| 1 | The impacts of stress on the chemical structure of coals:a mini-review based on the recent development of mechanochemistry显示文摘The chemical structure evolution of coal,which is important for understanding coalification and the accompanying volatile and possible oil generation,is generally thought to be influenced by temperature,time and confining pressure.Though evidence concerning the impacts of stress on the chemical structure has accumulated for many years and some hypotheses have been proposed,the mechanism remains controversial.Recent years have seen a breakthrough in mechanochemistry,which proves that stress can act on the molecule directly to initiate or accelerate reactions by deforming the chemical bonds.The progress in mechanochemistry gives researchers incentive to consider how stress works on the chemical structure of coals.Preliminary quantum chemical calculations have been performed on the macromolecule of anthracite to explain the mechanism of gas generation during the deformation experiments at low temperatures.This paper briefly reviews the evidence regarding the impacts of stress on the chemical structure of coals and introduces the recent achievements in the mechanism research.To further investigate this problem,more work should be undertaken by researchers from both geology and quantum chemistry fields. | Quanlin Hou Yuzhen Han Jin Wang Yijing Dong Jienan Pan | 2017 | Science Bulletin2017，62，13： | 5 |
| 2 | Genomic prediction of yield performance among single-cross maize hybrids using a partial diallel cross design显示文摘Genomic prediction(GP)in plant breeding has the potential to predict and identify the best-performing hybrids based on the genotypes of their parental lines.In a GP experiment,34 elite inbred lines were selected to make 285 single-cross hybrids in a partial-diallel cross design.These lines represented a mini-core collection of Chinese maize germplasm and comprised 18 inbred lines from the Stiff Stalk heterotic group and 16 inbred lines from the Non-Stiff Stalk heterotic group.The parents were genotyped by sequencing and the 285 hybrids were phenotyped for nine yield and yield-related traits at two locations in the summer sowing area(SUS)and three locations in the spring sowing area(SPS)in the main maizeproducing regions of China.Multiple GP models were employed to assess the accuracy of trait prediction in the hybrids.By ten-fold cross-validation,the prediction accuracies of yield performance of the hybrids estimated by the genomic best linear unbiased prediction(GBLUP)model in SUS and SPS were 0.51 and 0.46,respectively.The prediction accuracies of the remaining yield-related traits estimated with GBLUP ranged from 0.49 to 0.86 and from 0.53 to 0.89 in SUS and SPS,respectively.When additive,dominance,epistasis effects,genotype-by-environment interaction,and multi-trait effects were incorporated into the prediction model,the prediction accuracy of hybrid yield performance was improved.The ratio of training to testing population and size of training population optimal for yield prediction were determined.Multiple prediction models can improve prediction accuracy in hybrid breeding. | Ping Luo Houwen Wang Zhiyong Ni Ruisi Yang Fei Wang Hongjun Yong Lin Zhang Zhiqiang Zhou Wei Song Mingshun Li Jie Yang Jianfeng Weng Zhaodong Meng Degui Zhang Jienan Han Yong Chen Runze Zhang Liwei Wang Meng Zhao Wenwei Gao Xiaoyu Chen Wenjie Li Zhuanfang Hao Junjie Fu Xuecai Zhang Xinhai Li | 2023 | The Crop Journal2023，11，6： | 0 |
| 3 | A differentially methylated region of the ZmCCT10 promoter affects flowering time in hybrid maize显示文摘Flowering time(FT) is a key maize domestication trait, variation in which allows maize to grow in a wide range of latitudes. Although previous studies have investigated the genetic control of FT-related traits per se, few studies of FT hybrid performance have been published. We characterized the genomic architecture associated with hybrid performance for FT in a hybrid panel by testcrossing Chang 7–2 with 328Ye478 × Qi319 recombinant inbred lines(RILs). We identified 11 quantitative trait loci(QTL) for hybrid performance in FT-related traits, including a major QTL qFH10 that controls hybrid performance and heterosis in a summer maize-growing region. However, this locus acts in regulating FT traits per se only in a spring maize-growing region. We validated ZmCCT10 as a candidate gene for qFH10 and found that differences between hybrids and their parental lines in DNA methylation in the differentially methylated region(DMR, –700 to –1520) of the ZmCCT10 promoter affected gene expression pattern and thereby FT in the summer maize-growing region. | Zhiqiang Zhou Xin Lu Chaoshu Zhang Mingshun Li Zhuanfang Hao Degui Zhang Hongjun Yong Jienan Han Xinhai Li Jianfeng Weng | 2023 | The Crop Journal2023，11，5： | 0 |
