| 3 | Influence of nitrogen and sulfur fertilization on quality of canola(Brassica napus L.) under rainfed conditions显示文摘Field experiments were conducted at Cereal Crops Research Institute, Pirsabak, Nowshera, Pakistan, during winter 2003~2004 and 2004~2005 to evaluate the effect of nitrogen and sulfur levels and methods of nitrogen application on canola (Brassica napus L. cv. Bulbul-98) under rainfed conditions. Four levels of S (0, 10, 20, and 30 kg/ha) and three levels of N (40, 60, and 80 kg/ha) and a control treatment with both nutrients at zero level were included in the experiments. Sulfur levels were applied at sowing while N levels were applied by three methods (100% soil application, 90% soil+10% foliar application, and 80% soil +20% foliar application). The experiments were laid out in randomized complete block (RCB) design having four replications. Oil content increased significantly up to 20 kg S/ha but further increase in S level did not enhance oil content. Glucosinolate content increased from 13.6 to 24.6 μmol/g as S rate was increased from 0 to 30 kg/ha. Protein content increased from 22.4% to 23.2% as S rate was increased from 0 to 20 kg/ha. Oil content responded negatively to the increasing N levels. The highest N level resulted in the highest values for protein (23.5%) and glucosinolate (19.9 μmol/g) contents. Methods of N application had no significant impact on any parameters under study. | AHMAD G. JAN A. ARIF M. JAN M.T.

| 4 | 用于交通标志检测的窗口大小聚类残差SSD模型显示文摘SSD通常被认为适合于求解小目标图像检测问题,但在特征表征和检测效率两方面还存在改进空间.提出一种聚类残差SSD模型,一方面将原始SSD模型中的VGG16基础网络替换为更深的ResNet50残差网络,以改善特征表征能力.另一方面采用K-均值聚类算法取代盲目搜索机制,确定SSD中默认窗口的大小,以改善检测效率.针对德国交通标志检测数据集,模型获得了97.1%mAP和每幅图像0.07 s的检测速度.针对中国交通标志数据集,模型获得89.7%mAP和每幅图像0.08 s的检测速度.与原始SSD模型比较,本文所提模型的检测性能得到改善. | 宋青松 王兴莉 张超 陈禹 宋焕生 KHATTAK Asad Jan | 2019 | 湖南大学学报(自然科学版)2019，46，10： | 4 |
| 5 | TFL1相关基因调控植物花序发育的分子机制显示文摘花序是植物种子的着生组织,对于以种子产量为最终目标的植物来说至关重要,其发育过程非常复杂,受到诸多类基因的调控。TFL1 (TERMINAL FLOWER 1)基因因其突变单株末端着生一朵终止花(terminal flower)而得名,其与AP1和LFY等基因相互作用,可决定植物花序发育的进程。本文围绕TFL1类基因综述植物花序发育调控的最新研究进展,同时展望该类调控基因未来研究方向及应用,为植物花序发育的分子调控机理研究和分子育种提供借鉴。 | 万薇 余坤江 叶波涛 Aimal Nawaz KHATTAK 王天娅 杨仁芹 林树春 田恩堂 | 2020 | 植物生理学报2020，56，3： | 4 |
| 6 | CRISPR/Cas9:A powerful tool for crop genome editing显示文摘The CRISPR/Cas9 technology is evolved from a type II bacterial immune system and represents a new generation of targeted genome editing technology that can be applied to nearly all organisms. Site-specific modification is achieved by a single guide RNA(usually about 20nucleotides) that is complementary to a target gene or locus and is anchored by a protospaceradjacent motif. Cas9 nuclease then cleaves the targeted DNA to generate double-strand breaks(DSBs), which are subsequently repaired by non-homologous end joining(NHEJ) or homology-directed repair(HDR) mechanisms. NHEJ may introduce indels that cause frame shift mutations and hence the disruption of gene functions. When combined with double or multiplex guide RNA design, NHEJ may also introduce targeted chromosome deletions,whereas HDR can be engineered for target gene correction, gene replacement, and gene knock-in. In this review, we briefly survey the history of the CRISPR/Cas9 system invention and its genome-editing mechanism. We also describe the most recent innovation of the CRISPR/Cas9 technology, particularly the broad applications of modified Cas9 variants, and discuss the potential of this system for targeted genome editing and modification for crop improvement. | Gaoyuan Song Meiling Jia Kai Chen Xingchen Kong Bushra Khattak Chuanxiao Xie Aili Li Long Mao | 2016 | The Crop Journal2016，4，2： | 4 |

| 10 | Light quality and temperature effects on antirrhinum growth and development显示文摘An experiment was carried out to examine the effects of light quality on the growth and development of antirrhinum under three different temperatures 19℃, 24℃ and 27℃ in glasshouses. Five different colour filters (i.e. 'Red absorbing', 'Blue absorbing', 'Blue and Red absorbing' and two 'partially Blue absorbing' materials) were tested, with one clear polythene as a control. Plant height, internode length and leaf area were significantly affected by the spectral filters as well as the temperature.Analysis of color filter's effect on presumed photoreceptors to exist indicated that antirrhinum plant height was regulated by the action of a blue acting photoreceptor (BAP) and not the phytochrome. There was no evidence for an effect ofphytochrome or BAP on time to flowering, however, increasing temperature levels effectively decreased the time to flowering. To predict the effects of different spectral qualities and temperature, simple models were created from data on plant height, internode length and time to flowering. These models were then applied to simulate the potential benefits of spectral filters and temperature in manipulation of growth control and flowering in antirrhinum. | KHATTAK Abdul Mateen PEARSON Simon | 2005 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2005，6，2： | 2 |
