Plants continuously maintain pools of totipotent stem cells in their apical meristems from which
elaborate root and shoot systems are produced. In Arabidopsis thaliana, stem cell fate in …

The classic phytohormones cytokinin and auxin play essential roles in the maintenance of
stem-cell systems embedded in shoot and root meristems, and exhibit complex functional …

Regulatory regions of plant genes tend to be more compact than those of animal genes, but
the complement of transcription factors encoded in plant genomes is as large or larger than …

Flowering of Arabidopsis is regulated by several environmental and endogenous signals.
An important integrator of these inputs is the FLOWERING LOCUS T (FT) gene, which …

The homeotic gene AGAMOUS (AG) has dual roles in specifying organ fate and limiting
stem cell proliferation in Arabidopsis flowers. We show that the floral identity protein LEAFY (LFY)…

There are two main types of root systems in flowering plants, namely taproot systems of
dicots and fibrous root systems found in monocots. Despite this fundamental split, our current …

Floral organ identity is controlled by combinatorial action of homeotic genes expressed in
different territories within the emerging flower. This review discusses recent progress in our …

Flowering of the reference plant Arabidopsis thaliana is controlled by several signaling
pathways, which converge on a small set of genes that function as pathway integrators. We have …

Despite the independent evolution of multicellularity in plants and animals, the basic
organization of their stem cell niches is remarkably similar. Here, we report the genome-wide …

Building expression constructs for transgenesis is one of the fundamental day-to-day tasks
in modern biology. Traditionally it is based on a multitude of type II restriction endonucleases …
