Abstract microRNAs (miRNAs) are an extensive class of newly identified small RNAs, which
regulate gene expression at the post-transcriptional level by mRNA cleavage or translation …

As highlighted by recent genome-wide analyses in diverse organisms and cell types,
subcellular targeting of mRNAs has emerged as a major mechanism for cells to establish …

A key question in developmental biology is how cells exchange positional information for
proper patterning during organ development. In plant roots the radial tissue organization is …

Proper neuronal function and several forms of synaptic plasticity are highly dependent on
precise control of mRNA translation, particularly in dendrites. We find that eIF4AIII, a core …

Drosophila eggs are highly polarised cells that use RNA–protein complexes to regulate
storage and translational control of maternal RNAs. Ribonucleoprotein granules are a class …

Asymmetric cell division generates two cells with different fates and has an important role in
plant development. It produces distinct cell types and new organs, and maintains stem cell …

Plant cells cannot rearrange their positions; therefore, sharp tissue boundaries must be
accurately programmed. Movement of the cell fate regulator SHORT-ROOT from the stele to …

The maize pathogen Ustilago maydis has to undergo various morphological transitions for
the completion of its sexual life cycle. For example, haploid cells respond to pheromone by …

Endoplasmic reticulum (ER) stress triggers the cytoplasmic splicing of XBP1 mRNA by the
transmembrane endoribonuclease IRE1α, resulting in activation of the unfolded protein …

ABSTRACT RNA localization is a regulatory mechanism that is conserved from bacteria to
mammals. Yet, little is known about the mechanism and the logic that govern the distribution …
