Threatened by Alder : A Histological Study of Roots.

Alder dieback remains a major problem in European alder stands and its spread continues to threaten their existence. The causal agent of this disease is the so-called alder species complex, which includes the hybrid × and its parental species and . Little is known about the survival of these species in alder.

Unravelling hybridization in Phytophthora using phylogenomics and genome size estimation.

The genus Phytophthora comprises many economically and ecologically important plant pathogens. Hybrid species have previously been identified in at least six of the 12 phylogenetic clades. These hybrids can potentially infect a wider host range and display enhanced vigour compared to their progenitors.

Foliar Blight and Shoot Dieback Caused by Phytophthora ramorum on Viburnum tinus in the Pistoia Area, Tuscany, Central Italy.

In spring 2013, pot-grown Viburnum tinus plants shipped to an ornamental nursery in Pescia (Pistoia, central Italy, 287 m a.s.l.

First Report of Dieback on Euonymus fortunei Caused by Cylindrocladiella parva in Germany.

In August 2011, a severe shoot dieback was observed on several hundred plants of 1-year-old Euonymus fortunei cv. Emerald 'n Gold in a nursery in Lower Saxony and on a cemetery in Berlin. Single shoots or the whole plant were affected.

Development of a lab-on-a-chip device for diagnosis of plant pathogens.

A lab-on-a-chip system for rapid nucleic acid-based analysis was developed that can be applied for diagnosis of selected Phytophthora species as a first example for use in plant pathology. All necessary polymerase chain reaction process (PCR) and hybridization steps can be performed consecutively within a single chip consisting of two components, an inflexible and a flexible one, with integrated microchannels and microchambers. Data from the microarray is collected from a simple electrical measurement that is based on elementary silver deposition by enzymatical catalyzation.
