Is increased male flower production a strategy for avoidance of predispersal seed predation in andromonoecious plants?

open access: yesEcology and Evolution, 2021
Floral gender in angiosperms often varies within and among populations. We conducted a field survey to test how predispersal seed predation affects sex allocation in an andromonoecious alpine herb Peucedanum multivittatum.

Seasonal change of flower sex ratio and pollinator dynamics in three reproductive ecotypes of protandrous plant

open access: yesEcosphere, 2020
Cimicifuga simplex has three genetically and ecologically distinct pollination morphs with different flowering phenology, flower sex expressions, and selfing rates. A previous study showed that strong protandry in hermaphroditic flowers of C.

Phytohormone and integrated mRNA and miRNA transcriptome analyses and differentiation of male between hermaphroditic floral buds of andromonoecious Diospyros kaki Thunb [PDF]

open access: yesBMC Genomics, 2021
Background Persimmon (Diospyros kaki Thunb.) has various labile sex types, and studying its sex differentiation can improve breeding efficiency. However, studies on sexual regulation patterns in persimmon have focused mainly on monoecy and dioecy ...

Andromonoecy and developmental plasticity in Chaerophyllum bulbosum (Apiaceae-Apioideae). [PDF]

open access: yesAnn Bot, 2013
Andromonoecy, the presence of hermaphrodite and male flowers in the same individual, is genetically fixed or induced, e.g. by fruit set. Little is known about the forces triggering andromonoecy in the Apiaceae. In the present study, a natural population of the protandrous Chaerophyllum bulbosum was investigated to elucidate architectural constraints ...

The Ethylene Biosynthesis Gene CitACS4 Regulates Monoecy/Andromonoecy in Watermelon (Citrullus lanatus). [PDF]

open access: yesPLoS ONE, 2016
Monoecious and andromonoecious cultivars of watermelon are characterised by the production of male and female flower or male and hermaphrodite flowers, respectively.

Evidence of andromonoecy in a northern population of Guaiacum coulteri (Zygophyllaceae).

open access: yesBotan‪ical Sciences
Background: Angiosperms exhibit diverse reproductive systems, and andromonoecy—where individuals produce both hermaphroditic and staminate flowers—is rare, occurring in about 1.7 % of species.

Andromonoecy and buzz pollination in Solanum species (Solanaceae) endemic to the Canary Islands

open access: yesAnales del Jardín Botánico de Madrid, 2006
We investigated the pollination and reproductive biology of two Canary Island endemics, Solanum vespertilio and S. lidii (Solanaceae). We measured male function (pollen development), female function (fruit initiation) and spatial arrangement of ...

Disruptive selection via pollinators and seed predators on the height of flowers on a wind-dispersed alpine herb. [PDF]

open access: yesAm J Bot, 2022
Abstract Premise Floral stalk height is known to affect seed dispersal of wind‐dispersed grassland species, but it may also affect the attractiveness of flowers and fruits of animal‐pollinated and animal‐dispersed plants. Stalk height may thus be responsive to selection via interactions with both mutualist pollinators and seed dispersers, but also ...

Separated Sexes, Shared Consequences: Disentangling Predictors of Genetic Diversity in Dioecious Angiosperms. [PDF]

open access: yesEcol Evol
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 ...

Reversibility of sex changes in the plant kingdom: more important than we thought? [PDF]

open access: yesBiol Rev Camb Philos Soc
ABSTRACT Compared to animals, plants show a wide range of reproductive strategies with different degrees of sex separation (e.g. dioecy, monoecy, hermaphroditism). While sex expression was previously thought to be genetically determined and fixed in plants, accumulating evidence suggests that sex expression can change reversibly even within one ...
