Abstract:—The cytoplasmatic inheritance of organellar DNA in land plants may occur via three different modes: uniparentally maternal, biparentally and uniparentally paternal. In most angiosperms, the chloroplast is inherited maternally via seeds, whereas in gymnosperms the paternal mode (via pollen) is prevailing. Although it is commonly assumed that plastids are inherited maternally also in Bromeliaceae, molecular evidence for this hypothesis is still lacking. To study the mode of chloroplast inheritance within the genus Fosterella (Pitcairnioideae) via molecular fingerprinting, we developed a novel set of 24 chloroplast microsatellite markers (cpSSRs) using 454 pyrosequencing technology. A subset of these markers was used to genotype the parents and several plants each of the F1 generation derived from seven inter- and two intraspecific crosses, involving the four species F. christophii, F. micrantha, F. villosula, and F. rusbyi. All crosses were performed by hand-pollination under greenhouse conditions. At each cpSSR locus, the banding patterns obtained after high-resolution polyacrylamide gel electrophoresis clearly indicate a maternal inheritance of plastids in each of the analysed crosses.
