| 1 | A Strigolactone Biosynthesis Gene Contributed to the Green Revolution in Rice显示文摘Plant architecture is a complex agronomic trait and a major factor of crop yield,which is affected by several important hormones.Strigolactones(SLs)are identified as a new class hormoneinhibiting branching in many plant species and have been shown to be involved in various developmental processes.Genetical and chemical modulation of the SL pathway is recognized as a promising approach to modify plant architecture.However,whether and how the genes involved in the SL pathway could be utilized in breeding still remain elusive.Here,we demonstrate that a partial loss-of-function allele of the SL biosynthesis gene,HIGH TILLERING AND DWARF 1/DWARF17(HTD1/D17),which encodes CAROTENOID CLEAVAGE DIOXYGENASE 7(CCD7),increases tiller number and improves grain yield in rice.We found that the HTD1 gene had been widely utilized and co-selected with Semidwarf 1(SD1),both contributing to the improvement of plant architecture in modern rice varieties since the Green Revolution in the 1960s.Understanding how phytohormone pathway genes regulate plant architecture and how they have been utilized and selected in breeding will lay the foundation for developing the rational approaches toward improving crop yield. | Yuexing Wang Lianguang Shang Hong Yu Longjun Zeng Jiang Hu Shen Ni Yuchun Rao Sanfeng Li Jinfang Chu Xiangbing Meng Lei Wang Ping Hu Jijun Yan Shujing Kang Minghao Qu Hai Lin Tao Wang Quan Wang Xingming Hu Hongqi Chen Bing Wang Zhenyu Gao Longbiao Guo Dali Zeng Xudong Zhu Guosheng Xiong Jiayang Li Qian Qian | 2020 | Molecular Plant2020，13，6： | 23 |
| 2 | Testing coral paleothermometers(B/Ca, Mg/Ca, Sr/Ca, U/Ca and δ^(18)O) under impacts of large riverine runoff显示文摘Sea surface temperature(SST) proxies including B/Ca, Mg/Ca, Sr/Ca, U/Ca and δ18O were analyzed in the skeleton of a Porites coral collected from the Zhujiang River(Pearl River) Estuary(ZRE). These geochemical proxies are influenced by river runoff and this area of the northern South China Sea is strongly affected by seasonal freshwater floods. We assessed the robustness of each SST proxy through comparison with the local instrumental SST. Coral Sr/Ca shows the highest correlation with SST variations(r2=0.59), suggesting Sr/Ca is the most robust SST proxy. In contrast, coral δ18O(r2=0.46), B/Ca(r2=0.43) and U/Ca(r2=0.41) ratios were only moderately correlated with SST variations, suggesting that they are disturbed by some other factors in addition to SST. The poor correlation(r2=0.27) between SST and Mg/Ca indicates that Mg/Ca in coral skeletons is not a simple function of SST variations. This may ultimately limit the use of Mg/Ca as a coral paleothermometer. | CHEN Tianran YU Kefu ZHAO Jianxin YAN Hongqiang SONG Yinxian FENG Yuexing CHEN Tegu | 2015 | Acta Oceanologica Sinica2015，34，8： | 4 |
| 3 | Effects of Different Selenium Application Methods on Wheat (Triticum aestivum L.) Biofortification and Nutritional Quality显示文摘Mineral nutrient malnutrition,especially deficiency in selenium(Se),affects the health of approximately 1 billion people worldwide.Wheat,a staple food crop,plays an important role in producing Se-enriched foodstuffs to increase the Se intake of humans.This study aimed to evaluate the effects of different Se application methods on grain yield and nutritional quality,grain Se absorption and accumulation,as well as 14 other trace elements concentrations in wheat grains.A sand culture experiment was conducted via a completely randomized 3×2×1 factorial scheme(three Se levels×two methods of Se application,foliar or soil×one Se sources,selenite),with two wheat cultivars(Guizi No.1,Chinese Spring).The results showed that both foliar Se and soil Se application methods had effects on wheat pollination.Foliar Se application resulted in early flowering of wheat,while soil Se application caused early flowering of wheat at low Se levels(5 mg kg^(−1))and delayed wheat flowering at high selenium levels(10 mg kg^(−1)),respectively.For trace elements,human essential trace elements(Fe,Zn,Mn,Cu,Cr,Mo,Co and Ni)concentrations in wheat grains were dependent of Se applica-tion methods and wheat cultivars.However,toxic trace elements(Cd,Pb,Hg,As,Li and Al)concentrations can be decreased by both methods,indicating a possible antagonistic effect.Moreover,both methods increased Se concentrations,and improved grain yield and nutritional quality,while the foliar application was better than soil.Accordingly,this study provided useful information concerning nutritional biofortification of wheat,indicating that it is feasible to apply Se to conduct Se biofortification,inhibit the heavy metal elements concentrations and improve yield and quality in crops,which caused human health benefits. | Yong Liang Yuexing Chen Dong Liu Jianping Cheng Gang Zhao Tzion Fahima Jun Yan | 2020 | Phyton-International Journal of Experimental Botany2020，89，2： | 1 |

