2Hydrogen Sulfide Promotes Wheat Seed Germination and Alleviates Oxidative Damage against Copper Stress显示文摘With the enhancement of copper(Cu) stress,the germination percentage of wheat seeds decreased gradually. Pretreatment with sodium hydrosulfide(NaHS),hydrogen sulfide(H2S) donor alleviated the inhibitory effect of Cu stress in a dose-dependent manner; whereas little visible symptom was observed in germinating seeds and radicle tips cultured in NaHS solutions. It was verified that H2S or HS-rather than other sulfur-containing components derived from NaHS attribute to the potential role in promoting seed germination against Cu stress. Further studies showed that NaHS could promote amylase and esterase activities,reduce Cu-induced disturbance of plasma membrane integrity in the radicle tips,and sustain lower levels of malondialdehyde and H2O2 in germinating seeds. Furthermore,NaHS pretreatment increased activities of superoxide dismutase and catalase and decreased that of lipoxygenase,but showed no significant effect on ascorbate peroxidase. Alternatively,NaHS prevented uptake of Cu and promoted the accumulation of free amino acids in seeds exposed to Cu. In addition,a rapid accumulation of endogenous H2S in seeds was observed at the early stage of germination,and higher level of H2S in NaHS-pretreated seeds. These data indicated that H2S was involved in the mechanism of germinating seeds' responses to Cu stress.Hua Zhang Lan-Ying Hu Kang-Di Hu Yun-Dong He Song-Hua Wang Jian-Ping Luo 2008Journal of Integrative Plant Biology2008,50,12:93

4WRKY transcription factors in plant responses to stresses显示文摘The WRKY gene family is among the largest families of transcription factors(TFs) in higher plants.By regulating the plant hormone signal transduction pathway,these TFs play critical roles in some plant processes in response to biotic and abiotic stress.Various bodies of research have demonstrated the important biological functions of WRKY TFs in plant response to different kinds of biotic and abiotic stresses and working mechanisms.However,very little summarization has been done to review their research progress.Not just important TFs function in plant response to biotic and abiotic stresses,WRKY also participates in carbohydrate synthesis,senescence,development,and secondary metabolites synthesis.WRKY proteins can bind to W-box(TGACC(A/T)) in the promoter of its target genes and activate or repress the expression of downstream genes to regulate their stress response.Moreover,WRKY proteins can interact with other TFs to regulate plant defensive responses.In the present review,we focus on the structural characteristics of WRKY TFs and the research progress on their functions in plant responses to a variety of stresses.Jingjing Jiang Shenghui Ma Nenghui Ye Ming Jiang Jiashu Cao Jianhua Zhang 2017Journal of Integrative Plant Biology2017,59,2:75
5Unraveling salt stress signaling in plants显示文摘Salt stress is a major environmental factor limiting plant growth and productivity. A better understanding of the mechanisms mediating salt resistance will help researchers design ways to improve crop performance under adverse environmental conditions. Salt stress can lead to ionic stress, osmotic stress and secondary stresses, particularly oxidative stress, in plants. Therefore,to adapt to salt stress, plants rely on signals and pathways that re-establish cellular ionic, osmotic, and reactive oxygen species(ROS) homeostasis. Over the past two decades, genetic and biochemical analyses have revealed several core stress signaling pathways that participate in salt resistance. The Salt Overly Sensitive signaling pathway plays a key role in maintaining ionic homeostasis,via extruding sodium ions into the apoplast. Mitogenactivated protein kinase cascades mediate ionic, osmotic,and ROS homeostasis. SnR K2(sucrose nonfermenting1-related protein kinase 2) proteins are involved in maintaining osmotic homeostasis. In this review, we discuss recent progress in identifying the components and pathways involved in the plant's response to salt stress and their regulatory mechanisms. We also review progress in identifying sensors involved in salt-induced stress signaling in plants.Yongqing Yang Yan Guo 2018Journal of Integrative Plant Biology2018,60,9:66
