| 1 | Arabidopsis NF-YCs Mediate the Light-Controlled Hypocotyl Elongation via Modulating Histone Acetylation显示文摘光是支持 photomorphogenesis 的一个关键环境信号,有为植物到的一系列轻依赖者的改变的发展过程改编各种各样的外部挑战。染色质修正被建议了涉及如此的调停光的生长,但是内在的机制仍然是逃犯的。在这研究,我们识别了四 Arabidopsis thaliana 原子 Factor-YC 相当或相同的事物, NF-YC1, NF-YC3, NF-YC4,和 NF-YC9 (NF-YCs ) ,它经由 histone deacetylation 作为控制光的胚轴延伸的抑压者冗余地工作。明显的青白化显型在在轻条件下面种的 NF-YCs loss-of-function 异种幼苗被观察,包括重要伸长的胚轴和更少打开的子叶。我们发现 NF-YCs 在光与 histone deacetylase HDA15 交往,合作目标一套胚轴的倡导者延伸相关的基因,并且在联系染色质上调制 histone H4 acetylation 的层次,因此镇压基因表示。相反, NF-YC-HDA15 建筑群在黑暗中从目标基因被解除,导致 H4 acetylation 和作为结果的变白的生长的增加的水平。进一步的分析表明控制光的胚轴延伸上的 NF-YCs 的那项 transcriptional 压抑活动部分取决于 NF-YCs overexpression 的短胚轴的显型种的功能能救的 HDA15 的 HDA15,和损失的 deacetylation 活动。一起拿,我们的结果显示 NF-YC1, NF-YC3, NF-YC4,和 NF-YC9 由与 HDA15 交往在早幼苗舞台期间在 photomorphogenesis 禁止胚轴延伸作为 transcriptional 合作抑压者工作。我们 NF-YCs 能调制的调查结果热点响应经由 epigenetic 的环境暗示的植物开发规定。 | Yang Tang Xuncheng Liu Xu Liu Yuge Li Keqiang Wu Xingliang Hou | 2017 | Molecular Plant2017，10，2： | 12 |
| 2 | DELLA and EDS1 Form a Feedback Regulatory Module to Fine-Tune Plant Growth-Defense Tradeoff in Arabidopsis显示文摘Plants maintain a dynamic balance between growth and defense,and optimize allocation of resources for survival under constant pathogen infections.However,the underlying molecular regulatory mechanisms,especially in response to biotrophic bacterial infection,remain elusive.Here,we demonstrate that DELLA proteins and EDS1,an essential resistance regulator,form a central module modulating plant growth-defense tradeoffs via direct interaction.When infected by Pst DC3000,EDS1 rapidly promotes salicylic acid(SA)biosynthesis and resistance-related gene expression to prime defense response,while pathogen infection stabilizes DELLA proteins RGA and RGL3 to restrict growth in a partially EDS1-dependent manner,which facilitates plants to develop resistance to pathogens.However,the increasingly accumulated DELLAs interact with EDS1 to suppress SA overproduction and excessive resistance response.Taken together,our findings reveal a DELLA-EDS1-mediated feedback regulatory loop by which plants maintain the subtle balance between growth and defense to avoid excessive growth or defense in response to constant biotrophic pathogen attack. | Yuge Li Yuhua Yang Yilong Hu Hailun Liu Ming He Ziyin Yang Fanjiang Kong Xu Liu Xingliang Hou | 2019 | Molecular Plant2019，12，11： | 8 |
| 3 | NF-YCs modulate histone variant H2A.Z deposition to regulate photomorphogenic growth in Arabidopsis显示文摘Inplants,lightsignalstriggeraphotomorphogenic program involving transcriptome changes, epigenetic regulation, and inhibited hypocotyl elongation. The evolutionarily conserved histone variant H2 A.Z, which functions in transcriptional regulation, is deposited in chromatin by the SWI2/SNF2-RELATED 1 complex(SWR1 c). However, the role of H2 A.Z in photomorphogenesis and its deposition mechanism remain unclear. Here, we show that in Arabidopsis thaliana, H2 A.Z deposition at its target loci is induced by light irradiation via NUCLEAR FACTOR-Y, subunit C(NF-YC) proteins, thereby inhibiting photomorphogenic growth. NF-YCs physically interact with ACTIN-RELATED PROTEIN6(ARP6), a key component of the SWR1 c that is essential for depositing H2 A.Z, in a lightdependent manner. NF-YCs and ARP6 function together as negative regulators of hypocotyl growth by depositing H2 A.Z at their target genes during photomorphogenesis. Our findings reveal an important role for the histone variant H2 A.Z in photomorphogenic growth and provide insights into a novel transcription regulatory node that mediates H2 A.Z deposition to control plant growth in response to changing light conditions. | Chunyu Zhang Qian Qian Xiang Huang Wenbin Zhang Xu Liu Xingliang Hou | 2021 | Journal of Integrative Plant Biology2021，63，6： | 4 |
