20.500.12556/DiRROS-29168 Differentiating resistance levels and biochemical responses of soybean cultivars infected by diverse Diaporthe species using two inoculation methods Diaporthe spp. are among the most serious pathogens of soybean. Many different Diaporthe species can infect soybean plants. The species differ in their aggressiveness or virulence and in the severity of the damage they cause. Resistance breeding in soybean has been performed for only two Diaporthe species, so far. It would be very advantageous to identify soybean cultivars with resistance against other Diaporthe species as well, both as sources of resistance for breeding and to inform farmers which cultivars should be planted when a given Diaporthe species shows high incidence. We performed greenhouse experiments to differentiate levels of resistance using the Stem Cut and Stem Wound methods for inoculation of the plants with Diaporthe. Symptom severity was rated visually, and at 5 dpi the level of lipid peroxidation (LP), activity of superoxide dismutase (SOD), total phenolics and total flavonoids were measured. Among the four Diaporthe species tested, D. caulivora was most aggressive, followed by D. longicolla. Of the cultivars evaluated, Magnolia exhibited the highest level of resistance with no significant differences observed among the other cultivars. Although biochemical responses could be observed, it was impossible to determine the specific response responsible for elevated resistance in Magnolia. soybean Diaporthe resistance germplasm evaluation Stem Wound inoculation relative treatment effect (RTE) biochemical responses yield stability Phaseolus vulgaris true false true Angleški jezik Latinski jezik Neznano 2026-04-22 14:27:35 2026-04-22 14:27:35 2026-04-23 04:02:15 0000-00-00 00:00:00 2026 0 0 Soavtorji: Kristina Petrović, Jovana Šućur Elez, Marina Crnković, Febina Mathew, Nitha Rafi, Tobias Immanuel Link; Nasl. z nasl. zaslona; Opis vira z dne 22. 4. 2026; str. 1-16 issue 9, [article no.] 1284 Vol. 15 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2026-04-22 633 2223-7747 10.3390/plants15091284 276126979 https://www.mdpi.com/2223-7747/15/9/1284 1 a54c5406-3e46-11f1-a343-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=43597 RAZ_Hosseini_Behnoush_2026.pdf RAZ_Hosseini_Behnoush_2026.pdf 1 1ACCE282515E33DB2F2A5DBEECCBB10E 5528ff6c415254cc18ec40363cf8227dd05c1b92f8a1ada7783e24e163d17f3a bc9e7048-3e46-11f1-a343-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=43598 Kmetijski inštitut Slovenije 0 0 0