| 6 | Effectiveness of quality of care for patients with type 2 diabetes in China:findings from the Shanghai Integration Model(SIM)显示文摘This cross-sectional study aimed to investigate the quality of care of diabetes in Shanghai,China.A total of 173235 patients with type 2 diabetes in 2017 were included in the analysis.Profiles of risk factors and intermediate outcomes were determined.The patients had a mean age of 66.43±8.12(standard deviation(SD))years and a mean diabetes duration of 7.95±5.53(SD)years.The percentage of patients who achieved the target level for HbA_(1c)(<7.0%)was 48.6%.Patients who achieved the target levels for blood pressure(BP)<130/80 mmHg and low-density lipoprotein-cholesterol(LDL-c)<2.6 mmol/L reached 17.5%and 34.0%,respectively.A total of 3.8%achieved all three target levels,and the value increased to 6.8%with an adaptation of the BP target level(<140/90 mmHg)for those over 65 years.Multivariable analysis identified the factors associated with a great likelihood of achieving all three target levels:male,young age,short diabetes duration,low body mass index,macrovascular complications,no microvascular complications,prescribed with lipid-lowering medication,and no prescription of antihypertensive medication.In conclusion,nearly 50%and one-third of the patients with diabetes met the target levels for HbA_(1c)and LDL-c,respectively,with a low percentage achieving the BP target level.The percentage of patients who achieved all three target levels needs significant improvement. | Chun Cai Yuexing Liu Yanyun Li Yan Shi Haidong Zou Yuqian Bao Yun Shen Xin Cui Chen Fu Weiping Jia the SIM Study Group | 2022 | Frontiers of Medicine2022，16，1： | 1 |
| 7 | Identification of natural allelic variation in TTL1 controlling thermotolerance and grain size by a rice super pan-genome∞显示文摘Continuously increasing global temperatures present great challenges to food security.Grain size,one of the critical components determining grain yield in rice(Oryza sativa L.),is a prime target for genetic breeding.Thus,there is an immediate need for genetic improvement in rice to maintain grain yield under heat stress.However,quantitative trait loci(QTLs)endowing heat stress tolerance and grain size in rice are extremely rare.Here,we identified a novel negative regulator with pleiotropic effects,Thermo‐Tolerance and grain Length 1(TTL1),from the super pan‐genomic and transcriptomic data.Loss‐of‐function mutations in TTL1 enhanced heat tolerance,and caused an increase in grain size by coordinating cell expansion and proliferation.TTL1 was shown to function as a transcriptional regulator and localized to the nucleus and cell membrane.Furthermore,haplotype analysis showed that hapL and hapS of TTL1 were obviously correlated with variations of thermotolerance and grain size in a core collection of cultivars.Genome evolution analysis of available rice germplasms suggested that TTL1 was selected during domestication of the indica and japonica rice subspecies,but still had much breeding potential for increasing grain length and thermotolerance.These findings provide insights into TTL1 as a novel potential target for the development of high‐yield and thermotolerant rice varieties. | Yarong Lin Yiwang Zhu Yuchao Cui Hongge Qian Qiaoling Yuan Rui Chen Yan Lin Jianmin Chen Xishi Zhou Chuanlin Shi Huiying He Taijiao Hu Chenbo Gu Xiaoman Yu Xiying Zhu Yuexing Wang Qian Qian Cuijun Zhang Feng Wang Lianguang Shang | 2023 | Journal of Integrative Plant Biology2023，65，12： | 0 |
| 8 | Inductorless CMOS Low Noise Amplifier for Multiband Application in 0.1–1.2 GHz显示文摘A 0.18 μm CMOS low noise amplifier(LNA) by utilizing noise-canceling technique was designed and implemented in this paper. Current-reuse and self-bias techniques were used in the first stage to achieve input matching and reduce power consumption. The core size of the proposed CMOS LNA circuit without inductor was only 128 μm 9226 μm. The measured power gain and noise figure of the proposed LNA were 20.6 and 1.9 dB,respectively. The 3-dB bandwidth covers frequency from 0.1 to 1.2 GHz. When the chip was operated at a supply voltage of 1.8 V, it consumed 25.69 mW. The high performance of the proposed LNA makes it suitable for multistandard low-cost receiver front-ends within the above frequency range. | Guoxuan Qin Mengmeng Jin Guoping Tu Yuexing Yan Laichun Yang Yanmeng Xu Jianguo Ma | 2017 | Transactions of Tianjin University2017，23，2： | 0 |