| 4 | FT5a interferes with the Dt1-AP1 feedback loop to control flowering time and shoot determinacy in soybean显示文摘Flowering time and stem growth habit determine inflorescence architecture in soybean, which in turn influences seed yield. Dt1, a homolog of Arabidopsis TERMINAL FLOWER 1(TFL1), is a major controller of stem growth habit, but its underlying molecular mechanisms remain unclear.Here, we demonstrate that Dt1 affects node number and plant height, as well as flowering time,in soybean under long-day conditions. The b ZIP transcription factor FDc1 physically interacts with Dt1, and the FDc1-Dt1 complex directly represses the expression of APETALA1(AP1). We propose that FT5 a inhibits Dt1 activity via a competitive interaction with FDc1 and directly upregulates AP1. Moreover, AP1 represses Dt1 expression by directly binding to the Dt1 promoter, suggesting that AP1 and Dt1 form a suppressive regulatory feedback loop to determine the fate of the shoot apical meristem. These findings provide novel insights into the roles of Dt1 and FT5 a in controlling the stem growth habit and flowering time in soybean, which determine the adaptability and grain yield of this important crop. | Lin Yue Xiaoming Li Chao Fang Liyu Chen Hui Yang Jie Yang Zhonghui Chen Haiyang Nan Linnan Chen Yuhang Zhang Haiyang Li Xingliang Hou Zhicheng Dong James LWeller Jun Abe Baohui Liu Fanjiang Kong | 2021 | Journal of Integrative Plant Biology2021，63，6： | 3 |

| 6 | Effect of inverted T arrangement on AC pollution flashover characteristics of insulator strings显示文摘The arrangement of insulator strings has an effect on its pollution flashover characteristics.A new arrangement of insulator strings,inverted T-type arrangement,is proposed in this study.The electric field distribution is simulated and the pollution flashover characteristics are tested in an artificial climate chamber.The test results indicate that the inverted T-type arrangement can greatly improve the flashover voltage of polluted insulator strings,the‘7+2’inverted T-type arrangement can increase the flashover voltage of each insulator by 8.5%on average,and the‘3+3’inverted T-type arrangement can increase the flashover voltage of each insulator by 13.4%.The discharge process is different from that of the normal suspension string when the insulator string is inverted T-shaped,i.e.a local arc is produced at the low voltage end of the insulator string and develops downward along the suspension part.While as for the horizontal tension string parts,it is difficult to generate arc during discharge development. | Xingliang Jiang Xiaodong Ren Han Wang Xingbo Han Conglai Bi Zhiyu Li Ledong Hou | 2019 | High Voltage2019，4，2： | 2 |

| 9 | Effect of the biosynthesis of the volatile compound phenylacetaldehyde on chloroplast modifications in tea (Camellia sinensis) plants显示文摘Plant volatile compounds have important physiological and ecological functions.Phenylacetaldehyde(PAld),a volatile phenylpropanoid/benzenoid,accumulates in the leaves of tea(Camellia sinensis)plants grown under continuous shading.This study was conducted to determine whether PAld production is correlated with light and to elucidate the physiological functions of PAld in tea plants.Specifically,the upstream mechanism modulating PAld biosynthesis in tea plants under different light conditions as well as the effects of PAld on chloroplast/chlorophyll were investigated.The biosynthesis of PAld was inhibited under light,whereas it