The quest for molecular regulation underlying unisexual flower development
Frontiers in Plant Science, 2016 The understanding of the molecular mechanisms responsible for the making of a unisexual flower has been a long-standing quest in plant biology. Plants with male and female flowers can be divided mainly into two categories: dioecious and monoecious, and ...

Unisexual reproduction in Huntiella moniliformis [PDF]
Fungal Genetics and Biology, 2015 Sexual reproduction in fungi is controlled by genes present at the mating type (MAT) locus, which typically harbors transcription factors that influence the expression of many sex-related genes. The MAT locus exists as two alternative idiomorphs in ascomycetous fungi and sexual reproduction is initiated when genes from both idiomorphs are expressed ...

Cytogenetic mechanisms of unisexuality in rock lizards [PDF]
Scientific Reports, 2020 AbstractDarevskia rock lizards is a unique complex taxa, including more than thirty species, seven of which are parthenogenetic. In mixed populations of Darevskia lizards, tri- and tetraploid forms can be found. The most important issues in the theory of reticulate evolution of Darevskia lizards are the origin of parthenogenetic species and their ...

Functional monoecy due to delayed anther dehiscence: a novel mechanism in Pseuduvaria mulgraveana (Annonaceae). [PDF]
PLoS ONE, 2013 Unlike most genera in the early-divergent angiosperm family Annonaceae, Pseuduvaria exhibits a diversity of floral sex expression. Most species are structurally andromonoecious (or possibly androdioecious), although the hermaphroditic flowers have been ...

Data from: On the possible role of nonreproductive traits for the evolution of unisexuality: life‐history variation among males, females, and hermaphrodites in Opuntia robusta (Cactaceae) [PDF]
, 2018 In angiosperms, dioecy has arisen in 871–5,000 independent events, distributed in approximately 43% of the flowering families. The reproductive superiority of unisexuals has been the favorite explanation for the evolution of separate sexes.

Phylogenic points of view on the sexuality of cormophytes
Acta Societatis Botanicorum Poloniae, 2014 1) Unisexuality is spreading from gametes, through gametophytes, to sporangia and sporaphytes, individual hermaphradite plants finally becoming the ground for sex separation with cross fertilization processes; 2) male and female gametogeneses are ...

A conserved ethylene biosynthesis enzyme leads to andromonoecy in two cucumis species. [PDF]
PLoS ONE, 2009 Andromonoecy is a widespread sexual system in angiosperms, characterized by plants carrying both male and bisexual flowers. Monoecy is characterized by the presence of both male and female flowers on the same plant.
