Ribosome recycling factor (RRF), a product of the frr gene, is responsible for the dissociation of ribosomes from messenger RNA after the termination of translation. In order to overexpress frr gene in the toyocamycin (TM) producer Streptomyces diastatochromogenes 1628, we cloned and placed the gene under the control of the constitutive promoter PermE*. The(More)
Streptomyces diastatochromogenes 1628, capable of producing toyocamycin (TM), has exhibited a potential biocontrol effect in inhibiting the development of phytopathogens in the agriculture field. In this study, an efficient transformation system was developed using the intergeneric conjugation. This was achieved by optimization of experimental parameters.(More)
in this paper, we study the power control strategy in wireless ad hoc networks. First the paper analyses the energy saving principles of basic power control and PCM protocol. Then it further explains the implementation in GloMoSim. Finally, simulation results are provided to evaluate the performance of these power control strategies. The simulation results(More)
In this paper, we focus on improving concurrent MAC (CMAC) protocol performance in multi-hop ad hoc networks. Based on the analysis of the collision problems and multi-rate problems of the distributed coordination function (DCF) and CMAC protocol in multi-hop ad hoc networks, we propose a rate adaptive scheme for improving CMAC protocol performance.
