Several cultivars of commercial tomato (<i>Solanum lycopersicum</i> var. <i>lycopersicum</i>, <i>SLL</i>) are reported to have a mutation in <i>Asc1</i>, resulting in their susceptibility to AAL-toxin. We evaluated 119 ancestral tomato accessions including <i>S. pimpinellifolium</i> (<i>SP</i>), <i>S. lycopersicum</i> var. <i>cerasiforme</i> (<i>SLC</i>) and <i>S. lycopersicum</i> var. <i>lycopersicum</i> "jitomate criollo" (<i>SLJ</i>) for AAL-toxin susceptibility. Three accessions, <i>SP</i> PER018805, <i>SLC</i> PER018894, and <i>SLJ</i> M5-3, were susceptible to AAL-toxin. <i>SLPlants (Basel, Switzerland)Mutations Found in the <i>Asc1</i> Gene That Confer Susceptibility to the AAL-Toxin in Ancestral Tomatoes from Peru and Mexico.PMC782408526304025, 20KK0133Akagi YElespuru Suna MGCabrera Pintado RMAlberca Cruz OIArie TGuerrero Abad JCTsuzuki RHozum TTorres Arias ICBiondi Thorndike JAFlores Ticona JKotera SAmasifuen Guerra CASaito HPerez ERKodama Mde Baldarrago FCUreta Sierra CHuarhua Zaquinaula MHAragon Caballero LMBlas Sevillano RHKomatsu KGutierrez Reynoso DLfalseMutations Found in the <i>Asc1</i> Gene That Confer Susceptibility to the AAL-Toxin in Ancestral Tomatoes from Peru and Mexico.Tomato susceptibility/resistance to stem canker disease caused by <i>Alternaria alternata</i> f. sp. <i>lycopersici</i> and its pathogenic factor AAL-toxin is determined by the presence of the <i>Asc1</i> gene.
