| 1 | A natural variation in Ribonuclease H-like gene underlies Rht8 to confer“Green Revolution”trait in wheat显示文摘Dear Editor,Introduction of gibberellin(GA)-insensitive Reduced height(Rht)genes,Rht-B1b and Rht-D1b,has resulted in the“Green Revolution”in modern wheat cultivars(Triticum aestivum)that has skyrocketed wheat grain yields worldwide since the 1960s(Peng et al.,1999;Velde et al.,2021).However,Rht-B1b/D1b also reduce coleoptiles,which is undesired in dryland regions where deep planting is essential for seedling establishment(Rebetzke et al.,1999,Rebetzke et al.,2001;Ellis et al.,2004). | Lingling Chai Mingming Xin Chaoqun Dong Zhaoyan Chen Huijie Zhai Junhong Zhuang Xuejiao Cheng Naijiao Wang Jia Geng Xiaobo Wang Ruolin Bian Yingyin Yao Weilong Guo Zhaorong Hu Huiru Peng Guihua Bai Qixin Sun Zhenqi Su Jie Liu Zhongfu Ni | 2022 | Molecular Plant2022，15，3： | 8 |

| 3 | Ectopic expression of VRT-A2 underlies the origin of Triticum polonicum and Triticum petropavlovskyi with long outer glumes and grains显示文摘Polish wheat (Triticum polonicum) is a unique tetraploid wheat species characterized by an elongated outer glume. The genetic control of the long-glume trait by a single semi-dominant locus, P1 (from Polish wheat), was established more than 100 years ago, but the underlying causal gene and molecular nature remain elusive. Here, we report the isolation of VRT-A2, encoding an SVP-clade MADS-box transcription factor, as the P1 candidate gene. Genetic evidence suggests that in T. polonicum, a naturally occurring sequence rearrangement in the intron-1 region of VRT-A2 leads to ectopic expression of VRT-A2 in floral organs where the long-glume phenotype appears. Interestingly, we found that the intron-1 region is a key ON/OFF molecular switch for VRT-A2 expression, not only because it recruits transcriptional repressors, but also because it confers intron-mediated transcriptional enhancement. Genotypic analyses using wheat accessions indicated that the P1 locus is likely derived from a single natural mutation in tetraploid wheat, which was subsequently inherited by hexaploid T. petropavlovskyi. Taken together, our findings highlight the promoter-proximal intron variation as a molecular basis for phenotypic differentiation, and thus species formation in Triticum plants. | Jing Liu Zhaoyan Chen Zhihui Wang Zhaoheng Zhang Xiaoming Xie Zihao Wang Lingling Chai Long Song Xuejiao Cheng Man Feng Xiaobo Wang Yanhong Liu Zhaorong Hu Jiewen Xing Zhenqi Su Huiru Peng Mingming Xin Yingyin Yao Weilong Guo Qixin Sun Jie Liu Zhongfu Ni | 2021 | Molecular Plant2021，14，9： | 4 |

| 5 | Variability of snail growing season at the Chinese Loess Plateau during the last 75 ka显示文摘Knowledge of seasonal climate change is one of the key issues facing Quaternary paleoclimatic studies and estimating seasonal climate change is difficult,especially changes such as seasonal length on glacial-interglacial timescales.The stable isotope composition from seasonal land snail shells provides the potential to reveal seasonal climatic features.Two modern land snail species,cold-aridiphilous Pupilla aeoli and thermo-humidiphilous Punctum orphana,were collected from different climatic zones in 18 localities across the Chinese Loess Plateau,spanning 11 degrees of longitude and covering a range of 1000 km2.The duration of the snail growing season(temperature ≥10℃) was shorter(202 ± 6 d) in the eastern Loess Plateau compared with in the western Loess Plateau(162 ±7 d).The δ13C of P.aeoli shells was ?9.1‰ to ?4.7‰ and ?5.0‰ to 0.3‰ for δ18O.For P.orphana,the δ13C ranged from ?9.1‰ to ?1.9‰ and ?8.9‰ to ?2.9‰ for δ18O.Both the δ13C and δ18O differences between the two snail species were reduced from the east to the western Loess Plateau(2.8‰ to 0.2 ± 1.1‰ for δ13C and 4.7‰ to 2.9 ± 1.3‰ for δ18O).These isotopic differences roughly reflect the difference in the growing season lengths between the east and west Loess Plateau indicating that the duration of the snail growing