Testing mechanisms of compensatory fitness of dioecy in a cosexual world [PDF]

open access: yes, 2019
Questions: All else being equal, populations of dioecious species with a 50:50 sex ratio have only half the effective reproductive population size of bisexual species of equal abundance. Consequently, there is a need to explain how dioecious and bisexual

Pappea capensis: monoecious, dioecious or androdioecious?

open access: yesSouth 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.

Analysis of sexual phenotype and prezygotic fertility in natural populations of Fucus spiralis, F. vesiculosus (Fucaceae, Phaeophyceae) and their putative hybrids [PDF]

open access: yes, 2014
In the genus Fucus, the character dioecy/hermaphroditism has undergone multiple state changes and hybridization is possible between taxa with contrasting mating systems, e.g. between the dioecious Fucus vesiculosus and the hermaphrodite F. spiralis.

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

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 ...

Starmaya: The first arabica F1 coffee hybrid produced using genetic male sterility [PDF]

open access: yes, 2019
In the present paper, we evaluated the implementation of a seed production system based on the exploitation of male sterility on coffee. We studied specifically the combination between CIR-SM01 and Marsellesa® (a Sarchimor line), which provides a hybrid ...

Molecular Mechanism Underlying Derepressed Male Production in Hexaploid Persimmon

open access: yesFrontiers in Plant Science, 2020
Sex expression in plants is often flexible and contributes to the maintenance of genetic diversity within a species. In diploid persimmons (the genus Diospyros), the sexuality is controlled by the Y chromosome-encoded small-RNA gene, OGI, and its ...