6Volatile Organic Compounds and Their Roles in Bacteriostasis in Five Conifer Species显示文摘In order to make clear the functions of plant volatile organic compounds (VOCs) on bacteriostasis and air decontamination, we analyzed the composition and content of VOCs in Pinus tabulaeformis Carr., P. bungeana Zucc., Sabina chinensis Antoine, Picea koraiensis Nakai, and Cedrus deodara G. Don under near-natural conditions using the thermal-desorption cold trap gas chromatography/mass spectrometer technique. The effects of the VOCs on airborne microorganisms were investigated using the method of natural sedimentation. Results showed that the major VOCs were as follows: limonene, β-pinene, α-pinene,and α-caryophyllene in Pinus tabulaeformis and P. bungeana; limonene, borneol acetate, β-pinene, myrcene,and tricylene in S. chinensis; limonene, α-pinene, myrcene, camphene, and β-pinene in Picea koraiensis;and limonene, 2, (10)-pinene, α-pinene, and myrcene in C. deodara. These VOCs and the corresponding foliar extracts inhibited the growth of bacteria and stimulated the growth of fungi. Experimental data using monomers of the VOCs demonstrated that limonene, β-pinene, and three aldehydes could significantly inhibit bacterial growth, suggesting an inhibitory effect of VOCs on the growth of airborne microorganisms in the five conifer species. The bacteriostasis and air-decontaminating effects of plant VOCs are further discussed in terms of their chemical composition.YanGAO You-JuJIN Hai-DongLI Hua-JunCHEN 2005Journal of Integrative Plant Biology2005,47,4:52
7Promotion by 5-Aminolevulinic Acid of Germination of Pakchoi (Brassica campestris ssp. chinensis var. communis Tsen et Lee) Seeds Under Salt Stress显示文摘The seed germination and seedling growth of pakchoi (Brassica campestris ssp. chinensis var.communis Tsen et Lee cv. Hanxiao) were not significantly inhibited until the concentration of NaCl was increased to150 mmol/L. Treatment of pakchoi seeds with exogenous 5-aminolevulinic acid (ALA), at concentrations ranging from 0.01 to 10.00 mg/L, promoted seed germination when seeds were stressed by salinity, whereas levulinic acid (LA), an inhibitor of ALA dehydrase, significantly inhibited seed germination and seedling growth, suggesting that metabolism of ALA into porphyrin compounds was necessary for seed germination and seedling growth. Determination of respiratory rate during seed germination showed that ALA increased seed respiration under both normal conditions and salt stress. Furthermore, salt stress decreased levels of endogenous ALA, as well as heme, in etiolated seedlings. More salt-tolerant cultivars of pakchoi contained higher relative levels of endogenous ALA and heme under conditions of salt stress.These results indicate that salt stress may inhibit the biosynthesis of endogenous ALA and then heme,which is necessary for seed germination, and treatment of seeds with exogenous ALA prior to germination may be associated with the biosynthesis of heme.Liang-Ju WANG Wei-Bing JIANG Hui LIU Wei-Qin LIU Lang KANG Xi-Lin HOU 2005Journal of Integrative Plant Biology2005,47,9:54

9Hydrogen Peroxide in Plants:a Versatile Molecule of the Reactive Oxygen Species Network显示文摘Plants often face the challenge of severe environmental conditions,which include various biotic and abiotic stresses that exert adverse effects on plant growth and development. During evolution,plants have evolved complex regulatory mechanisms to adapt to various environmental stressors. One of the consequences of stress is an increase in the cellular concentration of reactive oxygen species(ROS),which are subsequently converted to hydrogen peroxide(H2O2). Even under normal conditions,higher plants produce ROS during metabolic processes. Excess concentrations of ROS result in oxidative damage to or the apoptotic death of cells. Development of an antioxidant defense system in plants protects them against oxidative stress damage. These ROS and,more particularly,H2O2,play versatile roles in normal plant physiological processes and in resistance to stresses. Recently,H2O2 has been regarded as a signaling molecule and regulator of the expression of some genes in cells. This review describes various aspects of H2O2 function,generation and scavenging,gene regulation and cross-links with other physiological molecules during plant growth,development and resistance responses.Li-Juan Quan Bo Zhang Wei-Wei Shi Hong-Yu Li 2008Journal of Integrative Plant Biology2008,50,1:52
