Pest categorisation of .

The European Commission requested the EFSA Panel on Plant Health to conduct a pest categorisation of (Ellis & Everh) Sutton, following commodity risk assessments of , , and plants from the UK, in which was identified as a pest of possible concern to the EU. When first described, was a clearly defined fungus of the family Schizoparmaceae, but due to lack of a curated type-derived DNA sequence, current identification based only on DNA sequence is uncertain and taxa previously reported to be this fungus based on molecular identification must be confirmed. The uncertainty on the reported identification of this species translates into uncertainty on all the sections of this categorisation.

Pest categorisation of .

Following an EFSA commodity risk assessment of bonsai plants ( grafted on ) imported from China, the EFSA Plant Health Panel performed a pest categorisation of a clearly defined plant pathogenic fungus of the family Pestalotiopsidaceae.

Combined Transcriptomic and Metabolomic Analysis Reveals Insights into Resistance of Arabidopsis Mutant against the Phytopathogenic Fungus .

The wilt-inducing strains of are responsible for severe damage to many economically important plant species. The most cost-effective and environmentally safe method for the management of Fusarium wilt is the use of resistant cultivars when they are available. In the present study, the Arabidopsis genotype with disruptions in the () gene, which encodes the major hydrolytic enzyme that degrades starch to maltose, had significantly lower susceptibility to f.
