| 1 | Hydrogen sulfide regulates abiotic stress tolerance and biotic stress resistance in Arabidopsis显示文摘Hydrogen sulfide(H_2S) is an important gaseous molecule in various plant developmental processes and plant stress responses.In this study,the transgenic Arabidopsis thaliana plants with modulated expressions of two cysteine desulfhydrases,and exogenous H_2S donor(sodium hydrosulfide,NaHS) and H_2S scavenger(hypotaurine,HT) pre-treated plants were used to dissect the involvement of H_2S in plant stress responses.The cysteine desulfhydrases overexpressing plants and NaHS pre-treated plants exhibited higher endogenous H_2S level and improved abiotic stress tolerance and biotic stress resistance,while cysteine desulfhydrases knockdown plants and HT pre-treated plants displayed lower endogenous H_2S level and decreased stress resistance.Moreover,H_2S upregulated the transcripts of multiple abiotic and biotic stress-related genes,and inhibited reactive oxygen species(ROS) accumulation.Interestingly,MIR393-mediated auxin signaling including MIR393a/b and their target genes(TIR1,AFB1,AFB2,and AFB3) was transcriptionally regulated by H_2S,and was related with H_2S-induced antibacterial resistance.Moreover,H_2S regulated 50 carbon metabolites including amino acids,organic acids,sugars,sugar alcohols,and aromatic amines.Taken together,these results indicated that cysteine desulfhydrase and H_2S conferred abiotic stress tolerance and biotic stress resistance,via affecting the stress-related gene expressions,ROS metabolism,metabolic homeostasis,and MIR393-targeted auxin receptors. | Haitao Shi Tiantian Ye Ning Han Hongwu Bian Xiaodong Liu Zhulong Chan | 2015 | Journal of Integrative Plant Biology2015，57，7： | 26 |
| 2 | Comparative proteomic and metabolomic analyses reveal mechanisms of improved cold stress tolerance in bermudagrass (Cynodon dactylon(L.) Pers.) by exogenous calcium显示文摘As an important second messenger, calcium is involved in plant cold stress response, including chilling(<20 °C) and freezing(<0 °C). In this study, exogenous application of calcium chloride(CaCl2) improved both chilling and freezing stress tolerances, while ethylene glycol‐bis‐(b‐aminoethyl) ether‐N,N,N,N‐tetraacetic acid(EGTA) reversed CaCl2 effects in bermudagrass(Cynodon dactylon(L.) Pers.).Pysiological analyses showed that CaCl2 treatment alleviated the reactive oxygen species(ROS) burst and cell damage triggered by chilling stress, via activating antioxidant enzymes,non‐enzymatic glutathione antioxidant pool, while EGTA treatment had the opposite effects. Additionally, comparative proteomic analysis identified 51 differentially expressed proteins that were enriched in redox, tricarboxylicacid cycle,glycolysis, photosynthesis, oxidative pentose phosphate pathway, and amino acid metabolisms. Consistently, 42 metabolites including amino acids, organic acids, sugars, and sugar alcohols were regulated by CaCl2 treatment under control and cold stress conditions, further confirming the Researchcommon modulation of CaCl2 treatment in carbon metabolites and amino acid metabolism. Taken together, this study reported first evidence of the essential and protective roles of endogenous and exogenous calcium in bermudagrass response to cold stress, partially via activation of the antioxidants and modulation of several differentially expressed proteins and metabolic homeostasis in the process of cold acclimation. | Haitao Shi Tiantian Ye Bao Zhong Xun Liu Zhulong Chan | 2014 | Journal of Integrative Plant Biology2014，56，11： | 19 |
| 3 | Development of highway constructing technology in the permafrost region on the Qinghai-Tibet plateau显示文摘The Qinghai-Tibet Highway passes through the Qinghai-Tibet plateau hinterland from north to south, from Kunlun Mountain to Tanggula Mountain. The average altitude is above 4500 m and permafrost covers more than 700 km length of area with high elevation and high temperature. The climate of the plateau is capricious and the surroundings along the road are bad, where the mean annual atmosphere temperature is -2 to -7℃ and the oxygen content is inadequate, which is less than 50% of the sea level, while the solar radiation is higher than 3600 kJ/m2. The basic characteristics of the plateau surroundings are the permafrost, coldness with litter oxygen, and fragile ecosystem. As the air temperature warms all over the world, the permafrost on the plateau responds quickly. The average temperature of permafrost is up by 0.2―0.3℃ in recent 20 years, and the island-permafrost dwindles with a high rate, and the high temperature permafrost degrades quickly, and the temperature of the low temperature permafrost increases remarkably. These gradually cause the highway engineering diseases in the permafrost region. The Qinghai-Tibet highway has experienced much maintenance and rebuilding for 50 years after it was built, and the continual observation and investigation have been made for more than 30 years. This road is the longest test engineering for permafrost