| 1 | Tissue differential expression of lycopene β-cyclase gene in papaya显示文摘Carotene pigments in flowers and fruits are distinct features related to fitness advantages such as attracting insects forpollination and birds for seed dispersal.In papaya,the flesh color of the fruit is considered a quality trait that correlateswith nutritional value and is linked to shelf-life of the fruit.To elucidate the carotenoid biosynthesis pathway in papaya,we took a candidate gene approach to clone the lycopene β-cyclase gene,LCY-B.A papaya LCY-B ortholog,cpLCY-B,was successfully identified from both cDNA and bacterial artificial chromosome(BAC)libraries and complete genomicsequence was obtained from the positive BAC including the promoter region.This cpLCY-B shared 80% amino acididentity with citrus LCY-B.However,full genomic sequences from both yellow- and red-fleshed papaya were identical.Quantitative real-time PCR(qPCR)revealed similar levels of expression at six different maturing stages of fruits forboth yellow-and red-fleshed genotypes.Further expression analyses of cpLCY-B showed that its expression levels wereseven- and three-fold higher in leaves and,respectively,flowers than in fruits,suggesting that cpLCY-B is down-regulatedduring the fruit ripening process. | Rachel L Skelton Qingyi Yu Rajeswari Srinivasan Richard Manshardt Paul H Moore Ray Ming | 2006 | Cell Research2006，16，8： | 8 |
| 2 | Cloning and characterization of a FLORICAULA/LEAFY ortholog, PFL, in polygamous papaya显示文摘The homologous genes FLORICAULA (FLO) in Antirrhinum and LEAFY (LFY) in Arabidopsis are known to regu- late the initiation of flowering in these two distantly related plant species. These genes are necessary also for the expression of downstream genes that control floral organ identity. We used Arabidopsis LFY cDNA as a probe to clone and sequence a papaya ortholog of LFY, PFL. It encodes a protein that shares 61% identity with the Arabidopsis LFY gene and 71% identity with the LFY homologs of the two woody tree species: California sycamore (Platanus racemosa) and black cottonwood (Populus trichocarpa). Despite the high sequence similarity within two conserved regions, the N-terminal proline-rich motif in papaya PFL differs from other members in the family. This difference may not affect the gene function of papaya PFL, since an equally divergent but a functional LFY ortholog NEEDLY of Pinus radiata has been reported. Genomic and BAC Southern analyses indicated that there is only one copy of PFL in the papaya genome. In situ hybridization experiments demonstrated that PFL is expressed at a relatively low level in leaf primordia, but it is expressed at a high level in the floral meristem. Quantitative PCR analyses revealed that PFL was expressed in flower buds of all three sex types - male, female, and hermaphrodite with marginal difference between hermaphrodite and unisexual flowers. These data suggest that PFL may play a similar role as LFY in flower development and has limited effect on sex differentiation in papaya. | Qingyi YU Paul H. MOORE Henrik H. ALBERT Adrienne H.K.

| 7 | PGD: Pineapple Genomics Database显示文摘Pineapple occupies an important phylogenetic position as its reference genome is a model for studying the evolution the Bromeliaceae family and the crassulacean acid metabolism(CAM)photosynthesis.Here,we developed a pineapple genomics database(PGD,http://gffzzf3bb806060964046hqno0v0qvn9kp6b06.ffgz.tsg.suse.edu.cn/pineapple/html/index.html)as a central online platform for storing and integrating genomic,transcriptomic,function annotation and genetic marker data for pineapple(Ananas comosus(L.)Merr.).The PGD currently hosts significant search tools and available datasets for researchers to study comparative genomics,gene expression,gene co-expression molecular marker,and gene annotation of A.comosus(L).PGD also performed a series of additional pages for a genomic browser that visualizes genomic data interactively,bulk data download,a detailed user manual,and data integration information.PGD was developed with the capacity to integrate future data resources,and will be used as a long-term and open access database to facilitate the study of the biology,distribution,and the evolution of pineapple and the relative plant species.An email-based helpdesk is also available to offer support with the website and requests of specific datasets from the research community. | Huimin Xu Qingyi Yu Yan Shi Xiuting Hua Haibao Tang Long Yang Ray Ming Jisen Zhang | 2018 | Horticulture Research2018，5，1： | 0 |
