Morphology

Pseudomonas + solanacearum

This is a scientific Latin binomial: 'Pseudomonas' signals a genus of bacteria (so the infection/organism sense is clear), while 'solanacearum' is a specialized Latinized species epithet deriving from Solanaceae (plants like tomato/potato) but is not a common English word and is absent from the provided dictionary. Together the parts allow a learner with botanical/taxonomic awareness to infer 'a Pseudomonas that affects solanaceous crops', but the meaning relies on specialist morphological knowledge and is not fully predictable to a general B1 learner.

Etymology

Pseudomonas solanacearum gets its name from scientific words: Pseudomonas comes from 'pseudo' meaning 'false' and 'monas' meaning 'single', a name used for tiny single-celled bacteria, and solanacearum points to the 'Solanaceae' plants like tomatoes, potatoes and tobacco. So the name shows it is a bacterium that attacks those crops and causes 'brown rot'.
