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 …

Formative cell divisions are critical for multicellular patterning. In the early plant embryo,
such divisions follow from orienting the division plane. A major unanswered question is how …

The visualization of hormonal signaling input and output is key to understanding how
multicellular development is regulated. The plant signaling molecule auxin triggers many growth …

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 …

Plants have a remarkable potential for sustained (indeterminate) postembryonic growth.
Following their specification in the early embryo, tissue-specific precursor cells first establish …

Leaves originate from stem cells located at the shoot apical meristem. The meristem is
shielded from the environment by older leaves, and leaf initiation is considered to be an …

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 …

Patterning in plants relies on oriented cell divisions and acquisition of specific cell identities.
Plants regularly endure wounds caused by abiotic or biotic environmental stimuli and have …

Plant organs are typically organized into three main tissue layers. The middle ground tissue
layer comprises the majority of the plant body and serves a wide range of functions, …

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 …
