The Wnt pathway is central to a host of developmental and disease-related processes. The
remarkable conservation of this intercellular signaling cascade throughout metazoan …

Understanding the mechanism by which patterned gene activity leads to mechanical
deformation of cells and tissues to create complex forms is a major challenge for …

Cellular heterogeneity is a hallmark of multicellular organisms. During shoot regeneration
from undifferentiated callus, only a select few cells, called progenitors, develop into shoot …

The phytohormone auxin influences virtually all aspects of plant growth and development.
Auxin transport across membranes is facilitated by, among other proteins, members of the …

This review highlights recent literature on biomolecular condensates in plant development
and discusses challenges for fully dissecting their functional roles. Plant developmental …

Bryophytes are nonvascular spore-forming plants. Unlike in flowering plants, the
gametophyte (haploid) generation of bryophytes dominates the sporophyte (diploid) …

As scientists, we are at least as excited about the open questions—the things we do not
know—as the discoveries. Here, we asked 15 experts to describe the most compelling open …

Clustering of macromolecules is a fundamental cellular device underlying diverse biological
processes that require high-avidity binding to effectors and substrates. Often, this involves a …

The reiterative organogenesis that drives plant growth relies on the constant production of
new cells, which remain encased by interconnected cell walls. For these reasons, plant …

Cell polarity combined with asymmetric cell divisions (ACDs) generates cellular diversity. In
the Arabidopsis stomatal lineage, a single cortical polarity domain marked by BASL orients …
