A Study On the Development Strategy For Fujian M Co.， Ltd

改革开放30年来，中国国民经济持续快速发展，带动了作为原材料生产基础工业部门的冶金工业的飞速发展，使之成为世界冶金工业大国。但在近几年的快速发展中，中国冶金工业出现了产能过剩、产业集中度不高、资源短缺、产品结构不合理等一系列问题。在国家产业政策的重点调控和引导下，冶金企业兼并重组风起云涌。作为福建省冶金工业唯一的国有资产运营公司，M公司虽然在福建省占据主导地位，但在全国范围内总体实力仍偏弱。公司存在着对各权属企业的控制力不足、各产业间缺少协同效应、缺少公司层对资源的优化配置机制等问题，制约了公司更大的发展。 本文尝试应用战略管理中最常用的分析工具——波士顿成长份额矩阵和GE矩阵进行公司层战略...Over 30 year’s reform and opening up to the outside world, China’s economy has sustained rapidly development. China has become one of the biggest metallurgical manufactures of basic industrial raw materials that were driven by the growth of economy.

Here we focus on proteomics as a tool for the discovery of differentially expressed proteins closely related to the disease resistance. The leaves of rice cultivar Jiafuzhan (Oryzae sativa L. ) highly resistant to the disease, were infected by"89773-1- 1" strain of the Xooc with strong pathogenicity. Total proteins were extracted from the leaves sampled at two days after inoculation, and separated by two- dimensional electrophoresis. It was found that there were thirty- eight proteins expressed differentially, of which thirty-two were up-regulated, five down-regulated and one was "new". Of the thirty- eight responsive proteins, thirty-three were identified by MALD-I TOF-MS and database searching.Based on the predicted function, we grouped them into four clusters: signal transduction, defensive responses, substance metabolism and protein stabilization, which were involved in many resistant physiological react ions, including signal recognition and transduction, antioxidant react ion, carbonhydrate metabolism, cel-l wall reinforcement and phytoalexin biosythesis. In turn a complex signal transduct ion and metabolic regulative network in the resistant responses to the infection of Xooc was outlined in this work, and the molecular mechanism was revealed by differentially expressed protein/enzyme patterns during Xooc infection. In this study, eight R proteins and three pathogenesis- related(PR) proteins which might relate closely to the disease-resistance were found. This result provides us the basic information to further reveal the resistant mechanism and conduct functional cloning of the resistan-t related genes in rice to BLS.生物农药与化学生物学教育部重点实验室( 福建农林大学) 开放课题基金项目( KF0411
