Two winter triticale (x Triticosecale Wittmack) model cultivars: Hewo (tolerant to pink snow mould) and Magnat (sensitive) were used to test the effect of cold-hardening (4 weeks at 4°C) on soluble ≤50 kDa protein profiles of the seedling leaves. The presence and abundance of individual proteins were analysed via two-dimensional gel electrophoresis (2-DE) and Surface-Enhanced Laser Desorption/Ionization Time-of-Flight (SELDI-TOF). Up to now, no proteomics analysis of triticale response to hardening has been performed. Thus, the present paper is the first in the series describing the obtained results. In our experiments, the exposure to the low temperature-induced only quantitative changes in the leaves of both cultivars, causing either an increase or decrease of 4–50 kDa protein abundance. Among proteins which were cold-accumulated in cv. Hewo’s leaves, we identified two thioredoxin peroxidases (chloroplastic thiol-specific antioxidant proteins) as well as mitochondrial- β-ATP synthase subunit and ADP-binding resistance protein. On the contrary, in hardened seedlings of this genotype, we observed the decreased level of chloroplastic RuBisCO small subunit PW9 and epidermal peroxidase 10. Simultaneous SELDI-TOF analysis revealed several low mass proteins better represented in cold-hardened plants of tolerant genotype in comparison to the sensitive one and the impact of both genotype and temperature on their level. Based on those results, we suggest that indicated proteins might be potential candidates for molecular markers of cold-induced snow mould resistance of winter triticale and their role is worth to be investigated in the further inoculation experiments.

AbstractThe accumulation of pathogenesis-related proteins such as β-1,3-glucanases and chitinases was studied in cold induced snow mould resistance in two Polish cultivars of winter triticale, cv. Hewo and cv. Magnat that substantially differ in resistance to Microdochium nivale. The plants were pre-hardened at 12°C for 10 days and hardened at 4°C for 28 days. Subsequently, cold hardened plants were inoculated with fungal mycelium (M. nivale) and incubated at 4°C for 7 days in dark. Cold acclimatisation resulted in suppression of the total glucanase and chitinases activities in the resistant Hewo as well as sensitive Magnat cultivars that possibly coincides with altered metabolism. However, upon infection with M. nivale the chitinases were markedly induced in the cv. Hewo. At the same time, total β-1,3 glucanases activities did not seem to be affected by fungus in any of the tested triticale cultivars. The pattern and/or the activity of chitinases in plants might be indicative for the resistance/susceptibility against M. nivale.
