The F-box is a protein motif of approximately 50 amino acids that functions as a site of
protein-protein interaction. F-box proteins were first characterized as components of SCF …

▪ Abstract Protein degradation is deployed to modulate the steady-state abundance of
proteins and to switch cellular regulatory circuits from one state to another by abrupt …

The importance of the ubiquitin-proteasome pathway to cellular regulation in eukaryotes has
become increasingly apparent during the last several years. This fact was formally …

Summary Jasmonates (JAs) regulate Arabidopsis thaliana wound and defence responses,
pollen development, and stress‐related growth inhibition. Significantly, each of these …

The initial steps of flower development involve two classes of consecutively acting regulatory
genes. Meristem-identity genes, which act early to control the initiation of flowers, are …

Organ asymmetry is thought to have evolved many times independently in plants. In
Antirrhinum, asymmetry of the flower and its component organs requires cyc and dich gene …

The ubiquitin proteasome system is a key regulator of many biological processes in all
eukaryotes. This mechanism employs several types of enzymes, the most important of which …

In Antirrhinum, floral meristems are established by meristem identity genes. Floral meristems
give rise to floral organs in whorls, with their identity established by combinatorial activities …

The SCF complex is a widely studied multi-subunit ring E3 ubiquitin ligase that tags targeted
proteins with ubiquitin for protein degradation by the ubiquitin 26S-proteasome system …

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 …
