    Regulace genů kódujících proteiny fotosyntetických antén u řas v proměnném světelném prostředí

  • Annotation in Czech

    Fotosyntéza je regulována na různých úrovních v závislosti na intenzitě fluktuujících světla, teploty a dostupnosti živin. Jednou z úrovní regulace je změna buněčné pigmentace, spojená se syntézou a degradací proteinů světlosběrných antén. Světlosběrné anténní komplexy eukaryotních řas se rozdělují podle toho, jaké sekundární pigmenty jsou v anténách navázány (LHC pro chla/b, FCP pro chla/c a fucoxanthin, PCP u chla a peridininu). Světlosběrné antény obsahují několik homologních proteinů kódovaných v jádře. Ačkoliv přesné důvody pro multiplicitu LHC proteinů nejsou dosud jasné, předpokládá se, že každý z těchto proteinů má jednoznačnou funkci. Téměř nic není známo a) o mechanismech regulace světlosběrných antén v přirozených podmínkách proměnné intenzity ozářenosti, b) o rozdílech v regulaci LHC, FCP a PCP komplexů, c) o regulaci jednotlivých homologních proteinů. Tyto problémy budeme v navrhovaném projektu studovat pomocí moderních metod molekulární biologie.
