Main conclusion In this paper, an interaction model of apomixis-related genes was
constructed to analyze the emergence of apomictic types. It is speculated that apomixis …

Approximately 70% of the angiosperm species are polyploid, an important phenomenon in
the evolution of those plants. But ploidy estimates have often been hindered because of the …

Seed production is the key factor for maintaining plant population renewal and development.
Because of pollination limitations and other factors, orchids, especially rewardless ones …

Breeding systems have been associated with polyploidization and genomic change, which
have a central role in the diversification of Angiosperms. Polyploidy commonly leads to …

Apomixis is a difficult-to-analyse trait with a complex molecular basis and a substantive
effect on the biology of a species. Thus, apomixis is an interesting characteristic for …

Apomixis, the asexual formation of embryos and seeds, occurs in approximately 18% of
angiosperm families. Melastomataceae exhibits a remarkable number of apomictic species …

Some tropical Bignoniaceae form sporophytic apomictic polyploid complexes are similar to
better studied temperate plants. Handroanthus ochraceus is a widely distributed Neotropical …

Polyploidization is common among angiosperms and might induce typically allogamous
plants to become autogamous (self-compatible, relying on sexual self-fertilization) or …

Late-acting self-incompatibility (LSI) has been defined as a genetically controlled self-
sterility mechanism that prevents seed set by selfing, despite normal pollen tube growth and …

In neotropical ecosystems, genetic variability and diversity of plant species seem to be
generated and maintained by sexual reproduction. However, apomixis appears as an …
