A remorin from Nicotiana benthamiana interacts with the Pseudomonas type-III effector protein HopZ1a and is phosphorylated by the immune-related kinase PBS1.

Mol Plant Microbe Interact 2019 Apr 23. Epub 2019 Apr 23.

Leibniz-Institut fur Gemuse- und Zierpflanzenbau Grossbeeren/Erfurt eV, 28405, Functional Plant Biology , Theodor-Echtermeyer-Weg 1 , Grossbeeren, Germany , 14979.

The plasma membrane is at the interface of plant-pathogen interactions and thus many bacterial type-III effector proteins (T3Es) target membrane-associated processes to interfere with immunity. The Pseudomonas syringae T3E HopZ1a is a host cell plasma membrane (PM)-localized effector protein that has several immunity associated host targets but also activates effector triggered immunity (ETI) in resistant backgrounds. Although HopZ1a has been shown to interfere with early defense signaling at the PM, no dedicated plasma membrane-associated HopZ1a target protein has been identified until now. Read More

Fitting pieces into the puzzle of type III secretion system gene expression.

J Bacteriol 2019 Apr 22. Epub 2019 Apr 22.

Department of Microbiology and Immunology, University of Iowa

Type III secretion systems (T3SS) are widely distributed in Gram-negative microorganisms and critical for host-pathogen and host-symbiont interactions with plants and animals. Central features of the T3SS are a highly conserved set of secretion and translocation genes and contact-dependence wherein host-pathogen interactions trigger effector protein delivery and serve as an inducing signal for T3SS gene expression. In addition to these conserved features there are also pathogen-specific properties that include a unique repertoire of effector genes and mechanisms to control T3SS gene expression. Read More

Multiple distinct O-Mannosylation pathways in eukaryotes.

Curr Opin Struct Biol 2019 Apr 15;56:171-178. Epub 2019 Apr 15.

Copenhagen Center for Glycomics, Departments of Cellular and Molecular Medicine, Faculty of Health Sciences, University of Copenhagen, Blegdamsvej 3, DK-2200 Copenhagen N, Denmark. Electronic address:

Protein O-mannosylation (O-Man), originally discovered in yeast five decades ago, is an important post-translational modification (PTM) conserved from bacteria to humans, but not found in plants or nematodes. Until recently, the homologous family of ER-located protein O-mannosyl transferases (PMT1-7 in yeast; POMT1/POMT2 in humans), were the only known enzymes involved in directing O-Man biosynthesis in eukaryotes. However, recent studies demonstrate the existence of multiple distinct O-Man glycosylation pathways indicating that the genetic and biosynthetic regulation of O-Man in eukaryotes is more complex than previously envisioned.

Ectopic Dpp signaling promotes stem cell competition through EGFR signaling in the Drosophila testis.

Sci Rep 2019 Apr 16;9(1):6118. Epub 2019 Apr 16.

College of Life Sciences, Capital Normal University, Beijing, 100048, China.

Stem cell competition could select the fittest stem cells and potentially control tumorigenesis. However, little is known about the underlying molecular mechanisms. Here, we find that ectopic Decapentaplegic (Dpp) signal activation by expressing a constitutively active form of Thickveins (Tkv) in cyst stem cells (CySCs) leads to competition between CySCs and germline stem cells (GSCs) for niche occupancy and GSC loss.

Manipulation of oxidative stress responses as a strategy to generate stress-tolerant crops. From damage to signaling to tolerance.

Crit Rev Biotechnol 2019 Apr 16:1-16. Epub 2019 Apr 16.

a Facultad de Ciencias Bioquímicas y Farmacéuticas, Biología del Estrés en Plantas, Instituto de Biología Molecular y Celular de Rosario (IBR-UNR/CONICET) , Universidad Nacional de Rosario (UNR) , Rosario , Argentina.

Plants exposed to hostile environmental conditions such as drought or extreme temperatures usually undergo oxidative stress, which has long been assumed to significantly contribute to the damage suffered by the organism. Reactive oxygen species (ROS) overproduced under stress conditions were proposed to destroy membrane lipids and to inactivate proteins and photosystems, ultimately leading to cell death. Accordingly, considerable effort has been devoted, over the years, to improve stress tolerance by strengthening antioxidant and dissipative mechanisms. Read More
