3Gene Network Analysis and Functional Studies of Senescence-associated Genes Reveal Novel Regulators of Arabidopsis Leaf Senescence显示文摘Plant leaf senescence has been recognized as the last phase of plant development, a highly ordered process regulated by genes known as senescence associated genes (SAGs). However, the function of most of SAGs in regulating leaf senescence as well as regulators of those functionally known SAGs are still unclear. We have previously developed a curated database of genes potentially associated with leaf senescence, the Leaf Senescence Database (LSD). In this study, we built gene networks to identify common regulators of leaf senescence in Arabidopsis thaliana using promoting or delaying senescence genes in LSD. Our results demonstrated that plant hormones cytokinin, auxin, nitric oxide as well as small molecules, such as Ca2+, delay leaf senescence. By contrast, ethylene, ABA, SA and JA as well as small molecules, such as oxygen, promote leaf senescence, altogether supporting the idea that phytohormones play a critical role in regulating leaf senescence. Functional analysis of candidate SAGs in LSD revealed that a WRKY transcription factor WRKY75 and a Cys2/His2-type transcription factor AZF2 are positive regulators of leaf senescence and loss-of-function of WRKY75 or AZF2 delayed leaf senescence. We also found that silencing of a protein phosphatase, AtMKP2, promoted early senescence. Collectively, LSD can serve as a comprehensive resource for systematic study of the molecular mechanism of leaf senescence as well as offer candidate genes for functional analyses.Zhonahai Li Jinying Peng Xing Wen Hongwei Guo 2012Journal of Integrative Plant Biology2012,54,8:21

5Promoting ring-opening efficiency for suppressing toxic intermediates during photocatalytic toluene degradation via surface oxygen vacancies显示文摘Aromatic ring-opening process is well recognized as the rate-determining step for catalytic toluene degradation. In photocatalytic toluene degradation, the toxic intermediates w让h harmful effects may be generated. To clarify the precise reaction mechanism and control the toxic intermediates generation, a closely combined in situ DRIFTS and DFT calculation is utilized to address these important issues. We construct the BiOCl w让h oxygen vacancies (OVs) and reveal the structure of OVs. The defect level caused by oxygen vacancies could promote the light adsorption and charge separation, which further boosts the activation of ring-opening species and enhances the generation process of free radicals. The reaction energy barriers of four possible ring-opening processes on defective BiOCl (OVBOC) are all declined in comparison with perfect BiOCl (BOC). The existence of oxygen vacancies could smooth the ratedetermining step so the ring-opening efficiency of photocatalytic toluene degradation is highly increased. Most importantly, the methyl species would be further oxidized and tend to open the benzene-ring at benzoic acid on BOC while the ring would be broken at the benzyl alcohol on OVBOC. These results indicate that the toluene degradation pathway is shortened via the surface OVs, which enables the production of radicals with high oxidation capability for the accelerated chain scission of the ring-opening intermediates. Finally, the efficiency of the key ring-opening process could be enormously improved and toxic intermediates are effectively restrained. The present work could provide new insights into the design of high-performance photocatalysts for efficient and safe degradation of VOCs in air.Xing'an Dong Wen Cui Hong Wang Jieyuan Li Yanjuan Sun Haiqiang Wang Yuxin Zhang Hongwei Huang Fan Dong 2019Science Bulletin2019,64,10:9
6Oxygen adsorption/desorption behavior of YBaCo4O7+δ and its application to oxygen removal from nitrogen显示文摘A new medium-temperature (200-400℃) adsorbent material for oxygen removal and air separation, YBaCo4O7+β, was prepared by the solid-state reaction method. This new adsorbent could adsorb a large quantity of oxygen in the temperature range of 200-370 ℃. Ad-sorbed oxygen could be released by raising temperature over 400 ℃ or by switching the atmosphere from oxygen to nitrogen. This oxygen adsorption and desorption process had good reproducibility. Taking advantage of this unique oxygen intake/release behavior, a nitrogen puri-fication process was investigated. The results showed that YBaCo4O7+δ material was a promising candidate for the oxygen sorption process and could be used to produce high-purity nitrogen or to remove trace oxygen from other gases.HAO Haoshan ZHAO Limin FIU Jie HU Xing HOU Hongwei 2009Journal of Rare Earths2009,27,5:8
7DELLA proteins interact with FLC to repress flowering transition显示文摘Flowering is a highly orchestrated and extremely ct critical process in a plant's life cycle. Previous study has ademonstrated that SUPPRESSOR OF OVEREXPRESSION OF pCONSTANS 1(SOC1) and FLOWERING LOCUS T(FT) integrate m-I the gibberellic acid(GA) signaling pathway and vernalization higpathway in regulating flowering time, but detailed molecular Hmechanisms remain largely unclear. In GA signaling pathway,DELLA proteins are a group of master transcriptional regulators, while in vernalization pathway FLOWERING LOCUS C(FLC) is a core transcriptional repressor that down-regulates the expression of SOC1 and FT. Here, we report that DELLA proteins interact with FLC in vitro and in vivo, and the LHRI domains of DELLAs and the C-terminus of MADS domain of FLC are required for these interactions.Phenotypic and gene expression analysis showed that mutation of FLC reduces while over-expression of FLC enhances the GA response in the flowering process. Further,DELLA-FLC interactions promote the repression ability of FLC on its target genes. In summary, these findings report that the interaction between MADS box transcription factor FLC and GRAS domain regulator DELLAs may integrate various signaling inputs in flowering time control, and shed new light on the regulatory mechanism both for FLC and DELLAs in regulating gene expression.Mingzhe Li Fengying An Wenyang Li Mengdi Ma Ying Feng Xing Zhang Hongwei Guo 2016Journal of Integrative Plant Biology2016,58,7:7
8Cellulose-hydrogen production from corn stalk biomass by anaerobic fermentation显示文摘Cellulose-hydrogen production from corn stalk by lesser panda manure was carried out in batch tests and a 5 L scale-up continuously stirred anaerobic bioreactor(CSABR),respectively.The bio-pretreatment of corn stalk was found most effective at 25℃ using microbe additive of 7.5 g/kg,in which the yields of soluble saccharides(SS) and lactic acid were 212 mg/g-TS and 21 mg/g-TS,respectively.The maximum cumulative H2 yield(176 ml/g-TS) and H2 production rate(14.5 ml/g-TS h-1) were obtained at pH 5.5,36℃ by treating a substrate of 15 g/L.The hydrogen content in biogas was 57.2% and there was no significant methane gas observed.During the optimal period of H2 production,the ORP values stayed in the lower level ranging from -445 mV to -455 mV.The results show that the bio-pretreatment of the raw materials played a vital role in the effective conversion of corn stalk into cellulose-hydrogen by mixed culture.XING Yan MA HongCui FAN YaoTing HOU HongWei CHEN JingRun 2009Chinese Science Bulletin2009,54,8:3

