"在一定范围内，水稻接收的光照时间越短，抽穗越快，水稻越早熟。"论文的共同通讯作者、南京 农业大学教授周时荣介绍，水稻的抽穗受光信号与内源生物钟系统的复杂调控。然而，关于光信号整合 至水稻生物钟网络的机制仍迷雾重重。 研究团队克隆了一个在长日照条件下特异性调控水稻抽穗的基因ELD1。该基因功能完全缺失会导 致水稻胚胎死亡，但当特定氨基酸发生突变时，不仅能够显著促进水稻抽穗，而且不会出现明显的农艺 性状缺陷。 原标题：我科学家发现调控水稻抽穗期关键基因 科技日报讯 （记者金凤）挖掘水稻新的抽穗期基因并解析其作用机制，对培育高产、优质、广适 的水稻品种具有重要意义。记者7月21日获悉，中国工程院院士万建民团队通过克隆一个在长日照条件 下特异性调控水稻抽穗的基因，发现该基因可以调控水稻生物钟核心基因OsCCA1的mRNA剪接，影响 水稻抽穗期。相关研究成果日前发表在国际学术期刊《自然·通讯》上。 周时荣介绍，上述研究不仅揭示了光信号调控水稻抽穗期的全新机制，还在分子育种上取得了突 破。研究团队利用碱基编辑技术，对ELD1关键氨基酸进行定点突变，为宁粳7号、宁粳4号等优良品种 培育出早抽穗新种质开辟了新路径。 "本研 ...

原标题：渐进式修复为河流"疗伤" 人类活动正在以前所未有的速度重塑着河流生态。 刘俊国在2024年度中国生态环境十大科技进展发布会上说："全球近50%的河流因水坝、引水工程 等导致连通性减弱，超过一半的河流生物多样性已发生显著变化。"从非洲尼罗河到欧洲莱茵河，从中 国长江到北美密西西比河，这一现象普遍存在。 应对这场危机，现有理论在用于我国河流修复时面临双重困境：国外主流"自修复"理论对于已高度 退化的河流来说，如同"让重症患者自愈"；而国内曾过度依赖的工程手段虽能短期改善水质，却忽略了 生态系统的整体性。"有些河流看起来'干净了'，但水生生物多样性并未恢复——因为水流的自然节律 被破坏，水生生物的产卵场、栖息地消失了。"刘俊国说。 气候变化也在改变河流生态。刘俊国形象比喻道："就像人有昼夜节律，河流也有'四季脉搏'。"河 川径流季节性变化是生态系统的核心"生命线"，但气候变化正悄然改变这一规律。"此前，学界一直没 彻底弄明白，气候变暖到底让河流的季节水量改变了多少？是怎么改变的？"他坦言，"这让我们在修复 河流时像盲人摸象，找不到精准靶点。"在该领域的认知空白，也让现有修复理论受到挑战。 从分析节律到理论创 ...

◎科技日报记者 张梦然 你家的狗子会盯着电视目不转睛吗？它们是被剧情吸引，还是单纯把屏幕当镜子？发表在《科学报告》 的一项研究揭示：狗狗的观影习惯，竟然和它们的性格息息相关。 美国奥本大学研究团队脑洞大开，决定研究狗狗与电视的奇妙互动。他们招募了650名"铲屎官"，最终 给453只"汪星人"成功建立了"观影档案"。他们发现了一个惊人的规律：那些活泼好动的"兴奋型"狗 狗，看到屏幕里滚动的网球、飞舞的蝴蝶时，会像追捕猎物一样跃跃欲试，甚至想把爪子伸进屏幕里。 而胆小的"敏感型"狗狗，听到电视里传来门铃、汽车喇叭声，则会瑟瑟发抖，躲到沙发底下当"鸵鸟"。 更神奇的是，45%的狗狗堪称"声音控"，只要电视里传来狗狗的叫声，就会立刻竖起耳朵，仿佛在和远 方的同胞隔空对话。这些发现让科学家们直呼："狗狗的内心戏比电视剧还精彩。" 这项研究就像给狗狗打开了"性格鉴定仪"，不仅让我们更懂狗狗的内心世界，还给养狗人士提供了实用 建议：想健康追剧？记得每天控制狗狗观看时间在15分钟以内，优选自然风光和动物互动节目，避开恐 怖片，如果它出现过度反应最好立即换台。 科学家也提醒，由于研究对象都是经常接触电视的宠物狗，研究结果可能无 ...
