| 1 | Rice metabolic regulatory network spanning the entire life cycle显示文摘As one of the most important crops in the world,rice(Oryza sativa)is a model plant for metabolome research.Although many studies have focused on the analysis of specific tissues,the changes in metab-olite abundance across the entire life cycle have not yet been determined.In this study,combining both tar-geted and nontargeted metabolite profiling methods,a total of 825 annotated metabolites were quantified in rice samples from different tissues covering the entire life cycle.The contents of metabolites in different tissues of rice were significantly different,with various metabolites accumulating in the plumule and radicle during seed germination.Combining these data with transcriptome data obtained from the same time period,we constructed the Rice Metabolic Regulation Network.The metabolites and co-expressed genes were further divided into 12 clusters according to their accumulation patterns,with members within each cluster displaying a uniform and clear pattern of abundance across development.Using this dataset,we established a comprehensive metabolic profile of the rice life cycle and used two independent strategies to identify novel transcription factors-namely the use of known regulatory genes as bait to screen for new networks underlying lignin metabolism and the unbiased identification of new glycerophospholipid metabolism regulators on the basis of tissue specificity.This study thus demonstrates how guilt-by-association analysis of metabolome and transcriptome data spanning the entire life cycle in cereal crops provides novel resources and tools to aid in understanding the mechanisms underlying important agro-nomic traits. | Chenkun Yang Shuangqian Shen Shen Zhou Yufei Li Yuyuan Mao Junjie Zhou Yuheng Shi Longxu An Qianqian Zhou Wenju Peng Yuanyuan Lyu Xuemei Liu Wei Chen Shouchuang Wang Lianghuan Qu Xianqing Liu Alisdair R.Fernie Jie Luo | 2022 | Molecular Plant2022，15，2： | 3 |
| 2 | Branched-chain amino acids regulate plant growth by affecting the homeostasis of mineral elements in rice显示文摘Dear Editor,Branched-chain amino acids(BCAAs)are essential amino acids that must be obtained from the diet for humans and animals.Branched-chain amino acid transaminases(BCATs)catalyze a key step in the BCAA synthesis pathway,however,little is known about their biological roles in planta.In this study,we functionally characterized two BCATs,OsBCAT4 and OsBCAT5,in rice and showed that they regulate the development of rice roots by affecting the levels of mineral elements. | Cheng Jin Yangyang Sun Yuheng Shi Yuanyuan Zhang Kai Chen Yuan Li Guige Liu Fang Yao Deng Cheng Jie Li Junjie Zhou Lianghuan Qu Xianqing Liu Jie Luo | 2019 | Science China(Life Sciences)2019，62，8： | 3 |

| 4 | GaN based ultraviolet laser diodes显示文摘In the past few years,many groups have focused on the research and development of GaN-based ultraviolet laser diodes(UV LDs).Great progresses have been achieved even though many challenges exist.In this article,we analyze the challenges of developing GaN-based ultraviolet laser diodes,and the approaches to improve the performance of ultraviolet laser diode are reviewed.With these techniques,room temperature(RT)pulsed oscillation of AlGaN UVA(ultraviolet A)LD has been realized,with a lasing wavelength of 357.9 nm.Combining with the suppression of thermal effect,the high output power of 3.8 W UV LD with a lasing wavelength of 386.5 nm was also fabricated. | Jing Yang Degang Zhao Zongshun Liu Yujie Huang Baibin Wang Xiaowei Wang Yuheng Zhang Zhenzhuo Zhang Feng Liang Lihong Duan Hai Wang Yongsheng Shi | 2024 | Journal of Semiconductors2024，45，1： | 0 |
| 5 | 3D‑Printed Carbon‑Based Conformal Electromagnetic Interference Shielding Module for Integrated Electronics显示文摘Electromagnetic interference shielding(EMI SE)modules are the core com-ponent of modern electronics.However,the tra-ditional metal-based SE modules always take up indispensable three-dimensional space inside electronics,posing a major obstacle to the integra-tion of electronics.The innovation of integrating 3D-printed conformal shielding(c-SE)modules with packaging materials onto core electronics offers infinite possibilities to satisfy ideal SE func-tion without occupying additional space.Herein,the 3D printable carbon-based inks with various proportions of graphene and carbon nanotube nanoparticles are well-formulated by manipulating their rheological peculiarity.Accordingly,the free-constructed architectures with arbitrarily-customized