作为一种渗透调节物质,人们对脯氨酸已经有了很多的研究,然而脯氨酸在生命体生长发育中的作用还知之甚少。为了研究脯氨酸在生长发育中的作用,筛选得到了拟南芥的脯氨酸抗性突变体kao2。突变体在不同浓度脯氨酸培养基上均表现出抗性,但是突变体中脯氨酸的吸收没有显著变化,降解关键基因表达也没有增多。Tail-PCR进行突变基因克隆的结果表明,T-DNA插入位点位于AtKAO2(At2g32440)的第一个外显
随着互联网和计算机的普及,现代社会的数据多以高维信息的形式呈现在大众生活中,人们很难在高维信息中辨别数据的真实性并寻找到所需要的信息。模式识别技术的应用依据是不同物质具有不同特性,通过计算样本间距离的方式归类新样本,该技术已经被广泛的应用在了生物信息学中,本文对此进行了分析。
Photoacoustic tomography is a noninvasive and nonionized biomedical imaging modality but it cannot reveal the inner structure and sideward boundary information of blood vessels in the linear array det
Objective The occurrence of the devastating Wenchuan earthquake not only caused huge economic loss and deaths but also raised a question whether or not it would trigger any destructive earthquakes on
Topography and land use affect soil organic carbon(SOC) storage, stabilization, and turnover, through several biogeochemical processes. This study investigated the aggregate composition and SOC conten
Detecting near-surface soil freeze-thaw cycles in high-altitude cold regions is important for understanding the Earths surface system, but such studies are rare. In this study, we detected the spatial
Soil carbon pools could become a CO_2 source or sink, depending on the directions of land use/cover changes. A slight change of soil carbon will inevitably affect the atmospheric CO_2 concentration an
The grazing incidence focusing X-ray pulsar telescope(iFXPT), as the main payload of the X-ray Pulsar Navigation Test Satellite(XPNAV-1), will have great significance on Chinas space scientific explor
据伊朗媒体7月27日报道,伊当天在新正式启用的伊玛目,霍梅尼国家航天中心成功试射了自主研发的"神鸟"运载火箭。伊媒称,本次发射的"神鸟"火箭可将250千克的卫星送入500千米的近地轨道。而美《福克斯新闻》网站7月28日报道说,两位美官员表示,伊方高调宣布成功的这次发射实际上放了哑炮,起飞后不久就遭遇了"灾难性失败",很可能在进入太空前就已解体。报道说,美战略司令部当天即证实此次发射没有卫星部署入轨
现代工作生活中,人们长期保持一个姿势频繁引发颈椎相关疾病。针对此问题,基于Lab VIEW平台设计了一种通过摄像头交互的颈部保健游戏,以头颈摇动来进行游戏控制,从而使用户在娱乐的同时有效活动颈椎、缓解疲劳、预防颈椎疾病。实验表明,游戏交互灵敏,界面友好,具有趣味性及实用性。