10Dynamic rupture of metal sheet subjected to laser irradiation and tangential subsonic airflow显示文摘To reproduce the premature rupture process of metal sheet subjected to laser irradiation with subsonic airflow,which is an interesting phenomenon observed in the experiments given by Lawrence Livermore National Laboratory,a coupled numerical model considering the interaction and evolution of metal elastoplastic deformation and aerodynamic pressure profile is presented.With the thermal elastoplastic constitutive relationship and failure criterion,the simulated failure modes and dynamic rupture process are basically consistent with the experimental results,indicating plastic flow and multiple fracturing is the main failure mechanism.Compared with the case of non-airflow,subsonic airflow not only accelerates deformation,but also turns the bugle deformation,plastic strain and rupture mode into asymmetric.Xiaodong Xing Te Ma Ruixing Wang Chenyu Cao Hongwei Song Chenguang Huang 2018Theoretical & Applied Mechanics Letters2018,8,4:2

15Serial wavelength division 1 GHz line-scan microscopic imaging显示文摘A serial line scan microscopic imaging system with 1 GHz scan rate is proposed and demonstrated.This method is based on optical time-stretch in dispersive fiber to realize superfast scan imaging.Furthermore,a wavelength division technique is utilized to overcome the trade-off between high frame rate and spatial resolution caused by dispersion-induced pulse overlap.Every single frame is carved into two channels by optical filters and is detected in different wavelength bands separately.Then,both channels are combined to reconstruct the whole frame.By this method,an imaging system with spatial resolution of 28μm at line scan rate of 1 GHz with chromatic dispersion of 1377 ps∕nm is realized.It has the potential to capture fast,nonrepetitive transient phenomena with a timescale of less than one nanosecond.Fangjian Xing Hongwei Chen Cheng Lei Zhiliang Weng Minghua Chen Sigang Yang Shizhong Xie 2014Photonics Research2014,2,4:1

20Relationship between plant species diversity and patch characteristics in a marsh in the Sangjiang Plain,China—Using Yaluhe farm as an example显示文摘Based on Quick Bird satellite image data, the present study examined small-scale herbaceous community patches in the marsh of the Sanjiang Plain and measured patch characteristics such as the area, perimeter and shape by GPS. The coenological characteristics of the patches were investigated using quadrat method, and the vascular plant species were recorded using transect method. A total of 219 plant species were recorded, which represents 12.2% of the vascular flora in Heilongjiang Province. Our results showed that species number S correlated with patch area and perimeter; richness index (R) correlated with patch perimeter; Simpson index (D) correlated with patch area and perimeter/area; Shannon-Wiener index (H′) correlated with patch area, perimeter and perimeter/area; Evenness index (Jsw) correlated with perimeter/area. Both S and R have significant difference between different size of patches. Plant diversity in the small-scale herbaceous communities tended to increase with the patch area and perimeter. We concluded that edge effects and the habitat heterogeneity of the patches are important in determining the number of species. The relative smoothness of the patch edges also affects the plant diversity of the patches. The richness of plant species in the marsh in the Sanjiang Plain is highly sensitive to the small-scale patches, which continues to play an important role in preserving plant diversity in the local area.Sun Zhonglin Xing Fu Lu Xianguo Xu Kun Yu Lili Ni Hongwei 2007Progress in Natural Science:Materials International2007,17,6:1