season shortens by 15 d or 19 d if the difference decreases by 1‰ in δ13C or δ18O,respectively.Thus,the difference in δ13C and δ18O between both snail species can be used to reveal the length of the snail growing season in the past.Based on our investigation,the length of the snail growing seasons from the Xifeng region during the last 75 ka was reconstructed.During the mid-Holocene(8-3 ka),the mean isotopic difference from both snail species reached maximum values of 2.6 ± 0.7‰ and 2.1 ± 1.4‰ for δ13C and δ18O,respectively.This was followed by MIS 3 that ranged from 2.5 ± 0.4‰ for δ13C and 1.6 ± 0.8‰ for δ18O.The Last Glacial Maximum changed by only 0.2‰ and 0.4‰ for δ13C and δ18O,respectively.Therefore,we estimate that the duration of the snail growing seasons to be ~200 ± 10 d during the mid-Holocene,190 ± 6 d in MIS 3 and 160 ± 3 d during the last glacial period. | HUANG LinPei WU NaiQin GU ZhaoYan CHEN XiaoYun | 2012 | Chinese Science Bulletin2012，57，9： | 1 |

| 8 | A common variant in AAK1 reduces risk of noise-induced hearing loss显示文摘Noise-induced hearing loss(NIHL)is one of the most common types of hearing loss and contributes to significant morbidity worldwide,as well as being the major cause of age-related hearing loss and tinnitus.The World Health Organization(WHO)estimates that 10%of the world's population is exposed to sound levels that could potentially cause NIHL[1].It has been widely accepted that NIHL is a multifactorial genetic disorder with estimated heritability of 36%to 40%[2].Ideally,identification of the modifying genetic variants would help protect individuals at high risk of NIHL.For decades,many geneticists have searched for genes that either predispose or protect from NIHL.Howeve r,the majority of genetic studies for NIHL were conducted in independent known candidate genes[3]. | Qixuan Wang Xueling Wang Tao Yang Lu Yang Huihui Liu Yihang Zheng Guixian Jiang Hongchao Liu Chenhui Huang Juan Chen Zhentao Wang Zhaoyan Wang Wei Zhao Jiannan Lin Xuejie Zhang Junbo Shi Kun Han Xingyu Le Yan Ren Yun Li Yingying Hong Wentao Shi Dongqi Cui Minfei Qian Jun Xu Xiaofei Zheng Yunge Gao Chen Li James Lin Zhiwu Huang Hao Wu | 2023 | National Science Review2023，10，7： | 0 |
| 9 | Chinese Fetal Growth:A Multicenter Cohort Study Based on Fetal Ultrasound Measurements显示文摘Objective:To build a reference fetal growth chart for the Chinese population based on fetal ultrasound measurements.Methods:This was a multicenter,population-based retrospective cohort study.Longitudinal ultrasound measurement data were collected from 24 hospitals in 18 provinces of China from 1st September through 31st October of 2019.The estimated fetal weight(EFW)was calculated based on head circumference,abdominal circumference,and femur length using Hadlock formula 3.Fetal growth curves were estimated using a two-level linear regression model with cubic splines.All participants were divided into two groups:the northern group(n=5829)and the southern group(n=3246)based on the geographical division of China and male fetus group(n=4775)and female fetus group(n=4300)based on fetal gender.The EFW was compared by fetal gender and geographical group.All statistical models were adjusted for maternal sociodemographic characteristics.Results:A total of 9075 participants with 31,700 ultrasound measurement records were included in this study.Male fetuses demonstrated significantly larger EFW compared to female ones starting at 16 weeks of gestation and extending to delivery(global testP<0.01).The overall geographic difference in EFW was significant(global testP=0.03),and week-specific comparisons showed that the northern group had a greater EFW starting at 15 weeks of gestation and extending to 29 weeks of gestation,although this difference did not extend to the time of delivery.TheZ-score of EFW confirmed that our Chinese fetal growth charts differed from previously published standards.Conclusion:This study provides EFW and ultrasound biometric reference measurements for Chinese fetuses and reveals differences from other fetal growth charts.The chart is worth promoting in more regions of China but should be tested prudently before use. | Xiaoli Gong Tianchen Wu Xiaoli Wang Lizhen Zhang Yiping You Hongwei Wei Xifang Zuo Ying Zhou Xinli Xing Zhaoyan Meng Qi Lyu Zhaodong Liu Jian Zhang Liyan Hu Junnan Li Li Li Chulin Chen Chunyan Liu Guoqiang Sun Aiju Liu Jingsi Chen Yuan Lyu Yuan Wei Yangyu Zhao | 2023 | Maternal-Fetal Medicine2023，5，1： | 0 |
