Genomics of sex determination in dioecious trees and woody plants [PDF]
, 2017 Dioecious plant species are characterized by unisexual flowers located on separate male or female individuals. While only about 5–6% of angiosperm species are reported to be dioecious, tree species seem to show a higher percentage of dioecy.

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.

Black Truffle, a Hermaphrodite with Forced Unisexual Behaviour [PDF]
Trends in Microbiology, 2017 The life cycle of the black truffle (Tuber melanosporum) includes a mating before sporulation: although the species is hermaphroditic, mating turns out to involve parents with very different features, that mostly behave as male or female only, suggesting that this species undergoes forced dioecism.

Nature CommunicationsIn flowering plants, the predominant sexual morph is hermaphroditism, and the emergence of unisexuality is poorly understood. Using Cucumis melo (melon) as a model system, we explore the mechanisms driving sexual forms.

The genetic basis of unisexuality in Isotoma fluviatilis [PDF]
, 1969 I.fluviatilis occurs in diploid hermaphrodite, tetraploid hermaphrodite, and diploid dioecious populations. Studies of seed production and germination showed significant but incomplete genetic barriers between the various sex and ploid forms.

Analysis of the meiotic segregation in intergeneric hybrids of tilapias [PDF]
, 2012 Tilapia species exhibit a large ecological diversity and an important propensity to interspecific hybridisation. This has been shown in the wild and used in aquaculture.

A comparative study on the functional response of Wolbachia-infected and uninfected forms of the parasitoid wasp Trichogramma brassicae [PDF]
, 2010 Trichogramma species (Hymenoptera: Trichogrammatidae) are haplo-diploid egg parasitoids that are frequently used as biological control agents against lepidopteran pests.

Floral mutants in tomato: development, physiology, and evolutionary implications [PDF]
, 1992 Developmental and experimental studies on two floral mutants of tomato (Lycopersicon esculentum) are presented. These studies have provided insights into the gene-regulated physiological, biochemical, and structural processes that affect flower ...

The Conservation of Unisexual Vertebrate Populations [PDF]
Conservation Biology, 1995 Ranker and Arft (1994) brought needed attention to current ambiguity in the use of the term "hybrid" and the potential confusion this ambiguity can have on the protection of allopolyploid plants under the U.S. Endangered Species Act (ESA). This legislation denies protection to hybrids under the (not explicitly stated) rationale that "hybrids" as ...
