| 3 | Genome-Wide Identification of Zn_(2)Cys_(6 ) Class Fungal-Specific Transcription Factors(ZnFTFs)and Functional Analysis of UvZnFTFI in Ustilaginoidea virens显示文摘Transcription factors(TFs)orchestrate the regulation of cellular gene expression and thereby determine cell functionality.In this study,we analyzed the distribution of TFs containing domains,which named as ZnFTFs,both in ascomycete and basidiomycete fungi.We found that ZnFTFs were widely distributed in these fungal species,but there was more expansion of the ZnFTF class in Ascomycota than Basidiomycota.We identified 40 ZnFTFs in Ustilaginoidea virens,and demonstrated the involvement of UvZnFTF1 in vegetative growth,conidiation,pigment biosynthesis and pathogenicity.RNA-Seq analysis suggested that UvZnFTF1 may regulate different nutrient metabolism pathways,the production of secondary metabolites,and the expression of pathogen-host interaction genes and secreted protein-encodi ng genes.Analysis of the distributi on of differe nt fungal TFs in U.virens further dem on strated that UvZnFTFs make up a large TF family and may play essential biological roles in U.virens. | SONG Tianqiao ZHANG Xiong ZHANG You LIANG Dong YAN Jiaoling YU Junjie YU Mina CAO Huijuan YONG Mingli PAN Xiayan QI Zhongqiang DU Yan ZHANG Rongsheng LIU Yongfeng | 2021 | Rice science2021，28，6： | 4 |
| 4 | 高效、快速提取高质量稻曲病菌基因组DNA方法显示文摘稻曲病菌[Ustilaginoidea virens(Cooke)Takahashi]培养期间菌丝生长缓慢,且产生大量次生代谢产物,严重影响提取稻曲病菌基因组DNA质量与效率。将一步式提取法(Rapid one-step extraction,ROSE)增加异丙醇、NaAc冷冻沉淀DNA和70%无水乙醇漂洗DNA两个步骤,建立一种高效、快速提取高质量稻曲病菌基因组DNA的方法,即改良ROSE法,并将该方法与稻曲病菌基因组DNA传统提取方法(CTAB法、SDS法、试剂盒法和改良脲素法)在提取步骤、DNA纯度与得率、PCR反应和酶切效率等方面加以比较。结果表明,5种方法均得到稻曲病菌基因组DNA,但改良ROSE法同时具有无毒、环保、低成本、快速获取高质量DNA的优点。改良ROSE法s可用于稻曲病菌分子标记、遗传图谱构建等需短时间内快速获取DNA的分子试验研究,也适用于稻曲病菌基因精细定位、克隆和测序等需高质量DNA的分子试验。 | 张俊华 马玥 杨明秀 宋爽 刘连夫 杨硕 | 2020 | 东北农业大学学报2020，51，3： | 2 |
| 5 | Comprehensive identification of lysine 2-hydroxyisobutyrylated proteins in Ustilaginoidea virens reveals the involvement of lysine 2-hydroxyisobutyrylation in fungal virulence显示文摘Lysine 2-hydroxyisobutyrylation(Khib) is a newly identified post-translational modification(PTM) that plays important roles in transcription and cell proliferation in eukaryotes. However, its function remains unknown in phytopathogenic fungi. Here,we performed a comprehensive assessment of Khibin the rice false smut fungus Ustilaginoidea virens, using Tandem Mass Tag(TMT)-based quantitative proteomics approach. A total of 3 426 Khibsites were identified in 977 proteins, sugg esting that Khibis a common and complex PTM in U. virens. Our data demonstrated that the2-hydroxyisobutyrylated proteins are involved in diverse biological processes. Network analysis of the modified proteins revealed a highly interconnected protein network that included many well-studied virulence factors. We confirmed that the Zn-binding reduced potassium dependency3-type histone deacetylase(UvRpd3) is a major enzyme that removes 2-hydroxyisobutyrylation and acetylation in U. virens. Notably, mutations of Khib sites in the mitogen-activated protein kinase(MAPK)UvSlt2 significantly reduced fungal virulence and decreased the enzymatic activity of UvSlt2. Molecular dynamics simulations demonstrated that 2-hydroxyisobutyrylation in UvSlt2 increased the hydrophobic solvent-accessible surface area and thereby affected binding between the UvSlt2 enzyme and its substrates. Our findings thus establish Khibas a major post-translational modification in U. virens and point to an important role for Khibin the virulence of this phytopathogenic fungus. | Xiaoyang Chen Xiabing Li Pingping Li Xiaolin Chen Hao Liu Junbin Huang Chaoxi Luo Tom Hsiang Lu Zheng | 2021 | Journal of Integrative Plant Biology2021，63，2： | 2 |
