Distinct immune responses confer partial resistance to Fusarium wilt in tomato landraces.

ABSTRACT:

Main conclusion

Cypriot tomato landraces exhibit partial resistance to Fusarium wilt through distinct jasmonic and salicylic acid-mediated immune responses, offering promising genetic resources for breeding durable tomato cultivars. Fusarium wilt, caused by Fusarium oxysporum f. sp. lycopersici (Fol), is a major constraint on global tomato (Solanum lycopersicum) production, with few sustainable control measures available. This study assessed six Cypriot tomato landraces for resistance to Fol and explored the mechanisms underlying their defense. Pathogenicity assays under controlled growth conditions identified two landraces, ARI00732 and ARI00733, with partial resistance and improved growth performance compared to the susceptible cultivar Ailsa Craig. A second pathogenicity trial u
