| 5 | Senescence-Inducible Expression of Isopentenyl Transferase Extends Leaf Life,Increases Drought Stress Resistance and Alters Cytokinin Metabolism in Cassava显示文摘Cassava(Manihot esculenta Crantz) sheds its leaves during growth,especially within the tropical dry season.With the production of SAG12-IPT transgenic cassava we want to test the level of leaf retention and altered cytokinin metabolism of transgenic plants via the autoregulatory senescence inhibition system.After confirmation of transgene expression by molecular analysis and phenotype examination in greenhouse plants,two transgenic plant lines,529-28 and 529-48,were chosen for further investigation.Detached mature leaves of 529-28 plants retained high levels of chlorophyll compared with wild-type leaves after dark-induced senescence treatment.Line 529-28 showed significant drought tolerance as indicated by stay-green capacity after drought stress treatment.Field experiments proved that leaf senescence syndrome was significantly delayed in 529-28 plants in comparison with wild-type and 529-48 plants.Physiological and agronomical characterizations of these plants also revealed that the induced expression of IPT had effects on photosynthesis,sugar allocation and nitrogen partitioning.Importantly,the 529-28 plants accumulated a high level of trans-zeatin-type cytokinins particularly of corresponding storage O-glucosides to maintain cytokinin homeostasis.Our study proves the feasibility of prolonging the leaf life of woody cassava and also sheds light on the control of cytokinin homeostasis in cassava leaves. | Peng Zhang Wen-Quan Wang Gen-Liang Zhang Miroslav Kaminek Petre Dobrev Jia Xu Wilhelm Gruissem | 2010 | Journal of Integrative Plant Biology2010，52，7： | 18 |

| 8 | Plant Surfaces:Structures and Functions for Biomimetic Innovations显示文摘An overview of plant surface structures and their evolution is presented. It combines surface chemistry and architecture with their functions and refers to possible biomimetic applications. Within some 3.5 billion years biological species evolved highly complex multifunctional surfaces for interacting with their environments: some 10 million living prototypes(i.e., estimated number of existing plants and animals) for engineers. The complexity of the hierarchical structures and their functionality in biological organisms surpasses all abiotic natural surfaces: even superhydrophobicity is restricted in nature to living organisms and was probably a key evolutionary step with the invasion of terrestrial habitats some 350–450 million years ago in plants and insects. Special attention should be paid to the fact that global environmental change implies a dramatic loss of species and with it the biological role models. Plants, the dominating group of organisms on our planet, are sessile organisms with large multifunctional surfaces and thus exhibit particular intriguing features.Superhydrophilicity and superhydrophobicity are focal points in this work. We estimate that superhydrophobic plant leaves(e.g., grasses) comprise in total an area of around 250 million km^2, which is about 50% of the total surface of our planet. A survey of structures and functions based on own examinations of almost 20,000 species is provided, for further references we refer to Barthlott et al.(Philos. Trans. R. Soc. A 374: 20160191, 1). A basic difference exists between aquatic nonvascular and land-living vascular plants; the latter exhibit a particular intriguing surface chemistry and architecture. The diversity of features is described in detail according to their hierarchical structural order. The first underlying and essential feature is the polymer cuticle superimposed by epicuticular wax and the curvature of single cells up to complex multicellular structures. A descriptive terminology for this diversity is provided. Simplified, the functions of plant surface characteristics may be grouped into six categories:(1) mechanical properties,(2) influence on reflection and absorption of spectral radiation,(3) reduction of water loss or increase of water uptake, moisture harvesting,(4) adhesion and nonadhesion(lotus effect, insect trapping),(5) drag and turbulence increase, or(6) air retention under water for drag reduction or gas exchange(Salvinia effect). This list is far from complete. A short overview of the history of bionics and the impressive spectrum of existing and anticipated biomimetic applications are provided. The major challenge for engineers and materials scientists, the durability of the fragile nanocoatings, is also discussed. | Wilhelm Barthlott Matthias Mail Bharat Bhushan Kerstin Koch | 2017 | Nano-Micro Letters2017，9，2： | 16 |

