Abstract
U ovom radu je istraživan utjecaj stresa sušom i visokim intenzitetom svjetlosti na ekspresiju D1 podjedinice fotosustava II (PSII), PsbO podjedinice kisik razvijajućeg kompleksa (OEC) i velike podjedinice (LSU) enzima Rubisco u klijancima ječma (Hordeum vulgare L.) kultivara Panonac. Klijanci ječma su izloženi stresu izazvanom sušom u trajanju od 14 dana te visokom intenzitetu svjetlosti u trajanju od 4, odnosno 11 sati u klima komori. Kako bi se odredila količina ispitivanih fotosintetskih proteina, proteini su razdvojeni denaturirajućom elektroforezom u poliakrilamidnom gelu (SDS-PAGE) nakon čega su prenešeni na nitroceluloznu membranu (Western blot) te detektirani specifičnim protutijelima. Izlaganje stresu izazvanom sušom nije doveo do snažnije degradacije sva tri ispitivana fotosintetska proteina. Izlaganje stresu uzrokovanom visokim intenzitetom svjetlosti pokazao je snažniju degradaciju u odnosu na izlaganje suši za sva tri ispitivana proteina. Kraće izlaganje visokom intenzitetu svjetlosti (4h) izazvalo je jaču degradaciju D1 i LSU podjedinice u odnosu na dugotrajnije izlaganje (11h) ovom tipu stresa. Dobiveni rezultati upućuju na to da je izabrana sorta ječma pokazala manju osjetljivost na sušu u odnosu na visoki intenzitet svjetlosti.
Abstract (english)
In this thesis, the effect of stress, trough drought and high light intensity, on the expression of D1 subunit of photosystem II, the PsbO subunit of the oxygen-evolving complex (OEC), and the large subunit (LSU) of the Rubisco enzyme in barley (Hordeum vulgare L.) cultivar Panonac was investigated. e. Barley seedlings were exposed to 14 days of drought stress and to high light intensity stress in the climate chamber in duration of 4 and 11 hours. To determine the amount of examined photosynthetic proteins, denaturing polyacrylamide gel electrophoresis (SDS-PAGE) was used for their separation followed by the transfer to a nitrocellulose membrane (Western blot) and detection with specific antibodies. Exposure to drought induced stress did not result in significant degradation of any of three examined photosynthetic proteins. Exposure to stress caused by high light intensity showed stronger degradation compared to drought exposure in all three proteins. Shorter exposure to high light intensity (4h) caused more degradation of the D1 and LSU subunits when compared to a longer exposure (11h) to this type of stress. The results obtained indicate that the selected cultivar of barley showed a lower sensitivity to drought compared to the high light intensity stress.
