A signal cascade originated from epidermis defines apical-basal patterning of Arabidopsis shoot apical meristems
Abstract
A concentration gradient of HAM transcription factors specifies apical-basal patterning in the Arabidopsis shoot apical meristem. Here, the authors show that epidermal expression of the ATML1 transcription factor defines this concentration gradient via activation of mobile micro RNA.
