田间生殖隔离状态下,将野生大豆和栽培大豆种植在抗草甘膦转基因大豆周围,按固定距离收获。每年对一部分实施喷施高剂量草甘膦进行鉴定筛查,另一部分收获留待下年继续鉴定筛查。对每年连续筛查中存活植株提取DNA,进行对目的基因CP4-EPSP... 田间生殖隔离状态下,将野生大豆和栽培大豆种植在抗草甘膦转基因大豆周围,按固定距离收获。每年对一部分实施喷施高剂量草甘膦进行鉴定筛查,另一部分收获留待下年继续鉴定筛查。对每年连续筛查中存活植株提取DNA,进行对目的基因CP4-EPSPS的PCR检测,结果为阴性。初步判断在监测的三年时间内没有发现抗草甘膦转基因大豆通过风媒介使花粉传播,对田间大豆及其近缘种野生大豆产生明显的基因漂移。 展开更多

Great potential exists for new technologies to support flood disaster risk reduction. In addition to existing expert-based data collection and analysis, direct input from communities and citizens across the globe may also be used to monitor, validate, and reduce flood risk. New technologies have already been proven to effectively aid in humanitarian response and recovery. However, while ex-ante technologies are increasingly utilized to collect information on exposure, efforts directed towards assessing and monitoring hazards and vulnerability remain limited. Hazard model validation and social vulnerability assessment deserve particular attention. New technologies offer great potential for engaging people and facilitating the coproduction of knowledge. 展开更多
