Cell cycle regulation is of pivotal importance for plant growth and development. Although
plant cell division shares basic mechanisms with all eukaryotes, plants have evolved novel …

Polycomb-group (PcG) genes encode chromatin proteins involved in stable and heritable
transcriptional silencing. PcG proteins participate in distinct multimeric complexes that …

The ability to use chemical staining to discriminate aborted from non-aborted pollen grains
has well-known practical applications in agriculture. A commonly used technique for …

The development of multicellular organisms relies on the coordinated control of cell
divisions leading to proper patterning and growth,,. The molecular mechanisms underlying …

Stomata are cellular epidermal valves in plants central to gas exchange and biosphere
productivity. The pathways controlling their formation are best understood for Arabidopsis …

Plant growth and development are driven by the continuous generation of new cells.
Whereas much has been learned at a molecular level about the mechanisms that …

This book takes a uniquely integrated approach to the study of floral biology. Flowers are the
beautiful and complex reproductive structures of the angiosperms, one of the most diverse …

In the plant kingdom, events of whole genome duplication or polyploidization are generally
believed to occur via alterations of the sexual reproduction process. Thereby, diploid pollen …

The maintenance of stem cells in defined locations is crucial for all multicellular organisms.
Although intrinsic factors and signals for stem cell fate have been identified in several …

Target of rapamycin (TOR) is a protein kinase that coordinates eukaryotic metabolism. In
mammals, TOR specifically promotes translation of ribosomal protein (RP) mRNAs when …
