The M Locus and Ethylene-Controlled Sex Determination in Andromonoecious Cucumber Plants [PDF]
Plant and Cell Physiology, 2001 Sex determination in cucumber (Cucumis sativus L.) plants is genetically controlled by the F and M loci. These loci interact to produce three different sexual phenotypes: gynoecious (M-F-), monoecious (M-ff), and andromonoecious (mmff). Gynoecious cucumber plants produce more ethylene than do monoecious plants.

Selection through female fitness helps to explain the maintenance of male flowers [PDF]
, 2007 Andromonoecy, the production of both male and hermaphrodite flowers in the same individual, is a widespread phenomenon that occurs in approximately 4,000 species distributed in 33 families.

Sexual Dimorphism and Gynoecium Size Variation in the Andromonoecious Shrub Caesalpinia gilliesii
Plant Biology, 2005 Abstract: The degree of sexual dimorphism in flowers and inflorescences can be evaluated early in flower development through the study of floral organ size co‐variation. In the present work, the gynoecium‐androecium size relationship was studied to assess the degree of sexual expression in flowers and inflorescences of the andromonoecious shrub ...

The effect of flower position on variation and covariation in floral traits in a wild hermaphrodite plant [PDF]
, 2010 Background Floral traits within plants can vary with flower position or flowering time. Within an inflorescence, sexual allocation of early produced basal flowers is often female-biased while later produced distal flowers are male-biased.

Ecology and Evolution, Volume 16, Issue 4, April 2026.ABSTRACT The genus Globba (Zingiberaceae) comprises over 100 species distributed worldwide, with a primary concentration in Southeast Asia. These plants are of significant interest due to their distinctive and delicate floral morphology as well as their potential medicinal value.

The evolution of unisexual flowers in the Annonaceae: evidence from Pseuduvaria mulgraveana [PDF]
, 2012 Insect-Plant evolutionary ecology (Session I)The early-divergent angiosperm family Annonaceae has predominantly hermaphroditic flowers, although unisexuality has evolved in several disparate lineages.

Journal of Ecology, Volume 113, Issue 10, Page 2832-2845, October 2025.Spatiotemporal variation in seed predation can act as a selective force on floral gender. The floral sex allocation of an alpine andromonoecious herb varied among local populations. Early‐flowering populations suffered from intensive seed predation by moth larvae, where male‐biased sex allocation was advantageous in reducing the risk of oviposition. In

Frontiers in Ecology and EvolutionIntroductionThe carrot family (Apiaceae) is characterized by umbels with umbellets. Traditionally, these umbels are interpreted as inflorescences. Ontogenetic studies, however, indicate that they do not originate from inflorescence meristems but from ...
