“…The best known case of such an interaction between the cytoplasm of one species and the nuclear genes of another is that met with in the genus Epilobium and worked out in great detail by MICHAELIS (1954). Reciprocal differences in plastid in Oenothera have also been shown by RENNER (1929; vide MICHAELIS 1954) to be dependent on cytoplasmic factors. Similar cytoplasmic differences have been shown to occur between different species of Solanum (see Section 3C).…”

“…However, such relationships have perhaps never been so systematically investigated as by Michaelis (1954), who reported on the results of a large series of reciprocal crosses and backcrosses between some 10 species of annual Epilobium. Without a detailed embryological investigation, it is not always easy to distinguish this type of seed failure from seed incompatibility.…”

“…However, the pattern of male sterility observed does not readily fit with the expectations of simple models of epistatic breakdown in hybrids (Turelli and Orr 2000). Because the stunted appearance of sterile anthers resembles the anther reductions in females of gynodioecious members of the Caryophyllaceae (e.g., Desfeux et al 1996), one attractive explanation is a mismatch between cytoplasmic male sterility (CMS) and nuclear restorer genotypes in hybrids (e.g., Michaelis 1954;Levy 1991). However, because the reciprocal classes of F 1 hybrids were equally affected, this mechanism would require that the selfer and outcrosser populations have separate and incompatible CMS-restorer systems.…”

The genetic architecture of floral traits involved in the evolution of self-pollination provides a window into past processes of mating system divergence. In this study, we use two generations of crosses between highly selfing and predominantly outcrossing populations of Arenaria uniflora (Caryophyllaceae) to determine the minimum number, average dominance relationships, and pleiotropic effects of genetic factors involved in floral divergence. Comparison of the F1 and F2 phenotypic means with the expectations of a completely additive model of gene action revealed a primarily additive genetic basis for floral characters associated with mating system variation. The exception was flower life span, which showed partial dominance of the outcrosser phenology. In contrast to similarly divergent species, the substantial differences in flower size between these A. uniflora populations appear to involve relatively few genes of large effect (minimum number of effective factors = 2.2 +/- 2.8 SE). In addition, correlations among traits in the F2 generation indicate that pleiotropy may be an important feature of the genetic architecture of floral evolution in A. uniflora. The evolution of selfing via major modifiers of floral morphology is consistent with other evidence for ecological selection for preemptive self-pollination in A. uniflora. Analyses of the genetic basis of autonomous selfing were complicated by hybrid breakdown in both F1 and F2 generations. Only F1 hybrids showed reductions in female fertility, but about 30% of F1 and F2 hybrids exhibited partial or complete male sterility. Male sterile flowers were characterized by short stamens, reduced petals, and a lack of protandry, as well as indehiscent anthers. This morphological breakdown mimics environmental disruptions of floral development and may result from novel genic interactions in hybrids.
