Polar transport of auxin is important for plant growth and development.The directional auxin flow depends on the polar subcellular localization of PIN auxin efflux regulators in plant.Overexpression of the PINOID protein kinase induces a basal-topical shift in PIN localization, resulting in the loss of auxin gradients and strong defects in embryo and seedling roots.In this study, the phosphorylated peptides in seedlings of 35S: :PID and wide type Arabidopsis were analyzed using solid metal affinity chromatography and dimethyl tag-based quantification mass spectrometry approaches.

持留菌是特定环境下细菌相关功能基因表达或关闭后呈现的一种表型异化状态,可耐受致死浓度抗生素,又不同于抗药性突变体,与细菌持续性感染密切相关.持留菌的形成机制是目前研究热点,而金葡菌持留相关基因及其机制的研究尚在起步阶段.

人类文明是对人类生存水平的描述,包括物质文明、精神文明与环境文明.自人类出现以来,已经经历了原始文明、农业文明和工业文明三个发展阶段.以往的人类文明过度地强调了物质文明和精神文明的建设,对于环境文明的认识不够,没有充分考虑到物质文明、精神文明与环境文明的相互作用.生态文明是对已有文明的继承与有序发展,是人类对传统的生活方式、生产方式和思维方式的进一步升华.生态文明是建立在人类与自然和谐相处基础上的
土壤养分特征和酶活性对土壤质量变化十分敏感,是指示土壤肥力的重要指标,根际是植物与土壤环境最紧密的接触面,对环境极为敏感,具有特殊的物理、化学及生物学特性.以江西永丰县官山林场4种不同施肥处理(45%矿渣肥、39%矿渣肥、毛竹专用肥和对照)的毛竹林为研究对象,研究了不同施肥处理对不同年龄毛竹根土壤养分性质和酶活性的影响.
毛竹(Phyllostachys edulis)通过克隆生长不断向邻近阔叶林扩张,并在竹林与阔叶林间形成一个特殊的竹林-阔叶林界面(简称竹阔界面),界面两侧的养分特征强烈影响着毛竹扩张格局与过程.本文采用Hedley分级方法对界面两侧毛竹林与阔叶林土壤磷素进行分级分析.

为了说明不同植被对石漠化地区土壤微生物功能多样性的影响,以便为石漠化治理先锋树种的选择提供理论依据,利用BIOLOG技术和主成分分析等方法,对桂西北石漠化地区青檀(Pteroceltis tatarinowii)、青冈(Cyclobalanopsis glauca)、阴香(Cinnamomum bumanii)、任豆(Zenia insignis)、吊丝竹(Dendrocalamus minor)
新疆古尔班通古特沙漠南缘发育这良好的生物土壤结皮,在典型沙垄垄间低地分布这大量的蛇麻黄灌丛,其灌丛下发育着以齿肋赤藓为优势的苔藓结皮,在荒漠生态系统地表稳定性和植被演替中发挥着重要的生态功能.本文研究了新疆古尔班通古特沙漠苔藓结皮中的种类组成,并利用藻类的胞外多糖和苔藓的提取液进一步研究了它们的种间关系.
