Unisexual flowers as a resolution to intralocus sexual conflict in hermaphrodites. [PDF]
Proc Biol Sci, 2023 In dioecious populations, males and females may evolve different trait values to increase fitness through their respective sexual functions. Because hermaphrodites express both sexual functions, resolving sexual conflict is potentially more difficult for them. Here, we show that hermaphrodite plants can partially resolve sexual conflict by

Flower bud proteome reveals modulation of sex-biased proteins potentially associated with sex expression and modification in dioecious Coccinia grandis [PDF]
BMC Plant Biology, 2019 Background Dioecy is an important sexual system wherein, male and female flowers are borne on separate unisexual plants. Knowledge of sex-related differences can enhance our understanding in molecular and developmental processes leading to unisexual ...

Development of male and female flower in Asparagus officinalis : Search for point of transition from hermaphroditic to unisexual developmental pathway [PDF]
Sexual Plant Reproduction, 1994 Asparagus officinalis is a dioecious plant. The flowers start to develop as hermaphrodites and later become unisexual. In female flowers the stamens degenerate, while in male flowers the ovary stops growing without degenerating.

Cell cycle arrest characterizes the transition from a bisexual floral bud to a unisexual flower in Phoenix dactylifera [PDF]
Annals of Botany, 2010 International audience† Background and Aims: Phoenix dactylifera (date palm) is a dioecious species displaying strong dimorphism between pistillate and staminate flowers. The mechanisms involved in the development of unisexual flowers are as yet unknown.

The arrest of development of abortive reproductive organs in the unisexual flower of Vitis vinifera ssp. silvestris [PDF]
Sexual Plant Reproduction, 2003 During the first stages of development, flowers of most dioecious species are hermaphroditic, with their transition to unisexual flowers being the result of the developmental arrest of one set of reproductive organs.

The evolution of unisexual flowers in the Annonaceae: evidence from Pseuduvaria mulgraveana [PDF]
, 2012 The early-divergent angiosperm family Annonaceae has predominantly hermaphroditic flowers, although unisexuality has evolved in several disparate lineages. Pseuduvaria, an Asian-Pacific distributed genus with 57 species has largely unisexual flowers.

Function of male and hermaphroditic flowers and size-dependent gender diphasy of Lloydia oxycarpa (Liliaceae) from Hengduan Mountains [PDF]
Plant Diversity, 2017 Although hermaphroditism is common in flowering plants, unisexual flowers occur in many plant taxa, forming various sexual systems. However, the sexual system of some plants is difficult to determine morphologically, given that their sex expression may ...

Evolution of unisexual flowers and andromonoecy in Pseuduvaria (Annonaceae) inferred using molecular phylogenetics and pollination ecology [PDF]
, 2011 The Annonaceae is a large, early-divergent family of angiosperms consisting of c. 130 genera and 2,500 species. As with most early-divergent angiosperms, the majority of Annonaceae species have hermaphroditic, protogynous flowers. The temporal separation
