Beating the bounds: how does ‘open source’ become a seed commons?

In response to ongoing plant genetic enclosures, the Open Source Seed Initiative (OSSI) is creating a ‘protected commons’ for seed. It is a project, I argue, that reflects characteristics of a growing transnational commoning movement. From the Zapatistas to seed wars, such movements draw attention to commons not simply as a resource, but as a dynamic and evolving social activity: commoning. In the US, OSSI includes 38 plant breeders, 48 seed companies and 377 crop varieties. Yet challenges remain for OSSI to gain wider legitimacy for ‘freed seed’, to build trust in a moral pledge, and to establish fair guidelines for which people and which seed can participate in making the commons. Using the metaphor of ‘beating the bounds’ – a feudal practice of contesting enclosures – I ask how OSSI defends the commons in intersecting arenas. The first way is legal, as OSSI negotiates a move from contract law toward moral economy law. Next is epistemic, as an informal breeder network revitalizes farmer knowledge, while proving more structurally able and culturally equipped to lead commoning efforts. Finally, I reflect on the nature of boundary beating itself, aided by Global South movements. Seed sovereignty perspectives suggest room for a pluriverse of commons to grow.     

Public Perceptions of Benefits from and Worries over Plant‐Made Industrial Products and Plant‐Made Pharmaceuticals: The Influence of Institutional Trust

Although agricultural biotechnology has been a seminal reference point in risk perception studies, public awareness of their exposure to risk deriving from this new technology has been minimal at best. However, recent events indicate there may be growing public concern as new variations of this technology appear. Understanding what drives perceptions of benefits from the third generation of the agricultural biotechnology and what determines public worries are keys for the future of this technology. To this end, this study analyzes survey data from the midsouth region of the United States to construct four separate regression models of perceived benefits from and worries over plant‐made industrial products and plant‐made pharmaceuticals. Findings suggest that while prior experience with and knowledge about agricultural biotechnology has an impact on perceptions of benefits and worries, trust in farmers plays a highly important role in determining perceptions.

基于ITS2条形码序列对新型“香料”毒品植物成分的研究

目的应用DNA条形码片段ITS2对新型毒品样品中的植物成分进行分析。方法提取可疑毒品样本"spike99","K2","7号"中的植物基因组DNA,用ITS2通用引物进行扩增,对扩增产物进行测序,对序列校对拼接,应用BLAST方法在NCBI数据库中比对。结果 "spike 99"、"7号"各得到1条ITS2基因序列,"K2"得到2条ITS2基因序列,分别与紫花苜蓿、大麻、啤酒花、黄蜀葵的ITS2基因序列的同源性为100%。结论应用条形码技术可以成功分析新型毒品中的植物种属,为案件中植物样本的种属鉴定提供方法。     

三妙丸方诸药基原考

目的 对《医学正传》三妙丸中诸药的基原植物进行考证,为临床正确选药提供依据。方法 查阅古代本草、方书和2010年版《中华人民共和国药典》（一部）及相关研究文献,梳理三妙丸的使用沿革,研究三妙丸及其加味方的使用历史。结果 三妙丸中牛膝原载为川牛膝,其原植物或为川牛膝Cyathula officinalis Kuan。然清代、民国时期多用怀牛膝组方,其原植物为怀牛膝Achyranthes bidentata Bl.。现今临床川牛膝、怀牛膝皆用,而《中华人民共和国药典》规定三妙丸中用怀牛膝。方中苍术原载为苍术,原植物为茅苍术Atractylodes lancea (Thunb.) DC.,现今多使用其栽培品以及北苍术A. chinensis (DC.) Koidz.。方中黄柏即为川黄柏Phellodendron chinense Schneid.,供应不足时亦可用关黄柏P. amurense Rupr.代替。结论 三妙丸方中3味药的基原植物分别为川牛膝、茅苍术和川黄柏。
