| 1 | Mechanisms of Plant Responses and Adaptation to Soil Salinity显示文摘Soil salinity is a major environmental stress that restricts the growth and yield of crops.Understanding the physiological,metabolic,and biochemical responses of plants to salt stress and mining the salt tolerance-associated genetic resource in nature will be extremely important for us to cultivate salt-tolerant crops.In this review,we provide a comprehensive summary of the mechanisms of salt stress responses in plants,including salt stress-triggered physiological responses,oxidative stress,salt stress sensing and signaling pathways,organellar stress,ion homeostasis,hormonal and gene expression regulation,metabolic changes,as well as salt tolerance mechanisms in halophytes.Important questions regarding salt tolerance that need to be addressed in the future are discussed. | Chunzhao Zhao Heng Zhang Chunpeng Song Jian-Kang Zhu Sergey Shabala | 2020 | The Innovation2020，1，1： | 25 |
| 2 | Protein kinases in plant responses to drought, salt,and cold stress显示文摘Protein kinases are major players in various signal transduction pathways. Understanding the molecular mechanisms behind plant responses to biotic and abiotic stresses has become critical for developing and breeding climate-resilient crops. In this review,we summarize recent progress on understanding plant drought, salt, and cold stress responses, with a focus on signal perception and transduction by different protein kinases, especially sucrose nonfermenting1(SNF1)-related protein kinases(Sn RKs),mitogen-activated protein kinase(MAPK) cascades,calcium-dependent protein kinases(CDPKs/CPKs),and receptor-like kinases(RLKs). We also discuss future challenges in these research fields. | Xuexue Chen Yanglin Ding Yongqing Yang Chunpeng Song Baoshan Wang Shuhua Yang Yan Guo Zhizhong Gong | 2021 | Journal of Integrative Plant Biology2021，63，1： | 13 |
| 3 | Hydrogen peroxide modulates abscisic acid signaling in root growth and development in Arabidopsis显示文摘Exogenous abscisic acid(ABA)can inhibit root growth and promote formation of more root hairs in the root tip of Arabidopsis.However,the molecular mechanisms that underlie root ABA signaling are largely unknown.We report here that hydrogen peroxide(H2O2)reduces the root growth of wild type, and the phenotype of H2O2 on the root growth is similar to ABA response.Meanwhile ABA-induced changes in the morphology of root system can be partly reversed by ascorbic acid in wild type and abolished in NADPH oxidase defective mutant atrbohF and atrbohC.Further,ABA can induce H2O2 accumulation in the root cells and enhance transcription level of OXI1,which is necessary for many more AOS-dependent processes such as root hair growth in Arabidopsis.Our results suggest that H2O2 as an important signal molecule is required for the ABA-regulated root growth and development in Arabidopsis. | BAI Ling ZHOU Yun ZHANG XiaoRan SONG ChunPeng Cao MingQing | 2007 | Chinese Science Bulletin2007，52，8： | 12 |
| 4 | Identification and primary genetic analysis of Arabidopsis stomatal mutants in response to multiple stresses显示文摘In response to variable environmental conditions, guard cells located in the leaf epidermis can integrate and cope with a multitude of complicated stimuli, thereby making stomata in an appro- priate state. However, many signaling components in guard cell signaling remain elusive. In our laboratory, a tool for non-invasive remote infrared thermal images was used to screen an ethyl methane sulfonate-mutagenized population for Arabidopsis stomatal response mutants under multiple stresses (ABA, H2O2, CO2, etc.). More than forty 'hot' or 'cold' mutants were isolated (above or below 0.5℃ in con- trast to normal plantlets). Identification and primary genetic analysis of these mutants show that they are monogenic recessive mutations and there exist distinct difference in stomata apertures compared to wild type. These mutants in response to various environmental stresses and hormones were comprehen- sively investigated, which enables us to further un- derstand the cross-talk in different signal transduction pathways. | SONG Yuwei KANG Yanli LIU Hao ZHAO Xiaoliang WANG Pengtao AN Guoyong ZHOU Yun MIAO Chen SONG Chunpeng | 2006 | Chinese Science Bulletin2006，51，21： | 11 |
