Genomic mechanisms of climate adaptation in polyploid bioenergy switchgrass
Nature, 2021 Long-term climate change and periodic environmental extremes threaten food and fuel security1 and global crop productivity2–4. Although molecular and adaptive breeding strategies can buffer the effects of climatic stress and improve crop resilience5 ...

BMC Genomics, 2022 Background An important aspect of studying evolution is to understand how new species are formed and their uniqueness is maintained. Hybridization can lead to the formation of new species through reorganization of the adaptive system and significant ...

Polyploidy breaks speciation barriers in Australian burrowing frogs Neobatrachus [PDF]
, 2020 Polyploidy has played an important role in evolution across the tree of life but it is still unclear how polyploid lineages may persist after their initial formation.

Reproduction and Breeding, 2023 The kisspeptin system, which involves hypothalamic neuropeptides, plays pivotal roles in the regulation of teleost reproduction. A previous study suggested that the kiss2/kissr2 system in largemouth bass (Micropterus salmoides) was involved in regulating

Polyploidy induction of black sesame (Sesamum indicum L.) for yield component improvement [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2021 This study was conducted with the aim of gaining the outcomes of polyploidy induction by soaking black sesame seeds, Sesamum indicum Linn, in 0.0%, 0.1%, 0.2%, 0.3% and 0.4% colchicine for 24 hours. When checking the characteristics of polyploidy using

Learning to tango with four (or more): the molecular basis of adaptation to polyploid meiosis
Plant Reproduction, 2022 Polyploidy, which arises from genome duplication, has occurred throughout the history of eukaryotes, though it is especially common in plants. The resulting increased size, heterozygosity, and complexity of the genome can be an evolutionary opportunity ...

New Phytologist, 2021 Polyploidy is a dominant feature of extant plant diversity. However, major research questions, including whether polyploidy is important to long-term evolution or is just 'evolutionary noise', remain unresolved due to difficulties associated with the ...

Quantification of ploidy in proteobacteria revealed the existence of monoploid, (mero-)oligoploid and polyploid species [PDF]
, 2011 Bacteria are generally assumed to be monoploid (haploid). This assumption is mainly based on generalization of the results obtained with the most intensely studied model bacterium, Escherichia coli (a gamma-proteobacterium), which is monoploid during ...