10How Plants Cope with Cadmium: Staking All on Metabolism and Gene Expression显示文摘Environmental pollution is one of the major problems for human health. Toxic heavy metals are normally present as soil constituents or can also be spread out in the environment by human activity and agricultural techniques. Soil contamination by heavy metals as cadmium, highlights two main aspects: on one side they interfere with the life cycle of plants and therefore reduce crop yields, and on the other hand, once adsorbed and accumulated into the plant tissues, they enter the food chain poisoning animals and humans. Considering this point of view, understanding the mechanism by which plants handle heavy metal exposure, in particular cadmium stress, is a primary goal of plant-biotechnology research or plant breeders whose aim is to create plants that are able to recover high amounts of heavy metals, which can be used for phytoremediation, or identify crop varieties that do not accumulate toxic metal in grains or fruits. In this review we focus on the main symptoms of cadmium toxicity both on root apparatus and shoots. We elucidate the mechanisms that plants activate to prevent absorption or to detoxify toxic metal ions, such as synthesis of phytochelatins, metallothioneins and enzymes involved in stress response. Finally we consider new plant-biotechnology applications that can be applied for phytoremediation.Giovanni DalCorso Silvia Farinati Silvia Maistri Antonella Furini 2008Journal of Integrative Plant Biology2008,50,10:60
11Hydrogen Sulfide Promotes Root Organogenesis in Ipomoea batatas, Salix matsudana and Glycine max显示文摘In this report, we demonstrate that sodium hydrosulfide (NaHS), a hydrogen sulfide (H2S) donor, promoted adventitious root formation mediated by auxin and nitric oxide (NO). Application of the H2S donor to seedling cuttings of sweet potato (Ipomoea batatas L.) promoted the number and length of adventitious roots in a dose-dependent manner. It was also verified that H2S or HS- rather than other sulfur-containing components derived from NaHS could be attributed to the stimulation of adventitious root formation. A rapid increase in endogenous H2S, indole acetic acid (IAA) and NO were sequentially observed in shoot tips of sweet potato seedlings treated with HaHS. Further investigation showed that H2S-mediated root formation was alleviated by N-1-naphthylphthalamic acid (NPA), an IAA transport inhibitor, and 2-(4-carboxyphenyl)- 4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide (cPTIO), an NO scavenger. Similar phenomena in H2S donor-dependent root organogenesis were observed in both excised willow (Salix matsudana var. tortuosa Vilm) shoots and soybean (Glycine max L.) seedlings. These results indicated that the process of H2S-induced adventitious root formation was likely mediated by IAA and NO, and that H2S acts upstream of IAA and NO signal transduction pathways.Hua Zhang Jun Tang Xiao-Ping Liu Yun Wang Wei Yu Wei-Yan Peng Fang Fang Dai-Fu Ma Zhao-Jun Wei Lan-Ying Hu 2009Journal of Integrative Plant Biology2009,51,12:58
12Salicylic Acid and its Function in Plant Immunity显示文摘The small phenolic compound salicylic acid(SA) plays an important regulatory role in multiple physiological processes including plant im-mune response.Significant progress has been made during the past two decades in understanding the SA-mediated defense signaling network.Characterization of a number of genes functioning in SA biosynthesis,conjugation,accumulation,signaling,and crosstalk with other hormones such as jasmonic acid,ethylene,abscisic acid,auxin,gibberellic acid,cytokinin,brassinosteroid,and peptide hormones has sketched the finely tuned immune response network.Full understanding of the mech-anism of plant immunity will need to take advantage of fast developing genomics tools and bioinformatics techniques.However,elucidating genetic components involved in these pathways by conventional ge-netics,biochemistry,and molecular biology approaches will continue to be a major task of the community.High-throughput method for SA quantification holds the potential for isolating additional mutants related to SA-mediated defense signaling.Chuanfu An Zhonglin Mou 2011Journal of Integrative Plant Biology2011,53,6:53
