Webb19 juni 2024 · Expression in the pericycle is continuous throughout the top two-thirds of the root, but absent in lateral root primordia and emerging lateral roots (Figure 1J). Negative regulation of ABCB21 expression by cytokinin has been reported in transcriptomic studies (Winter et al., 2007 ) and is consistent with the observed lack of expression in … WebbThis cytoskeleton remodeling intertwines with auxin signaling in the pericycle and endodermis in order for founder cells to acquire a basic polarity required for initiating lateral root development. Our results reveal the conservation of cell remodeling and polarization strategies between the Arabidopsis zygote and lateral root founder cells.
