Reproductive systems of Hohenbergia Schult. & Schult.f. (Bromelioideae: Bromeliaceae) endemic to the Atlantic forest

Nordic Journal of Botany, Volume 2025, Issue 9, September 2025.
Many species of the Bromeliaceae are under threat due to the fragmentation and anthropogenic pressure affecting the Atlantic Forest highlight the need to conservation efforts. The genus Hohenbergia deserves special attention in this context, as the Hohenbergia stellata complex includes endemic species that rely on diverse reproductive strategies, which

Polyamines Involved in Regulating Self-Incompatibility in Apple

, 2021
Apple exhibits typical gametophytic self-incompatibility, in which self-S-RNase can arrest pollen tube growth, leading to failure of fertilization. To date, there have been few studies on how to resist the toxicity of self-S-RNase.

Proteomics Approaches Advance Our Understanding of Plant Self-Incompatibility Response

, 2016
Self-incompatibility (SI) in plants is a genetic mechanism that prevents self-fertilization and promotes out-crossing needed to maintain genetic diversity.

PollenCALC: Software for estimation of pollen compatibility of self-incompatible allo- and autotetraploid species

BMC Bioinformatics, 2012
Background Self-incompatibility (SI) is a biological mechanism to avoid inbreeding in allogamous plants. In grasses, this mechanism is controlled by a two-locus system (S-Z).

Cellular mechanisms for pollen tube growth inhibition in gametophytic self-incompatibility

, 2006
Self-incompatibility (SI) is a mechanism used by angiosperms to prevent self-fertilization. Here we review current knowledge of two different gametophytic SI systems at the cellular level, revealing different mechanisms that interfere with pollen tube ...

Gametophytic incompatibility in pome and stone fruits: genes controlling S-locus.

, 2012
Angiosperms are the most prevalent and evolutionarily advanced group of plants. A critical step for the success of flowering plants was the wide promotion of cross-fertilization as reproductive strategy. The Gametophytic Self-Incompatibility (GSI) system

Apple Pollination Biology for Stable and Novel Fruit Production: Search System for Apple Cultivar Combination Showing Incompatibility, Semicompatibility, and Full-Compatibility Based on the S-RNase Allele Database

International Journal of Agronomy, 2014
Breeding and cultivation of new apple cultivars are among the most attractive and important issues for apple researchers. As almost all apple cultivars exhibit gametophytic self-incompatibility (GSI), cross-pollination between genetically different ...

Evolutionary genetics of an S-like polymorphism in Papaveraceae with putative function in self-incompatibility.

PLoS ONE, 2011
BackgroundPapaver rhoeas possesses a gametophytic self-incompatibility (SI) system not homologous to any other SI mechanism characterized at the molecular level.
