To see China in a grain of genetically modified rice : a case study on the governance of agricultural biotechnology in ChinaLi, Moxuan January 2010 (has links)
This thesis examines the development and changing practices of governance in China by example of the evolution of policy development in agricultural biotechnology (especially in the case of genetically modified rice). In particular, the process of negotiation between the central government, scientific community, NGOs and the media are brought up to investigate the paradigmatic change in China's development that has been taking place over the last three decades of reform. By drawing on an STS perspective in tandem with social theories, it is argued that the governance of agri-biotech in China could be seen as a process of defining and redefining collective action problems by a widening range of policy actors. This approach is of special pertinence in studying China since its 'techno-nationalist' milieu and complicated and often inconsistent policy process seem to defy the concept of governance. The thesis traces the historical policy development over the governance of agri-biotech in China, and provides a panoramic view on how an increasing number of agents have participated in the process and thereby shaped the collective policy problem. National agri-biotech policy has developed in four distinct phases: an initial phase, marked by technological optimism and lack of regulation; a second, 'the millennium policy‘, distinguished by international pressure from WTO and the Cartagena Protocol; the third phase when scandals of GM rice leakage mobilised widespread public opposition to challenge the current expert policy system; the last stage of intensive policy development occurred since 2008 when global food crises led to the re-evaluation of the collective problem in terms of food security. The China story is not a mere repetition of the European experience in regards to GMO regulation, in that China is still a developing country caught between international forces of trade liberalisation and global biosafety governance, a conflict that is currently complicated in the transatlantic disputes over GMOs. The current policy ambivalence of China is under great pressure to solidify into solutions that can both protect local biodiversity and stand the challenge from international GMO trade. Finally, the opaque nature of China's political culture compromises the efficacy of policy intervention from below, making the policy negotiations an interesting test ground for the possibility of governance from below in the budding prospect of democratisation in China.

Genetics of partial incompatibility and improvement of haploid production in Hordeum vulgare L. x H. bulbosum L. crossesChen, Fu-chiang, Chen, Fuqiang 29 March 1991 (has links)
The production of barley (Hordeum vulgare L.) haploids by crossing with
H. bulbosum is a widely used tool in breeding and genetics. Certain barley
genotypes have low seed set in this interspecific cross, a phenomenon known
as partial incompatibility. Haploid production efficiency and gamete sampling
are important issues with the bulbosum technique, particularly when partially
incompatible genotypes are used. An in vitro floret culture system was
developed that substantially increases haploid production efficiency by
optimizing caryopsis growth, haploid embryo development, and plant
regeneration. The individual and combined effects of three plant growth
regulators (2,4-D, GA₃ and kinetin) on haploid production efficiency and its
determinants were compared in the floret culture system. 2,4-D alone was
superior to GA₃ alone in haploid production efficiency. 2,4-D alone or kinetin +
2,4-D are recommended for the purpose of haploid production in floret culture
using the bulbosum method.
Partial incompatibility between H. vulgare and H. bulbosum was studied
by doubled haploid progeny analysis. Two different loci were hypothesized to
account for the inheritance of partial incompatibility in the crosses of Vada x
Klages, Harrington x Klages, and Vada x Harrington. The partial incompatibility
gene in Harrington was found to be recessive. The dominant nature of the
partial incompatibility gene (Inc) in Vada was confirmed. An association
between the (Inc) gene and a deficiency in a stigma/stylodium-specific high pl
protein was found in the cosegregation analysis of doubled haploid progeny.
The Inc gene may be linked to the gene coding for the stigma/stylodium-specific
protein, or the Inc gene may regulate expression of the protein-encoding
locus. Segregation analysis of Mendelian markers in doubled haploid
progeny showed that there is no evidence that the partial incompatibility status
of the parents has an effect on gamete sampling by the bulbosum technique. / Graduation date: 1991