| 5 | MAP kinase specifically mediates the ABA-induced H_2O_2 generation in guard cells of Vicia faba L.显示文摘Mitogen-activated protein (MAP) kinase is involved in ABA- or H2O2-signaling, and H2O2 acts as inter-mediate in the downstream of ABA signal transduction pathway, which has recently emerged as a secondary mes-senger of ABA signaling. Using an epidermal strip bioassay and laser scanning confocal microscope, we provided the first evidence that MAP kinase plays an important role in H2O2 signal initial, amplification and specific targeting in response to stimuli in guard cells. ABA- or H2O2-induced Vicia faba stomatal closure was inhibited or reversed by the specific inhibitor PD98059 of MEK1/2; the guard cells were pre-incubated or -microinjected by 10 mmol·L-1 PD98059, ABA could not enhance the fluorescence intensity of H2O2 probe dichlorofluorescein (DCF). Meanwhile, after ABA induced the H2O2 accumulation in guard cells, the exogenous or intracellular PD98059 could reduce the DCF fluorescence intensity. Most interestingly, on the contrary to ABA, the DCF fluorescence intensity of guard cells treated by 100 mmol·L-1 salicylic acid (SA) was not down-regulated by PD98059, yet PD98059 did not regulate the stomatal move-ment being induced by light, dark or salicylic acid. These results suggest that MEK1/2 could mediate stomatal closure by abolishing the ABA-induced H2O2 generation/accumula- tion in the specific manner. | JIANG Jing1,2, AN Guoyong1, WANG Pengcheng1, WANG Pengtao1, HAN Jinfeng2, JIA Yanbin1 & SONG Chunpeng1 1.

| 6 | Functional analysis of the ABA-responsive protein family in ABA and stress signal transduction in Arabidopsis显示文摘The phytohormone abscisic acid(ABA)plays an important role in plant growth and development,for example in seed dormancy and germination,as well as in plant responses to environmental stresses,such as drought and high salinity.Previous studies have shown that ABA regulates the expression of genes with an ABA-responsive element(ABRE)and their corresponding physiological responses.Bioinformatics analysis identified a GRAM domain-containing gene family that has a multiple ABRE cis-element,which was termed the ABA-responsive protein(ABR)family.To analyze the function of the ABR family,we identified homozygous T-DNA insertion mutants and constructed abr1,2,3 double mutants and triple mutant.The abr1,abr2 and abr3single mutants showed a normal phenotype;however,the germination of seeds of the double mutants and triple mutant were insensitive to ABA,NaCl,mannitol and glucose.ABR1-GFP was distributed as a punctate structure in the cytosol and may be localized in the endomembrane system.The ABR2-GFP and ABR3-GFP proteins localized in the cytoplasm.In addition,ABR1,ABR2 and ABR3 were expressed in various tissues,and could be induced by several abiotic stresses,especially by ABA.The expressions of these genes were significantly suppressed in aba2,abi1 and abi2 null mutants.These results suggested that the ABR family may act downstream of ABI1 and ABI2 in the ABA signal transduction process in plants. | LIU LingYun LI Na YAO ChunPeng MENG SaSa SONG ChunPeng | 2013 | Chinese Science Bulletin2013，58，31： | 7 |
| 7 | Arabidopsis calcium-dependent protein kinase CPK28 is potentially involved in the response to osmotic stress显示文摘As calcium sensors, plant calcium-dependent protein kinases(CDPKs) play important roles in plants' responses to various abiotic stresses. Here, we report the functional characterization of CPK28, a member of the CDPK family in Arabidopsis, in response to osmotic stress.The cpk28 mutant, a loss-of-function mutant, exhibited an NaCl- and mannitol-sensitive phenotype in green cotyledons, while CPK28-overexpressing plants displayed stronger tolerance to NaCl and mannitol stresses than wildtype plants. Reverse transcriptase-polymerase chain reaction and beta-glucuronidase staining assays showed that NaCl and mannitol stresses induced CPK28. CPK28-overexpressing lines accumulated significantly more proline relative to wild-type plants and mutant plants under NaCl and mannitol stresses. Transient expression of CPK28-GFP in mesophyll cell protoplasts, as well as stable transgenic lines expressing CPK28-GFP, showed that CPK28 was localized in the plasma membrane. Expression levels of known stress-responsive genes were not significantly altered in the null mutant and overexpression lines,suggesting that CPK28 possibly mediated the stress response via the regulation of target proteins rather than via regulation at the level of transcription. Meanwhile, CPK28could autophosphorylate. Taken together, these data demonstrated that CPK28, a potential positive regulator, is involved in the response to osmotic stress in Arabidopsis. | Anli Gao Qingyang Wu Yu Zhang Yuchen Miao Chunpeng Song | 2014 | Chinese Science Bulletin2014，59，11： | 5 |
