“…geitonogamous pollination; Fig. 8) or flowers from the same morph (intramorph cross-pollination, as in heterostyly; see topic 1.2) (Li & Newbigin 2002;Glover 2007;Rea & Nasrallah 2008). Self-incompatibility (SI) has been studied in several angiosperm families and is possibly controlled by a single locus, the "S" locus (Nettancourt 2001).…”

“…Gametophytic self-incompatibility occurs in flower homomorphic plants and is controlled by a single locus S containing several alleles with absence of dominance. In this system, the pollen grain may express one or more alleles present on this locus, with the expression of incompatibility substances controlled by both ovules and pollen tubes, so that the recognition of equal alleles causes incompatibility and prevents fertilization (Li & Newbigin 2002;Glover 2007;Gibbs 2014).…”

“…The GSI system was extensively investigated in the family Solanaceae, being initially described in the genus Nicotiana (Glover 2007). It is widely distributed among angiosperms, being found in about 90 families such as Fabaceae, Papaveraceae, Plantaginaceae, Rosaceae, Scrophulariaceae and Solanaceae (Li & Newbigin 2002;Franklin-Tong & Franklin 2003).…”

Towards a unified terminology for angiosperm reproductive systems

Angiosperms display an enormous diversity of forms, functions and strategies when it comes to reproduction. This multiplicity has been translated into several terminological concepts and contexts, which have facilitated further research. On the other hand, the use of terms that address the reproduction of flowering plants has been shown to be inconsistent in the literature, complicating communication among specialists. Key terms, such as "reproductive system", "mating system" and "sexual system", among others, have been frequently cited as synonyms, and even used in different circumstances. This review proposes to establish a consistent nomenclatural classification in the field of angiosperms reproductive biology in order to facilitate communication among researchers. Specific terms related to angiosperm reproduction are conceptualized and distributed into five general systems: four related to sexual reproduction (sexual, floral, incompatibility and mating systems); and one related to asexual reproduction (apomictic systems). Our proposal is not to establish a natural classification, but rather to provide a general overview of the main concepts that were grouped here in an artificial and functional manner. Our aim is to advance the field of reproductive biology of angiosperms with consistent and well-defined applications of relevant terminologies.
