Perturbation of H3K27me3-Associated Epigenetic Processes Increases Agrobacterium-Mediated Transformation

Improving the efficiency of Agrobacterium-mediated transformation remains a major challenge for many plant species, particularly if the full potential of genome editing is to be realized. Iwakawa et al. provide evidence that transformation efficiency could be enhanced through manipulation of H3K27me3-dependent epigenetic regulation. View article...

GABA Uptake Represses Gene Expression in Pseudomonas syringae pv. tomato DC3000

McCraw et al. demonstrate that the GABA permease GabP provides the primary mechanism for GABA uptake by DC3000 and that a gabP deletion mutant is insensitive to GABA-mediated-repression of T3SS expression. Open Access.

Immuno-Suppressive Aphid Saliva Protein Delivered into Cytosol of Mesophyll Cells During Feeding

Mugford and colleagues illustrate how immunogold labeling can provide information about the subcellular localization of effector proteins, complementing functional studies and enhancing the understanding of effector mode of action. Open Access.

Bacillus mojavensis RRC101 Lipopeptides Provoke Changes During Antagonism Against Fusarium verticillioides

Blacutt et al. explore molecular interactions between the maize-endophytic bacterium Bacillus mojavensis and the mycotoxigenic fungus Fusarium verticillioides. Bacterial lipopeptides are implicated in both antifungal activity and fungal toxin production.

Arabidopsis Proline Dehydrogenase Contributes to Flagellin-Mediated PAMP-Triggered Immunity by Affecting RBOHD

​Fabro and colleagues examine how processes that alter the mitochondrial electron transport chain (mETC) influence establishment of PAMP-triggered immunity (PTI) with emphasis on the effect of the enzyme proline dehydrogenase.

​Poplar–Root-Knot Nematode Interaction: A Model for Perennial Woody Species
Baldacci-Cresp and colleagues describe a new system for studying interactions between root-knot nematodes and trees. Nematodes exercised conserved strategies to reproduce and invade perennial plants, and poplar was identified as a model host for studying traits of tree–nematode interactions.

Peptidoglycan-Remodeling Enzyme Critical for Bacteroid Differentiation in Bradyrhizobium spp. During Legume Symbiosis

Gully and colleagues provide an elegant genetic demonstration of the important role played by the bacterial peptidoglycan layer in the symbiosis between Bradyrhizobium and Aeschynomene species of legumes.

Genome-Wide Association Study (GWAS) Identifies Novel Candidate Genes in Natural Field Populations of Fusarium graminearum

Talas et al. use GWAS and phenotyping under field conditions to identify candidate genes associated with aggressiveness, mycotoxin production, and fungicide resistance in the head blight pathogen, Fusarium graminearum.

Phytopathogen Genome Announcement: Draft Genome Sequences of 62 Pseudomonas syringae Type and Pathotype Strains
Thakur and colleagues announce the availability of draft genomes for 62 strains of the bacterium Pseudomonas syringae, a diverse species-complex that affects many important crops. These genomes will be valuable resources for exploring many aspects of bacterial phytopathology.

Focus on Noncoding RNA Regulation of Plant–Microbe Interactions
The March 2016 Focus Issue highlights exciting research on noncoding RNA regulation of plant–microbe interactions. As such, this issue comprises a fitting tribute to our deeply missed colleague, Biao Ding.

MPMI Editor's Pick: Characterization of RNAi-Transgenic Tomato Plants with Resistance to Tomato Yellow Leaf Curl Virus (TYLCV)
Fuentes and colleagues describe the benefits and limitations of a transgenic approach for RNAi-based protection against TYLCV. They demonstrate that resistance in transgenic tomato is stable over multiple generations and effective under field conditions. Importantly, they also use transcriptomics to discover probable off-target effects of the transgene.