| 8 | Reciprocal regulation between the negative regulator PP2CG1 phosphatase and the positive regulator OST1 kinase confers cold response in Arabidopsis显示文摘Protein phosphorylation and dephosphorylation have been reported to play important roles in plant cold responses.In addition,phospho-regulatory feedback is a conserved mechanism for biological processes and stress responses in animals and plants.However,it is less well known that a regulatory feedback loop is formed by the protein kinase and the protein phosphatase in plant responses to cold stress.Here,we report that OPEN STOMATA 1(OST1)and PROTEIN PHOSPHATASE 2C G GROUP 1(PP2CG1)reciprocally regulate the activity during the cold stress response.The interaction of PP2CG1 and OST1 is inhibited by cold stress,which results in the release of OST1 at the cytoplasm and nucleus from suppression by PP2CG1.Interestingly,cold-activated OST1 phosphorylates PP2CG1 to suppress its phosphatase activity,thereby amplifying cold signaling in plants.Mutations of PP2CG1 and its homolog PP2CG2 enhance freezing tolerance,whereas overexpression of PP2CG1 decreases freezing tolerance.Moreover,PP2CG1 negatively regulates protein levels of C-REPEAT BINDING FACTORs(CBFs)under cold stress.Our results uncover a phosphor/dephosphor-regulatory feedback loop mediated by PP2CG1 phosphatase and OST1 protein kinase in plant cold responses. | Jian Lv Jingyan Liu Yuhang Ming Yiting Shi Chunpeng Song Zhizhong Gong Shuhua Yang Yanglin Ding | 2021 | Journal of Integrative Plant Biology2021，63，8： | 2 |
| 9 | Arabidopsis U-box E3 ubiquitin ligase PUB11 negatively regulates drought tolerance by degrading the receptor-like protein kinases LRR1 and KIN7显示文摘Both plant receptor-like protein kinases(RLKs)and ubiquitin-mediated proteolysis play crucial roles in plant responses to drought stress.However,the mechanism by which E3 ubiquitin ligases modulate RLKs is poorly understood.In this study,we showed that Arabidopsis PLANT U-BOX PROTEIN 11(PUB11),an E3 ubiquitin ligase,negatively regulates abscisic acid(ABA)-mediated drought responses.PUB11 interacts with and ubiquitinates two receptor-like protein kinases,LEUCINE RICH REPEAT PROTEIN 1(LRR1)and KINASE 7(KIN7),and mediates their degradation during plant responses to drought stress in vitro and in vivo.pub11 mutants were more tolerant,whereas Irr1 and kin7 mutants were more sensitive,to drought stress than the wild type.Genetic analyses show that the pub11 Irr1 kin7 triple mutant exhibited similar drought sensitivity as the Irr1 kin7 double mutant,placing PUB11 upstream of the two RLKs.Abscisic acid and drought treatment promoted the accumulation of PUB11,which likely accelerates LRR1 and KIN7 degradation.Together,our results reveal that PUB11 negatively regulates plant responses to drought stress by destabilizing the LRR1 and KIN7 RLKs. | Xuexue Chen Tingting Wang Amin Ur Rehman Yu Wang Junsheng Qi Zhen Li Chunpeng Song Baoshan Wang Shuhua Yang Zhizhong Gong | 2021 | Journal of Integrative Plant Biology2021，63，3： | 2 |
| 10 | Osmotically stress-regulated the expression of glutathione peroxidase 3 in Arabidopsis显示文摘Gene expression of glutathione peroxidase 3 (ATGPX3) in response to osmotic stress was analyzed in Arabidopsis using ATGPX3 promoter-glucuronidase (GUS) transgenic plants. High levels of GUS ex- pression were detected under osmotic stress in ATGPX3 promoter-GUS transgenic plants. Compared with the wild type, the growth and development of ATGPX3 mutants (atgpx3-1) were more sensitive to mannitol. In addition, the expression of RD29A, ABI1, ABI2 and RbohD in atgpx3-1 was induced by ABA stress. These results suggest that ATGPX3 might be involved in the signal transduction of osmotic stress. | MIAO YuChen GUO JingGong LIU ErTao LI Kun DAI Jie WANG PengCheng CHEN Jia SONG ChunPeng | 2007 | Chinese Science Bulletin2007，52，1： | 1 |

