| 1 | Phytophthora Effectors Modulate Genome-wide Alternative Splicing of Host mRNAs to Reprogram Plant Immunity显示文摘Alternative splicing(AS)of pre-mRNAs increases transcriptome and proteome diversity,regulates gene expression through multiple mechanisms,and plays important roles in plant development and stress responses.However,the prevalence of genome-wide plant AS changes during infection and the mechanisms by which pathogens modulate AS remain poorly understood.Here,we examined the global AS changes in tomato leaves infected with Phytophthora infestans,the infamous Irish famine pathogen.We show that more than 2000 genes exhibiting significant changes in AS are not differentially expressed,indicating that AS is a distinct layer of transcriptome reprogramming during plant-pathogen interactions.Furthermore,our results show that P.infestans subverts host immunity by repressing the AS of positive regulators of plant immunity and promoting the AS of susceptibility factors.To study the underlying mechanism,we established a luminescence-based AS reporter system in Nicotiana benthamiana to screen pathogen effectors modulating plant AS.We identified nine splicing regulatory effectors(SREs)from 87 P.infestans effectors.Further studies revealed that SRE3 physically binds U1-70K to manipulate the plant AS machinery and subsequently modulates AS-mediated plant immunity.Our study not only unveils genome-wide plant AS reprogramming during infection but also establishes a novel AS screening tool to identify SREs from a wide range of plant pathogens,providing opportunities to understand the splicing regulatory mechanisms through which pathogens subvert plant immunity. | Jie Huang Xinyu Lu Hongwei Wu Yuchen Xie Qian Peng Lianfeng Gu Juyou Wu Yuanchao Wang Anireddy SNReddy Suomeng Dong | 2020 | Molecular Plant2020，13，10： | 4 |
| 2 | Novel degradation products of argatroban: Isolation, synthesis and extensive characterization using NMR and LC-PDA-MS/Q-TOF显示文摘Forced degradation study of argatroban under conditions of hydrolysis(neutral, acidic and alkaline), oxidation,photolysis and thermal stress, as suggested in the ICH Q1 A(R2), was accomplished. The drug showed significant degradation under hydrolysis(acidic, alkaline) and oxidation(peroxide stress) conditions. The drug remained stable under thermal and photolytic stress conditions. In total, seven novel degradation products(DP-1 to DP-7) were found under diverse conditions, which were not reported earlier. The chemical structures of these degradation products were characterized by ~1H NMR,^(13)C NMR, 2 D NMR, Q-TOF-MSnand IR spectral analysis and the proposed degradation products structures were further confirmed by the individual synthesis. | Vinodh Guvvala Venkatesan Chidambaram Subramanian Jaya Shree Anireddy Mahesh Konda | 2018 | Journal of Pharmaceutical Analysis2018，8，2： | 4 |
| 3 | Profiling of circular RNA N^(6)-methyladenosine in moso bamboo(Phyllostachys edulis)using nanopore-based direct RNA sequencing显示文摘N6-methyladenosine(m^(6)A)is a prevalent modification in messenger RNAs and circular RNAs that play important roles in regulating various aspects of RNA metabolism.However,the occurrence of the m^(6)A modification in plant circular RNAs has not been reported.A widely used method to identify m^(6)A modifications relies on m^(6)A-specific antibodies followed by next-generation sequencing of precipitated RNAs(MeRIP-Seq).However,one limitation of MeRIP-Seq is that it does not provide the precise location of m^(6)A at single-nucleotide resolution.Although more recent sequencing techniques such as Nanopore-based direct RNA sequencing(DRS)can overcome such limitations,the technology does not allow sequencing of circular RNAs,as these molecules lack a poly(A)tail.Here,we developed a novel method to detect the precise location of m^(6)A modifications in circular RNAs using Nanopore DRS.We first enriched our samples for circular RNAs,which we then fragmented and sequenced on the Nanopore platform with a customized protocol.Using this method,we identified 470 unique circular RNAs from DRS reads based on the back-spliced junction region.Among exonic circular RNAs,about 10%contained m^(6)A sites,which mainly occurred around acceptor and donor splice sites.This study demonstrates the utility of our antibody-independent method in identifying total and methylated circular RNAs using Nanopore DRS.This method has the additional advantage of providing the exact location of m^(6)A sites at single-base resolution in circular RNAs or linear transcripts from non-coding RNA without poly(A)tails. | Yongsheng Wang Huihui Wang Feihu Xi Huiyuan Wang Ximei Han Wentao Wei Hangxiao Zhang Qianyue Zhang Yushan Zheng Qiang Zhu Markus V.Kohnen Anireddy S.N.Reddy Lianfeng Gu | 2020 | Journal of Integrative Plant Biology2020，62，12： | 3 |

| 6 | Genome-wide profiling of circular RNAs,alternative splicing,and R-loops in stem-differentiating xylem of Populus trichocarpa显示文摘Circular RNAs(circRNAs)are a recently dis-covered type of non‐coding RNA derived from pre‐mRNAs.R‐loops consist of a DNA:RNA hybrid andthe associated single‐stranded DNA.InArabi-dopsis thaliana,circRNA:DNA R‐loops regulatealternative splicing(AS)ofSEPALLATA3(SEP3).However,the occurrence and functions ofcircRNAs and R‐loops inPopulus trichocarpaarelargely unexplored.Here,we performed circRNA‐enriched sequencing in the stem‐differentiatingxylem(SDX)ofP.trichocarpaand identified 2,742distinct circRNAs,including circ‐CESA4,circ‐IRX7,and circ‐GUX1,which are generated from genesinvolved in cellulose,and hemicellulose biosyn-thesis,respectively.To investigate the roles ofcircRNAs in modulating alternative splicing(AS),we detected 7,836 AS events using PacBio Iso‐Seq and identified 634 circRNAs that overlappedwith 699 AS events.Furthermore,using DNA:RNAhybrid immunoprecipitation followed by se-quencing(DRIP‐seq),we identified 8,932 R‐looppeaks that overlapped with 181 circRNAs and 672AS events.Notably,several SDX‐related circRNAsoverlapped with R‐loop peaks,pointing to theirpossible roles in modulating AS in SDX.Indeed,overexpressing circ‐IRX7increased the levels ofR‐loop structures and decreased the frequency ofintron retention in linearIRX7transcripts.Thisstudy provides a valuable R‐loop atlas resourceand uncovers the interplay between circRNAs andAS in SDX ofP.trichocarpa. | Xuqing Liu Yubang Gao Jiakai Liao Miao Miao Kai Chen Feihu Xi Wentao Wei Huihui Wang Yongsheng Wang XiXu Anireddy S.N.Reddy Lianfeng Gu | 2021 | Journal of Integrative Plant Biology2021，63，7： | 1 |