was induced in darkness.The structural gene encoding aromatic amino acid aminotransferase 1(CsAAAT1)was expressed at a high level in darkness,consistent with its importance for PAld accumulation.Additionally,the results of a transcriptional activation assay and an electrophoretic mobility shift assay indicated CsAAAT1 expression was slightly activated by phytochrome-interacting factor 3-2(CsPIF3-2),which is a light-responsive transcription factor.Furthermore,PAld might promote the excitation of chlorophyll in dark-treated chloroplasts and mediate electron energy transfer in cells.However,the accumulated PAld can degrade chloroplasts and chlorophyll,with potentially detrimental effects on photosynthesis.Moreover,PAld biosynthesis is inhibited in tea leaves by red and blue light,thereby decreasing the adverse effects of PAld on chloroplasts during daytime.In conclusion,the regulated biosynthesis of PAld in tea plants under light and in darkness leads to chloroplast modifications.The results of this study have expanded our understanding of the biosynthesis and functions of volatile phenylpropanoids/benzenoids in tea leaves. | Lanting Zeng Xiaochen Zhou Xiumin Fu Yilong Hu Dachuan Gu Xingliang Hou Fang Dong Ziyin Yang | 2023 | Horticulture Research2023，10，3： | 0 |
| 10 | MAGED4B Promotes Glioma Progression via Inactivation of the TNF-α-induced Apoptotic Pathway by Down-regulating TRIM27 Expression显示文摘MAGED4B belongs to the melanoma-associated antigen family;originally found in melanoma,it is expressed in various types of cancer,and is especially enriched in glioblastoma.However,the functional role and molecular mechanisms of MAGED4B in glioma are still unclear.In this study,we found that the MAGED4B level was higher in glioma tissue than that in non-cancer tissue,and the level was positively correlated with glioma grade,tumor diameter,Ki-67 level,and patient age.The patients with higher levels had a worse prognosis than those with lower MAGED4B levels.In glioma cells,MAGED4B overexpression promoted proliferation,invasion,and migration,as well as decreasing apoptosis and the chemosensitivity to cisplatin and temozolomide.On the contrary,MAGED4B knockdown in glioma cells inhibited proliferation,invasion,and migration,as well as increasing apoptosis and the chemosensitivity to cisplatin and temozolomide.MAGED4B knockdown also inhibited the growth of gliomas implanted into the rat brain.The interaction between MAGED4B and tripartite motif-containing 27(TRIM27)in glioma cells was detected by co-immunoprecipitation assay,which showed that MAGED4B was co-localized with TRIM27.In addition,MAGED4B overexpression down-regulated the TRIM27 protein level,and this was blocked by carbobenzoxyl-L-leucyl-L-leucyl-L-leucine(MG132),an inhibitor of the proteasome.On the contrary,MAGED4B knockdown up-regulated the TRIM27 level.Furthermore,MAGED4B overexpression increased TRIM27 ubiquitination in the presence of MG132.Accordingly,MAGED4B down-regulated the protein levels of genes downstream of ubiquitin-specific protease 7(USP7)involved in the tumor necrosis factor-alpha(TNF-α)-induced apoptotic pathway.These findings indicate that MAGED4B promotes glioma growth via a TRIM27/USP7/receptor-interacting serine/threonine-protein kinase 1(RIP1)-dependent TNF-α-induced apoptotic pathway,which suggests that MAGED4B is a potential target for glioma diagnosis and treatment. | Can Liu Jun Liu Juntang Shao Cheng Huang Xingliang Dai Yujun Shen Weishu Hou Yuxian Shen Yongqiang Yu | 2023 | Neuroscience Bulletin2023，39，2： | 0 |
