Abstract: Phegopteris decursivepinnata includes diploids, tetraploids, and triploid hybrids based on x = 30. We obtained polyploid progeny from triploid hybrids through selfing and crossing experiments. Triploids occasionally formed well-filled spores. The mean occurrence frequencies of well-filled and… read more here.

DOI: 10.1007/s11056-020-09816-z
Abstract: Woodlands in Iceland are characterized by shrub-like birch, a result of introgressive hybridization between diploid dwarf birch, Betula nana , and tetraploid downy birch, B. pubescens . Introgression occurs via triploid hybrids. We evaluated the… read more here.

Comparative transcriptome analysis of diploid and triploid hybrid groupers (Epinephelus coioides♀ × E. lanceolatus♂) reveals the mechanism of abnormal gonadal development in triploid hybrids.

DOI: 10.1016/j.ygeno.2018.11.010
Abstract: In our previous studies, diploid and triploid hybrids have been detected from the hybridization of Epinephelus coioides♀ × E. lanceolatus♂. The triploid groupers have been found to be delayed in gonadal development, but the mechanism remains poorly… read more here.

DOI: 10.3390/genes11070770
Abstract: Diploid Alnus glutinosa s. str. and autotetraploid A. rohlenae form a narrow hybrid zone in a study area in southern Serbia, which results in triploid hybrid formation. The vast majority of previous studies have been… read more here.

DOI: 10.3390/genes16010068
Abstract: Background: Interspecific hybridization between relative species Cobitis taenia (with a diploid genome designated as TT), Cobitis elongatoides (EE) and Cobitis tanaitica (NN) and the successive polyploidization with transitions from sexuality to asexuality experienced by triploid… read more here.
