| 1 | A Rare Allele of GS2 Enhances Grain Size anc Grain Yield in Rice显示文摘谷物尺寸决定谷物重量并且影响谷物质量。调整谷物尺寸的几主要量的特点 loci (QTL ) 被克隆;然而,我们调整米饭谷物的尺寸的内在的机制的理解仍然保持碎片。这里,我们报导克隆和主导的 QTL 的描述,染色体 2 上的谷物尺寸(GS2 ) 编码调整生长的因素 4,一个 transcriptional 管理者。GS2 本地化到原子核并且可以充当抄写使活跃之物。影响 microRNA 的有约束力的地点的 GS2 的一个稀罕变化, OsmiR396c,原因提高了 GS2/OsGRF4 的表示。GS2 表示的增加导致更大的房间和房间的增加的数字,它因此提高谷物重量和产量。进米饭栽培变种的 GS2/OsGRF4 的这稀罕等位基因的介绍能显著地提高谷物重量和增加谷物产量,用在引起产量很高的米饭变化的可能的应用。 | Jiang Hu Yuexing Wang Yunxia Fang Longjun Zeng Jie Xu Haiping Yu Zhenyuan Shi Jiangjie Pan Dong Zhang Shujing Kang Li Zhu Guojun Dong Longbiao Guo Dali Zeng Guangheng Zhang Lihong Xie Guosheng Xiong Jiayang Li Qian Qian | 2015 | Molecular Plant2015，8，10： | 57 |
| 2 | Control of Bird Feeding Behavior by Tannin1 through Modulating the Biosynthesis of Polyphenols and Fatty Acid-Derived Volatiles in Sorghum显示文摘Bird predation during seed maturation causes great loss to agricultural production.In this study,through GWAS analysis of a large-scale sorghum germplasm diversity panel,we identified that Tannin1,which encodes a WD40 protein functioning in the WD40/MYB/bHLH complex,controls bird feeding behavior in sorghum.Metabolic profiling analysis showed that a group of sorghum accessions preferred by birds contain mutated tan1-a/b alleles and accumulate significantly lower levels of anthocyanins and condensed tannin compounds.In contrast,a variety of aromatic and fatty acid-derived volatiles accumulate at significantly higher levels in these bird-preference accessions.We subsequently conducted both sparrow feeding and sparrow volatile attractant assays,which confirmed,respectively,the antifeedant and attractant functions of these differentially accumulated metabolites.In addition,the connection between the biosynthesis pathway of anthocyanin and proanthocyanidin and the pathway of fatty acid–derived volatile biosynthesis was demonstrated by discovering that Tannin1 complex modulates fatty acid biosynthesis by regulating the expression of SbGL2 in sorghum,thus affecting the accumulation of fatty acid-derived volatiles.Taken together,our study identified Tannin1 as the gene underlying the major locus controlling bird feeding behavior in sorghum,illustrating an example of the identification of an ecologically impactful molecular mechanism from field observation and providing significant insights into the chemistry of bird–plant ecological interactions. | Peng Xie Jiayang Shi Sanyuan Tang Chengxuan Chen Aimal Khan Fengxia Zhang Ying Xiong Chao Li Wei He Guodong Wang Fumin Lei Yaorong Wu Qi Xie | 2019 | Molecular Plant2019，12，10： | 8 |
| 3 | Collision Avoidance Strategy Supported by LTE-V-Based Vehicle Automation and Communication Systems for Car Following显示文摘We analyzed and improved a collision avoidance strategy, which was supported by Long Term EvolutionVehicle(LTE-V)-based Vehicle-to-Vehicle(V2 V) communication, for automated vehicles. This work was completed in two steps. In the first step, we analyzed the probability distribution of message transmission time, which was conditional on transmission distance and vehicle density. Our analysis revealed that transmission time exhibited a near-linear increase with distance and density. We also quantified the trade-off between high/low resource reselection probabilities to improve the setting of media access parameters. In the second step, we studied the required safety distance in accordance with the response time, i.e., the transmission time, derived on the basis of a novel concept of Responsibility-Sensitive Safety(RSS). We improved the strategy by considering the uncertainty of response time and its dependence on vehicle distance and density. We performed theoretical analysis and numerical testing to illustrate the effectiveness of the improved robust RSS strategy. Our results enhance the practicability of building driverless highways with special lanes reserved for the exclusive use of LTE-V vehicles. | Jiayang Li Yi Zhang Mengkai Shi Qi Liu Yi Chen | 2020 | Tsinghua Science and Technology2020，25，1： | 5 |
| 4 | The risk factors and threshold level of subchronic inhalation exposure of reclaimed water显示文摘Inhalation of reclaimed water is known to cause lung infammation,and free endotoxins have been shown to be a major risk factor for acute exposure.Subchronic exposure has also been shown to induce infammatory responses with visible tissue damage.However,subchronic risk factors have yet to be identified,and a threshold for the protection of occupational populations during urban reuse is necessary.In this study,potential risk factors in reclaimed water were examined by subchronic exposure with fractionated reclaimed water,and the health risk threshold was tested with a series of diluted reclaimed water.Accordingly,following a 12-week exposure,macromolecules and microorganisms were found to be two major risk factors in reclaimed water that could cause pulmonary infammation,including increased proportion of polymorphonuclear leukocytes in bronchoalveolar fuid,formation of inducible bronchus-associated lymphoid tissue,and elevation of Immunoglobulin A levels.Moreover,infammation persisted after a 4-week recovery period.The calculated threshold of reclaimed water exposure for mice was 31.8 Endotoxin Unit(EU)/(kg·day)under when exposed to 50%additional relative humidity from reclaimed water at 25℃ for 2 hr/day.Meanwhile,the subchronic threshold estimate for humans under the same exposure conditions was found to be 12.2 EU/(kg·day),corresponding to endotoxin levels of 61.7 EU/mL in reclaimed water.The threshold level of endotoxin was lower than that in most non-potable reclaimed water.The findings of this study suggest that occupational exposure of reclaimed water can serve as a potential risk to workers. | Jiayang Kong Yun Lu Yunru Ren Menghao Chen Gang Liu Liangliang Shi | 2024 | Journal of Environmental Sciences2024，，3： | 0 |

| 6 | Chitin oligosaccharides for the food industry:production and applications显示文摘Chitin oligosaccharides(CHOS),high-value-added oligomers linked by N-acetyl-d-glucosamine(GlcNAc,NAG),and a small amount of d-glucosamine(GlcN,GA),have aroused increasing interest due to their excellent biological properties,including antibacterial,anti-inflammatory,and immunoprotective activities,and intestinal regulation.The efficient production and utilization of CHOS with high performance can solve problems from chitin as biowaste.However,the large-scale production of well-defined CHOS has not been fully accomplished due to the limited biotechnology and separation methods,thus impeding the research on their biological functions as well as their accurate applications.In this review,we comprehensively summarize the current preparation methods of CHOS,including the chemical,physical,enzymatic and biosynthetic methods.The advantages and disadvantages of the methods are discussed in terms of efficiency,economy,and environmental effects.Furthermore,the applications of CHOS in the food industry and their contributions to human health based on their excellent bioactivities are expounded.It is hoped that this review will help in providing new insights into the production of CHOS with high precision,and support the application of CHOS in serving the food industry as nutritional supplements or foods for special medical purposes. | Ran Zhang Qiong Zhao Zhenwei Yi Kaihang Zhang Jinqi Shi Liangliang Zhu Yijia Chen Jiayang Jin Liming Zhao | 2023 | Systems Microbiology and Biomanufacturing2023，3，1： | 0 |
