Journal of Systematics and Evolution, EarlyView.Using Angiosperms353 and plastid genome skimming approaches, the generic limits of Hyacinthinae were explored using DNA sequences to better understand their evolution. Floral morphology, a traditional generic delimiter, conflicts with the molecular groupings in many cases, but bulb morphology and cytogenetics define similar groups to DNA.

Biological ControlParasitoid wasps are haplodiploid insects, but polyploidy (diploid males, triploid females) occurs for many species. In biological control, polyploidy may have beneficial effects on desirable biological related traits.

Karyotype analysis in 19 families from the Qinghai–Tibetan Plateau and its evolution implications
Caryologia, 2022 The chromosome numbers and karyotypes of 79 species and accessions from 19 plant families growing on the Qinghai–Tibetan Plateau were investigated. For 31 species, we provided first insights into their chromosomal numbers and karyotypic characteristics ...

Plant Biotechnology Journal, EarlyView.ABSTRACT Sugar crops, including but not limited to sugarcane, sugar beet, sweet sorghum and stevia, are major sources of sugar production in the world. However, conventional breeding approaches, limited by long breeding cycles, low efficiency and restricted capacity to improve complex traits in sugar crops, are increasingly insufficient to address the ...

On the quest to study polyploidy in cyanobacteria [PDF]
This thesis investigates the nuanced interplay between polyploidy and evolvability in prokaryotes, with a focus on Synechocystis PCC 6803. Traditionally thought to be rare in prokaryotes, polyploidy has been identified across diverse bacterial and ...

Musa interspecific hybridization and polyploidy for breeding banana and plantain (Musaceae)
, 2016 Banana and plantain (Musa spp.) are perennial, giant herbs grown mostly in small plots and orchards. The main centers of Musa diversity are in the tropics: from South Asia to Polynesia. All edible cultivars derived from the diploid species M.

Breaking down taxonomic barriers in polyploidy research
, 2003 Polyploidy is important in the evolutionary history of plants, and it has played a crucial role in shaping the genome structures of all eukaryotes. New and rapidly improving techniques in genomics, cytogenetics and molecular ecology have resulted in a ...

Plant Biotechnology Journal, EarlyView.ABSTRACT Polyploidisation, creating redundant or diverged copies of the genome, is a major driving force in plant evolution, diversification and environmental adaptation, including for the kiwifruit genus (Actinidia Lindl.). We present a high‐contiguity, haplotype‐resolved genome assembly of the hexaploid Actinidia valvata rootstock cultivar ...

Journal of Experimental Biology, 1924 ABSTRACT By polyploidy is meant an increase in the number of sets of chromosomes in a plant or animal. The bodies of animals and of the higher plants normally contain two sets of chromosomes, one derived from each parent. In ordinary sexual reproduction this number is reduced to one half in the maturation of the germ cells, and the ...
