抗草甘膦转基因油菜和野芥菜回交1代子2代-子6代在无除草剂选择压下的适合度转基因作物的抗性基因能否成功渗入野生或近缘杂草取决于携带转基因回交后代的适合度。为深入了解转基因油菜(Brassica napus)向野芥菜(wild ***)基因流动的生态风险,本文研究了在低密度(5株/m^(2))和高密度(10株/m^(2))下,以及单种和混合种植(野芥菜:BC1F2R-BC1F6R=1:1)下抗草甘膦转基因油菜与野芥菜回交1代子2代到子6代(BC1F2R-BC1F6R)的适合度;并分析回交后代的适合度成分、种植密度和种植方式之间的相关性。研究结果表明:在单种低密度下,与野芥菜相比,回交1代子2代(BC1F2R)和子3代(BC1F3R)具有较低的适合度,而回交1代子4代-子6代(BC1F4R-BC1F6R)具有较高的适合度;无论是单种还是混种,高密度下所有回交后代的适合度均低于野芥菜。相关性分析结果显示,种植密度和种植方式对回交后代(BC1F2R-BC1F6R)的适合度成分有显著影响。这些结果表明,转基因从栽培油菜渗入到野芥菜很大程度上取决于回交后代的特定生长环境。

The growing variety of RNA classes, such as mRNAs, lncRNAs, and circRNAs, plays pivotal roles in both developmental processes and various pathophysiological conditions. Nonetheless, our comprehension of RNA functions in live organisms remains limited due to the absence of durable and effective strategies for directly influencing RNA levels. In this study, we combined the CRISPR-RfxCas13d system with spermlike stem cell-mediated semi-cloning techniques, which enabled the suppressed expression of different RNA species. This approach was employed to interfere with the expression of three types of RNA molecules: Sfmbt2 mRNA, Fendrr lncRNA, and circMan1a2(2,3,4,5,6). The results confirmed the critical roles of these RNAs in embryonic development, as their loss led to observable phenotypes, including embryonic lethality, delayed embryonic development, and embryo resorption. In summary, our methodology offers a potent toolkit for silencing specific RNA targets in living organisms without introducing genetic alterations.
