In doing so, I also send my best wishes for thesuccess of this important journal in spreading the knowledge of andrology throughout the most populous continent in theworld. This new journal appears at a very timely moment, at the turn of the millennium and at a time when andrology isreceiving the recognition amongst medical specialities that it deserves. In conclusion, I would like to call on all Asianandrologists to support their journal and to work to improve the reproductive health of men.展开更多

Although homology-directed repair(HDR)is a feasible approach to achieve precise gene replacement and base substitution in some plant species, the dominance of the non-homologous end joining pathway and low efficiency of HDR in plant cells have limited its application. Base editing has emerged as an alternative tool to HDR-mediated replacement, facilitating precise editing of plant genome by converting one single base to another in a programmable manner without a doublestranded break and a donor repair template. In this review, we summarize the latest developments in base-editing technologies as well as their underlying mechanisms. We review current applications of these technologies in plant species. Finally, we address the challenges and future perspectives of this emerging technology in plants.展开更多
