A Ralstonia solanacearum type III effector alters the actin and microtubule cytoskeleton to promote bacterial virulence in plants.

Cellular responses to biotic stress frequently involve signaling pathways that are conserved across eukaryotes. These pathways include the cytoskeleton, a proteinaceous network that senses external cues at the cell surface and signals to interior cellular components. During biotic stress, dynamic cytoskeletal rearrangements serve as a platform from which early immune-associated processes are organized and activated.

A chemical genetic screen with the EXO70 inhibitor Endosidin2 uncovers potential modulators of exocytosis in Arabidopsis.

Exocytosis plays an essential role in delivering proteins, lipids, and cell wall polysaccharides to the plasma membrane and extracellular spaces. Accurate secretion through exocytosis is key to normal plant development as well as responses to biotic and abiotic stresses. During exocytosis, an octameric protein complex named the exocyst facilitates the tethering of secretory vesicles to the plasma membrane.

Synthesis and crystal structure of 2,9-di-amino-5,6,11,12-tetra-hydro-dibenzo[,]cyclo-octene.

The - form of di-amino-dibenzo-cyclo-octane (DADBCO, CHN) is of inter-est as a negative coefficient of thermal expansion (CTE) material. The crystal structure was determined through single-crystal X-ray diffraction at 100 K and is presented herein.

UK PID Patients: Overview of perception on IgRT and infections using short survey.

Immunoglobulin replacement therapy (IgRT) has advanced over the years and is used to treat many patients with primary immunodeficiencies reducing the number of infections and the burden of disease. We investigated the perception of IgRT in two patient groups (UKPIPS and PID UK) and their condition through a short survey. The survey was a multiple-choice short survey consisting of 20 questions completed either online or on paper.

Cooperative actin filament nucleation by the Arp2/3 complex and formins maintains the homeostatic cortical array in Arabidopsis epidermal cells.

Precise control over how and where actin filaments are created leads to the construction of unique cytoskeletal arrays within a common cytoplasm. Actin filament nucleators are key players in this activity and include the conserved actin-related protein 2/3 (Arp2/3) complex as well as a large family of formins. In some eukaryotic cells, these nucleators compete for a common pool of actin monomers and loss of one favors the activity of the other.
