Knotted1-like homeobox (KNOX) proteins are homeodomain transcription factors that
maintain an important pluripotent cell population called the shoot apical meristem, which …

The shoot apical meristem of angiosperm plants generates leaf, stem and floral structures
throughout the plant's lifetime. To do this, the plant must maintain a population of stem cells …

Cytokinins are hormones that regulate cell division and development. As a result of a lack of
specific mutants and biochemical tools, it has not been possible to study the consequences …

Self perpetuation of the shoot meristem is essential for the repetitive initiation of shoot
structures during plant devel-opment. In Arabidopsis shoot meristem maintenance is …

THE KNOTTED class of plant genes encodes homeodomain proteins1, 2. These genes
have been found in all plant species where they have been sought3–5 and, where …

Meristems are distinctive regions of plants that have capacity for continuous growth. Their
developmental activity generates the majority of plant organs. It is currently unknown how …

The shoot apical meristem (SAM) is a pluripotent group of cells that gives rise to the aerial
parts of higher plants. Class-I KNOTTED1-like homeobox (KNOX) transcription factors …

We have previously described the phenotype of Arabidopsis thaliana plants with mutations
at the CLAVATA1 (CLV1) locus (Clark, SE, Running, MP and Meyerowitz, EM (1993) …

Meristem function in plants requires both the maintenance of stem cells and the specification
of founder cells from which lateral organs arise. Lateral organs are patterned along …

In higher plants, molecular mechanisms regulating shoot apical meristem (SAM) formation
and organ separation are largely unknown. The CUC1 (CU P-SHAPED C OTYLEDON1) …
