We hypothesized that the seeds of resistant accession k-1958 <i>Ae. tauschii</i> ssp. <i>strangulata</i> can contain a larger number of metabolites with antifungal activity compared with the seeds of susceptible <i>Ae. tauschii</i> ssp <i>meyeri</i> k-340, which will determine differences in the seed fungal community. Our study emphasizes the differences in the seed metabolome of the studied <i>Ae. tauschii</i> accessions. The resistant accession k-1958 had a higher content of glucose and organic acids, including pyruvic, salicylic and azelaic acid, as well as pipecolic acids, galactinol, glycerol andPlants (Basel, Switzerland)Metabolome and Mycobiome of <i>Aegilops tauschii</i> Subspecies Differing in Susceptibility to Brown Rust and Powdery Mildew Are Diverse.PMC11397189agreement № 075-15-2022-320 dated 20 April 2022Andronov EEChizhevskaya EPKichko AAChikida NNChebotar VKFilippova PSPishchik VNAksenova TSShelenga TVBelousova MHfalseMetabolome and Mycobiome of <i>Aegilops tauschii</i> Subspecies Differing in Susceptibility to Brown Rust and Powdery Mildew Are Diverse.The present study demonstrated the differences in the seed metabolome and mycobiome of two <i>Aegilops tauschii</i> Coss accessions with different resistance to brown rust and powdery mildew.