| 10 | Genome-wide linkage mapping of QTL for root hair length in a Chinese common wheat population显示文摘Root hairs are fast growing,ephemeral tubular extensions of the root epidermis that aid nutrient and water uptake.The aim of the present study was to identify QTL for root hair length(RHL)using 227 F8 recombinant inbred lines(RILs)derived from a cross of Zhou 8425 B(Z8425 B)and Chinese Spring(CS),and to develop convenient molecular markers for markerassisted breeding in wheat.Analysis of variance of root hair length showed significant differences(P<0.01)among RILs.The genetic map for QTL analysis consisted of 3389 unique SNP markers.Using composite interval mapping,four major QTL(LOD>2.5)for RHL were identified on chromosomes 1 B(2),2 D and 6 D and four putative QTL(2≤LOD≤2.5)were detected on chromosomes 1 A,3 A,6 B,and 7 B,explaining 3.32%–6.52%of the phenotypic variance.The positive alleles for increased RHL of QTL on chromosomes 2 D,6 B and 6 D(QRhl.cau-2 D,q Rhl.cau-6 B,and QRhl.cau-6 D)were contributed by Z8425 B,and CS contributed positive QTL alleles on chromosomes 1 A(q Rhl.cau-1 A),1 B(QRhl.cau-1 B.1 and QRhl.cau-1 B.2),3 A(q Rhl.cau-3 A)and 7 B(q Rhl.cau-7 B).STARP markers were developed for QRhl.cau-1 B.1,QRhl.cau-2 D,QRhl.cau-6 D,and q Rhl.cau-7 B.Haplotype and association analysis indicated that the positive allele of QRhl.cau-6 D had been strongly selected in Chinese wheat breeding programs.Collectively,the identified QTL for root hair length are likely to be useful for marker-assisted selection. | Feng Huang Zhaoyan Chen Dejie Du Panfeng Guan Lingling Chai Weilong Guo Zhaorong Hu Mingming Xin Huiru Peng Yingyin Yao Zhongfu Ni | 2020 | The Crop Journal2020，8，6： | 0 |
| 11 | TaACTIN7-D regulates plant height and grain shape in bread wheat显示文摘Exploitation of new gene resources and genetic networks contributing to the control of crop yield-related traits,such as plant height,grain size,and shape,may enable us to breed modern high-yielding wheat varieties through molecular methods.In this study,via ethylmethanesulfonate mutagenesis,we identify a wheat mutant plant,mu-597,that shows semi-dwarf plant architecture and round grain shape.Through bulked segregant RNA-seq and map-based cloning,the causal gene for the semi-dwarf phenotype of mu-597 is located.We find that a single-base mutation in the coding region of TaACTIN7-D(TaACT7-D),leading to a Gly-to-Ser(G65S)amino acid mutation at the 65th residue of the deduced TaACT7-D protein,can explain the semi-dwarfism and round grain shape of mu-597.Further evidence shows that the G65S mutation in TaACT7-D hinders the polymerization of actin from monomeric(G-actin)to filamentous(F-actin)status while attenuates wheat responses to multiple phytohormones,including brassinosteroids,auxin,and gibberellin.Together,these findings not only define a new semi-dwarfing gene resource that can be potentially used to design plant height and grain shape of bread wheat but also establish a direct link between actin structure modulation and phytohormone signal transduction. | Xiongtao Li Beilu Cao Dejie Du Long Song Lulu Tian Xiaoming Xie Zhaoyan Chen Yanpeng Ding Xuejiao Cheng Yingyin Yao Weilong Guo Zhenqi Su Qixin Sun Zhongfu Ni Lingling Chai Jie Liu | 2023 | Journal of Genetics and Genomics2023，50，11： | 0 |
