Since the discovery of SUMO twenty years ago, SUMO conjugation has become a widely
recognized post-translational modification that targets a myriad of proteins in many …

Highlights•Over 1000 mostly nuclear proteins are targets of SUMOylation in
Arabidopsis.•Stress-induced SUMO addition is important for abiotic and biotic stress …

Sperm chromatin is typically transformed by protamines into a compact and transcriptionally
inactive state,. Sperm cells of flowering plants lack protamines, yet they have small …

Chloroplasts are the site of numerous biochemical reactions including photosynthesis, but
they also produce reactive oxygen species (ROS) that negatively affect chloroplast integrity …

Wide crosses result in postzygotic elimination of one parental chromosome set, but the
mechanisms that result in such differential fate are poorly understood. Here, we show that …

Abstract The transcription of 18S, 5.8 S, and 18S rRNA genes (45S rDNA), cotranscriptional
processing of pre-rRNA, and assembly of mature rRNA with ribosomal proteins are the …

Alternation between morphologically distinct haploid and diploid life forms is a defining
feature of most plant and algal life cycles, yet the underlying molecular mechanisms that …

Chromatin plays a crucial role in genome compaction and is fundamental for regulating
multiple nuclear processes. Nucleosomes, the basic building blocks of chromatin, are …

Background Eukaryotic genomes are partitioned into euchromatic and heterochromatic
domains to regulate gene expression and other fundamental cellular processes. However …

Silencing of transposable elements (TEs) drives the evolution of numerous redundant
mechanisms of transcriptional regulation. Arabidopsis MBD5, MBD6, and SILENZIO act as …
