In this study, two rice BAC clones closely linked to rice gall midge resistance, Gm-2 and Gm-6, were in situ hybridized to Oryza officinalis chromosomes. They were located on the long arm of chromosome 4 with FL 72.33% and 77. 10% respectively and their FL was consistent with the selective marker of rice, RG214 and RZ569. The frequency of signal detection was 61.2% and 59.5% respectively. Our study was based on comparative RFLP map of wild rice, O. officinalis, and cultivated rice, O.sativa.展开更多

Research on atmospheric electricity has been actively conducted since the 1980 s in China. Lightning physics and its effects, as important branches of atmospheric electricity, have received more attention because of their significance both in scientific research and lightning protection applications. This paper reviews atmospheric electricity research based primarily on ground-based field experiments at different regions in China in the last decade. The results described in this review include physics and effects of lightning, rocket-triggered lightning and its physical processes of discharge, thunderstorm electricity on the Tibetan Plateau and its surrounding areas, lightning activity associated with severe convective storms, the effect and response of lightning to climate change, numerical simulation of thunderstorm electrification and lightning discharge, lightning detection and location techniques, and transient luminous events above thunderstorms.展开更多