| 12 | SecReT6 update:a comprehensive resource of bacterial TypeⅥSecretion Systems显示文摘TypeⅥSecretion System(T6SS)plays significant roles in microbial activities via injecting effectors into adjacent cells or environments.T6SS increasingly gained attention due to its important influence on pathogenesis,microbial competition,etc.T6SS-associated research is explosively expanding on numerous grounds that call for an efficient resource.The SecReT6 version3 provides comprehensive information on T6SS and the interactions between T6SS and T6SS-related proteins such as T6SS regulators and T6SS effectors.To assist T6SS researches like microbial competition and regulatory mechanisms,SecReT6 v3developed online tools for detection and analysis of T6SS and T6SS-related proteins and estimation of T6SS-dependent killing risk.We have identified a novel T6SS regulator and T6SS-dependent killing capacity in Acinetobacter baumannii clinical isolates with the aid of SecReT6 v3.17,212 T6SSs and plentiful T6SS-related proteins in 26,573 bacterial complete genomes were also detected,analyzed and incorporated into the database.The database is freely available at https://bioinfo-mml.sjtu.edu.cn/SecReT6/. | Jianfeng Zhang Jiahao Guan Meng Wang Gang Li Marko Djordjevic Cui Tai Hui Wang Zixin Deng Zhaoyan Chen Hong-Yu Ou | 2023 | Science China(Life Sciences)2023，66，3： | 0 |
| 13 | Variable Curvature Modeling Method of Soft Continuum Robots with Constraints显示文摘The inherent compliance of continuum robots holds great promise in the fields of soft manipulation and safe human–robot interaction.This compliance reduces the risk of damage to the manipulated object and its surroundings.However,continuum robots possess theoretically infinite degrees of freedom,and this high flexibility usually leads to complex deformations when subjected to external forces and positional constraints.Describing these complex deformations is the main challenge in modeling continuum robots.In this study,we investigated a novel variable curvature modeling method for continuum robots,considering external forces and positional constraints.The robot configuration curve is described using the developed mechanical model,and then the robot is fitted to the curve.A ten-section continuum robot prototype with a length of 1 m was developed in order to validate the model.The feasibility and accuracy of the model were verified by the ability of the robot to reach target points and track complex trajectories with a load.This work was able to serve as a new perspective for the design analysis and motion control of continuum robots. | Yuwang Liu Wenping Shi Peng Chen Liang Cheng Qing Ding Zhaoyan Deng | 2023 | Chinese Journal of Mechanical Engineering2023，36，6： | 0 |
| 14 | The TaTCP4/10-B1 cascade regulates awn elongation in wheat(Triticum aestivum L.)显示文摘Awns are important morphological markers for wheat and exert a strong physiological effect on wheat yield.The awn elongation suppressor B1 has recently been cloned through association and linkage analysis in wheat.However,the mechanism of awn inhibition centered around B1 remains to be clarified.Here,we identified an allelic variant in the coding region of B1 through analysis of re-sequencing data;this variant causes an amino acid substitution and premature termination,resulting in a long-awn phenotype.Transcriptome analysis indicated that B1 inhibited awn elongation by impeding cytokinin-and auxinpromoted cell division.Moreover,B1 directly repressed the expression of TaRAE2 and TaLks2,whose orthologs have been reported to promote awn development in rice or barley.More importantly,we found that TaTCP4 and TaTCP10 synergistically inhibited the expression of B1,and a G-to-A mutation in the B1 promoter attenuated its inhibition by TaTCP4/10.Taken together,our results reveal novel mechanisms of awn development and provide genetic resources for trait improvement in wheat. | Wensheng Ke Jiewen Xing Zhaoyan Chen Yidi Zhao Weiya Xu Lulu Tian Jinquan Guo Xiaoming Xie Dejie Du Zihao Wang Yufeng Li Jin Xu Mingming Xin Weilong Guo Zhaorong Hu Zhenqi Su Jie Liu Huiru Peng Yingyin Yao Qixin Sun Zhongfu Ni | 2023 | Plant Communications2023，4，4： | 0 |
