    CAAS ANNUAL REPORT CAAS ANNUAL REPORT 2 0 1 5 Message from the President The year 2015 is a crucial year for deepening reform in China. It has witnessed the successful conclusion of China’s 12th Five-Year Plan and is the scoping year for the upcoming 13th Five-Year Plan. In this important conjunction, Chinese Academy of Agricultural Sciences (CAAS) faithfully adhered to its “顶天立地”（“顶天立地” is a Chinese idiom which means to reach the heavens while keeping the feet on the ground）development strategy, and made significant progress in all-round way. Remarkable gains have been achieved in talent pool, international cooperation and infrastructure construction. Capacity in science and technology innovation, tech- nology transfer, and research infrastructure has kept on improving. Building on the achievements in the past five years, CAAS has come up with its new targets and goals, and envisions greater excellence in the years to come. In 2015, to fulfill the mission of national team for agricultural research, CAAS has rolled out the Agricultural Science and Technology Innovation Program (ASTIP) in a full-fledged way. It is delightful for us to harvest 228 research achievements, 6 of which were awarded by the State Council. The number of papers published in the top internation- al journals such as Nature and Science was doubled over last year. CAAS has played a leading role in the construction of the National Agricultural Science and Technology Innovation Alliance and launched 3 collaborative innovation initiatives, namely the heavy metal pollution control in southern China, black soil protection in northeast China, water saving and grain production ensuring in north China.

    No. 62, June, 2005 The Global Change NewsLetter is the quarterly newsletter of the International Geosphere-Biosphere Programme (IGBP). IGBP is a pro- gramme of global change research, sponsored by the International Council for Science. Compliant with Nordic www.igbp.net Ecolabelling criteria. The so-called Anthropocene is generally considered to have began in the mid-18th century with the start of the 80 year Industrial China and Revolution in Great Britain, which trans- formed a largely agricultural rural population into an urban society supported by industrial factories. This industrialisation spread across Global much of Europe and North America during the 19th century and through other nations such as Russia during the first half of the Change 20th century. This process is now transform- ing China, but on a scale far larger than 200 years ago and at a much faster rate. The scale and pace of industrialisation and urbanisation in China is of course leading to rapid economic and social change, but is also having substantial environmental effects both regionally and globally. Water shortages, desertification, greenhouse gas emissions, particulate air pollution, and elevated sedi- ment and nutrient fluxes to the coastal seas are but some of the side effects of the rapid growth. These and other changes are inter- acting with consequent climate and oceanic effects that are likely to reverberate through- out the Earth System. In this issue of the Global Change Newslet- ter we present a series of articles highlight- ing aspects of current global environmental change research in China. These articles are based on presentations made at a workshop in Beijing, February 2005, on the occasion of the Annual Meeting of the SC-IGBP.

In an effort to identify new factors that relate to how plants respond to ethylene, an Arabidopsis thaliana mutagenesis screen revealed a mutation that is hypersensitive to ethylene. The mutation that gave rise to this aberrant ethylene response phenotype was found to caused by a new pmr6 allele. PMR6 (POWDERY MILDEW RESISTANT 6) encodes a putative pectate lyase that was first identified for pmr6 plants being unable to support powdery mildew growth, presumably by effecting the cell wall composition. The identification of PMR6 as a factor involved in ethylene signaling suggested a novel role and the subsequent characterization of this new pmr6-6 allele utilized known ethylene mutants to characterize the aberrant ethylene response. While pmr6-6 plants do produce additional ethylene, ethylene responses are promoted iv independent of ethylene binding to the receptors in pmr6-6 plants.
