Leaf transcriptome differences between diploid and tetraploid bahiagrass
The Plant Genome, Volume 19, Issue 1, March 2026.Abstract Polyploid individuals of the subtropical forage grass Paspalum notatum Flüggé (bahiagrass) exhibit distinct phenotypes, including apomixis, enhanced vigor, gigas effects, and increased stress tolerance. While apomixis‐based breeding programs supported by molecular tools have improved agronomic traits such as growth habit, forage dry matter ...

Unreduced gamete formation in plants: mechanisms and prospects [PDF]
, 2017 Polyploids, organisms with more than two sets of chromosomes, are widespread in flowering plants, including many important crop species. Increases in ploidy level are believed to arise commonly through the production of gametes that have not had their ...

Elucidating mechanisms of unreduced gamete formation in Arabidopsis thaliana
, 2022 Die Meiose ist für die sexuelle Fortpflanzung unerlässlich, und Anomalien in diesem Prozess führen oft zu Polyploidie. Während der männlichen Meiose in Arabidopsis wird das JASON (JAS)-Protein benötigt, um das „Organellenband“ aufrechtzuerhalten, das eine physikalische Barriere für zwei sich trennende Chromosomengruppen in der Metaphase II darstellt ...

Molecular Ecology, Volume 35, Issue 3, February 2026.ABSTRACT Understanding gene flow between ploidy levels in polyploid complexes is essential for species delimitation and conservation. This study explores evolutionary dynamics in the polyploid complex Thymus sect. Mastichina (Lamiaceae), comprising three taxa: T. mastichina subsp. mastichina, T. mastichina subsp.

Conservation challenges and opportunities for native apple (Malus) species in Canada
PLANTS, PEOPLE, PLANET, Volume 8, Issue 1, Page 134-156, January 2026.Apple, one of the world's most widely cultivated and economically important fruit crops, has two wild relatives native to Canada. In this review, we describe the importance of these native apple species to Indigenous heritage and the current threats the species faces due to pests, diseases, and habitat loss.

Plant Species Biology, Volume 41, Issue 1, January 2026.Upon prolonged waterlogging, a Costus speciosus plant developed bulbils at stem node. Karyotype analysis, nucleolar staining, and anatomical study revealed its triploid status and developmental aspects. Prevalence of tetraploid, abundance, and unique reproductive fecundity of the triploid, indicates its determinant role in coexistence of the multiple ...

Analysis of variation for apomictic reproduction in diploid Paspalum rufum [PDF]
, 2014 Background and Aims: The diploid cytotype of Paspalum rufum (Poaceae) reproduces sexually and is self-sterile; however, recurrent autopolyploidization through 2n + n fertilization and the ability for reproduction via apomixis have been documented in one ...

Abnormal chromosome behavior during meiosis in the allotetraploid of Carassius auratus red var. (♀) × Megalobrama amblycephala(♂) [PDF]
, 2014 BACKGROUND: Allopolyploids generally undergo bivalent pairing at meiosis because only homologous chromosomes pair up. On the other hand, several studies have documented abnormal chromosome behavior during mitosis and meiosis in allopolyploids plants ...
