Pseudomonas avellanae

Pseudomonas avellanae is a bacterial species that is pathogenic to plants, specifically the hazelnut tree. It is a member of the genus Pseudomonas, a diverse group of bacteria known for their metabolic versatility and ability to thrive in a wide range of environments.

Taxonomy

Pseudomonas avellanae belongs to the Pseudomonas genus, which is part of the Pseudomonadaceae family. This family is within the order Pseudomonadales, which falls under the class Gammaproteobacteria. Gammaproteobacteria is a class within the phylum Proteobacteria, a major group of Gram-negative bacteria.

Pathogenicity

Pseudomonas avellanae is known to cause bacterial canker in hazelnut trees. The disease is characterized by the formation of cankers on the branches and trunk of the tree, leading to wilting and death of the affected parts. The bacteria can be spread through rain splash, wind, and contaminated pruning tools.

Management

Control of Pseudomonas avellanae involves a combination of cultural practices and chemical treatments. Cultural practices include pruning and removal of infected branches, while chemical treatments involve the use of copper-based fungicides and antibiotics.

Research

Research on Pseudomonas avellanae is focused on understanding its pathogenicity mechanisms and developing effective control strategies. This includes studying its genome to identify genes involved in pathogenicity, and testing different chemical and biological control agents for their efficacy against the bacteria.
