| 1 | Brassinosteroid and gibberellin coordinate rice seed germination and embryo growth by regulating glutelin mobilization显示文摘Seed germination is the beginning of a new lifecycle,and involves many complex physiological and biochemical reactions including seed reserve mobilization in the endosperm and nutrient transport and reuse in the embryo.Although glutelin is a dominant storage protein in rice,its contribution to seed germination and its regulatory mechanisms are mostly unknown.Gibberellin (GA) and brassinosteroid (BR),two major growth-promoting phytohormones,also play positive roles in controlling seed germination.However,how GA and BR interact and coordinate seed germination and facilitate glutelin mobilization remains unclear.In the present study,biochemical and physiological analyses of seed germination indicated that both GA and BR promote seed germination and post-germination growth.Exogenous application of GA restored germination defects caused by BR deficiency or insensitivity.Proteomic and q RT-PCR results showed that the expression of several glutelin proteins and their encoding genes was induced by BR and GA in the embryo.Expression assays suggested that the increased accumulation of glutelin protein in the embryo was due to the accelerated degradation of glutelin by a cysteine proteinase (REP-1) in the endosperm.The breakdown of glutelin in the endosperm showed a strict positive correspondence with the length of the shoot.The GluA2 mutation led to reduced degradation rate of glutelin and defects in seed germination,and the promotion effect of GA on seed germination was weakened in the glua2mutant.In vitro culture assay of rice embryos showed that glutelin mobilization functioned downstream of the GA and BR pathways to promote shoot elongation.These findings suggest a mechanism that mediates crosstalk between BR and GA in co-regulating rice seed germination and embryo growth. | Min Xiong Lingyi Chu Qianfeng Li Jiawen Yu Yihao Yang Peng Zhou Yong Zhou Changquan Zhang Xiaolei Fan Dongsheng Zhao Changjie Yan Qiaoquan Liu | 2021 | The Crop Journal2021，9，5： | 1 |
| 2 | Optimization of synergistic energy storage density and efficiency for eco-friendly (Na_(0.5)Bi_(0.5))_(0.6)Sr_(0.4)TiO_(3)-based relaxor ferroelectric ceramics显示文摘Inspired by increasing demand of advanced pulsed power capacitors,the development of lead-free dielectric ceramic capacitors with high energy storage density and temperature-insensitive performance are extremely crucial.Herein,the lead-free relaxor ferroelectric ceramics based on(1-x)(Na_(0.5)Bi_(0.5))0.6Sr_(0.4)TiO_(3-x)Sr_(0.7)La_(0.2)ZrO_(3)[abbreviated as(1-x)NBST-xSLZ]are prepared by the solid-state reaction route.The large recoverable energy density(Wrec)of 3.45 J/cm^(3) and efficiency(h)of 90.1%are simultaneously realized in 0.86NBST-0.14SLZ ceramic due to increased breakdown strength.Furthermore,both the Wrec and h of 0.86NBST-0.14SLZ ceramic display superior of thermal stability(20e180C),frequency stability(1e1000 Hz),and cycle stability(10^(4))within a satisfactory range of variation.In addition,the 0.86NBST-0.14SLZ ceramic can also achieve a large current density(CD)of 625 A/cm^(2),an ultrahigh power density(PD)of 50 MW/cm^(3) and a fast discharge rate(t0.90)of 160.8 ns at 160 kV/cm.These results demonstrate that the 0.86NBST-0.14SLZ ceramic could be a highly competitive and ecofriendly relaxor ferroelectric material for next-generation pulsed power capacitors. | Hu Di Pan Zhongbin Wu Lukang Yang Fan Tang Luomeng Zhao Jinghao Shen Yihao Chen Yuyun Li Peng Zhai Jiwei Liu Jinjun | 2021 | Journal of Materiomics2021，7，4： | 0 |
| 3 | Skill improvement of the yearly updated reforecasts in ECMWF S2S prediction from 2016 to 2022显示文摘在2016年至2022年间,ECMWF次季节预测系统不断升级并逐年完成新的回报试验。本文考察该预测系统逐年升级带来的预测技巧提升潜力.从2米气温和降水来看,在起报之后的前两周内天气尺度上预测技巧表现出逐年稳定提升的趋势;在从第三周开始的次季节时间尺度上,预测技巧的提升仅限于热带部分区域.MJO预测技巧并不随着模式升级而逐年单调提升.尽管目前S2S预测技巧存在局限性,但目前已有的进展增强了在未来深入合作以提高S2S预测技术的信心. | Yihao Peng Xiaolei Liu Jingzhi Su Xinli Liu Yixu Zhang | 2023 | Atmospheric and Oceanic Science Letters2023，16，5： | 0 |
