Назив: | Changes in L-phenylalanine ammonia-lyase activity and isoflavone phytoalexins accumulation in soybean seedlings infected with Sclerotinia sclerotiorum | Аутори: | Đorđe Malenčić Jelena Helen Hogervorst Vesna Tepavčević Mira Bursać Biljana Kiprovski Miloš Rajković |
Кључне речи: | Glycine max;Isoflavone phytoalexins;L-phenylalanine ammonia-lyase;Sclerotinia sclerotiorum | Датум издавања: | 1-сеп-2013 | Часопис: | Central European Journal of Biology | Сажетак: | Soybean [Glycine max (L.) Merr.] cultivars (Meli, Alisa, Sava and 1511/99) were grown up to V1 phase (first trifoliate and one node above unifoliate) and then inoculated with Sclerotinia sclerotiorum (Lib.) de Bary under controlled conditions. Changes in L-phenylalanine ammonia-lyase (PAL) activity and isoflavone phytoalexins were recorded 12, 24, 48 and 72 h after the inoculation. Results showed an increase in PAL activity in all four examined soybean cultivars 48 h after the inoculation, being the highest in Alisa (2-fold higher). Different contents of total daidzein, genistein, glycitein and coumestrol were detected in all samples. Alisa and Sava increased their total isoflavone content (33.9% and 6.2% higher than control, respectively) as well as 1511/99, although 48 h after the inoculation its content decreased significantly. Meli exhibited the highest rate of coumestrol biosynthesis (72 h after the inoculation) and PAL activity (48 h after the inoculation). All investigated cultivars are invariably susceptible to this pathogen. Recorded changes could point to possible differences in mechanisms of tolerance among them. © 2013 Versita Warsaw and Springer-Verlag Wien. | URI: | https://open.uns.ac.rs/handle/123456789/8708 | ISSN: | 1895104X | DOI: | 10.2478/s11535-013-0201-1 |
