科技日报讯 （记者张梦然 实习生周思彤）新一期《自然评论·生物多样性》杂志发表的一项研究显 示，基因编辑技术与传统保护手段结合，将成为拯救濒危物种的关键。 原标题：基因编辑技术将成濒危物种"救星" 不过，该技术存在多重风险：CRISPR等基因编辑技术可能产生脱靶效应，基因多效性在研究较少 的物种中难预判，"选择性清除"可能降低基因组多样性；公众质疑和监管滞后也构成阻碍。 专家强调，基因编辑无法替代传统保护，需在栖息地恢复、反盗猎等措施使种群回升后使用。它虽 非"万能药"，但在气候剧变和栖息地破碎化的当下，为濒危物种存续带来了新希望，成为生物多样性保 护的重要补充工具。 当前生物多样性锐减导致物种遗传多样性持续流失，而遗传多样性是物种适应环境和抵抗疾病的核 心。传统保护措施虽能增加种群数量，却无法恢复已丢失的基因多样性，其自然恢复往往需要数千年。 鉴于此，研究团队表示，博物馆的百年标本可提取已丢失的基因变体，经编辑后重新引入野生种 群。"辅助适应"策略还能从近缘物种引入关键基因，类似农业中番茄植入芥菜抗寒基因、栗树获得小麦 抗病基因的模式。 ...
