Background The phytohormone auxin is critical for plant growth and orchestrates many
developmental processes.• Scope This review considers the complex array of mechanisms …

▪ Abstract Much of plant physiology, growth, and development is controlled by the selective
removal of short-lived regulatory proteins. One important proteolytic pathway involves the …

Abstract MicroRNAs (miRNAs) are∼ 21-nucleotide RNAs, some of which have been shown
to play important gene-regulatory roles during plant development. We developed …

Ubiquitin is well established as a major modifier of signalling in eukaryotes. However, the
extent to which plants rely on ubiquitin for regulating their lifecycle is only recently becoming …

The posttranslational addition of ubiquitin (Ub) helps control the half-life, localization, and
action of many intracellular plant proteins. A primary function is the degradation of …

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 …

Plant shoots elaborate their adult form by selective control over the growth of both their
primary shoot apical meristem and their axillary shoot meristems. We describe recessive …

F-box proteins constitute a large family in eukaryotes and are characterized by a conserved
F-box motif (approximately 40 amino acids). As components of the Skp1p-cullin-F-box …

The nuclear DELLA proteins are highly conserved repressors of hormone gibberellin (GA)
signaling in plants. In Arabidopsis thaliana, GA derepresses its signaling pathway by …

The covalent attachment of ubiquitin is an important determinant for selective protein
degradation by the 26S proteasome in plants and animals. The specificity of ubiquitination is …
