Abstract: A auto-incompatibilidade (AI) é a incapacidade de uma planta fértil formar sementes quando fertilizada por seu próprio pólen. É um mecanismo fisiólogico, com base genética, que promove a alogamia, e tem despertado a atenção de geneticistas e melhoristas de plantas. Atualmente, a ênfase nas pesquisas está na identificação e entendimento dos processos moleculares e celulares que levam ao reconhecimento e à rejeição do pólen auto-incompatível, incluindo a identificação, localização e seqüenciamento das proteínas,… Show more

“…Further studies are needed to technically assess the compatibility between genotype of Coffea canephora, in order to identify the interaction of the materials for planting indication to farmers. Knowledge of compatibility or self-incompatibility between genotypes allows for increased productivity and final uniformity in Coffee cultivation (Ferrão et al, 2017;Schifino-Wittmann & Dall'agnol, 2002).…”

“…In addition, it should be considered that most Brassica species are self-incompatible; therefore, insect visits are necessary for seed production [6,29]. In Brassica species with auto incompatibility (AI), incompatible pollen grains barely germinate on stigma and, when germinated, their pollen tubes fail to grow on papillary cells on the stigmatic surface [30]. Self-incompatibility is a widespread mechanism in flowering plants that prevent self-fertilization.…”

“…The ornamental potential of the genus is highly valued in Europe and North America and many of the varieties used for this purpose are derived from interspecific hybrids (Abreu et al, 2009). Interspecific hybrids are comparatively easy to generate in this genus because of weak reproductive barriers and weak self-incompatibility; these characteristics are a hallmark of the genus (Schifino-Wittmann and Dall'Agnol, 2002). In general, interspecific hybridization has been the main strategy used for breeding ornamental Passiflora varieties and for the improvement of quantitative and qualitative characteristics of the plants and the development of genotypes with unique characteristics for the ornamental plant market (Abreu et al, 2009;Belo, 2010;Santos et al, 2012).…”
