Early plant embryogenesis condenses the fundamental processes underlying plant development
into a short sequence of predictable steps. The main tissues, as well as stem cells for …

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 …

During early plant embryogenesis, precursors for all major tissues and stem cells are formed.
While several components of the regulatory framework are known, how cell fates are …

Maintenance of the stem cell population located at the apical meristems is essential for
repetitive organ initiation during the development of higher plants. Here, we have characterized …

In plants, apical meristems allow continuous growth along the body axis. Within the root
apical meristem, a group of slowly dividing quiescent center cells is thought to limit stem cell …

The plant hormone auxin was initially identified as the bioactive substance that induces
roots in plant tissue culture. In the past decades, mechanisms for auxin action, including its …

Plant growth is directed by the activity of stem cells within meristems. The first meristems are
established during early embryogenesis, and this process involves the specification of both …

Cell-type-specific gene expression is essential to distinguish between the numerous cell types
of multicellular organism. Therefore, cell-type-specific gene expression is tightly regulated …

The stem cells in the shoot apical meristem (SAM) are the origin of all above ground tissues
in plants. In Arabidopsis thaliana, shoot meristem stem cells are maintained by the …

Many developmental processes involve transitions between different cell identities as cells
differentiate or undergo reprogramming. Cell identity specifications are generally associated …
