Members of the PHO1 gene family show limited functional redundancy in phosphate transfer to the shoot, and are regulated by phosphate deficiency via distinct pathways.
TLDR
Although transfer of Pi to the root xylem vessel is primarily mediated by PHo1, the homologue PHO1;H1 also contributes to Pi loading to the Xylem, and that the two corresponding genes are regulated by Pi deficiency by distinct signal transduction pathways is revealed.

CBOL Protist Working Group: Barcoding Eukaryotic Richness beyond the Animal, Plant, and Fungal Kingdoms
A group of protist experts proposes a two-step DNA barcoding approach, comprising a universal eukaryotic pre-barcode followed by group-specific barcodes, to unveil the hidden biodiversity of…

Characterization of an Arabidopsis-Phytophthora pathosystem: resistance requires a functional PAD2 gene and is independent of salicylic acid, ethylene and jasmonic acid signalling.
TLDR
Resistance of Arabidopsis against P. porri appears to depend on unknown defence mechanisms that are under the control of PAD2, which is similar to that seen in agronomically important diseases caused by Phytophthora species.

Phylogenetic analysis and real time PCR detection of a presumbably undescribed Peronospora species on sweet basil and sage.
TLDR
The morphology of this presumably undescribed species of Peronospora is described and illustrated and PCR primers for real time PCR analysis have been developed for the specific detection of this downy mildew pathogen from infected tissues or seeds.

Insight into trade-off between wood decay and parasitism from the genome of a fungal forest pathogen.
TLDR
It is established that saprotrophic wood decay and necrotrophic parasitism involve two distinct, yet overlapping, processes that show a trade-off in terms of constrained carbohydrate decomposition and membrane transport capacity during interaction with living hosts.

Rapid Detection of Ceratocystis platani Inoculum by Quantitative Real-Time PCR Assay
TLDR
The combination of airborne trapping and real-time quantitative PCR assay provides a rapid and sensitive method for the specific detection of a C. platani inoculum and may be used to identify the period of highest risk of pathogen spread in a site, thus helping disease management.

Multiple alien Phytophthora taxa discovered on diseased ornamental plants in Spain
TLDR
The plant trade is unwittingly accelerating the worldwide spread of well-known and new or undescribed Phytophthora species and creating novel niches for emerging pathogens and the extent of this global issue at the local scale was reflected.

Intraspecific and within-isolate sequence variation in the ITS rRNA gene region of Pythium mercuriale sp. nov. (Pythiaceae).
TLDR
Sixteen Pythium isolates from diverse hosts and locations, which showed similarities in their morphology and sequences of the internal transcribed spacer region of their rRNA gene, were investigated and revealed high levels of heterozygosity as well as polymorphism within and between isolates.
