Pappea capensis: monoecious, dioecious or androdioecious?
South African Journal of Botany, 1993 Pappea capensis used to be regarded a dioecious plant. In this short communication, evidence is provided which shows that Pappea capensis is monoecious with a distinct male phase followed by a distinct female phase.

Ecology and Evolution, Volume 16, Issue 5, May 2026.This study evaluates the factors influencing intrapopulation genetic diversity in dioecious flowering plants by integrating genetic and ecological data from studies published up to 2025. We show that pollination mode, endemism, and conservation status significantly shape genetic diversity patterns, with endemic and threatened species exhibiting the ...

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 ...

Characteristics of Sex Expression in Monoecious Persimmons.
Engei Gakkai zasshi, 1992 A persimmon (Diospyros kaki) tree may manifest three types of flowers; female, male, and perfect (hermaphrodite). Most cultivars bear only female flowers but others have both female and male and sometimes perfect flowers as well. In monoecious or polygamous cultivars, sex expression has been observed to be modified by the previous year's fruit load and

The Red Queen unveils the sexual and mating strategies of flowers
Journal of Ecology, Volume 114, Issue 5, May 2026.Although the conventional wisdom is that floral traits of plants evolved in concert with their mutualistic pollinators, here we showed that several key sexual and mating traits of plants, which modulate their outcrossing strategy, evolved in response to the pressure exerted by their antagonistic insect herbivores.

Rate of Natural Outcrossing in Monoecious Cucumbers
HortScience, 1985 Abstract The rate of natural outcrossing in cucumber ( Cucumis sativus L.) was measured at 3 locations in North Carolina, using the dominant allele for scab resistance as the marker gene. Outcrossing was measured within and between 1.5 m plots in isolation blocks.

Sex‐specific ethylene responses drive floral sexual plasticity in Cannabis sativa
The Plant Journal, Volume 125, Issue 3, February 2026.SUMMARY Cannabis sativa L. exhibits pronounced sexual plasticity in which both XX and XY plants can undergo floral phenotypic sex reversal in response to ethylene modulation, yet the underlying molecular mechanisms remain poorly defined. Here, we present the most extensive multi‐omic analysis of ethylene‐induced sex change in C.

Toward an art of genomic selection in vegetable breeding
Crop Science, Volume 66, Issue 1, January/February 2026.Abstract Genomic selection (GS) is a powerful strategy for accelerating genetic gain in plant breeding. While in recent years GS has been widely adopted in breeding programs for agronomic crops, its implementation in vegetable breeding has been comparatively limited.
