Evolution of plant sex and molecular mechanisms underlying plants sex separation
Forestry Research, 2023 Unlike animals, plants exhibit more complexity of sexual morphs. The genetic mechanism underlying plant sex is a hot research topic in plant biology. In recent decades, advanced theories have been put forth on plant sex determination, but experimental ...

The ecology, evolution, and biogeography of dioecy in the genus Solanum: With paradigms from the strong dioecy in Solanum polygamum, to the unsuspected and cryptic dioecy in Solanum conocarpum [PDF]
American Journal of Botany, 2015 • Premise of the study: Island plants are over‐exploited and “under‐explored.” Understanding the reproductive biology of plants, especially rare species, is fundamental to clarifying their evolution, estimating potential for change, and for creating effective conservation plans. Clarification of sexual systems like dioecy, and unusual manifestations of

Data from: Recurrent evolution of dioecy in bryophytes
, 2012 The origin and maintenance of separate sexes (dioecy) is an enduring evolutionary puzzle. Although both hermaphroditism and dioecy occur in many diverse clades, we know little about the long-term evolutionary consequences of changing sexual system.

Sex expression in Serbian dendroflora: A case study of Fraxinus ornus var. angustifolia [PDF]
Archives of Biological Sciences, 2012 Out of a total number of tree species in Serbian flora, 28% are hermaphrodites, 43% are monoecious and 29% are dioecious. The dendroflora appears to have a larger proportion of unisexual than hermaphrodite species.

Sex Allocation: Evolution to and from Dioecy [PDF]
Current Biology, 2009 Sex allocation in hermaphrodites should evolve in response to changes in the frequency of unisexuals. As predicted, it has now been demonstrated that hermaphrodites respond to the removal of males from experimental plant populations by increasing their allocation to male function.

Dioecy is associated with higher diversification rates in flowering plants
, 2014 International audienceIn angiosperms, dioecious clades tend to have fewer species than their nondioecious sister clades. This departure from the expected equal species richness in the standard sister clade test has been interpreted as implying that ...

Frontiers in Plant Science, 2019 Dioecy, the specialization of individuals into either male-only or female-only sexual function, has multiple evolutionary origins in plants. One proposed ancestral mating system is heterodichogamy, two morphs of cross-fertilizing hermaphrodite flowers ...

Repeated Evolution of Dioecy from Monoecy in Siparunaceae (Laurales) [PDF]
, 2001 Siparunaceae comprise Glossocalyx with one species in West Africa and Siparuna with 65 species in the neotropics; all have unisexual flowers, and 15 species are monoecious, 50 dioecious.

Thermogenesis‐derived spatiotemporal microclimates guide pollinator movement to ensure pollination
Journal of Integrative Plant Biology, EarlyView.Alocasia odora's microclimatic heterogeneity guides Colocasiomyia fly movement within its inflorescence. During the female stage, midday heat in the upper spadix pushes flies down to the cooler female zone. During the male stage, nocturnal warmth in the upper part pulls flies upward and spathe constriction closes the lower female chamber.
