The GATA factor HANABA TARANU is required to position the proembryo boundary in the early Arabidopsis embryo.


Division of the Arabidopsis zygote defines two fundamentally different developmental domains, the proembryo and suspensor. The resulting boundary separates domain-specific gene expression, and a signal originating from the proembryo instructs the suspensor to generate the root stem cell niche. While root induction is known to require the phytohormone auxin… (More)
