| 1 | FKF1 F-box protein promotes flowering in part by negatively regulating DELLA protein stability under long-day photoperiod in Arabidopsis^FA显示文摘FLAVIN-BINDING KELCH REPEAT F-BOX 1(FKF1)encodes an F-box protein that regulates photoperiod flowering in Arabidopsis under long-day conditions(LDs).Gibberellin(GA)is also important for regulating flowering under LDs.However,how FKF1 and the GA pathway work in concert in regulating flowering is not fully understood.Here,we showed that the mutation of FKF1 could cause accumulation of DELLA proteins,which are crucial repressors in GA signaling pathway,thereby reducing plant sensitivity to GA in flowering.Both in vitro and in vivo biochemical analyses demonstrated that FKF1 directly interacted with DELLA proteins.Furthermore,we showed that FKF1 promoted ubiquitination and degradation of DELLA proteins.Analysis of genetic data revealed that FKF1 acted partially through DELLAs to regulate flowering under LDs.In addition,DELLAs exerted a negative feedback on FKF1 expression.Collectively,these findings demonstrate that FKF1 promotes flowering partially by negatively regulating DELLA protein stability under LDs,and suggesting a potential mechanism linking the FKF1 to the GA signaling DELLA proteins. | Jindong Yan Xinmei Li Bingjie Zeng Ming Zhong Jiaxin Yang Piao Yang Xin Li Chongsheng He Jianzhong Lin Xuanming Liu Xiaoying Zhao | 2020 | Journal of Integrative Plant Biology2020，62，11： | 8 |
| 2 | Transcriptome-wide profiling of RNA N^(4)-cytidine acetylation in Arabidopsis thaliana and Oryza sativa显示文摘Acetylation of N^(4)-cytidine(ac^(4)C)has recently been discovered as a novel modification of mRNA.RNA ac^(4)C modification has been shown to be a key regulator of RNA stability,RNA translation,and the thermal stress response.However,its existence in eukaryotic mRNAs is still controversial.In plants,the existence,distribution pattern,and potential function of RNA ac^(4)C modification are largely unknown.Here we report the presence of ac^(4)C in the mRNAs of both Arabidopsis thaliana and rice(Oryza sativa).By comparing two ac^(4)C sequencing methods,we found that RNA immunoprecipitation and sequencing(acRIP-seq),but not ac^(4)C sequencing,was suitable for plant RNA ac^(4)C sequencing.We present transcriptome-wide atlases of RNA ac^(4)C modification in A.thaliana and rice mRNAs obtained by acRIP-seq.Analysis of the distribution of RNA ac^(4)C modifications showed that ac^(4)C is enriched near translation start sites in rice mRNAs and near translation start sites and translation end sites in Arabidopsis mRNAs.The RNA ac^(4)C modification level is positively correlated with RNA half-life and the number of splicing variants.Similar to that in mammals,the translation efficiency of ac^(4)C target genes is significantly higher than that of other genes.Our in vitro translation results confirmed that RNA ac^(4)C modification enhances translation efficiency.We also found that RNA ac^(4)C modification is negatively correlated with RNA structure.These results suggest that ac^(4)C is a conserved mRNA modification in plants that contributes to RNA stability,splicing,translation,and secondary structure formation. | Bin Li Donghao Li Linjun Cai Qiting Zhou Cong Liu Jianzhong Lin Yixing Li Xiaoying Zhao Li Li Xuanming Liu Chongsheng He | 2023 | Molecular Plant2023，16，6： | 0 |
| 3 | Power allocation for collaborative transmission in LTE-Advanced显示文摘Collaborative transmission among evolved Node-Bs(eNBs)is one of the promising techniques for LTE-Advanced to provide broader coverage and higher spectral efficiency.The interference among multi-cell transmission can be mitigated by joint precoding,such as multi-cell block diagonalization(BD)at cooperative eNBs.The major difference between multi-cell and single-cell transmission is that the power constraint has to be considered on a per-eNB basis.To satisfy per-eNB power constraint(PePC),a simplified power allocation algorithm for the multi-cell BD based collaborative transmission is proposed in this paper.The algorithm provides a power allocation coefficient matrix for BD to meet PePC.Simulation results demonstrate that the proposed algorithm has a near-optimal performance with simplicity. | Jing JIN Chongsheng LIN Qixing WANG Hongwen YANG Yafeng WANG | 2011 | Frontiers of Electrical and Electronic Engineering in China2011，6，4： | 0 |
