We report the tagging of a brown planthopper (BPH) resistance gene (Bph–1) in rice using RAPD and RFLP markers. The Korean rice variety ‘Gayabyeo’ has dominant duplicate genes including Bph–1 conferring resistance to biotype 1 of BPH. Bulked segregant RAPD analysis was employed for rapid identification of DNA markers linked to resistance genes. For tagging(More)
BcN(Broadband convergence Networks) is being deployed in order to support a variety of network applications such as E-Commerce, DMB(Digital Multimedia Broadcasting), Home Network, VoIP(Voice over IP), and other services. As network bandwidth is growing rapidly and services are converged, the opportunity and severity of network intrusions are growing as(More)
The brown planthopper (BPH) is a major insect pest in rice, and damages these plants by sucking phloem-sap and transmitting viral diseases. Many BPH resistance genes have been identified in indica varieties and wild rice accessions, but none has yet been cloned. In the present study we report fine mapping of the region containing the Bph1 locus, which(More)
The present study was carried out to evaluate genetic divergence among eleven japonica rice cultivars and to assess the relationship between genetic distance and hybrid performance in partial non-reciprocal crosses among them. The 44 F1 hybrids along with the eleven parents were evaluated for five cold tolerance-related traits; discoloration at seedling(More)
In this paper, we propose an intrusion detection system(IDS) architecture which can detect and respond against the generation of abnormal traffic such as malicious code and Internet worms. We model the system, design and implement a simulator using OPNET Modeller, for the performance analysis on the response capacity of alert information in the proposed(More)
BcN(Broadband convergence Network) is being deployed in order to support a variety of network applications, with enhanced capabilities of QoS(Quality of Service) provisioning and security, and IPv6. In a high-speed network environment such as BcN, it is more likely for the network resources to be exposed to various intrusion activities. The propagation(More)
