| 1 | Studies on the Element Characteristics of Nephrite Minerals from Different Deposits by GD-MS显示文摘软玉矿物质的元素特征被发光分泌物团 spectrometry (GDMS ) 通过表面坚持方法决定。解决非传导性的软玉样品的传导性问题,高纯净铟大头针(>99.9999%) 是被使用分泌物主人。在准备过程期间,软玉样品的一小片被磨成粉末(大约 200 个网孔) ,然后样品粉末在铟大头针的表面上是涂的形成一件杆样品。软玉矿物质的典型元素被 GDMS 分析,并且相对标准差证明这个方法的稳定性和重制度好。同时,从二不同沉积物的四件软玉样品被这个方法进一步学习。主要元素和踪迹元素的 GDMS 结果表明从一样的沉积物的软玉矿物质的典型元素是类似的,并且那些从不同沉积物展出了重要差别。另外,外部横梁的质子的结果导致了 X 光检查排放(PIXE ) 与 GDMS 决心的结果一致。现在的途径被证明了简单,有效软玉的半量的分析取样执行快速的屏蔽和多元素。 | Siqinbilige Qian, Rong Zhuo, Shangjun Gan, Fuxi | 2011 | Chinese Journal of Chemistry2011，29，6： | 3 |
| 2 | Cadmium induced a non-coding RNA microRNA535 mediates Cd accumulation in rice显示文摘Identifying key regulators related to cadmium(Cd)tolerance and accumulation is the main factor for genetic engineering to improve plants for bioremediation and ensure crop food safety.MicroRNAs(miRNAs),as fine-tuning regulators of genes,participate in various abiotic stress processes.MiR535 is an ancient conserved non-coding small RNA in land plants,positively responding to Cd stress.We investigated the effects of knocking out(mir535)and overexpressing miR535(mir535 and OE535)under Cd stress in rice plants in this study.The mir535 plants showed better Cd tolerance than wild type(WT),whereas the OE535 showed the opposite effect.Cd accumulated approximately 71.9%and 127%in the roots of mir535 and OE535 plants,respectively,compared to WT,after exposure to 2μmol/L Cd.In brown rice,the total Cd accumulation of OE535 and mir535 was about 78%greater and 35%lower than WT.When growing in 2 mg/kg Cd of soil,the Cd concentration was significantly lower in mir535 and higher in OE535 than in the WT;afterward,we further revealed the most possible target gene SQUAMOSA promoter binding-like transcription factor 7(SPL7)and it negatively regulates Nramp5 expression,which in turn regulates Cd metabolism.Therefore,the CRISPR/Cas9 technology may be a valuable strategy for creating new rice varieties to ensure food safety. | Erkui Yue Fuxi Rong Zhen Liu Songlin Ruan Tao Lu Haifeng Qian | 2023 | Journal of Environmental Sciences2023，，8： | 1 |
| 3 | OsbZIP01 Affects Plant Growth and Development by Regulating OsSD1 in Rice显示文摘As the‘Green Revolution’gene,SD1(encoding GA20ox2),has been widely applied to improve yield in rice breeding.However,research on its transcriptional regulation is limited.Here,we identified a transcription factor OsbZIP01,which can suppress the expression of SD1 and regulate gibberellin(GA)biosynthesis in rice.Knockout mutants of OsbZIP01 exhibited increased plant height,while the overexpression lines showed a semi-dwarf phenotype and diminished germination rate.Furthermore,the semi-dwarf phenotype of OE-bZIP01,was caused by the reduced internode length,which was accompanied by a thin stem width.The predominant expression of OsbZIP01 was observed in leaves and sheaths.OsbZIP01 protein was localized in the nucleus and showed transcriptional repression activity.In addition,OsbZIP01 could directly bind to the promoter of the OsSD1 gene,and inhibit its transcription.The semi-dwarf phenotype of OE-bZIP01 could be rescued by exogenous GA_(3).Meanwhile,the bzip01 sd1 double mutant showed a shorter shoot length compared with the wild type,indicating that OsbZIP01 regulated plant growth mainly through the GA biosynthesis pathway.Collectively,OsbZIP01 negatively regulates GA biosynthesis by restraining SD1 transcription,thereby affecting plant growth and development. | DONG Xinli ZHOU Yang ZHANG Yaqi RONG Fuxi DU Jiahong HONG Zheyuan HU Peisong LÜYusong | 2024 | Rice science2024，31，1： | 0 |
