Carotenoids are involved in the formation of plant leaf color as well as photosystem photoprotection. This study showed that blue light significantly induced up-regulation of the total carotenoid content in the inner leaves of orange-head Chinese cabbage(OHCC). Furthermore, the transcriptomic analysis revealed that blue light treatment induced upregulation of genes in photosynthesis(BrHY5-2, BrCOP1 and BrDET1) and the methylerythritol 4-phosphate pathways(BrGGPS, BrDXS and BrHDR) upstream of the carotenoid metabolic pathway. Carotenoid metabolomic analysis revealed that the accumulation of several orange and red carotenoids(lycopene, zeaxanthin, β-carotene, lutein, and β-cryptoxanthin) after blue light treatment contributed to the deepening of the leaf coloration, suggesting that short-term blue light treatment could be used to boost nutritional quality. The light signal gene BrHY5-2 participated in the blue light-induced transcriptional regulation of carotenoid biosynthesis in OHCC. Overexpression of BrHY5-2 in Arabidopsis significantly increased the total carotenoid content and the sensitivity to blue light. The above findings revealed new insights about blue-light-induced carotenoid synthesis and accumulation in OHCC lines. They suggested a new engineering approach to increase the nutritional value of vegetables.

为实现高分视频卫星微光条件下对目标进行长周期凝视曝光成像,设计了适应凝视跟踪稳像姿态变化的自适应曝光周期算法.建立卫星对地实时凝视跟踪数学模型,搭建矢量映射的速度匹配曝光成像关系,利用蒙特卡洛方法对卫星三轴姿态角和姿态角速度控制准确度在微光成像曝光时间内引起的像移量进行统计计算,分析了一定姿态控制准确度下满足高分卫星微光成像的曝光周期.最后,利用灵巧验证卫星进行微光成像曝光周期自适应稳像姿态的在轨试验.结果表明,卫星姿态控制准确度分别为0.08°与0.0088°/s和0.04°与0.003°/s时,对应的成像曝光时间分别为18ms和55.2ms,通过对微光成像的目标点进行分析,曝光过程中成像目标点的实际偏差像元量小于1个像元,此偏差对成像质量影响较小,成像影像的信噪比高.

Most cases of acute coronary syndrome （ACS） involve coronary atherosclerosis and plaque rupture, as well as subsequent thrombosis. The initial thrombotic events leading to red thrombus formation are platelet adherence and aggregation. Platelets play a very important role during the establishment and progression of a thrombosis in a coronary artery. Therefore, in recent years guidelines have been developed in an effort to strengthen antiplatelet therapy in ACS, but unfortunately the methods to evaluate platelet activity and the strength of platelet inhibition are lacking.

为了解替代牧草对少花蒺藜草(Cenchrus pauciflorus Benth.)的竞争作用,测定了营养生长中期紫花苜蓿(Medicago sativa L.)根和茎叶水浸提液对少花蒺藜草种子萌发的化感效应。结果表明:紫花苜蓿2种浸提液各浓度对少花蒺藜草种子萌发均具有一定的化感作用,但作用强度和效应存在差异,其中紫花苜蓿茎叶浸提液对少花蒺藜草种子萌发的抑制作用强于根浸提液,以0.1g·mL^(-1)紫花苜蓿茎叶浸提液对种子萌发的抑制效果最强,发芽率仅为51.12%,比对照低了44%;发芽指数为16.37,比对照降低了35.37%;随着发芽时间的延长,同浓度浸提液对少花蒺藜草胚根的抑制作用大于胚芽;浸提液处理过的少花蒺藜草幼苗中丙二醛(MDA)含量均高于对照,且随着浸提液浓度的提高MDA含量增大。初步确定紫花苜蓿可作为替代控制法防控少花蒺藜草的备选植物。