| 11 | Baseline susceptibility of Helicoverpa armigera,Plutella xylostella,and Spodoptera frugiperda to the meta-diamide insecticide broflanilide显示文摘Broflanilide is a novel meta-diamide insecticide that acts as a y-aminobutyric acid-gated chloride channel allosteric modulator.With its unique mode of action,broflanilide has no known cross-resistance with existing insecticides and is expected to be an effective tool for the management of insecticide resistance.Establishing the base-line susceptibility to this insecticide is an essential step for developing and implementing effective resistance management strategies.Here we evaluated the baseline susceptibil-ity to broflanilide for 3 cosmopolitan lepidopteran pest species,Helicoverpa armigera,Plutella xylostella,and Spodoptera frugiperda.Broflanilide exhibited high activity against populations sampled in the major distribution range of these pests in China,with median lethal concentrations(LCso)ranging between 0.209 and 0.684,0.076 and 0.336,and 0.075 and 0.219 mg/L for H.armigera,P xylostella,and S.frugiperda,respectively.Among-population variability in susceptibility to broflanilide was moderate for H.armigera(3.3-fold),P xylostella(4.4-fold),and S.frugiperda(2.9-fold).The recommended diagnostic concentrations for H.armigera,P xylostella,and S.frugiperda were 8,4,and 2 mg/L,re-spectively.Little or no cross-resistance to broflanilide was detected in 3 diamide-resistant strains of P xylostella and 1 spinosyns-resistant strain of S.frugiperda.Our results provide critical information for the development of effective resistance management programs to sustain efficacy of broflanilide against these key lepidopteran pests. | Xingliang Wang Tailong Shi Ping Tang Shengnan Liu Bofeng Hou Dong Jiang Jingde Lu Yihua Yang Yves Carriere Yidong Wu | 2023 | Insect Science2023，30，4： | 0 |

| 13 | Dt1 inhibits SWEET-mediated sucrose transport to regulate photoperiod-dependent seed weight in soybean显示文摘Soybean is a photoperiod-sensitive short-day crop whose reproductive period and yield are markedly affected by day-length changes.Seed weight is one of the key traits determining the soybean yield;how-ever,the prominent genes that control the final seed weight of soybean and the mechanisms underlying the photoperiod's effect on this trait remain poorly understood.In this study,we identify SwW19 as a major locus controlling soybean seed weight by QTL mapping and determine Dt1,an orthologous gene of Arabidopsis TFL1 that is known to govern the soybean growth habit,as the causal gene of the SW19 locus.We showed that Dt1 is highly expressed in developing seeds and regulates photoperiod-dependent seed weight in soybean.Further analyses revealed that the Dt1 protein physically interacts with the sucrose transporter GmSWEET10a to negatively regulate the import of sucrose from seed coat to the embryo,thus modulating seed weight under long days.However,Dt1 does not function in seed development under short days due to its very low expression.Importantly,we discovered a novel natural allelic variant of Dt1(H4 haplotype)that decouples its pleiotropic effects on seed size and growth habit;i.e.,this variant remains functional in seed development but fails to regulate the stem growth habit of soybean.Collectively,our findings provide new insights into how soybean seed development responds to photoperiod at different latitudes,offering an ideal genetic component for improving soybean's yield by manipulating its seed weightandgrowth habit. | Xiaoming Li Zhonghui Chen Haiyang Li Lin Yue Cuirong Tan Hongjie Liu Yilong Hu Yuhua Yang Xiani Yao Lingping Kong Xiang Huangi Bin Yu Chunyu Zhang Yuefeng Guan Baohui Liu Fanjiang Kong Xingliang Hou | 2024 | Molecular Plant2024，17，3： | 0 |
