Coordination of cell division and pattern formation is central to tissue and organ development,
particularly in plants where walls prevent cell migration. Auxin and cytokinin are both …

Positional information is a central concept in developmental biology. In developing organs,
positional information can be idealized as a local coordinate system that arises from …

The Arabidopsis root offers good opportunities to investigate how regulated cellular growth
shapes different tissues and organs, a key question in developmental biology. Along the …

Multicellular development requires coordinated cell polarization relative to body axes, and
translation to oriented cell division 1 , 2 – 3 . In plants, it is unknown how cell polarities are …

Plants have the ability to continously generate new organs by maintaining populations of stem
cells throught their lives. The shoot apical meristem (SAM) provides a stable environment …

The root vascular tissues provide an excellent system for studying organ patterning, as the
specification of these tissues signals a transition from radial symmetry to bisymmetric patterns. …

Morphogenesis is the creation of form, a complex process requiring the integration of
genetics, mechanics, and geometry. Patterning processes driven by molecular regulatory and …

Positional information is a central concept in developmental biology. In developing organs,
positional information can be idealized as a local coordinate system that arises from …

How traits evolve to produce novelty or stasis is an open question in biology. We investigate
this question in Cardamine hirsuta, a relative of Arabidopsis thaliana that employs explosive …

Exploding seed pods of the common weed Cardamine hirsuta have the remarkable ability
to launch seeds far from the plant. The energy for this explosion comes from tension that …
