e3“Multi-locus phylogeny of the RNA polymerase II second largest subunit (rpb2), putative F-box-domain-containing protein (ASA-10), and putative histone-like transcription factor (ASA-19) confirmed the occurrence of both A. alternata and A. arborescens species complexes along with A. longipes and A. postmessia on symptomatic tomatoes”

Other claims from this paper (11)
- Observation Tomato-associated Alternaria spp. strains showed considerable variation in phenotypic diversity.
- Observation Tomato-associated Alternaria spp. strains were non-pathogenic to their host of origin.
- Observation Tomato-associated Alternaria strains lacked the AAL-toxin biosynthesis gene ALT1.
- Observation Multi-locus phylogeny confirmed the occurrence of both A. alternata and A. arborescens species complexes on symptomatic tomatoes.
- Observation 16 multi-locus haplotypes were assigned in the alternata lineages.
- Observation 6 multi-locus haplotypes were assigned in the arborescens lineages.
- Observation DNA polymorphism analysis of rpb2, ASA-10 and ASA-19 loci revealed a high level of genetic diversity in section Alternaria.
- Observation The number of SNPs and haplotypes varied among loci and lineages studied.
- Mechanism Discordant single-gene tree topologies suggested potential recombination between phylogenetic lineages in section Alternaria.
- Observation Discordant topologies indicated putative alternata-arborescens and alternata-longipes hybrids.
- Observation Global rpb2 analysis confirmed that major haplotypes described from tomatoes were shared among other hosts of origin.
