Plants, like other eukaryotes, rely on proteolysis to control the abundance of key regulatory
proteins and enzymes. Strikingly, genome-wide studies have revealed that the ubiquitin-26S …

RING zinc finger proteins have a conserved RING domain, mainly function as E3 ubiquitin
ligases, and play important roles in plant growth, development, and the responses to abiotic …

Owing to a sessile lifestyle in nature, plants are routinely faced with diverse hostile
environments such as various abiotic and biotic stresses, which lead to accumulation of free …

In eukaryotic cell nuclei, chromatin states dictated by different combinations of post-
translational modifications of histones, such as acetylation, methylation and …

In all eukaryotes chromatin physically restricts the accessibility of the genome to regulatory
proteins such as transcription factors. Plant model systems have been instrumental in …

Seed dormancy is defined as the failure of a viable seed to germinate under favorable
conditions. Besides playing an adaptive role in nature by optimizing germination to the most …

As we near a complete understanding of plant transcriptomes and their corresponding
proteomes, a remaining frontier in plant biology will be the in-depth definition of the …

This work examines the role of the Arabidopsis thaliana RING E3 ligase, HISTONE
MONOUBIQUITINATION1 (HUB1) in disease resistance. Loss-of-function alleles of HUB1 …

Ubiquitination is one of many known histone modifications that regulate gene expression.
Here, we examine the Arabidopsis thaliana homologs of the yeast E2 and E3 enzymes …

Summary Histone H2B monoubiquitination (H2Bub1) is recognized as a crucial eukaryotic
regulatory mechanism that controls a range of cellular processes during both development …
