| 1 | A Chromosome-Level Genome Assembly of Garlic (Allium sativum) Provides Insights into Genome Evolution and Allicin Biosynthesis显示文摘Garlic,an economically important vegetable,spice,and medicinal crop,produces highly enlarged bulbs and unique organosulfur compounds.Here,we report a chromosome-level genome assembly for garlic,with a total size of approximately 16.24 Gb,as well as the annotation of 57561 predicted protein-coding genes,making garlic the first Allium species with a sequenced genome.Analysis of this garlic genome assembly reveals a recent burst of transposable elements,explaining the substantial expansion of the garlic genome.We examined the evolution of certain genes associated with the biosynthesis of allicin and inulin neoseries-type fructans,and provided new insights into the biosynthesis of these two compounds.Furthermore,a large-scale transcriptome was produced to characterize the expression patterns of garlic genes in different tissues and at various growth stages of enlarged bulbs.The reference genome and large-scale transcriptome data generated in this study provide valuable new resources for research on garlic biology and breeding. | Xiudong Sun Siyuan Zhu Ningyang Li Yi Cheng Jing Zhao Xuguang Qiao Li Lu Shiqi Liu Yanzhou Wang Chan Liu Benping Li Wu Guo Shuang Gao Zemao Yang Fu Li Zheng Zeng Qing Tang Yupeng Pan Mengjiao Guan Jian Zhao Xiaomi ng Lu Huanwe n Meng Zhenlin Han Chun she ng Gao Wenkai Jiang Xing Zhao Shilin Tian Jianguang Su Zhihui Cheng Touming Liu | 2020 | Molecular Plant2020，13，9： | 14 |
| 2 | Integrated photonic RF self-interference cancellation on a silicon platform for full-duplex communication显示文摘In-band full-duplex(IBFD) technology can double the spectrum utilization efficiency for wireless communications,and increase the data transmission rate of B5G and 6G networks and satellite communications. RF self-interference is the major challenge for the application of IBFD technology, which must be resolved. Compared with the conventional electronic method, the photonic self-interference cancellation(PSIC) technique has the advantages of wide bandwidth, high amplitude and time delay tuning precision, and immunity to electromagnetic interference.Integrating the PSIC system on chip can effectively reduce the size, weight, and power consumption and meet the application requirement, especially for mobile terminals and small satellite payloads. In this paper, the silicon integrated PSIC chip is presented first and demonstrated for IBFD communication. The integrated PSIC chip comprises function units including phase modulation, time delay and amplitude tuning, sideband filtering, and photodetection, which complete the matching conditions for RF self-interference cancellation. Over the wide frequency range of C, X, Ku, and K bands, from 5 GHz to 25 GHz, a cancellation depth of more than 20 dB is achieved with the narrowest bandwidth of 140 MHz. A maximum bandwidth of 630 MHz is obtained at a center frequency of10 GHz. The full-duplex communication experiment at Ku-band by using the PSIC chip is carried out. Cancellation depths of 24.9 dB and 26.6 dB are measured for a bandwidth of 100 MHz at central frequencies of 12.4 GHz and14.2 GHz, respectively, and the signal of interest(SOI) with 16-quadrature amplitude modulation is recovered successfully. The factors affecting the cancellation depth and maximum interference to the SOI ratio are investigated in detail. The performances of the integrated PSIC system including link gain, noise figure, receiving sensitivity, and spurious free dynamic range are characterized. | XIUYOU HAN XINXIN SU MENG CHAO XINDI YANG WEIHENG WANG SHUANGLING FU YICHENG DU ZHENLIN WU MINGSHAN ZHAO | 2023 | Photonics Research2023，11，10： | 1 |

| 5 | Characterization and Candidate Gene Analysis of the Yellow-Green Leaf Mutant ygl16 in Rice(Oryza sativa L.)显示文摘Leaf color mutants are ideal materials for studying many plant physiological and metabolic processes such as photosynthesis,photomorphogenesis,hormone physiology and disease resistance.In this study,the genetically stable yellow-green leaf mutant ygl16 was identified from mutated“Xinong 1B”.Compared with the wild type,the pigment concentration and photosynthetic capacity of the ygl16 decreased significantly.The ultrastructural observation showed that the distribution of thylakoid lamellae was irregular in ygl16 chloroplasts,and the grana and matrix lamellae were blurred and loose in varied degrees,and the chloroplast structure was disordered,while the osmiophilic corpuscles increased.The results of the genetic analysis and mapping showed that the phenotype of ygl16 was controlled by a pair of recessive nuclear gene.The gene located in the 56Kb interval between RM25654 and R3 on the long arm of chromosome 10.The sequencing results showed that the 121st base of the first intron of the candidate gene OsPORB/FGL changed from A to T in the interval.qRT-PCR results showed that the expression of chlorophyll synthase-related genes in the mutant decreased. | Linjun Cai Junhua Liu Han Yun Dan Du Xiaolong Zhong Zhenlin Yang Xianchun Sang Changwei Zhang | 2021 | Phyton-International Journal of Experimental Botany2021，90，4： | 1 |
| 6 | Quantitative analysis of collagen morphology in breast cancer from millimeter scale using multiphoton microscopy显示文摘The tumor microenvironment(TME)is now recognized as an important participant of tumor progression.As the most abundant extracellular matrix component in TME,collagen plays an important role in tumor development.The imaging study of collagen morphological feature in TME is of great significance for understanding the state of tumor.Multiphoton microscopy(MPM),based on second harmonic generation(SHG)and two-photon excitation fluorescence(TPEF),can be used to monitor the morphological changes of biological tissues without labeling.In this study,we used MPM for large-scale imaging of early invasive breast cancer from the tumor center to normal tissues far from the tumor.We found that there were signi¯cant di®erences in collagen morphology between breast cancer tumor boundary,near tumor transition region and normal tissues far from the tumor.Furthermore,the morphological feature of eight collagen¯bers was extracted to quantify the variation trend of collagen in three regions.These results may provide a new perspective for the optimal negative margin width of breast-conserving surgery and the understanding of tumor metastasis. | Yulan Liu Shunwu Xu Deyong Kang Xingxin Huang Shuoyu Xu Lianhuang Li Liqin Zheng Lida Qiu Zhenlin Zhan Xiahui Han Jianxin Chen | 2023 | Journal of Innovative Optical Health Sciences2023，16，4： | 0 |

| 8 | Plasmonic evolution of atomically size-selected Au clusters by electron energy loss spectrum显示文摘The plasmonic response of gold clusters with atom number(N)=100–70000 was investigated using scanning transmission electron microscopy-electron energy loss spectroscopy.For decreasing N,the bulk plasmon remains unchanged above N=887 but then disappears,while the surface plasmon firstly redshifts from 2.4 to 2.3 e V above N=887 before blueshifting towards 2.6 e V down to N=300,and finally splitting into three fine features.The surface plasmon’s excitation ratio is found to follow N^(0.669),which is essentially R^(2).An atomically precise evolution picture of plasmon physics is thus demonstrated according to three regimes:classical plasmon(N=887–70000),quantum confinement corrected plasmon(N=300–887)and molecule related plasmon(N<300). | Siqi Lu Lin Xie Kang Lai Runkun Chen Lu Cao Kuojuei Hu Xuefeng Wang Jinsen Han Xiangang Wan Jianguo Wan Qing Dai Fengqi Song Jiaqing He Jiayu Dai Jianing Chen Zhenlin Wang Guanghou Wang | 2021 | National Science Review2021，8，12： | 0 |
