In order to prepare Cd_(x)Zn_(1-x)S films with lower cadmium content and better performance as a buffer layer for copper indium gallium selenide(CIGS) solar cells,the performance of Cd_(x)Zn_(1-x)S films deposited in ...In order to prepare Cd_(x)Zn_(1-x)S films with lower cadmium content and better performance as a buffer layer for copper indium gallium selenide(CIGS) solar cells,the performance of Cd_(x)Zn_(1-x)S films deposited in a mixture of solutions containing extremely low cadmium sources was systematically investigated by chemical bath deposition(CBD) with the synergy of chemical experiments and numerical simulations.The experimental results show that the films have the best overall performance at a cadmium source condition of 0.007 M.展开更多
蟠桃(Prunus persica ‘Compressa’)果实扁平性状是质量性状,由S (saucer-shaped)位点控制。利用番茄(Lycopersicon esculentum)果实形状控制基因,搜寻蟠桃基因组中S位点的候选基因,筛选到一个基因——Ovate Family Protein 1 (PpOFP1)...蟠桃(Prunus persica ‘Compressa’)果实扁平性状是质量性状,由S (saucer-shaped)位点控制。利用番茄(Lycopersicon esculentum)果实形状控制基因,搜寻蟠桃基因组中S位点的候选基因,筛选到一个基因——Ovate Family Protein 1 (PpOFP1);利用转录组数据,分析候选基因在不同组织中的表达模式,确定其编码一个由421个氨基酸构成的卵形家族蛋白(OVATE family protein),含有N端核定位信号和C端ovate结构域,为拟南芥(Arabidopsis thaliana) AtOFP1直系同源物。利用实时荧光定量PCR (qRT-PCR)方法检测候选基因在不同桃树品种中的表达模式,发现PpOFP1基因在被检测的蟠桃品种中的表达量均显著高于圆桃品种以及蟠桃芽变后的圆形桃。综上,桃树PpOFP1是一个控制蟠桃果实扁平性状的重要基因,是S位点的候选基因。展开更多
