The stem cell niche in Arabidopsis copes with environmental hazards by enhancing the IRES-dependent translation of WUS mRNA under the control of the AtLa1 protein.
Title: AtLa1 protein initiates IRES-dependent translation of WUSCHEL mRNA and regulates the stem cell homeostasis of Arabidopsis in response to environmental hazards.

Inactivation of AtLa1 (At4g32720) function is lethal and leads to an early developmental arrest of the embryo.
Title: A bona fide La protein is required for embryogenesis in Arabidopsis thaliana.
