Prickly Problems: Cylindropuntia's Low Genetic Diversity Despite Inbreeding Avoidance [PDF]
Ecology and EvolutionDioecy, the separation of sexes, is found in 6% of flowering plants. One widely known hypothesis suggests that it is an adaptation to mitigate inbreeding. A contrary hypothesis suggests that dioecy is an evolutionary dead end.

A Foundational Population Genetics Investigation of the Sexual Systems of Solanum (Solanaceae) in the Australian Monsoon Tropics Suggests Dioecious Taxa May Benefit from Increased Genetic Admixture via Obligate Outcrossing [PDF]
Plants, 2023 Solanum section Leptostemonum is an ideal lineage to test the theoretical framework regarding proposed evolutionary benefits of outcrossing sexual systems in comparison to cosexuality.

Frontiers in Plant Science, 2022 Sex determination in dioecious plants has been broadly and progressively studied with the blooming of genome sequencing and editing techniques. This provides us with a great opportunity to explore the evolution and genetic mechanisms underlining the sex ...

Rodriguésia, 2022 Several possible correlations between dioecy and eco-morphological features have been suggested to infer the conditions that would favor this sexual system. Dioecy has been associated either with specialized or generalized pollination systems.

Phylogenetic Analysis of Dioecy in Monocotyledons [PDF]
The American Naturalist, 2000 Surveys of plant breeding systems in angiosperm families have shown a significant association between monoecy and dioecy, and researchers have proposed that dioecy has tended to evolve from monoecy. We evaluated this hypothesis in the context of a phylogeny of 918 monocotyledons assembled from 19 published trees.

The Diversity and Dynamics of Sex Determination in Dioecious Plants
Frontiers in Plant Science, 2021 The diversity of inflorescences among flowering plants is captivating. Such charm is not only due to the variety of sizes, shapes, colors, and flowers displayed, but also to the range of reproductive systems. For instance, hermaphrodites occur abundantly

Plants, 2022 The vegetative and reproductive growth of plants provide the basic tempo for an ecosystem, and when species are interdependent, phenology becomes crucial to regulating the quantity and quality of the interactions. In plant–insect interactions, the plants

Functional Dioecy and Andromonoecy in Solanum [PDF]
Evolution, 1989 Field and laboratory studies of 19 diclinous species endemic to Australia help to clarify the nature and evolution of andromonoecy, androdioecy, and dioecy in the genus Solanum. Ten species are andromonoecious; typically these species bear inflorescences with a single, large basal hermaphroditic flower and 12-60 distal, smaller staminate flowers.

Revision of Tinospora (Menispermaceae - Chasmantheroideae - Burasaieae) in Singapore
European Journal of Taxonomy, 2023 The lianescent genus Tinospora Miers in Singapore is revised. Four species are recognised, two of which are newly described. Tinospora krispura I.M.Turner sp. nov. is known from Christmas Island and Singapore. Tinospora singapura I.M.Turner sp. nov.