| 12 | RAF22,ABI1 and OST1 form a dynamic interactive network that optimizes plant growth and responses to drought stress in Arabidopsis显示文摘Plants adapt to their ever-changing environment via positive and negative signals induced by environmental stimuli.Drought stress,for instance,induces accumulation of the plant hormone abscisic acid(ABA),triggering ABA signal transduction.However,the molecular mechanisms for switching between plant growth promotion and stress response remain poorly understood.Here we report that RAF(rapidly accelerated fibrosarcoma)-LIKE MITOGEN-ACTIVATED PROTEIN KINASE KINASE KINASE 22(RAF22)in Arabidopsis tha/iana physically interacts with ABA INSENSITIVE 1(ABl1)and phosphorylates ABl1 at Ser416 residue to enhance its phosphatase activity.Interestingly,ABl1 can also enhance the activity of RAF22 through dephosphorylation,reciprocally inhibiting ABA signaling and promoting the maintenance of plant growth under normal conditions.Under drought stress,however,the ASA-activated OPEN STOMATA1(OST1)phosphorylates the Ser81 residue of RAF22 and inhibits its kinase activity,restraining its enhancement of ABl1 activity.Taken together,our study reveals that RAF22,ABl1,and OST1 form a dynamic regulatory network that plays crucial roles in optimizing plant growth and environmental adaptation under drought stress. | Zhihui Sun Zhenkai Feng Yanglin Ding Yuanpeng Qi Shan Jiang Zhen Li Yu Wang Junsheng Qi Chunpeng Song Shuhua Yang Zhizhong Gong | 2022 | Molecular Plant2022，15，7： | 1 |
| 13 | BAK1 plays contrasting roles in regulating abscisic acid-induced stomatal closure and abscisic acid-inhibited primary root growth in Arabidopsis显示文摘The mechanisms that balance plant growth and stress responses are poorly understood, but they appear to involve abscisic acid(ABA) signaling mediated by protein kinases. Here, to explore these mechanisms, we examined the responses of Arabidopsis thaliana protein kinase mutants to ABA treatment. We found that mutants of BRASSINOSTEROID INSENSITIVE 1-ASSOCIATED RECEPTOR KINASE 1(BAK1) were hypersensitive to the effects of ABA on both seed germination and primary root growth. The kinase OPEN STOMATA 1(OST1) was more highly activated by ABA in bak1 mutant than the wild type. BAK1 was not activated by ABA treatment in the dominant negative mutant abi1-1 or the pyr1 pyl4 pyl5 pyl8 quadruple mutant, but it was more highly activated by this treatment in the abi1-2 abi2-2 hab1-1 loss-of-function triple mutant than the wild type. BAK1 phosphorylates OST1 T146 and inhibits its activity. Genetic analyses suggested that BAK1 acts at or upstream of core components in the ABA signaling pathway, including PYLs, PP2 Cs,and Sn RK2 s, during seed germination and primary root growth. Although the upstream brassinosteroid(BR) signaling components BAK1 and BR INSENSITIVE 1(BRI1) positively regulate ABAinduced stomatal closure, mutations affecting downstream components of BR signaling, including BRASSINOSTEROID-SIGNALING KINASEs(BSKs)and BRASSINOSTEROID-INSENSITIVE 2(BIN2), did not affect ABA-mediated stomatal movement. Thus,our study uncovered an important role of BAK1 in negatively regulating ABA signaling during seed germination and primary root growth, but positively modulating ABA-induced stomatal closure, thus optimizing the plant growth under drought stress. | Jinping Deng Lingyao Kong Yinhua Zhu Dan Pei Xuexue Chen Yu Wang Junsheng Qi Chunpeng Song Shuhua Yang Zhizhong Gong | 2022 | Journal of Integrative Plant Biology2022，64，6： | 1 |
| 14 | Effect of internal defects on tensile strength in SLM additively-manufactured aluminum alloys by simulation显示文摘This research investigates the effect of internal defects on the tensile strength of Selective Laser Melting(SLM)additively-manufactured aluminum alloy(AlSi10Mg)test parts used for civil aircraft light weight design.A Finite Element Analysis(FEA)model containing internal defects was established by combining test data and the stress concentration factor comparison method.The effect of variation in the number,location and shape of defects on the finite element results was analyzed.Its results show that it is reasonable to use spherical defect modeling.The finite element modeling and analysis methods are also applied to the study of the effect of internal defects on tensile strength in additive manufacturing of other metallic materials.According to the FEA results of single defects at different scales,the formula for calculating the weakening degree of tensile strength applicable to the defective area of less than 15%was established.The result of the procedure is reliable and conservative.This research results can guide the selection of process parameters for the additive manufacturing of aluminum alloys.Further,the research results can promote the application of metal additive manufacturing in designing light-weight civil aircraft structures. | Xin SONG Bowen FU Xin CHEN Jiazhen ZHANG Tong LIU Chunpeng YANG Yifan YE | 2023 | Chinese Journal of Aeronautics2023，36，10： | 1 |
