Plant Breeding, EarlyView.ABSTRACT The combination of polyploidy, apomixis and the formation of aneuploid and interploid hybrids makes the genus Urochloa an interesting system for investigating meiotic stability and genome behaviour in grasses. In this study, routine meiotic analysis and genomic in situ hybridization (GISH) were used to (i) evaluate meiosis in three hybrids of ...

Environmental and Evolutionary Correlates of Extinction Risk in a Global Biodiversity Hotspot
Ecology and Evolution, Volume 16, Issue 9, September 2026.We show that larger genera have a greater number of threatened and near‐threatened species, and that extinction risk is uncoupled with evolutionary history (diversification, speciation, extinction rates and lineage age). The decoupling of diversification rates and lineage age with current extinction risk suggests drivers of extinction risk are ...

An Apomixis-Gene’s View on Dandelions
, 2009 In asexual organisms, the clone constitutes a level above the individual. Most dandelions (Taraxacum officinale s.l.) reproduce asexually through apomixis, asexual reproduction through seeds.

New Zealand Journal of Zoology, Volume 53, Issue 3, September 2026.In arthropods, thelytokous parthenogenesis, in which females develop from unfertilised eggs, is often associated with reproductive manipulation by endosymbiotic bacteria such as Wolbachia and Cardinium. This study investigated whether thelytokous parthenogenesis in two mite species, Amblyseius herbicolus (Phytoseiidae) and Czenspinskia ...