13Correlations Between Foliar Stable Carbon Isotope Composition and Environmental Factors in Desert Plant Reaumuria soongorica (Pall.) Maxim.显示文摘Leaves of 407 individuals of Reaumuria soongorica (Pall.) Maxim. collected from the major distribution areas were measured to investigate the distribution characteristics of the stable carbon isotope in this desert plant, as well as correlations between δ13C values and environmental factors. Results showed that δ13C values in R. soongorica ranged from-22.77‰. to-29.85‰. and that the mean δ13C value (-26.52‰)was higher than a previously reported δ13C value for a different desert ecosystem. This indicates that R.soongorica belongs to the C3 photosynthetic pathway and has higher water use efficiency than other species. The correlations between δ13C values and environmental factors demonstrated that the foliar δ13C values in R. soongorica increased significantly with decreasing mean annual precipitation and mean relative humidity, and decreased with decreasing duration of sunshine and evaporation. The spatial distribution trend of δ13C values in R. soongorica was not obvious and there was no significant correlation between the δ13C values and mean annual temperature. We conclude that different distribution trends in δ13C values for R. soongorica were likely caused by stomatal limitation rather than by nutrient-related changes in photosynthetic efficiency and that precipitation played an important role in the wide distribution range of R.soongorica. This pattern of δ13C values for R. soongorica reinforced that it is a super-xerophil in terms of its adaptive strategies to a desert environment.Jian-Ying MA Tuo CHEN Wei-Ya QIANG Gang WANG 2005Journal of Integrative Plant Biology2005,47,9:42
14Altitudinal Pattern of Plant Species Diversity in Shennongjia Mountains, Central China显示文摘One hundred and sixty plots, approximately every 100 m above sea level (a.s.l.) along an altitudinal gradient from 470 to 3 080 m a.s.l, at the southern and northern watershed of Mt. Shennongjia,China, were examined to determine the altitudinal pattern of plant species diversity. Mt. Shennongjia was found to have high plant species diversity, with 3 479 higher plants recorded. Partial correlation analysis and detrended canonical correspondence analysis (DCCA) based on plant species diversity revealed that altitude was the main factor affecting the spatial pattern of plant species diversity on Mt. Shennongjia and that canopy coverage of the arbor layer also had a considerable effect on plant species diversity. The DCCA based on species data of importance value further revealed that altitude gradient was the primary factor shaping the spatial pattern of plant species. In addition, the rule of the 'mid-altitude bulge' was supported on Mt. Shennongjia. Plant species diversity was closely related to vegetation type and the transition zone usually had a higher diversity. Higher plant species diversity appeared in the mixed evergreen and deciduous broadleaved forest zone (900-1 500 m a.s.l.) and its transition down to evergreen broadleaved forest zone or up to deciduous broadleaved forest zone. The largest plant species diversity in whole communities on Mt. Shennongjia lay at approximately 1 200 m a.s.l. Greatest tree diversity, shrub diversity, and grass diversity was found at approximately 1 500, 1 100, and 1 200 m a.s.l., respectively. The southern watershed showed higher plant species diversity than the northern watershed, with maximum plant species diversity at a higher altitude in the southern watershed than the northern watershed. These results indicate that Mt.Shennongjia shows characteristics of a transition region. The relationship between the altitudinal pattern of plant species diversity and the vegetation type in eastern China are also discussed and a hypothesis about the altitudinal pattern of plant species diversity in eastern China is proposed.Chang-Ming ZHAO Wei-Lie CHEN Zi-Qiang TIAN Zong-Qiang XIE 2005Journal of Integrative Plant Biology2005,47,12:44

