About the cover

Inspired by the bronze tree of Sanxingdui, this artwork illustrates the essential role of R-loops in early mammalian embryonic development. Golden helices intertwined among the branches depict how the resolution of R-loops releases paused RNA polymerase II to drive the maternal-to-zygotic transition, whereas their absence results in developmental arrest, highlighting R-loops-mediated transcriptional regulation at the dawn of life.See page 181–196 by Yaoyi Li et al. for details.
