Protein activity, abundance, and stability can be regulated by post-translational modification including ubiquitination. Ubiquitination is conserved among eukaryotes and plays a central role in modulating cellular function; yet, we lack comprehensive catalogs of proteins that are modified by ubiquitin in plants. In this study, we describe an antibody-based approach to enrich ubiquitinated peptides coupled with isobaric labeling to enable quantification of up to 18-multiplexed samples.

The Arabidopsis tandem CCCH zinc finger 1 (TZF1) is an RNA-binding protein that plays a pivotal role in plant growth and stress response. In this report, we show that TZF1 contains two intrinsically disordered regions necessary for its localization to stress granules (SGs). TZF1 recruits mitogen-activated protein kinase (MAPK) signaling components and an E3 ubiquitin ligase KEEP-ON-GOING (KEG) to SGs.

Article Synopsis
  • G protein-coupled receptors (GPCRs) are the largest group of cell surface receptors in eukaryotes and are essential for fungi to detect important signals for survival and interactions with other species.* -
  • Fungi lack receptor kinases found in plants and instead rely on GPCRs to activate pathways like cAMP and mitogen-activated protein kinase via G proteins, aiding in nutrient detection and pheromone recognition for growth and reproduction.* -
  • Although research on fungal GPCRs is still developing, particularly in pathogens, some GPCRs have been identified that help fungi sense signals from their hosts, contributing to our understanding of fungal biology.*

Guangdong Provincial Key Laboratory for the Development Biology and Environmental Adaptation of Agricultural Organisms, College of Life Sciences, South China Agricultural University, Guangzhou 510642, China.

Plant cell surface-localized pattern recognition receptors (PRRs) recognize microbial patterns and activate pattern-triggered immunity (PTI). Typical PTI responses include reactive oxygen species (ROS) burst controlled by the NADPH oxidase RESPIRATORY BURST OXIDASE HOMOLOG D (RbohD) and activation of the MAP kinase (MAPK) cascade composed of MAPKKK3/5-MKK4/5-MPK3/6. However, the mechanisms through which PRRs regulate and coordinate these immune responses are not fully understood.
