Comparative physical mapping of rice BAC clones linked to resistance genes Glh,Bph-3 and xa-5 in Oryza sativa L. and O. granulata Nees et Arn. ex Watt.

Oryza granulata Nees et Arn. ex Watt. is one of the three wild relatives of rice,which are the most valuable for study and utilization in China.In this study,the homology and physical locations of three rice resistance genes,Glh,Bph-3 and xa-5 are comparatively analyzed between O.sativa and O. granulata by Southern blotting and fluorescence in situ hybridization (FISH).The results of Southern blotting indicate that there exist homologous sequences of the tested RFLP markers in O. granulata.By using three bacterial artificial chromosome (BAC) clones scanned by the tested RFLP as probes, FISH signals are detected on both mitotic and pachytene chromosomes in O.sativa and O.granulata.Dual-color FISH demonstrates that two of the three BAC clones (14E16 and 38J9) are located on the short arm of the same chromosome pair in O. granulata. Additionally, colinearity is shown for the two clones between O.sativa and O.granulata. Another BAC clone 44B4 is located on the end of the short arm of other chromosome pair in these two species.Although the phylogenetic relationship between O.sativa and O.granulata is the most distinct in Oryza and these two species have evidently different biological features and ecological habits, the relative lengths and arm ratios of the detected chromosomes and the relative positions of the tested clone signals on chromosomes in O. granulata are quite similar to those in O. sativa.

区域创新网络知识溢出效应研究

区域创新网络内正式或非正式互动学习的存在 ,使网络内部各个成员的研究开发活动产生知识溢出效应。通过建立知识溢出效应模型 ,认为区域创新网络中知识溢出呈现螺旋上升态势 ;知识溢出带来区域集聚经济、规模经济形成的同时也造成区域产品雷同化和网络内部企业的竞争加剧。解决问题的有效途径是将知识溢出效应的外部性内在化 ,通过某种方式将外部收益或成本内含于某种经济关系中。内在化的过程就是使个别厂商的成本与社会成本相等的过程 ,也是通过外力对企业生产函数调整的过程。具体实施方式主要包括政府干预、产权制度安排和道德约束
