amino acid（aa） 85 to 123 of F_2 and the other kind, represented by 44D11, recognizes aa148 to 173 of F_2. Western blot and immunofluorescence assay confirmed that both of the mAbs recognized the F protein expressed in HearNPV infected cells, however, only 44D11 could neutralize HearNPV infection. The results further showed that 44D11 may not interact with a receptor binding epitope, rather it was demonstrated to inhibit syncytium formation in cells expressing the Ha F protein. The results imply that the monoclonal antibody 44D11 recognizes a region within HaF_2 that may be involved in the F-mediated membrane fusion process. 基金

基于课题组前期的转录组数据筛选到CsDREB11、CsDREB15和CsDREB25等基因。通过RT-qPCR验证,它们均受干旱诱导表达。从进化树、蛋白理化性质、亲/疏水性、二级和三级结构、亚细胞定位等方面进行预测与分析。结果表明,CsDREB11、CsDREB15和CsDREB25都与狭叶油茶(Camellialanceoleosa)的亲缘性最为密切,都属于不稳定的亲水性蛋白。二级/三级结构均以无规则卷曲和α-螺旋为主,其亚细胞定位均位于细胞核中。课题组前期的研究发现CsDREB25与CsPOD3均在干旱下高表达且呈显著相关,推测CsDREB25和CsPOD3存在相互作用关系。通过酵母单杂交验证(Y1H)和双荧光素酶报告基因检测(DLA)以及双荧光素酶互补成像(LCI)等方法试验验证了CsDREB25能正向调控CsPOD3的表达,提高POD的活性,清除过多活性氧,提高茶树的耐旱性。

胀裂破岩是常见的破碎岩石手段,为研究单孔岩样的胀裂效果,制作了4种不同边距的贯通、半贯通圆孔红砂岩试样。借助自制的胀裂装置,在刚性伺服机上进行单轴加载,分析不同加载速率、钻孔边距和钻孔深度下圆孔周边的裂纹扩展形式,研究不同边距下试样的破坏特征。研究发现:当边距为40 mm时,半贯通试样破坏所需的时间超过贯通试样。达到峰值荷载时,大部分半贯通试样的胀裂只在一侧产生裂纹,小部分出现2条不规则的裂纹,大部分裂纹只延伸一定长度而未贯穿至试样底部。随着边距增加,贯通试样在2种加载速率下破坏时间的差值逐步扩大,0.4 mm/min速率下试样的胀裂时长快速增加,破岩速率大幅降低,而0.8 mm/min速率下试样破坏时发生的位移更小。分析试样的局部应变发现,2种加载速率下试样的局部应变变化规律差异并不明显。研究结果表明:相比半贯通试样,贯通试样更容易发生变形,胀裂产生的裂纹水平对称;在边距和孔深一定的情况下,2种加载速率对试样的胀裂破坏差异较小。研究结果可为钻孔胀裂法破碎岩石提供参考。

使用截面加权最小二乘法对31个省市自治区面板数据进行研究,发现自然灾害变化率对农业产值增速和农民可支配收入增速具有负面影响(-0.008;-0.001),而且区域间的影响具有较大差异性,自然灾害对东西部农业增长和农民收入增速影响的差异分别是10倍和80倍。这种区域影响的异质性不仅来自于自然环境因素,也来自于区域间的社会环境因素,在无法改变区域间自然环境差异性条件下,设法提高中西部地区,尤其是西部地区社会环境因素,是抵消自然灾害对农业、农民影响的现实举措。