| 15 | Strong and Superhydrophobic Wood with Aligned Cellulose Nanofibers as a Waterproof Structural Material显示文摘Lightweight structural materials are important for the energy efficiency of applications,particularly those in the building sector.Here,inspired by nature,we developed a strong,superhydrophobic,yet lightweight material by simple in situ growth of nano-SiO2 and subsequent densification of the wood substrate.In situ generation of SiO2 nanoparticles both inside the wood channels and on the wood surfaces gives the material superhydrophobicity,with static and dynamic contact angles of 159.4°and 3°,respectively.Densification of the wood to remove most of the spaces among the lumen and cell walls results in a laminated,dense structure,with aligned cellulose nanofibers,which in turn contributes to a high mechanical strength up to 384.2 MPa(7-times higher than natural wood).Such treatment enables the strong and superhydrophobic wood(SH-Wood)to be stable and have excellent water,acid,and alkaline resistance.The high mechanical strength of SH-Wood combined with its excellent structural stability in harsh environments,as well its low density,positions the strong and superhydrophobic wood as a promising candidate for strong,lightweight,and durable structural materials that could potentially replace steel. | Yongfeng Li Chaoji Chen Jianwei Song Chunpeng Yang Yudi Kuang Azhar Vellore Emily Hitz Mingwei Zhu Feng Jiang Yonggang Yao Amy Gong Ashlie Martini Liangbing Hu | 2020 | Chinese Journal of Chemistry2020，38，8： | 1 |

| 18 | Generation of the genetic mutant population for the screening and characterization of the mutants in response to drought in maize显示文摘The autonomous Mutator(Mu)transposon in maize(Zea mays L.)lines 115F,330I,and 715D were crossed with inbred lines B73,Mo17,97108,and H9-21,M1were self-pollinated to establish the Mu insertion-mutagenized M2seeds pool and The M2plants encompassed a large amount of biological variation relevant to improving agronomy traits by observed in the field.Next we statistically analyzed these candidate mutants.Under drought stress,we screened seedlings at 3-leaf stage by using the infrared thermography,and successfully got 108 droughtinsensitive and 121 drought-sensitive candidate mutants from more than 38,000 lines,which temperature were significant different with others.These candidate mutants were primarily analyzed by infrared thermography,chlorophyll fluorescence,leaf water losing,photosynthetic characteristics,content of soluble sugars,soluble protein,and proline assay.The selected mutants were cloned by MuTAIL–PCR methods.Here we provide the better genetic materials for research on maize breeding for drought tolerance. | Zhiyong Gao Hao Liu Hongliang Wang Ning Li Daojie Wang Yuwei Song Yuchen Miao Chunpeng Song | 2014 | Chinese Science Bulletin2014，59，8： | 1 |
| 19 | Large-area gold nanohole arrays fabricated by one-step method for surface plasmon resonance biochemical sensing显示文摘Surface plasmon resonance(SPR) nanosensors based on metallic nanohole arrays have been widely reported to detect binding interactions in biological specimens. A simple and effective method for constructing nanoscale arrays is essential for the development of SPR nanosensors. In this work, we report a one-step method to fabricate nanohole arrays by thermal nanoimprinting in the matrix of IPS(Intermediate Polymer Stamp). No additional etching process or supporting substrate is required. The preparation process is simple, time-saving and compatible for roll-to-roll process, potentially allowing mass production. Moreover, the nanohole arrays were integrated into detection platform as SPR sensors to investigate different types of biological binding interactions. The results demonstrate that our one-step method can be used to efficiently fabricate large-area and uniform nanohole arrays for biochemical sensing. | Huijie Qi Lihong Niu Jie Zhang Jian Chen Shujie Wang Jingjing Yang Siyi Guo Tom Lawson Bingyang Shi Chunpeng Song | 2018 | Science China(Life Sciences)2018，61，4： | 0 |
