Última In vivo self-incompatibility response in the wild potato Solanum chacoense bitter JBAG Capurro,M.A; Medina Piles,V; Camadro,E.L. In tuber-bearing Solanum species (potatoes), S-locus mediated self-incompatibility is under gametophytic control. In this system, self-fertilization is avoided when the same S-allele is expressed in both pistil and pollen. Because the ultrastructural details of the self-incompatibility response in this group of species is unknown, the aim of this study was to identify the cellular events involved in this response by using the diploid species S. chacoense Bitter as a model. To this end, pollinations were carried out in two genotypic combinations previously identified as (1) compatible and (2) self-incompatible (self-pollination) for the S-locus. Pollinated pistils were fixed on an hourly basis and observed under a transmission electron microscope to detect...