| 8 | Confining carbon dots in amino-functionalized mesoporous silica:n→π^(*) interaction triggered deep-red solid-state fluorescence显示文摘Deep-red and near-infrared emissive carbon dots(CDs)are highly desired for bioimaging,especially in deep tissue imaging,but they are extremely rare and the known ones usually suffer from low-efficient fluorescence in water and aggregation-induced fluorescence quenching in solid state.In this work,CDs with intriguing solvent-dependent and two-photon fluorescence emissions have been prepared by a facile solvothermal method.Detailed characterizations reveal that there is an n→π*interaction between the carboxyl functional groups on CDs and the electron donor groups in solvent,which leads to the increase of energy density of CDs and the decrease of energy level,resulting in the red shift of luminescence with enhanced electron donating ability of solvent.Inspired by this finding,mesoporous silica nanoparticles(MSNs)with suitable pore size and low biological toxicity are modified by amino groups to confine CDs,thus the deep-red fluorescence emission is achieved both in solid state and in water facilitated by the n→π*interaction of host-guest.The as-prepared CDs@EDA-MSN composite exhibits high-efficient fluorescence with 650 nm wavelength,low toxicity,and good biocompatibility,which endow them a promising application in bio-imaging. | Hongyue Zhang Qingyi Li Shuo Wang Xiaowei Yu Bolun Wang Guangrui Chen Li Ren Jiyang Li Mingxing Jin Jihong Yu | 2023 | Nano Research2023，16，3： | 0 |
| 9 | Expert consensus on prevention and cardiopulmonary resuscitation for cardiac arrest in COVID-19显示文摘Background:Cardiopulmonary resuscitation(CPR)strategies in COVID-19 patients differ from those in patients suffering from cardiogenic cardiac arrest.During CPR,both healthcare and non-healthcare workers who provide resuscitation are at risk of infection.The Working Group for Expert Consensus on Prevention and Cardiopulmonary Resuscitation for Cardiac Arrest in COVID-19 has developed this Chinese Expert Consensus to guide clinical practice of CPR in COVID-19 patients.Main recommendations:1)A medical team should be assigned to evaluate severe and critical COVID-19 for early monitoring of cardiac-arrest warning signs.2)Psychological counseling and treatment are highly recommended,since sympathetic and vagal abnormalities induced by psychological stress from the COVID-19 pandemic can induce cardiac arrest.3)Healthcare workers should wear personal protective equipment(PPE).4)Mouth-to-mouth ventilation should be avoided on patients suspected of having or diagnosed with COVID-19.5)Hands-only chest compression and mechanical chest compression are recommended.6)Tracheal-intubation procedures should be optimized and tracheal-intubation strategies should be implemented early.7)CPR should be provided for 20-30 min.8)Various factors should be taken into consideration such as the interests of patients and family members,ethics,transmission risks,and laws and regulations governing infectious disease control.Changes in management:The following changes or modifications to CPR strategy in COVID-19 patients are proposed:1)Healthcare workers should wear PPE.2)Hands-only chest compression and mechanical chest compression can be implemented to reduce or avoid the spread of viruses by aerosols.3)Both the benefits to patients and the risk of infection should be considered.4)Hhealthcare workers should be fully aware of and trained in CPR strategies and procedures specifically for patients with COVID-19. | Wei Song Jie Wei Xiangdong Jian Deren Wang Yanhong Ouyang Yuanshui Liu Xianjin Du Ying Chen Yingqi Zhang Heping Xu Shuming Xianyu Qiong Ning Xiang Li Xiaotong Han Feng Zhan Tao Yu Wenteng Chen Jun Zhang Wenwei Cai Sheng’ang Zhou Shengyang Yi Yu Cao Xiaobei Chen Shunjiang Xu Zong’an Liang Duohu Wu Fen Ai Zhong Wang Qingyi Meng Yuhong Mi Sisen Zhang Rongjia Yang Shouchun Yan Wenbin Han Yong Lin Chuanyun Qian Wenwu Zhang Yan Xiong Jun Lv Baochi Liu Yan Cao Xiaojun He Xuelian Sun Yufang Cao Tian’en Zhou | 2021 | Asian Pacific Journal of Tropical Medicine2021，14，6： | 0 |

| 11 | Sex biased expression of hormone related genes at early stage of sex differentiation in papaya flowers显示文摘Sex types of papaya are controlled by a pair of nascent sex chromosomes,but molecular genetic mechanisms of sex determination and sex differentiation in papaya are still unclear.We performed comparative analysis of transcriptomic profiles of male and female floral buds at the early development stage before the initiation of reproductive organ primordia at which there is no morphological difference between male and female flowers.A total of 1734 differentially expressed genes(DEGs)were identified,of which 923 showed female-biased expression and 811 showed male-biased expression.Functional annotation revealed that genes related to plant hormone biosynthesis and signaling pathways,especially in abscisic acid and auxin pathways,were overrepresented in the DEGs.Transcription factor binding motifs,such as MYB2,GAMYB,and AP2/EREBP,were enriched in the promoters of the hormone-related DEGs,and transcription factors with those motifs also exhibited differential expression between sex types.Among these DEGs,we also identified 11 genes in the non-recombining region of the papaya sex chromosomes and 9 genes involved in stamen and carpel development.Our results suggested that sex differentiation in papaya may be regulated by multiple layers of regulation and coordination and involved transcriptional,epigenetic,and phytohormone regulation.Hormones,especially ABA and auxin,transcription factors,and genes in the non-recombination region of the sex chromosome could be involved in this process.Our findings may facilitate the elucidation of signal transduction and gene interaction in sex differentiation of unisexual flowers in papaya. | Juan Liu Li-Yu Chen Ping Zhou Zhenyang Liao Hai Lin Qingyi Yu Ray Ming | 2021 | Horticulture Research2021，8，1： | 0 |
