| 1 | Senescence-specific Alteration of Hydrogen Peroxide Levels in Arabidopsis thaliana and Oilseed Rape Spring Variety Brassica napus L.cv.Mozart显示文摘In order to analyze the signaling function of hydrogen peroxide (H2O2) production in senescence in more detail, we manipulated intracellular H2O2 levels in Arabidopsis thaliala (L.) Heynh by using the hydrogen-peroxide-sensitive part of the Escherichia coli transcription regulator OxyR, which was directed to the cytoplasm as well as into the peroxisomes. H2O2 levels were lowered and senescence was delayed in both transgenic lines, but OxyR was found to be more effective in the cytoplasm. To transfer this knowledge to crop plants, we analyzed oilseed rape plants Brassica napus L. cv. Mozart for H2O2 and its scavenging enzymes catalase (CAT) and ascorbate peroxidase (APX) during leaf and plant development. H2O2 levels were found to increase during bolting and flowering time, but no increase could be observed in the very late stages of senescence. With increasing H2O2 levels, CAT and APX activities declined, so it is likely that similar mechanisms are used in oilseed rape and Arabidopsis to control H2O2 levels. Under elevated CO2 conditions, oilseed rape senescence was accelerated and coincided with an earlier increase in H2O2 levels, indicating that H2O2 may be one of the signals to inducing senescence in a broader range of Brassicaceae. | Stefan Bieker Lena Riester Mark Stahl Jürgen Franzaring Ulrike Zentgraf | 2012 | Journal of Integrative Plant Biology2012，54，8： | 3 |

| 8 | Source-specific risk assessment for cadmium in wheat and maize:Towards an enrichment model for China显示文摘Cadmium (Cd) pollution of agricultural soil is of public concern due to its high potential toxicity and mobility.This study aimed to reveal the risk of Cd accumulation in soil and wheat/maize systems,with a specific focus on the source-specific ecological risk,human health risk and Cd enrichment model.For this we investigated more than 6100 paired soil and grain samples with 216 datasets including soil Cd contents,soil pH and grain Cd contents of 85 sites from China.The results showed that mining activities,sewage irrigation,industrial activities and agricultural practices were the critical factors causing Cd accumulation in wheat and maize cultivated sites.Thereinto,mining activities contributed to a higher Cd accumulation risk in the southwest China and Middle Yellow River regions;sewage irrigation influenced the Cd accumulation in the North China Plain.In addition,the investigated sites were classified into different categories by comparing their soil and grain Cd contents with the Chinese soil screening values and food safety values,respectively.Cd enrichment models were developed to predict the Cd levels in wheat and maize grains.The results showed that the models exhibited a good performance for predicting the grain Cd contents among safe and warning sites of wheat (R2=0.61 and 0.72,respectively);while the well-fitted model for maize was prone to the overestimated sites (R2=0.77).This study will provide national viewpoints for the risk assessments and prediction of Cd accumulation in soil and wheat/maize systems. | Zhong Zhuang Qiqi Wang Siyu Huang Andrea Giovanna NinoSavala Yanan Wan Huafen Li Andreas H.Schweiger Andreas Fangmeier Jürgen Franzaring | 2023 | Journal of Environmental Sciences2023，，3： | 1 |
