Sex determination in gymnosperms
TLDR
The multiple origins of dioecy is evident by its presence in evolutionarily distinct taxa, which provides an opportunity to explore diverse types and their mechanisms of sex determination in this group of plants.
The Diversity and Dynamics of Sex Determination in Dioecious Plants
TLDR
A unified model is presented that synthesizes the genetic networks of sex determination in monoecious and dioecious plants and will support the generation of hypothesis regarding candidate sex determinants in future studies.
Sexual System and Ecological Links of Flowering Plants in Changbai Mountain
TLDR
The monoecious and dioecious plants always had dry fruit and the hermaphroditism had fleshy fruit, and the plant sexual system was also correlated with plant fruit types.
Evidence for a double mutualistic interaction between a lizard and a Mediterranean gymnosperm, Ephedra fragilis
TLDR
The importance of a lizard species in one of the few double mutualisms found in the World involving a gymnosperm is reported, and it represents the first documentation of a double mutualism in the Mediterranean region.
Differences and similarities of sex ratios between dioecious angiosperms and dioicous bryophytes
TLDR
Primary sex ratios were often variable, suggesting genomic conflict involving both cytoplasmic factors and sex-linked drive, and even though theory predicts some differences, primary sex ratios of angiosperms and bryophytes were remarkably similar.
Defence Is a Priority in Female Juveniles and Adults of Taxus baccata L.
TLDR
Female individuals of dioecious plants invest their resources more in storage and defence, and the males have higher nitrogen content invested in the production of pollen grains, suggesting that defence is a priority for females from an early age.
Evolution of the sex-determining region in Ginkgo biloba
TLDR
The Ginkgo SDR is fairly old—at least of Cretaceous origin—and evolves in a region with pre-existing reduced recombination, surrounded by long actively recombining pseudoautosomal regions, consistent with findings in other dioecious plants with homomorphic sex chromosomes.
Dioecy in Flowering Plants: From the First Observations of Prospero Alpini in the XVI Century to the Most Recent Advances in the Genomics Era
TLDR
The two main models explaining dioecism are illustrated by taking a cue from two plant species, grapevine and poplar, in which genomics and single molecule sequencing technologies played a pivotal role in scientific advance in this field.
Gender plasticity uncovers multiple sexual morphs in natural populations of Cedrus deodara (Roxb.) G. Don
TLDR
The results of the study suggest that the subdioecious gender expression in C. deodara is evolved through the monoecy–paradioecy pathway, and the size of the tree, resource availability, sex allocation, plant architecture, gender segregation in crowns, and habitat conditions are the prominent causes for gender plasticity.
IDENTIFICATION OF SEX IN ZAMIA INERMIS USING ISSR MARKERS
Zamia inermis is a dioecious cycad endemic to the State of Veracruz that is on the risk extinction. Sexspecific markers are important in understanding the mechanism of sex determination. However,

Dioecy and its correlates in the flowering plants
TLDR
Dioecy appears to have evolved most frequently via monoecy, perhaps through divergent adjustments of floral sex ratios between individual plants, as revealed by multivariate analysis.
Lower Species Richness in Dioecious Clades

TLDR
It is suggested that Baker’s law is not the reason for the poor representation of dioecy among angiosperm species, and self‐compatible lineages may have higher rates of allopatric speciation than hermaphroditic self‐incompatible angiosperms.

TLDR
Dioecious focal lineages with a higher number of ecological traits experienced higher evolutionary success in sister-group comparisons, whereas no trend was found for the control focal lineage.
Sexual stability in the nearly dioecious Pinus johannis (Pinaceae).
TLDR
The variety of sexual morphs coexisting in the same population makes P. johannis a model for studying the evolution of dioecy in gymnosperms and represents the first report of a nearly stabledioecious Pinus species.
Evolution of Dioecy in Flowering Plants
TLDR
It is argued that dioecy is not as rare as is generally assumed and in certain regions, among certain life forms, more than one fourth of all species may be dioECious (see below).

TLDR
The current focus is on the genetic mechanisms underlying unisexual flowers and individuals in plants' sedentary life style, which may often favor polygamous systems in which sexually inconstant individuals can persist.
The mechanism of sex determination in dioecious flowering plants.
On the rarity of dioecy in flowering plants
TLDR
There is an important need to consider more widely the possibility of transitions away from dioecy, both from an empirical and a theoretical point of view, and by combining tools from molecular evolution and insights from ecology.
Phylogenetic analysis of the ecological correlates of dioecy in angiosperms
TLDR
A phylogenetic analysis of correlations between the occurrence of dioecy and several ecological and life‐history attributes provided evidence for non‐independence between some of the traits, implying that functional associations among these traits have influenced the ecology and evolution of dIOecious species.
Dioecy is associated with higher diversification rates in flowering plants
TLDR
A new sister clade test is applied to a new data set obtained by searching the phylogenetic literature on more than 600 completely dioecious angiosperm genera and identifying 115 sisterClade pairs for which dIOecy is likely to be derived to confirm the preliminary result that dioECy is associated with an increased diversification rate.
