| 1 | A reactive oxygen species burst causes haploid induction in maize显示文摘Haploid induction (HI) is an important tool in crop breeding. Phospholipase A1 (ZmPLA1)/NOT LIKE DAD (NLD)/MATRILINEAL (MTL) is a key gene controlling HI in maize;however, the underlying molecular mechanism remains unclear. In this study, to dissect why loss of ZmPLA1 function could mediate HI we performed a comprehensive multiple omics analysis of zmpla1 mutant anthers by integrating transcriptome, metabolome, quantitative proteome, and protein modification data. Functional classes of significantly enriched or differentially abundant molecular entities were found to be associated with the oxidative stress response, suggesting that a reactive oxygen species (ROS) burst plays a critical role in HI. In support of this, we further discovered that a simple chemical treatment of pollen with ROS reagents could lead to HI. Moreover, we identified ZmPOD65, which encodes a sperm-specific peroxidase, as a new gene controlling HI. Taken together, our study revealed a likely mechanism of HI, discovered a new gene controlling HI, and created a new method for HI in maize, indicating the importance of ROS balance in maintaining normal reproduction and providing a potential route to accelerate crop breeding. | Chenglin Jiang Ju Sun Rui Li Shijuan Yan Wei Chen Liang Guo Guochen Qin Pengcheng Wang Cheng Luo Wenjie Huang Qinghua Zhang Alisdair R.Fernie David Jackson Xiang Li Jianbing Yan | 2022 | Molecular Plant2022，15，6： | 2 |
| 2 | Dynamics and genetic regulation of macronutrient concentrations during grain development in maize显示文摘Nitrogen(N), phosphorus(P), and potassium(K) are essential macronutrients that are crucial not only for maize growth and development, but also for crop yield and quality. The genetic basis of macronutrient dynamics and accumulation during grain filling in maize remains largely unknown. In this study, we evaluated grain N, P, and K concentrations in 206 recombinant inbred lines generated from a cross of DH1M and T877 at six time points after pollination. We then calculated conditional phenotypic values at different time intervals to explore the dynamic characteristics of the N, P, and K concentrations. Abundant phenotypic variations were observed in the concentrations and net changes of these nutrients. Unconditional quantitative trait locus(QTL) mapping revealed 41 non-redundant QTLs, including 17, 16, and 14 for the N, P, and K concentrations, respectively. Conditional QTL mapping uncovered 39 non-redundant QTLs related to net changes in the N, P, and K concentrations. By combining QTL, gene expression, co-expression analysis, and comparative genomic data, we identified 44, 36, and 44 candidate genes for the N, P, and K concentrations, respectively, including GRMZM2G371058 encoding a Doftype zinc finger DNA-binding family protein, which was associated with the N concentration, and GRMZM2G113967encoding a CBL-interacting protein kinase, which was related to the K concentration. The results deepen our understanding of the genetic factors controlling N, P, and K accumulation during maize grain development and provide valuable genes for the genetic improvement of nutrient concentrations in maize. | Pengcheng Li Shuangyi Yin Yunyun Wang Tianze Zhu Xinjie Zhu Minggang Ji Wenye Rui Houmiao Wang Chenwu Xu Zefeng Yang | 2024 | Journal of Integrative Agriculture2024，23，3： | 0 |
| 3 | Analyzing electrostatic modulation of signal transduction efficiency in MoS_(2) nanoelectromechanical resonators with interferometric readout显示文摘Optical interferometry is a highly sensitive method for detecting the miniscule resonant motion in two-dimensional(2D)nanoelectromechanical systems(NEMS).However,the technique to control the interferometry signal strength has not been fully understood.In this work,we present analytical modeling of an effective method for tuning motion-to-signal responsivity in interferometric detection of 2D molybdenum disulfide(MoS_(2))NEMS resonators.We show that the responsivity can be tuned very efficiently,all the way from maximum to 0,by varying the vacuum gap underneath the 2D membrane electrostatically.We further show that the gate voltage corresponding to 0 responsivity,which means no motion signal can be detected,varies with the MoS_(2)thickness,diameter,pre-strain,and initial vacuum gap.Our findings provide an important guideline for optimizing measurement conditions when detecting motion in 2D NEMS structures using laser interferometry. | Jiankai ZHU Pengcheng ZHANG Rui YANG Zenghui WANG | 2022 | Science China(Information Sciences)2022，65，2： | 0 |

| 6 | Nanomechanics:emerging opportunities for future computing显示文摘The exploration for greater computing power has existed for a long time.Since the 1960 s,transistors in modern electronic computers have kept advancing following Moore's law.However,as silicon transistors continue to scale down,they face challenges such as increases in OFF-state leakage power due to the limited subthreshold swing,incompatibility with high-temperature operation,and lack of reconfigurability.Therefore,new types of computing devices are being explored to address these problems. | Zenghui WANG Jiawei FANG Pengcheng ZHANG Rui YANG | 2021 | Science China(Information Sciences)2021，64，10： | 0 |
| 7 | State-of-Health Map of Lithium-ion Batteries Established by ICE Map Approach显示文摘State-of-health(SOH) is one of the main factors for lithium-ion batteries that indicate their life information. Thus it is essential to estimate SOH accurately during the operation of lithium-ion batteries. In this paper, an SOH map is proposed to illustrate the SOH of lithium-ion batteries by an internal combustion engine(ICE) map approach. Both direct current internal resistance(DCR) and open circuit voltage(OCV) are key parameters of lithium-ion batteries, which are obtained through metering and computing. Due to serious affection by environmental temperature, temperature translation is proposed to translate DCR/OCV of different temperature into a nominal value at 25 ℃. Compared with ICE map, SOH map is illustrated by the nominal DCR and OCV, which can be looked up to get a nominal SOH. In the SOH map, a pair of the DCR and the OCV can only map out a unique SOH, which is beneficial for application in engineering practice in most cases. | Lin He Mingwei Wang Yujiang Wei Pengcheng Rui Shengjie Yu Qin Shi | 2022 | Journal of Harbin Institute of Technology(New Series)2022，29，3： | 0 |
| 8 | Particle-Wave Dualism in Nanoconfined Space:Ultrafast Substance Flow显示文摘Many researchers,however,found that(1)the flow of both liquid and gas through nanoscale pores is one to even seven orders of magnitude faster than that would be predicted from the classic Newton’s mechanic theories,such as the Hagen-Poiseuille equation,the Bernoulli’s principle,the Knudsen theory;(2)the seeming contradiction that K+channels conduct K+ions at maximal throughput rates while not permeating slightly smaller Na+ions,which have perplexed scientists for decades.Herein we propose a possible explanation for the above phenomena based on the Wave-Particle Dualism.The quantum effect on ultrafast flow could possibly provide a new perspective for studying the nature of the ion and molecule channels,which are the backbones for the biology,and possibly promote the development of new methods for energy conversion,desalination of sea water and even information systems. | GAO Pengcheng MA Qun LIU Rui LOU Xiaoding HUANG Yu ZHANG Baocheng XIA Fan | 2022 | Chemical Research in Chinese Universities2022，38，4： | 0 |
