Item MOŞTENIREA GENELOR Rf LA DIVERSE GENOTIPURI DE FLOAREA-SOARELUI(CEP USM, 2010) Duca, Maria; Port, Angela; Midoni, Andrei; Anisimova, Irina; Rotaru, TudorResearch on four sources of pollen fertility restoration (I1-I3, F1, F2 şi BC1) revealed that this character was controlledin three cases (Drofa, Valentino and Sumbred 254) by one single dominant gene and in one case (Xenia) by two non-allelic dominant genes RfItem ANALIZA COMPARATIVĂ A PROTEINELOR CODIFICATE DE GENELE SISTEMULUI ASC-Rf(CEP USM, 2009) Midoni, AndreiThis work focussed on a comparative analysis of the codified proteins of the CMS-Rf system, having as purpose to find certain correlations between them and some specific properties of polypeptidesItem UNELE PARTICULRITĂŢI DE INTERACŢIUNE NUCLEU – CITOPLASMĂ ÎN CADRUL SISTEMELOR ASC–Rf(CEP USM, 2009) Midoni, AndreiThis work focused on a complex study of various modalities of nucleo – cytoplasmic interaction through the prismof CMS-Rf systems of plants. Therewith we tried to understand different way of suppression of cytoplasmaticale malesterility phenotype.Item MECANISME SPOROFITICE ŞI GAMETOFITICE DE RESTAURARE A FERTILITĂŢII(CEP USM, 2008) Midoni, AndreiIn this study we analyzed two mechanisms of restoring of fertility in sunflower CMS-Rfsystem. Pollen staining with 1% I-KI allows identifying the segregation of viable pollen,which help us to observe what kind of fertility system is (sporophytic or gametophytic).