research work in China. It is no doubt that it is also the greatest engineering project in plateau permafrost region. The Ministry of Communication in China initiated the research project 'Research on a series of technologies for highway constructing in the permafrost regions' in 2002, which was to meet the challenges from the effect of climatic warming on the permafrost. The project systematically studied the permafrost engineering theories, methods for survey and design, engineering stabilization measures, preventing of the road disasters and maintaining, environment protection and the techniques to prolong the road engineering life in the cold surroundings with high altitude and less oxygen. This article describes a series of technologies for highway constructing according to the special surroundings in the plateau, including some innovative achievements and the research and development of permafrost engineering. | WANG ShuangJie CHEN JianBing ZHANG JinZhao LI ZhuLong | 2009 | Science China(Technological Sciences)2009，52，2： | 16 |
| 4 | Improvement of plant abiotic stress tolerance through modulation of the polyamine pathway显示文摘Polyamines(mainly putrescine(Put),spermidine(Spd),and spermine(Spm))have been widely found in a range of physiological processes and in almost all diverse environmental stresses.In various plant species,abiotic stresses modulated the accumulation of polyamines and related gene expression.Studies using loss-of-function mutants and transgenic overexpression plants modulating polyamine metabolic pathways confirmed protective roles of polyamines during plant abiotic stress responses,and indicated the possibility to improve plant tolerance through genetic manipulation of the polyamine pathway.Additionally,putative mechanisms of polyamines involved in plant abiotic stress tolerance were thoroughly discussed and crosstalks among polyamine,abscisic acid,and nitric oxide in plant responses to abiotic stress were emphasized.Special attention was paid to the interaction between polyamine and reactive oxygen species,ion channels,amino acid and carbon metabolism,and other adaptive responses.Further studies are needed to elucidate the polyamine signaling pathway,especially polyamine-regulated downstream targets and the connections between polyamines and other stress responsive molecules. | Haitao Shi Zhulong Chan | 2014 | Journal of Integrative Plant Biology2014，56，2： | 13 |

| 11 | APPLICATION OF CATIONIC POLYMERIC MICROPARTICLES ON RETENTION AND DRAINAGE显示文摘The conditions of preparation and performance of a new structure of cationic organic polymeric micropaticles (CPMP) mainly composed of styrene and DADMAC were studied. And its application on retention and drainage on bleached hardwood pulp was investigated and compared with that of APAM and CPAM. The results show that the retention and drainage of CPMP on pulp is in positive proportion to the rise of the potential of the solution, and the first-pass retention ratio of bleached hardwood pulp goes up with the increase of the CPMP content. The functions of CPMP and CPAM are affected less by the shear force and the pH value of the system compared to that of APAM, and effect on retention of CPMP3 is appropriate to that of CPAM, but superior to that of APAM. | ZhuLong DuoxianSun JianjuaLi HuaiyuZhan | 2004 | 天津科技大学学报2004，19，A01： | 0 |
| 12 | Arabidopsis PED_2 positively modulates plant drought stress resistance显示文摘Abscisic acid(ABA) is an important phytohormone that functions in seed germination,plant development,and multiple stress responses.Arabidopsis Peroxisome defective 2(AtPED2)(also known as AtPEXOX/N14,AtPEX14),is involved in the intracellular transport of thiolase from the cytosol to glyoxysomes,and perosisomal matrix protein import in plants.In this study,we assigned a new role for AtPED2in drought stress resistance.The transcript level of AtPED2was downregulated by ABA and abiotic stress treatments.AtPED2 knockout mutants were insensitive to ABA-mediated seed germination,primary root elongation,and stomatal response,while AtPED2 over-expressing plants were sensitive to ABA in comparison to wide type(WT).AtPED2 also positively regulated drought stress resistance,as evidenced by the changes of water loss rate,electrolyte leakage,and survival rate.Notably,AtPED2 positively modulated expression of several stress-responsive genes(RAB18,RD22,RD29 A,and RD29B),positively affected underlying antioxidant enzyme activities and negatively regulated reactive oxygen species(ROS) level under drought stress conditions.Moreover,multiple carbon metabolites including amino acids,organic acids,sugars,sugar alcohols,and aromatic amines were also positively regulated by AtPED2.Taken together,these results indicated a positive role for AtPED2 in drought resistance,through modulation of stress-responsive genes expression,ROS metabolism,and metabolic homeostasis,at least partially. | Haitao Shi Tiantian Ye Fan Yang Zhulong Chan | 2015 | Journal of Integrative Plant Biology2015，57，9： | 0 |
