• Golgi Traffic and Integrity Depend on N-Myristoyl Transferase-1 in Arabidopsis

  

  Posted on May. 21, 2013

  A microscopy screen for endomembrane defects identified an Arabidopsis N-myristoyltransferase (NMT1) mutant exhibiting reduced activity of the expressed protein. Characterization of this mutant highlights a post-embryonic role for NMT1 in the functional and morphological integrity of the Golgi, predominantly challenging the Golgi membrane/cytosol partitioning of ADP-ribosylation factors (Arfs).

   

• Cytoskeleton-Dependent Endomembrane Organization in Plant Cells: An Emerging Role for Microtubules

  

  Posted on May. 13, 2013

  This review provides an overview of current knowledge on actin-mediated organelle movement within the secretory pathway of plant cells and a report on recent and exciting findings that support a critical role of microtubules in plant cell development in fine-tuning the positioning of Golgi stacks, as well as their involvement in cellulose synthesis and auxin polar transport. 

• Negative Feedback Control of Jasmonate Signaling by an Alternative Splice Variant of JAZ10

  

  Posted on May. 13, 2013

  A transcriptional regulator generated by alternative splicing uses a cryptic binding site to negatively regulate bHLH-type transcription factors that promote jasmonate responses.

• Pseudomonas syringae infection assays in Arabidopsis

  

  Posted on May. 6, 2013

  Pseudomonas syringae pv. tomato DC3000 (Pst DC3000) is a Gram-negative bacterial pathogen that causes bacterial speck disease of tomato (Solanum lycopersicum) and Arabidopsis thaliana and has become an integral part of molecular and biochemical studies of host-pathogen interactions.  Here, we provide examples of methods that have been useful for the elucidation of the role of COR/JA signaling in disease including assays for JAZ protein degradation and expression of JA response genes.
