Cross-incompatibility and self-incompatibility: unrelated phenomena in wild and cultivated potatoes?
(NRC Re, 2017-10)
Knowledge of internal hybridization barriers is relevant for germplasm conservation and utilization. The two pre-zygotic barriers are pollen–pistil self-incompatibility (SI) and cross-incompatibility (CI). To ascertain ...
Graft incompatibility in plants: Metabolic changes during formation and establishment of the rootstock/scion union with emphasis on Prunus species
(Inst Investigaciones Agropecuarias, 2015)
Commercial fruit trees are usually formed by the combination of a rootstock and a scion to broaden the adaptability
of scion cultivars to soil and climatic conditions, facilitate agricultural management, and/or increase ...
Identification of misexpressed genetic elements in hybrids between Drosophila-related species
(2017-01-16)
Crosses between close species can lead to genomic disorders, often considered to be the cause of hybrid incompatibility, one of the initial steps in the speciation process. How these incompatibilities are established and ...
Coincidence of flowering time and the productivity and quality of cauliflower hybrid seeds
(Universidade de São Paulo (USP), Escola Superior de Agricultura Luiz de Queiroz (ESALQ), 2014)
Intraspecific cross-compatibility in ornamental pepper

Incipient speciation revealed in Anastrepha fraterculus (Diptera; Tephritidae) by studies on mating compatibility, sex pheromones, hybridization, and cytology
(Wiley Blackwell Publishing, Inc, 2009-05)
It has long been proposed that the nominal species Anastrepha fraterculus is a species complex and earlier studies showed high levels of pre-zygotic isolation between two laboratory strains from Argentina and Peru. Further ...
Strong but permeable barriers to gene exchange between sister species of Epidendrum
(Botanical Soc Amer Inc, 2016-08-01)
PREMISE OF THE STUDY: The investigation of reproductive barriers between sister species can provide insights into how new lineages arise, and how species integrity is maintained in the face of interspecific gene flow. ...