structure and multifunctionality are created via 3D printing.In particular,the SE performance of 3D-printed frame is up to 61.4 dB,simultaneously accompanied with an ultralight architecture of 0.076 g cm^(-3) and a superhigh specific shielding of 802.4 dB cm3 g^(-1).Moreover,as a proof-of-concept,the 3D-printed c-SE module is in situ integrated into core electronics,successfully replacing the traditional metal-based module to afford multiple functions for electromagnetic compatibility and thermal dissipa-tion.Thus,this scientific innovation completely makes up the blank for assembling carbon-based c-SE modules and sheds a brilliant light on developing the next generation of high-performance shielding materials with arbitrarily-customized structure for integrated electronics. | Shaohong Shi Yuheng Jiang Hao Ren Siwen Deng Jianping Sun Fangchao Cheng Jingjing Jing Yinghong Chen | 2024 | Nano-Micro Letters2024，16，5： | 0 |
| 6 | Natural variations of OsAUX5,a target gene of OsWRKY78,control the neutral essential amino acid content in rice grains显示文摘Grain essential amino acid(EAA)levels contribute to rice nutritional quality.However,the molecular mechanisms underlying EAA accumulation and natural variation in rice grains remain unclear.Here we report the identification of a previously unrecognized auxin influx carrier subfamily gene,OsAUX5,which encodes an amino acid transporter that functions in uptake of multiple amino acids.We identified an elite haplotype of Pro::OsAUX5^(Hap2) that enhances grain EAA accumulation without an apparent negative effect on agronomic traits.Natural variations of OsAUX5 occur in the cis elements of its promoter,which are differentially activated because of the different binding affinity between OsWRKY78 and the W-box,contributing to grain EAA variation among rice varieties.The two distinct haplotypes were shown to have originated from different Oryza rufipogon progenitors,which contributed to the divergence between japonica and indica.Introduction of the indica-type Pro::OsAUX5^(Hap2) genotype into japonica could significantly increase EAA levels,indicating that indica-type Pro::OsAUX5^(Hap2) can be utilized to increase grain EAAs of japonica varieties.Collectively,our study uncovers an WRKY78–OsAUX5-based regulatory mechanism controlling grain EAA accumulation and provides a potential target for breeding EAA-rich rice. | Yuheng Shi Yuanyuan Zhang Yangyang Sun Ziyang Xie Yu Luo Qiyuan Long Jiahui Feng Xueqing Liu Bi Wang Dujun He Junxia Ren Peizhen Guo Junwei Xing Liqiang He Alisdair RFernie Wei Chen Xianqing Liu Yuehua Luo Cheng Jin Jie Luo | 2023 | Molecular Plant2023，16，2： | 0 |
| 7 | Integration of rhythmic metabolome and transcriptome provides insights into the transmission of rhythmic fluctuations and temporal diversity of metabolism in rice显示文摘Various aspects of the organisms adapt to cyclically changing environmental conditions via transcriptional regulation.However,the role of rhythmicity in altering the global aspects of metabolism is poorly characterized.Here,we subjected four rice(Oryza sativa)varieties to a range of metabolic profiles and RNA-seq to investigate the temporal relationships of rhythm between transcription and metabolism.More than 40%of the rhythmic genes and a quarter of metabolites conservatively oscillated across four rice accessions.Compared with the metabolome,the transcriptome was more strongly regulated by rhythm;however,the rhythm of metabolites had an obvious opposite trend between day and night.Through association analysis,the time delay of rhythmic transmission from the transcript to the metabolite level was~4 h under long-day conditions,although the transmission was nearly synchronous for carbohydrate and nucleotide metabolism.The rhythmic accumulation of metabolites maintained highly coordinated temporal relationships in the metabolic network,whereas the correlation of some rhythmic metabolites,such as branched-chain amino acids(BCAAs),was significantly different intervariety.We further demonstrated that the cumulative diversity of BCAAs was due to the differential expression of branched-chain aminotransferase 2 at dawn.Our research reveals the flexible pattern of rice metabolic rhythm existing with conservation and diversity. | Junjie Zhou Chengyuan Liu Qiyu Chen Ling Liu Shuying Niu Ridong Chen Kang Li Yangyang Sun Yuheng Shi Chenkun Yang Shuangqian Shen Yufei Li Junwei Xing Honglun Yuan Xianqing Liu Chuanying Fang Alisdair R.Fernie Jie Luo | 2022 | Science China(Life Sciences)2022，65，9： | 0 |
