MicroRNAs regulate the timing of embryo maturation in Arabidopsis.
The seed is a key evolutionary adaptation of land plants that facilitates dispersal and allows for germination when the environmental conditions are adequate. Mature seeds are dormant and desiccated, with accumulated storage products that are to be used by the seedling after germination. These properties are imposed on the developing embryo by a maturation program, which operates during the lat...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.

Interaction between Two Timing MicroRNAs Controls Trichome Distribution in Arabidopsis
The miR156-targeted squamosa promoter binding protein like (SPL) transcription factors function as an endogenous age cue in regulating plant phase transition and phase-dependent morphogenesis, but the control of SPL output remains poorly understood. In Arabidopsis thaliana the spatial pattern of trichome is a hallmark of phase transition and governed by SPLs. Here, by dissecting the regulatory ...
متن کاملSOMBRERO, BEARSKIN1, and BEARSKIN2 regulate root cap maturation in Arabidopsis.
The root cap has a central role in root growth, determining the growth trajectory and facilitating penetration into the soil. Root cap cells have specialized functions and morphologies, and border cells are released into the rhizosphere by specific cell wall modifications. Here, we demonstrate that the cellular maturation of root cap is redundantly regulated by three genes, SOMBRERO (SMB), BEAR...