| 11 | Prospective cohort comparison of flavonoid treatment in patients with resected colorectal cancer to prevent recurrence显示文摘AIM: To investigate biological prevention with flavonoids the recurrence risk of neoplasia was studied in patients with resected colorectal cancer and after adenoma polypectomy. METHODS: Eighty-seven patients, 36 patients with resected colon cancer and 51 patients after polypectomy, were divided into 2 groups: one group was treated with a flavonoid mixture (daily standard dose 20 mg apigenin and 20 mg epigallocathechin-gallat, n = 31) and compared with a matched control group (n = 56). Both groups were observed for 3-4 years by surveillance colonoscopy and by questionnaire. RESULTS: Of 87 patients enrolled in this study, 36 had resected colon cancer and 29 of these patients had surveillance colonoscopy. Among the flavonoid-treated patients with resected colon cancer (n = 14), there was no cancer recurrence and one adenoma developed. In contrast the cancer recurrence rate of the 15 matched untreated controls was 20% (3 of 15) and adenomas evolved in 4 of those patients (27%). The combined recurrence rate for neoplasia was 7% (1 of 14) in the treated patients and 47% (7 of 15) in the controls (P = 0.027). CONCLUSION: Sustained long-term treatment with a flavonoid mixture could reduce the recurrence rate of colon neoplasia in patients with resected colon cancer. | Harald Hoensch Bertram Groh Lutz Edler Wilhelm Kirch | 2008 | World Journal of Gastroenterology2008，14，14： | 12 |

| 17 | Environmental responsibilities of livestock feeding using trace mineral supplements显示文摘Trace elements are essential dietary components for livestock species. However, they also exhibit a strong toxic potential. Therefore, their fluxes through the animal organism are tightly regulated by a complex molecular machinery that controls the rate of absorption from the gut lumen as well as the amount of excretion via faeces, urine and products(e.g., milk) in order to maintain an internal equilibrium. When supplemented in doses above the gross requirement trace elements accumulate in urine and faeces and, hence, manure. Thereby, trace element emissions represent a potential threat to the environment. This fact is of particular importance in regard to the widely distributed feeding practice of pharmacological zinc and copper doses for the purpose of performance enhancement. Adverse environmental effects have been described, like impairment of plant production, accumulation in edible animal products and the water supply chain as well as the correlation between increased trace element loads and antimicrobial resistance. In the light of discussions about reducing the allowed upper limits for trace element loads in feed and manure from livestock production in the European Union excessive dosing needs to be critically reconsidered. Moreover, the precision in trace element feeding has to be increased in order to avoid unnecessary supplementation and, thereby, heavy metal emissions from livestock production. | Daniel Brugger Wilhelm M.

| 18 | 气液交叉流脱除亚微米级颗粒物的研究显示文摘亚微米级颗粒是化学工业尾气排放物的重要组成,其脱除效率是影响排放指标进一步提高的关键。基于颗粒捕获机理,建立了气液交叉流系统脱除效率的理论模型,并对该系统脱除亚微米级颗粒的特性进行了理论分析和实验研究。实验结果表明,低气速、高液柱群比表面积、高气液相温差有利于提升系统的脱除效率。粒径0.05~0.6μm,脱除效率随粒径的增大呈现先降低后增加的趋势,与理论值趋势一致,表明系统中同时存在惯性碰撞、拦截、布朗运动等三种脱除机理。相对于理论值,实验脱除率整体偏大,表明颗粒在高湿环境中易凝并,有助于颗粒在碰撞和拦截作用下的脱除。由实验数据外推,研究条件下,液柱单元排数为1300时,亚微米级颗粒质量脱除效率预计可达90%。 | 徐挺 魏文韫 孙白宇 杨雅琪 刘凌岭 余徽 Thomas Laminger Wilhelm Hoeflinger | 2017 | 高校化学工程学报2017，31，4： | 7 |

| 20 | INFLUENCE OF AIR HUMIDITY ON THE SUPPRESSION OF FUGITIVE DUST BY USING A WATER-SPRAYING SYSTEM显示文摘One of the main origins of fugitive dust emission arises from bulk handling in quarries or mines, in par- ticular, from bulk materials falling from a hopper or a conveyor belt. Water-spraying systems, using two-phase nozzles, are one of the methods to suppress such dust emission. In this work we tried to develop a mathematical model to cor- relate air humidity, water flux through the nozzle and the dust (in particular PM10) emission, in order to improve the ap- plication and efficiency of these systems. Sand from the Yellow River in China was dropped from a conveyor belt into a dust chamber at 1 kg?min-1, wherefrom the emitted dust was sucked off and quantified via a cascade impactor. A two-phase nozzle was installed in the dust chamber with a water flux through the nozzle of 1.2 to 3 L?h-1, whereas the relative air humidity changed between 55 and 73%. Dust emission was found to be linearly dependent on relative air humidity. Furthermore model equations were developed to describe the dependence of PM10 emission on water flux and relative air humidity. | Peter Werner Grundnig Wilhelm Hoeflinger Gerd Mauschitz Zechang Liu Guiqin Zhang Zhiqiang Wang | 2006 | China Particuology2006，4，5： | 6 |
