Unisexual flowers as a robust synapomorphy in Cariceae (Cyperaceae)? Evidence for bisexual flowers in Schoenoxiphium [PDF]
South African Journal of Botany, 2012 Cariceae, the largest tribe within Cyperaceae, comprises about 2000 species in five genera. Cariceae is usually considered to be distinct from other Cyperaceae by the presence of exclusively unisexual flowers and by the arrangement of the pistillate ...

A cucurbit androecy gene reveals how unisexual flowers develop and dioecy emerges [PDF]
Science, 2015 International audienceUnderstanding the evolution of sex determination in plants requires identifying the mechanisms underlying the transition from monoecious plants, where male and female flowers coexist, to unisexual individuals found in dioecious ...

Bird–nest puzzle: can the study of unisexual flowers such as cucumber solve the problem of plant sex determination? [PDF]
Protoplasma, 2012 Unisexual flower development has long been used as a model system to understand the mechanism of plant sex determination. However, based on our investigation of the mechanisms regulating the development of unisexual cucumber flowers, we have realized ...

Pathways for making unisexual flowers and unisexual plants:Moving beyond the “two mutations linked on one chromosome” model [PDF]
American Journal of Botany, 2016 Sex determination in higher plants is of fundamental biological interest and has great practical significance for fruit yield and high-quality seed production. Th e last decades have witnessed an explosion in the genetic-developmental understanding of a typical hermaphroditic flower; however, the genes controlling dicliny (unisexual fl owers) and ...

ARE UNISEXUAL FLOWERS PRIMITIVE? [PDF]
New Phytologist, 1986 SummarySporne's statistical evaluation of primitiveness in angiosperms has generated a good deal of controversy, mainly because his identification of unisexual flowers as primitive is at variance with most other interpretations of angiosperm evolution.

Unisexual Cucumber Flowers, Sex and Sex Differentiation
International Review of Cell and Molecular Biology, 2013Sex is a universal phenomenon in the world of eukaryotes. Attempts have been made to understand regulatory mechanisms for plant sex determination by investigating unisexual flowers. The cucumber plant is one of the model systems for studying how sex determination is regulated by phytohormones.

The evolution of unisexual flowers: morphological and functional convergence results from diverse developmental transitions [PDF]
American Journal of Botany, 2005 Unisexual flower morphology was examined within a phylogenetic context in order to identify developmental transitions associated with the multiple origins of dioecy in flowering plants. Historically, two categories of unisexual flowers have been recognized: type I flowers exhibit rudiments of the nonfunctional organ type, while type II flowers bear no ...

Unisexual Flowers in the Ericales
Nature, 1957THE flowers of the Epacridaceae have been described as hermaphrodite1,2 or hermaphrodite, rarely dioecious3, but in the latter case no examples of dioecy are quoted. The following notes concerning species previously described as hermaphrodite indicate that unisexual flowers may be not uncommon in this family.

Differential Floral Rewards and Pollination by Deceit in Unisexual Flowers
Oikos, 1989Male and female unisexual flowers often offer different levels of rewards for pollinators and in some species pollination is apparently based on deception. A review of the literature indicates that male flowers commonly offer more reward than female, although when the reward is nectar, female flowers sometimes offer more than male.
