Over-expression of the AtGA2ox8 gene decreases the biomass accumulation and lignification in rapeseed (Brassica napus L.)

Journal of Zhejiang University-Science B(Biomedicine & Biotechnology) 2010年第7期11卷 471-481页

Gibberellin 2-oxidase (GA 2-oxidase) plays very important roles in plant growth and development. In this study, the AtGA2ox8 gene, derived from Arabidopsis (Arabidopsis thaliana), was transformed and over-expressed in rapeseed (Brassica napus L.) to assess the role of AtGA2ox8 in biomass accumulation and lignification in plants. The transgenic plants, identified by resistant selection, polymerase chain reaction (PCR) and reverse-transcription PCR (RT-PCR) analyses, and green fluorescence examination, showed growth retardation, flowering delay, and dwarf stature. The fresh weight and dry weight in transgenic lines were about 21% and 29% lower than those in wild type (WT), respectively, and the fresh to dry weight ratios were higher than that of WT. Quantitative measurements demonstrated that the lignin content in transgenic lines decreased by 10%-20%, and histochemical staining results also showed reduced lignification in transgenic lines. Quantitative real-time PCR analysis indicated that the transcript levels of lignin biosynthetic genes in transgenic lines were markedly decreased and were consistent with the reduced lignification. These results suggest that the reduced biomass accumulation and lignification in the AtGA2ox8 over-expression rapeseed might be due to altered lignin biosynthetic gene expression.

以柠檬酸和尿素为反应原料、乙二醇为反应溶剂，采用溶剂热法合成了荧光碳点（Carbon dots,CDs），并对CDs的形貌、粒径、晶体结构、元素成分、表面基团和光学性质等进行了表征。研究了CDs对激发光依赖的荧光发射特性，讨论了反应温度、反应时间和原料比例等合成条件对CDs的激发波长和发射波长的影响。将CDs与淀粉、纳米二氧化硅、蒙脱土、高岭土、硅藻土和氧化镁6种基质复合，制备出一系列CDs荧光复合物。最终将CDs-淀粉荧光复合物应用于光滑客体表面潜在手印的增强显现，并从定性和定量两个层面对显现效果进行了详细评价。利用CDs-淀粉荧光复合物对激发光依赖的荧光发射特性，结合滤光拍照，在很大程度上降低了客体背景噪声干扰。手印显现结果表明，显现信号与客体背景噪声之间的对比反差明显，具有较强的显现对比度；显现手印的各级特征反映清晰，具有较高的显现灵敏度；显现粉末与手印遗留物质之间的结合程度较高，具有较好的显现选择性。
