Summary
This 1983 laboratory study induced mutants of the soil-borne fungal pathogen Fusarium solani that were insensitive to tomatine, a naturally occurring plant defence compound in solanaceous crops. The researchers compared the virulence and aggressiveness of tomatine-resistant mutants against wild-type strains on tomato fruits and pea plants, likely exploring the role of this plant chemical in disease resistance. The work contributes to understanding how pathogens evolve tolerance to plant secondary metabolites and the relevance of such defences to crop protection.
Regional applicability
Fusarium solani is a globally distributed soil-borne pathogen affecting solanaceous crops including tomato. The findings may inform United Kingdom horticultural disease management, though the study's laboratory setting and 1983 context (before modern molecular tools) require careful interpretation for current UK practice.
Key measures
Tomatine sensitivity of fungal mutants; pathogenicity and aggressiveness metrics on tomato and pea tissues
Outcomes reported
The study induced and characterised Fusarium solani mutants with reduced sensitivity to tomatine (a plant antimicrobial compound) and assessed their pathogenicity and aggressiveness on tomato fruits and pea plants.
