Through monopoly status, foreign suppliers can raise seed prices and drive hundreds of millions of Chinese farmers bankrupt and trigger social unrest, the China Business News (CBN) reported Monday, citing Jiang Gaoming, an ecologist at the Institute of Botany under the Chinese Academy of Sciences. China should draw lessons from the impact of foreign GM soybeans, and must control foreign GM seeds entering the Chinese market, Jiang was quoted as saying by the CBN. China went from a major soybean producer to the largest soybean importer in 2002 when it abolished an import quota and tariff on soybeans. China imported a total of 42.6 million tons of soybeans in 2009, up 14 percent over 2008. Chinese customs data shows 97.4 percent of the soybeans were imported from the US, Brazil and Argentina. Four international grain dealers, ADM, Bunge, Cargill and Louis Dreyfus, had acquired 64 out of 90 China cooking oil processors using soybeans by 2008. So far there is no scientific proof of the potential harm of genetically modified food. But genetic modification can't necessarily contribute to an increase in crop output, said Fang Lifeng, director of Greenpeace's agriculture and food program. Some GM cotton shows minor problems at the seventh year of planting, said Du Jianjun, manager of a seeding company based in Xuzhou, Jiangsu Province. Fang said that genetically modified cotton can resist bollworms but is vulnerable to other kind of pests, which leads to increased costs for other pesticides and pollution after years of planting, based on Greenpeace's field visit to cotton farmers in Yancheng, Jiangsu Province. Unlike the US and Argentina where large farm areas are suited for the use of machinery, much of China's farmland is scattered, and herbicide-resistant GM crops don't save costs for Chinese farmers. Genetically modified seeds are normally priced two to four times more than non-genetically modified seeds, eroding farmers' income, Fang said. So far only two GM crops, cotton and papaya, are allowed to be planted in China, Fang said. He added that the Ministry of Agriculture last November granted safety certificates to two types of GM rice and one type of GM corn without giving information on food and environmental safety, or the timetable for final commercialization of the GM crops. That has sparked concern as rice is the major staple food in China and the country will be the first to have a major food genetically modified, Fang said. Genetically modified technology in grain might play an important role in China's grain output, as China is short of arable land, said Weng Ming, a researcher at the Institute of Rural Development of the Chinese Academy of Social Sciences. The Chinese government encourages independently developed genetically modified agricultural products, the central government wrote in an agricultural policy document released in January. The two types of GM rice given safety certification involve 10-12 patents of foreign seed companies such as Monsanto, which has more than 80 percent of the market share of genetically modified seeds worldwide, Fang said. He said these patents may remain free during scientific research, but once commercialized, the foreign patent owners might manipulate the price of seeds through technology transfers to seed wholesalers, causing rice price hikes and social impacts. If it relies on imports, China might lose control of its own food supply, Fang noted. By Wang Xinyuan Source: Global Times
终于能有个科学网的博客，很是happy！ 在键盘上敲敲打打的时候也是一个理顺思路的过程，个人觉得，比玩游戏，看电影要有意思些。写下的，是自己的思想痕迹； 看见的，只是在别人的生活或杰作里被动表达而已。 今天似乎还有些小小的收获，知道了一个叫Futuragene 的公司。 以前只知道Monsanto , pioneer, syngenta，bayercrop science，dowagro在植物分子、育种及农化这块很厉害，经常在查询专利数据库的时候，能看到他们申请的很多专利文献。 突然在网上看到说2009年12月3号，拜耳作物科学公司与FuturaGene上市公司在伦敦就棉花抗旱技术签署许可协议，该协议准许拜耳作物科学公司有权利用FuturaGene公司的棉花抗旱技术。 一下子不知道这个从未听过的Futuragene是什么来头，也不知道他们的抗旱技术原来有那么厉害，甚至有报道说Futuragene' s drought-tolerance gene gets Chinese patenton Dec16 ,2009。于是为了找这个他们的这个中国专利Method for increasing stress tolerant in plants , 花费了我一上午的时间，在国家知识产权局，美专局，欧专局，用各种关键词，公司名称，等等，都试了一遍，还是没有找到。 哎，看来我的专利检索技术依旧得进一步加强。 虽然有些郁闷，没有得到想要的结果，但发现了自己依旧有许多要学的东西，对于个人发展来说还是不错的。继续加油吧。 昨儿第N次看了'Forest gump, 记住了其中一句话： i don't know if we all have a destiny , or if we are just all floating accidentally- like in a bree. 想想，原来阿甘也是有迷茫的。
看到这个消息，不知道是该高兴还是忧虑。 这几年祖国的科学发展简直是江山一片红，SCI 文章数量大幅上涨，现在连化学专利数量都全球第一了。看来，领导们的创新中国宏伟蓝图差不多提前实现了。真心希望那些专利中间垃圾专利的比例很低，否则，光申请费用都是很大的一笔开支。除非那个数字可以算进GDP，否则是没有其它益处的 sources: http://pubs.acs.org/cen/science/88/8802sci1.html http://www.cas.org/newsevents/releases/chinesepatents112309.html China Leads All Nations in Publication of Chemical Patents According to CAS, the World's Most Authoritative Publisher of Chemical Information Columbus, Ohio (November 23, 2009) - Chemical Abstracts Service (CAS), the global expert on chemical information, reports that China's patent office is now the world's leading producer of patent invention applications in chemistry. China trailed Japan's patent office, the World Intellectual Property Organization (WIPO), and the United States Patent and Trademark Office (USPTO) for more than a decade, but passed the USPTO in 2005, WIPO in 2006, and exceeded Japan for the first time on a monthly basis in 2008. In 2009, China will record an entire year as the number one producer of chemical patents, and CAS projects that trend to continue. Chemistry is widely recognized as 'the central science,' according to Dr. Matthew Toussant, senior vice president of editorial operations at CAS. Chemical patents are a critical component to many industrial processes and scientific realms, including medicine and natural products, said Toussant. In fact, on average, 35 percent of new patent invention applications involve chemical substances. CAS has been recording the phenomenal growth of patent documents in the last decade, with the number of chemistry-related patent publications by the USPTO and WIPO growing by more than 500 percent, said Christine McCue, vice president of marketing at CAS. Meanwhile, Chinese invention applications increased by nearly 1,400 percent, with much of that growth taking place in the pharmaceutical sector. More than half of the Chinese patent applications during this period were from inventors within China, which surely indicates that Chinese scientists now also recognize the importance of monetizing research discoveries. Hundreds of CAS scientists, aided by state-of-the-art technology, identify and record the chemistry obscured in patents that standard search engines cannot locate. Proprietary technology systems developed by CAS enable scientists working around the world to analyze patents from 60 global patent authorities. Patent documents meeting CAS selection criteria from nine major patent offices are available in CAS databases within two days of the patents' issuance, and are fully indexed in less than 27 days. CAS scientists add value to the data they collect, entering chemical names, a unique CAS Registry Number, literature references, property data, commercial availability, preparation details, spectra, and regulatory information from international sources into CAS databases.
