Molecular Reproduction and Development, Volume 93, Issue 6, June 2026.ABSTRACT Sex determination in Porifera remains one of the least understood aspects of early metazoan biology despite the group's key phylogenetic position. Sponges display exceptional diversity in sexual systems—ranging from stable gonochorism to sequential hermaphroditism and sex reversal—yet lack morphological dimorphism and any discrete gonadal ...

Repeated Evolution of Dioecy from Monoecy in Siparunaceae (Laurales) [PDF]
, 2001 Siparunaceae comprise Glossocalyx with one species in West Africa and Siparuna with 65 species in the neotropics; all have unisexual flowers, and 15 species are monoecious, 50 dioecious.

PlantsSexual dimorphism in dioecious plants serves as a critical adaptive strategy in complex environments. This study systematically investigated the effects of topographic factors (elevation, slope, aspect, and convexity), soil nutrients (C, N, P), and ...

Differentiation during fig ontogeny suggests opposing selection by mutualists
Ecology and Evolution, 2020 Dioecy allows separation of female and male functions and therefore facilitates separate co‐evolutionary pathways with pollinators and seed dispersers. In monoecious figs, pollinators' offspring develop inside the syconium by consuming some of the seeds.

Can Herbivore Feeding Preferences Reinforce the Female‐Biased Sex Ratio in an Alpine Willow? [PDF]
Ecol EvolSex‐biased herbivory can vary among co‐occurring herbivores and across the season. Sequential herbivory by species with different feeding preferences may influence the population dynamics of dioecious plants, particularly if early‐season herbivory alters plant traits that affect subsequent foraging decisions.

Pleiotropic effects of sex-determining genes in the evolution of dioecy in two plant species
Proceedings of the Royal Society B, 2019 One reason for studying sex chromosomes of flowering plants is that they have often evolved separate sexes recently, and the genomes of dioecious species may not yet have evolved adaptations to their changes from the ancestral state.

Genetic architecture of phenological, morphological, and phytochemical traits in Cannabis landraces
The Plant Genome, Volume 19, Issue 2, June 2026.Abstract Despite its long history of cultivation and diverse applications, Cannabis sativa remains underexplored at the genomic level, particularly in landrace populations that harbor untapped genetic diversity. In this study, we investigated the genetic architecture of 145 Iranian cannabis landrace accessions, including both male and female plants ...

Genetic insights into the dissolution of dioecy in diploid persimmon Diospyros oleifera Cheng [PDF]
, 2023 BACKGROUND: Dioecy, a sexual system of single-sexual (gynoecious/androecious) individuals, is rare in flowering plants. This rarity may be a result of the frequent transition from dioecy into systems with co-sexual individuals. RESULTS: In this study, co-

Phylogenetic origins of dioecy in Silene
, 2005 The aim of this project is to provide a phylogenetic/taxonomic framework for the evolution of dioecy within Silene (Caryophyllaceae). There are several dioecious taxa within the genus, traditionally classified in the sections Elisanthe and Otites.
