ABSTRACT = {The Endosperm Balance Number (EBN) is an important concept for potato breeding and has evolutionary importance in tuber-bearing <i>Solanum</i> species. The EBN is part of the post-zygotic hybridization barriers in the group and represents a reproductive isolating mechanism. Few genes have been proposed to be involved in its genetic control; until now, however, neither specific genes nor its molecular basis have been well established. Histological observations of embryo and endosperm development in inter-EBN crosses in tuber-bearing <i>Solanum</i> revealed phenotypes similar to those recently described in <i>Arabidopsis</i> seed mutants. The common feature between them is that the endosperm nuclei become greatly enlarged and that embryos are arrested at the globular stage. The proteins encoded by the <i>Arabidopsis TITAN</i> genes are related to chromosome dynamics and cell division. Based on the sequence of <i>titan</i> mutants, genes in potato species related to cell cycle and microtubule assembly were isolated. In this article a perspective model is proposed to explore the utility of <i>Arabidopsis</i> mutants associated with cell cycle control as a tool to elucidate the molecular basis of EBN in potato. Further research focused on the expression pattern of these genes in intra- and interEBN crosses in potato species will be performed.},
