| 1 | Identification and fine mapping of quantitative trait loci for the number of vascular bundle in maize stem显示文摘Studies that investigated the genetic basis of source and sink related traits have been widely conducted.However, the vascular system that links source and sink received much less attention. When maize was domesticated from its wild ancestor, teosinte, the external morphology has changed dramatically; however, less is known for the internal anatomy changes. In this study, using a large maize-teosinte experimental population, we performed a high-resolution quantitative trait locus(QTL) mapping for the number of vascular bundle in the uppermost internode of maize stem.The results showed that vascular bundle number is dominated by a large number of small-effect QTLs, in which a total of 16 QTLs that jointly accounts for 52.2% of phenotypic variation were detected, with no single QTL explaining more than 6% of variation. Different from QTLs for typical domestication traits, QTLs for vascular bundle number might not be under directional selection following domestication.Using Near Isogenic Lines(NILs) developed from heterogeneous inbred family(HIF), we further validated the effect of one QTL qVb9-2 on chromosome 9 and fine mapped the QTL to a 1.8-Mb physical region. This study provides important insights for the genetic architecture of vascular bundle number in maize stem and sets basis for cloning of qVb9-2. | Cheng Huang Qiuyue Chen Guanghui Xu Dingyi Xu Jinge Tian Feng Tian | 2016 | Journal of Integrative Plant Biology2016，58，1： | 8 |
| 2 | Genome-wide Analysis of Transcriptional Variability in a Large Maize-Teosinte Population显示文摘基因表示规定在控制植物显型和改编起一个重要作用。这里,我们报导对通过 transcriptome 的基因表示变化的一个全面评价大 maize-teosinte 分析试验性的人口。染色体宽的印射识别了 25 ? 660 表示为 17 的量的特点 loci (eQTL )? 311 基因,捕获表示变化的一个崭新的范围。我们发现本地 eQTL 更经常被印射到邻近的基因,显示表示 piggybacking 的一个模式,它因而创造了共同调整的基因簇。在共同调整的基因簇以内的基因趋于有相关功能和分享的染色质修正。远 eQTL 与他们显著地在特定的功能的范畴充实的目标形成了 125 个重要远 eQTL 热点。由集成信息的不同来源,我们为许多新陈代谢的小径识别了通常认为的 trans- 管理者。我们证明 bHLH 抄写因素 R1 和 hexokinase HEX9 可能分别地为 flavonoid 生合成和 glycolysis 充当关键管理者。而且,我们证明驯服或改进显著地影响了全球基因表示,与选择指向的许多基因。特别兴趣,为生合成可能经历了的 benzoxazinoid 的 Bx 基因协调了在玉米和 teosinte 之间的 cis 规章的分叉,并且当玉米与一个不同草食动物社区传播了进适度的环境,使 Bx12 失去活性的 transposon 插入在强壮的选择下面。 | Xufeng Wang Qiuyue Chen Yaoyao Wu Zachary H.

| 3 | Aggregate modeling and analysis of air conditioning load using coupled Fokker–Planck equations显示文摘Demand response has gained significant attention recently with the increasing penetration of renewable energy sources in power systems. Air conditioning loads are typical thermostatically controlled loads which can play an active role in ancillary services by regulating their aggregated power consumption. The aggregation of air conditioners is essential to the control of air conditioning loads. In this paper, linear state equations are proposed to aggregate air conditioning loads by solving coupled Fokker–Planck equations(CFPEs) using the finite difference method. By analyzing the numerical stability and convergence of the difference scheme, the grid spacings, including temperature step and time step, are properly determined according to the maximal principle. Stationary solutions of the CFPEs are obtained by analytical and numerical methods. Furthermore, a classification method using dimension reduction is proposed to deal with the problem of heterogeneous parameters and interval estimation is applied to describe the stochastic behavior of air conditioning loads. The simulation results verify the effectiveness of the proposed methods. | Dingyi CHENG Wen ZHANG Yutian LIU | 2018 | Journal of Modern Power Systems and Clean Energy2018，6，6： | 4 |

| 5 | Role of thioredoxin-interacting protein in mediating endothelial dysfunction in hypertension显示文摘Excessive oxidative stress is a major causative factor of endothelial dysfunction in hypertension.As an endogenous pro-oxidant,thioredoxin-interacting protein(TXNIP)contributes to oxidative damage in various tissues.The present study aimed to investigate the role of TXNIP in mediating endothelial dysfunction in hypertension.In vivo,an experimental model of acquired hypertension was established with two-kidney,one-clip(2K1C)surgery.The expression of TXNIP in the vascular endothelial cells of multiple vessels was significantly increased in hypertensive rats compared with sham-operated rats.Resveratrol,a TXNIP inhibitor,suppressed vascular oxidative damage and increased the expression and activity of eNOS in the aorta of hypertensive rats.Notably,impaired endothelium-dependent vasodilation was effectively improved by TXNIP inhibition in hypertensive rats.In vitro,we observed that Ang II increased the expression of TXNIP in primary human aortic endothelial cells(HAECs)and that TXNIP knockdown by RNA interference alleviated cellular oxidative stress damage and mitigated the impaired eNOS activation and intracellular nitric oxide(NO)production observed in Ang Il-treated HAECs.However,inhibiting thioredoxin(TRX)with PX-12 completely blunted the protective effect of silencing TXNIP.In addition,TXNIP knockdown facilitated TRX expression and promoted TRX nuclear translocation to further activate AP1 and REF1.TRX overexpressi on exhibited favorable effects on eNOS/NO homeostasis in Ang 11-treated HAECs.Thus,TXNIP contributes to oxidative stress and endothelial dysfunction in hypertension,and these effects are dependent on the antioxidant capacity of TRX,suggesting that targeting TXNIP may be a novel strategy for antihypertensive therapy. | Ruiyu Wang Yongzheng Guo Lingjiao Li Minghao Luo Linqian Peng Dingyi Lv Zhe Cheng Qian Xue Liang Wang Jing Huang | 2022 | Genes & Diseases2022，9，3： | 1 |
| 6 | Prediction of Newhall navel orange internal quality based on digital microscopy显示文摘The traditional technology for internal quality detection of citrus fruit is believed to be destructive,inefficient,and error-prone.To address these issues,a novel method has been developed to evaluate nondestructively the sugar-acid ratio(SAR)of soluble solids by using the oil glands density(OGD).In this study,a total of 584 samples with different widths were collected.The sample data were correlated that the SAR and OGD decreased with time during storage.The relevance with time was significant between SAR and OGD of citrus positively correlated in the calibration group(R2=0.82),which indicated that OGD could be used to predict the internal quality of citrus.It indicated that a new generation of digital microscopy could provide an alternative to predict nondestructively the internal quality of citrus fruit,as well as some theoretical insight for further studies of online quality detection in the future. | Shumin Gao Cong Cao Dingyi Hu Rangwei Xu Yunjiang Cheng Hong Chen Ming Zhu Shanjun Li | 2021 | International Journal of Agricultural and Biological Engineering2021，14，6： | 0 |