18Reproduction Diversity of Enteromorpha prolifera显示文摘Enteromorpha prolifera(Muell.) J.Agardh(Chlorophyta,Ulvophyceae),which is distributed widely in the inter-tidal zone of the ocean,is one of the most common fouling green algae.However,the present understandings of the life history of E.prolifera have been insufficient to explain their seasonal abundances.Thus it is essential to investigate how many reproductive strategies are likely to contribute to the successful colonization and flourishing of the green alga.In the present study the reproduction diversity of E.prolifera was observed and studied systematically by culturing chopped tissues.Our results showed that there are in total seven pathways of reproduction for E.prolifera including sexual,asexual and vegetative reproduction.It was indicated that the variety of the reproductive ways and the large quantity of reproductive cells produced and released during the reproductive season are the two key factors that facilitate colonization of E.prolifera.The reproduction of the alga E.prolifera mainly depends on asexual methods.The results presented here contribute to increasing our understanding about how the opportunistic macroalgae successfully maintain colonization and excessive growth.Apeng Lin Songdong Shen Jianwei Wang Binlun Yan 2008Journal of Integrative Plant Biology2008,50,5:46
19Abscisic Acid-mediated Epigenetic Processes in Plant Development and Stress Responses显示文摘Abscisic acid (ABA) regulates diverse plant processes, growth and development under non-stress conditions and plays a pivotal role in abiotic stress tolerance. Although ABA-regulated genetic processes are well known, recent discoveries reveal that epigenetic processes are an integral part of ABA-regulated processes. Epigenetic mechanisms, namely, histone modifications and cytosine DNA methylation-induced modification of genome give rise to epigenomes, which add diversity and complexity to the genome of organisms. Histone monoubiquitination appears to regulate ABA levels in developing seeds through histone H2B monoubiquitination. ABA and H2B ubiquitination dependent chromatin remodeling regulate seed dormancy. Transcription factor networks necessary for seed maturation are repressed by histone deacetylases (HDACs)-dependent and PICKLE chromatin remodeling complexes (CRCs), whereas ABA induces the expression of these genes directly or through repression of HDACs. Abiotic stress-induced ABA regulates stomatal response and stress-responsive gene expression through HDACs and HOS15-dependent histone deacetylation, as well as through the ATP-dependent SWITCH/SUCROSE NONFERMENTING CRC. ABA also probably regulates the abiotic stress response through DNA methylation and short interfering RNA pathways. Further studies on ABA-regulated epigenome will be of immense use to understand the plant development, stress adaptation and stress memory.Viswanathan Chinnusamy Zhizhong Gong Jian-Kang Zhu 2008Journal of Integrative Plant Biology2008,50,10:43
20Salt Tolerance in Soybean显示文摘Soybean is an important cash crop and its productivity is significantly hampered by salt stress. High salt imposes negative impacts on growth, nodulation, agronomy traits, seed quality and quantity, and thus reduces the yield of soybean. To cope with salt stress, soybean has developed several tolerance mechanisms, including: (i) maintenance of ion homeostasis; (ii) adjustment in response to osmotic stress; (iii) restoration of osmotic balance; and (iv) other metabolic and structural adaptations. The regulatory network for abiotic stress responses in higher plants has been studied extensively in model plants such as Arabidopsis thaliana. Some homologous components involved in salt stress responses have been identified in soybean. In this review, we tried to integrate the relevant works on soybean and proposes a working model to describe its salt stress responses at the molecular level.Tsui-Hung Phang Hon-Ming Lam 2008Journal of Integrative Plant Biology2008,50,10:42