| 6 | Putative Phosphatase UvPsr1 Is Required for Mycelial Growth, Conidiation, Stress Response and Pathogenicity in Ustilaginonidea virens显示文摘Ustilaginoidea virens is the causal agent of rice false smut,which can be a highly destructive disease of rice.The plasma membrane phosphatase Psr1 proteins,which act as a regulator of the salinity stress response in yeast,are widely distributed across fungi,but their functional characterization is sketchy.In this study,we characterized the functions of Psr1 protein,UvPsr1,in U.virens.Analyses of the AUvpsr1 and its complementation strain showed that UvPsr1 is required for normal mycelial growth,conidiation and tolerance to oxidative,osmotic and cell wall stresses.When rice panicles were inoculated with the AUvpsr1 strains,no symptoms of false smut disease developed,showing that UvPSR1 also contributes to the pathogenicity of the fungus.The deletion mutant of UvPSR1 also appeared to produce a smaller titer of toxic compounds able to inhibit elongation of the germinated seeds.In conclusion,our results indicated that UvPsr1 is a new pathogenic factor of U.virens. | Xiong Meng Meng Shuai Qiu Jiehua Shi Huanbin Shen Xiangling Kou Yanjun | 2020 | Rice science2020，27，6： | 2 |

| 8 | 稻曲病菌转录因子UvZnFTF2参与稻曲病菌生长发育和致病性显示文摘转录因子通过调控生物体内不同基因的转录进而调控机体的生物学功能。ZnFTFs(Zn2Cys6class fungal-specific transcription factors)家族转录因子具有Zn_clus结构域和fungal_trans结构域,是一类真菌特异性转录因子。关于该转录因子在稻曲病菌中的作用及其机制报道较少。本研究分析了包含一个Zn_clus结构域和fungal_trans结构域的UvZnFTF2转录因子在稻曲病菌侵染不同时间点的转录表达模式,结果表明,在侵染3 d后,UvZnFTF2的表达开始上升,侵染7 d后下降。通过生物信息学分析发现,UvZnFTF2进化上与蝗缘殭菌(Metarhizium acridum)的ZnFTF2(KAG8424307.1)同源性最高。通过在稻曲病菌中沉默UvZnFTF2进行功能研究发现,UvZnFTF2沉默后,稻曲病菌菌丝生长和产孢量显著降低,并且致病性显著下降。RT-PCR分析表明,沉默UvZnFTF2后稻曲病菌中效应子SGP1的转录表达量显著低于野生型菌株。上述结果揭示了UvZnFTF2对稻曲病菌生长、发育和致病性的重要作用,为深入揭示稻曲病菌生长发育和致病分子机制奠定基础。 | 宋天巧 于俊杰 俞咪娜 曹慧娟 潘夏艳 齐中强 杜艳 梁栋 张荣胜 刘永锋 | 2022 | 植物病理学报2022，52，6： | 1 |
| 9 | 玉米蛋白粉DNA提取方法比较研究显示文摘饲料样本本身的复杂性给进出口产品转基因(genetically modified,GM)成分的检测工作带来了巨大的压力和挑战。玉米蛋白粉主要包含蛋白质、淀粉和脂类等成分,从中提取高品质的DNA比较困难,而高品质的DNA是转基因检测研究的关键,能够大大降低进出口检验中的“假阴性”结果。采用市售主流品牌常用的7种试剂盒(Promega公司、Biotecon公司、天根生化科技有限公司、Invitrogen公司、Qiagen公司、TaKaRa公司)、CTAB法以及改良SDS-CTAB法提取玉米蛋白粉中的DNA。通过对玉米内源基因进行实时荧光PCR检测,发现改良SDS-CTAB法提取的玉米蛋白粉DNA质量明显优于其他方法,改良SDS-CTAB法内源基因zSSⅡb的Ct值为28.14,较CTAB法提高了27%。研究建立的改良SDS-CTAB法在国内外尚属首次应用于饲料转基因产品中,并对7批次实验室送检样品进行转基因成分检测,成功检出2批次阳性样品。 | 甄珍 窦迎港 刘晓兰 | 2022 | 生物技术进展2022，12，1： | 1 |
| 10 | Ustilaginoidea virens modulates lysine 2-hydroxyisobutyrylation in rice flowers during infection显示文摘The post-translational modification lysine 2-hydroxyisobutyrylation(K_(hib))plays an important role in gene transcription,metabolism,and enzymatic activity.K_(hib)sites have been identified in rice(Oryza sativa).However,the K_(hib)status of proteins in rice flowers during pathogen infection remains unclear.Here,we report a comprehensive identification of K_(hib)-modified proteins in rice flowers,and the changes in these proteins during infection with the fungal pathogen Ustilaginoidea virens.By using a tandem mass tag-based quantitative proteomics approach,we identified 2,891 K_(hib)sites on 964 proteins in rice flowers.Our data demonstrated that 2-hydroxyisobutyrylated proteins are involved in diverse biological processes.K_(hib)levels were substantially reduced upon infection with U.virens.Chromatin immunoprecipitation polymerase chain reaction(PCR)and reverse transcription quantitative PCR analyses revealed that histone K_(hib)is involved in the expression of disease-resistance genes.More importantly,most quantified sites on core histones H3 were downregulated upon U.virens infection.In addition,the histone deacetylases HDA705,HDA716,SRT1,and SRT2 are involved in the removal of K_(hib)marks in rice.HDA705 was further confirmed to negatively regulate rice disease resistance to pathogens U.virens,Magnaporthe oryzae,and Xanthomonas oryzae pv.oryzae(Xoo).Our data suggest that U.virens could modulate K_(hib)in rice flowers during infection. | Xiaoyang Chen Qiutao Xu Yuhang Duan Hao Liu Xiaolin Chen Junbin Huang Chaoxi Luo Dao-Xiu Zhou Lu Zheng | 2021 | Journal of Integrative Plant Biology2021，63，10： | 1 |
