关于水稻稻瘟病病原菌学名的正确使用

引起水稻稻瘟病的病原真菌历来被认为是Pyricularia oryzae Cavara,以前曾将属名写成Piricularia,1958年Hughes查考Saccardo(1880)定名时使用的属名是Pyricularia,后人误写为Piricularia,与原发表的不符,按照国际植物命名的法规,应订正为Pyricularia oryzac Cavgra,这一学名一直沿用至今(孙漱沅等,1986)。根据Rossman et al(1990)考证,Saccardo(1880)在描     

Import of Rift Valley fever to China: a potential new threat?

In vivo tunable CRISPR mediates efficient somatic mutagenesis to generate tumor models

Dear Editor, CRISPR/Cas9 has revolutionized genome editing technology due to its simplicity and robustness (Mali et al., 2013). Several inducible CRISPR/Cas9 systems recently developed make spatiotemporal genome editing possible (Kon ermann et al., 2013;Balboa et al., 2015;Dow et al., 2015;Zetsche et al., 2015;Liu et al., 2016;Kleinjan et al., 2017;Maji et al.. 2017;Senturk et al., 2017;Lu et al., 2018).

Cotton variant genomes—a breakthrough in population genetics analysis

正Cotton is not only an important cash crop for its fiber,but also an excellent model system for studying polyploidization,cell elongation and cell wall biosynthesis(Yang et al.,2014;Fang et al.,2017;Wang et al.,2016;Zou et al.,2016).A focus for scientists is to dissect the genetic basis underlying important agronomic traits(Gong et al.,2018;Huang et al.,2016).The advent of high-throughput sequencing technologies has boosted unveiling the cotton genome(Wang et al.,2012;Li et al.,2014;Li et al.,2015).High-throughput     

Generation of marker-free transgenic rice using CRISPR/Cas9 system controlled by ?oral speci?c promoters

Recently, the CRISPR/Cas9 system has been used as a powerful tool for genome editing in many species (Jinek et al., 2012;Cong et al., 2013;Wright et al., 2016;Li et al., 2017;Deng et al., 2018). The CR1SPR/Cas9 system can not only be used as a useful technology to disrupt endogenous genes but also expand numerous other applications, such as precise base editing (Komor et al., 2016;Zong et al., 2017), regulation of gene expression (Gilbert et al., 2013), and gene replacement or insertion (Wang et al., 2017).     

Interaction between Bms1 and Rcl1,two ribosome biogenesis factors,is evolutionally conserved in zebrafish and human

正Ribosomes are large RNA and protein complexes that function as the machinery for translation protein synthesis(Boisvert et al.,2007;Ben-Shem et al.,2011;Henras et al.,2015;Khatter et al.,2015;McCann et al.,2015).The eukaryotic ribosome is composed of two subunits,the 60S large subunit(LSU)and the 40S small subunit(SSU),which collectively comprise of four different ribosomal RNA(rRNA)species and more than 70 proteins(Ben-Shem et al.,2011;Henras et al.,2015;Khatter et al.,2015).The LSU contains

SOCS-3 contributes to bisphenol a exposure-induced insulin resistance in hepatocytes

<正>Dear Editor,Bisphenol A (BPA), a common and widely used monomer in the production of polycarbonate plastics and epoxy resin,(Healy et al., 2015; De Filippis et al., 2018) has been defined as an endocrine disrupting chemical (EDC) associated with the etiology of insulin resistance (IR)(Gioiosa et al., 2015;Wei et al., 2017) and metabolic disorders (Padmanabhan et al., 2010; Fang et al., 2015; Balistrieri et al., 2018).

Breeding cotton with superior fiber quality: identification and utilization of multiple elite loci and exotic genetic resources

正In the last decade, cotton genomics had great progress in genome assembling(Li et al., 2015; Huang et al., 2020) and agriculturally important locus identification(Du et al., 2018;Ma et al., 2018; Li et al., 2021).Upland cotton(Gossypium hirsutum) is one of the most important cash crops cultivated worldwide. The fiber quality of cotton directly determines its economic value, and therefore enhancing fiber quality is always the primary task in cotton breeding practices(Xia et al., 2019; Huang et al.,2021).     

Resident endothelial cells generate hepatocytes through cell fusion in adult mouse liver

正Unravelling lineage plasticity and cellular contribution to hepatocytes provides valuable information for understanding sources that fuel homeostatic renewal of the liver(Miyajima et al.,2014).In the adult stage,hepatocytes are mainly self-renewed through cell division(Schaub et al.,2014;Tarlow et al.,2014;Yanger et al.,2014).Under severe injury or when hepatocyte proliferation is significantly impaired,cholangiocytes or biliary epithelial cells contribute to hepatocytes(Raven et al.,2017;Deng et al.,2018).It

Highly efficient genome editing using oocyte-specific zcas9 transgenic zebrafish

Novel Recombinant Seneca Valley Virus Isolated from Slaughtered Pigs in Guangdong Province

<正>Dear Editor,Since the first outbreak in Brazil in 2015, Seneca Valley virus(SVV) associated with porcine idiopathic vesicular disease,has shown increasing geographic distribution. Cases of SVV have been reported from several countries including the United States (US), Colombia, Thailand, Canada, and China(Pasma et al. 2008; Zhang et al. 2015; Sun et al. 2017; Wu et al. 2017; Liu et al. 2018; Saeng-Chuto et al. 2018).

Persisting lung pathogenesis and minimum residual virus in hamster after acute COVID-19

Dear Editor,Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)has infected more than 200 million people,causing coronavirus disease 2019(COVID-19)worldwide.Lungs are the primary target organ of SARS-CoV-2 infection.The mild COVID-19 cases develop symptoms of fever,fatigue,muscle weakness,chest pain,headache and cough(Chen et al.,2020;Wang et al.,2020;Zhu et al.,2020),while severe COIVD-19 cases might have pneumonia,breathing difficulties,multiple organ failure and death(Chen et al.,2020;Wang et al.,2020;Zhu et al.,2020).Both the clinicians and researchers have largely focused on the acute phase of COVID-19,but the long-term health consequences of the COVID-19 patients after clinical recovery remain less investigated.Several clinical cohorts demonstrated that some patients discharged from hospital still experience symptoms including fatigue,muscle weakness,chest pain,cough and breathing difficulties(Carfi et al.,2020;Lim et al.,2020;Huang et al.,2021).Moreover,severely impaired pulmonary diffusion capacities and abnormal chest imaging manifestations were observed in some convalescent patients(Huang et al.,2021).Surprisingly,residual virus(An et al.,2020;Yao et al.,2020;Kim et al.,2021)were detected in some convalescent patients.

Strengthening the functional research on the interaction between host genes and microbiota

正In recent years, many studies have focused on the interaction between host genes and microbiota and their mutual influence (Bonder et al., 2016; Goodrich et al., 2014; Rothschild et al., 2018; Wang et al., 2016; Zhang et al., 2019). Host genetic variation influences the composition of the microbial community, for instance in inflammatory bowel disease, host genetic susceptibilities induce pathological shifts in micro-
