Parasexual Interspecific Plant Hybridization [PDF]
Proceedings of the National Academy of Sciences, 1972 Interspecific plant hybrids have been produced by parasexual procedures. Protoplasts of Nicotiana glauca and N. langsdorffii were isolated, fused, and induced to regenerate into plants. The somatic hybrids were recovered from a mixed population of parental and fused protoplasts by a selective

Recombining your way out of trouble: the genetic architecture of hybrid fitness under environmental stress [PDF]
, 2020 Hybridization between species is a fundamental evolutionary force that can both promote and delay adaptation. There is a deficit in our understanding of the genetic basis of hybrid fitness, especially in non-domesticated organisms.

Editorial: Interspecific hybridization in plant biology
Frontiers in Plant Science, 2022 Many crop gene pools are derived from small numbers of founders. As a consequence of long histories of strong directional selection, crop gene pools have narrow genetic diversity available to provide inherent solutions to changing needs or challenges.

Spore-autonomous fluorescent protein expression identifies meiotic chromosome mis-segregation as the principal cause of hybrid sterility in yeast. [PDF]
PLoS Biology, 2018 Genome-wide sequence divergence between populations can cause hybrid sterility through the action of the anti-recombination system, which rejects crossover repair of double strand breaks between nonidentical sequences. Because crossovers are necessary to

Ploidy level and molecular phylogenic relationship among novel Ipomoea interspecific hybrids
Czech Journal of Genetics and Plant Breeding, 2014 Interspecific hybridization can be used to broaden the genetic base, generate novel species, postulate genetic relationships, and to introgress elite alien genes.

Introgression in interspecific hybrids of lily [PDF]
, 2002 In order to introduce new desirable characters into the cultivar assortment of lily a range of interspecific crossing barriers has to be overcome. By using various pollination and embryo rescue techniques pre- and postfertilization barriers were overcome

Epigenetic consequences of interploidal hybridisation in synthetic and natural interspecific potato hybrids [PDF]
, 2019 Interploidal hybridisation can generate changes in plant chromosome numbers, which might exert effects additional to the expected due to genome merger per se (i.e., genetic, epigenetic and phenotypic novelties).Wild potatoes are suitable to address this ...

Interspecific Hybridization among Mycobacteria [PDF]
Nature, 1960 EXPERIMENTS conducted in the first part of this work showed that a high degree of streptomycin resistance can be transmitted to M. phlei when a streptomycin-sensitive strain of this micro-organism and a streptomycin-resistant BCG strain of M. tuberculosis are cultured together in ‘Tween’ liquid medium.

Identifying hybridizing taxa within the Daphnia longispina species complex: a comparison of genetic methods and phenotypic approaches [PDF]
, 2010 Daphnia galeata Sars, D. longispina O. F. Muller and D. cucullata Sars (Crustacea: Cladocera) are closely related species which often produce interspecific hybrids in natural populations.