| 11 | UvWhi2 Is Required for Stress Response and Pathogenicity in Ustilaginoidea virens显示文摘Some stress response-related genes have been identified in Ustilaginoidea virens,but it is not clear whether and how defects of stress responses affect the pathogenesis processes of U.virens.In this study,we identified a general stress response factor UvWHI2 as a homolog of Saccharomyces cerevisiae Whi2 in U.virens.The relative expression level of Uv Whi2 was significantly up-regulated during infection,suggesting that UvWHI2 may be involved in pathogenesis.Furthermore,knockout of Uv Whi2 showed decreased mycelial growth,increased conidiation in the potato sucrose medium and a defect in pathogenicity.In addition,the RNA-Seq and phenotypic analysis showed that UvWHI2 was involved in response to oxidative,hyperosmotic,cell wall stress and nutrient limitation.Further studies revealed that the defects of stress responses of the?Uvwhi2 mutant affected the formation of secondary spores on the nutrient limited surface and the rice surface,resulting in a significant reduction of pathogenicity of U.virens.Our results suggest that UvWHI2 is necessary for fungal growth,stress responses and the formation of secondary spores in U.virens.In addition,the defects of stress responses can affect the formation of secondary spores on the rice surface,and then compromise the pathogenicity of U.virens. | MENG Shuai QIU Jiehua XIONG Meng LIU Zhiquan Jane Sadhna JAGERNATH LIN Fucheng SHI Huanbin KOU Yanjun | 2022 | Rice science2022，29，1： | 0 |

| 16 | UvSMEK1,a Suppressor of MEK Null,Regulates Pathogenicity,Conidiation and Conidial Germination in Rice False Smut Fungus Ustilaginoidea virens显示文摘Rice false smut,which is caused by Ustilaginoidea virens,is an emerging disease of rice spikelets in rice-growing areas worldwide.However,the infection mechanism of U.virens on rice spikelets is still unclear.Here,we characterized a suppressor of mitogen-activated protein kinase kinase or ERK kinase(MEK)null(UvSMEKI)in U.virens that is conserved among filamentous fungi.Compared with wild type U.virens strain P-1,UvSMEKI deletion mutants were defective in pathogenicity and conidial germination.In addition,conidiation of UvSMEKI deletion mutants was significantly reduced on yeast extract tryptone(YT)plates,but inc「eased in YT broth compared with the wild type.Compared with UvSMEKI expression level during the vegetative mycelia and conidiation stages,UvSMEKI dramatically increased during infection of rice florets.Surprisingly,the UvSMEKI deletion mutants exhibited higher tolerance to H_(2)O_(2) and NaCl.In summary,presented evidence suggested that UvSMEKI positively regulated pathogenicity,conidial germination and conidiation in YT broth,and negatively regulated conidiation on YT medium and tolerance to oxidative and osmotic stresses.The results enhanee our understanding of the regulatory mechanism of pathogenicity of U.virens,and present a potential molecular target for blocking rice infection by U.virens. | Yu Junjie Yu Mina SONG Tianqiao CAO Huijuan Yong Mingli Pan Xiayan Qi Zhongqiang Du Yan Zhang Rongsheng Yin Xiaole Liang Dong Liu Yongfeng | 2021 | Rice science2021，28，5： | 0 |
