1Pepper variome reveals the history and key loci associated with fruit domestication and diversification显示文摘Pepper(Capsicum spp.)is an important vegetable crop that provides a unique pungent sensation when eaten.Through construction of a pepper variome map,we examined the main groups that emerged during domestication and breeding of C.annuum,their relationships and temporal succession,and the molecular events underlying the main transitions.The results showed that the initial differentiation in fruit shape and pungency,increase in fruit weight,and transition from erect to pendent fruits,as well as the recent appearance of large,blocky,sweet fruits(bell peppers),were accompanied by strong selection/fixation of key alleles and introgressions in two large genomic regions.Furthermore,we identified Up,which encodes a BIG GRAIN protein involved in auxin transport,as a key domestication gene that controls erect vs pendent fruit orientation.The up mutation gained increased expression especially in the fruit pedicel through a 579-bp sequence deletion in its 5′upstream region,resulting in the phenotype of pendent fruit.The function of Up was confirmed by virus-induced gene silencing.Taken together,these findings constitute a cornerstone for understanding the domestication and differentiation of a key horticultural crop.Yacong Cao Kang Zhang Hailong Yu Shumin Chen Donghui Xu Hong Zhao Zhenghai Zhang Yinqing Yang Xiaozhen Gu Xinyan Liu Haiping Wang Yaxin Jing Yajie Mei Xiang Wang Véronique Lefebvre Weili Zhang Yuan Jin Dongliang An Risheng Wang Paul Bosland Xixiang Li IIan Paran Baoxi Zhang Giovanni Giuliano Lihao Wang Feng Cheng 2022Molecular Plant2022,15,11:0
2Design of a micrometer-long superconducting nanowire perfect absorber for efficient high-speed single-photon detection显示文摘Despite very efficient superconducting nanowire single-photon detectors(SNSPDs)reported recently,combining their other performance advantages such as high speed and ultralow timing jitter in a single device still remains challenging.In this work,we present a perfect absorber model and the corresponding detector design based on a micrometer-long NbN nanowire integrated with a 2D photonic crystal cavity of ultrasmall mode volume,which promises simultaneous achievement of near-unity absorption,gigahertz counting rates,and broadband optical response with a 3 dB bandwidth of 71 nm.Compared to previous stand-alone meandered and waveguideintegrated SNSPDs,this perfect absorber design addresses the trade space in size,efficiency,speed,and bandwidth for realizing large on-chip single-photon detector arrays.RISHENG CHENG SIHAO WANG CHANG-LING ZOU HONG X.TANG 2020Photonics Research2020,8,8:0
3Parametric down-conversion photon-pair source on a nanophotonic chip显示文摘Quantum-photonic chips,which integrate quantum light sources alongside active and passive optical elements,as well as singlephoton detectors,show great potential for photonic quantum information processing and quantum technology.Mature semiconductor nanofabrication processes allow for scaling such photonic integrated circuits to on-chip networks of increasing complexity.Second-order nonlinear materials are the method of choice for generating photonic quantum states in the overwhelming majority of linear optic experiments using bulk components,but integration with waveguide circuitry on a nanophotonic chip proved to be challenging.Here,we demonstrate such an on-chip parametric down-conversion source of photon pairs based on second-order nonlinearity in an aluminum-nitride microring resonator.We show the potential of our source for quantum information processing by measuring the high visibility anti-bunching of heralded single photons with nearly ideal state purity.Our down-conversion source yields measured coincidence rates of 80 Hz,which implies MHz generation rates of correlated photon pairs.Low noise performance is demonstrated by measuring high coincidence-to-accidental ratios.The generated photon pairs are spectrally far separated from the pump field,providing great potential for realizing sufficient on-chip filtering and monolithic integration of quantum light sources,waveguide circuits and single-photon detectors.Xiang Guo Chang-ling Zou Carsten Schuck Hojoong Jung Risheng Cheng Hong X Tang 2016Light(Science & Applications)2016,5,1:0
4Boron Isotope Fractionation During Prolonged Ion Bombardment显示文摘Dynamic Monte Carlo simulation is used to explore the B isotope sputtering during 1 keV Kr ion irradiation.It is found that at both zero and high fluences the light isotope is preferentially ejected in the near-normal direction;meanwhile,there is a low fluence(1.4×10^(15) ions/cm^(2)),at which the isotope fractionation is independent of the emission angle in the nearly whole angular range.ZHENG Liping LI Risheng LI Mingyao CHENG Yulin 1991Chinese Physics Letters1991,8,6:0
5miR-338-3p acts as a tumor suppressor in lung squamous cell carcinoma by targeting FGFR2/FRS2显示文摘Background:Lung cancer refers to the occurrence of malignant tumors in the lung,and squamous cell carcinoma is one of the most common pathological types of non-small cell lung cancer.Studies have shown that microRNAs(miRNAs)play an important role in the occurrence,development,early diagnosis,and treatment of lung cancer.This study aimed to explore the role and possible mechanism of MicroRNA-338-3p(miR-338-3p)in lung squamous cell carcinoma(LUSC).Xia Shan Cheng Zhang Chunyu Li Xingchen Fan Guoxin Song Jingfeng Zhu Risheng Cao Xiuwei Zhang Wei Zhu 2023Cancer Pathogenesis and Therapy2023,1,2:0
