Dioecy (separate male and female individuals) ensures outcrossing and is more prevalent in animals than in plants. Although it is common in bryophytes and gymnosperms, only 5% of angiosperms are dioecious. In dioecious higher plants, flowers borne on male and female individuals are, respectively deficient in functional gynoecium and roecium. Dioecy is inherited via three sex chromosome systems: XX/XY, XX/X0 and WZ/ZZ, such that XX or WZ is female and XY, X0 or ZZ are males. The XX/XY system… Expand
Dynamics of sex expression and chromosome diversity in Cucurbitaceae: a story in the making
TLDR
The present discussion brings the genera in light, previously recognized under subfamily Nhandiroboideae, where the study of chromosome cytology and sex determination mechanisms can simplify the understanding of sex expression pathways and its phylogenetic impacts. Expand
Evidence for Emergence of Sex-Determining Gene(s) in a Centromeric Region in Vasconcellea parviflora
TLDR
The results suggest that mutation of gene(s) in the centromeric region may have triggered sex chromosome evolution in these plant species. Expand
Genetic control of flowering in greater yam (Dioscorea alata L.)
TLDR
A genome-wide association approach was used and identified a major genetic barrier to reproduction in yam on chromosome 1, as represented by two candidate genes, which could facilitate the design of future promising parental combinations in D. alata breeding programs. Expand
Genome-Wide Association Studies for Sex Determination and Cross-Compatibility in Water Yam (Dioscorea alata L.)
TLDR
This study identified 54 markers linked to flower sex determination, among which 53 markers were on chromosome 6 and one on chromosome 11, and ascertained that D. alata is characterized by the male heterogametic sex determination system (XX/XY). Expand
Gender Determination of Date Palm
TLDR
This chapter is focused on an understanding of floral biology, genetics of sex, and methods applied for sex determination in date palm. Expand
Sex Chromosomes of the Iconic Moth Abraxas grossulariata (Lepidoptera, Geometridae) and Its Congener A. sylvata
TLDR
The results suggest a relatively rapid molecular divergence of Abraxas W chromosomes by the independent spreading of female-specific repetitive sequences, and cross-species W-chromosome painting revealed considerable sequence differences between them. Expand
Proteomics in Sex Determination of Dioecious Plants
TLDR
This chapter outlines the primary methods, especially proteomics, in sex determination of dioecious plants, and summarize the current applications, and discusses the limitations and future of proteomics in sex determined plants. Expand
Origin and Evolution of the Neo-Sex Chromosomes in Pamphagidae Grasshoppers through Chromosome Fusion and Following Heteromorphization
TLDR
Details of the heteromorphization of the neo-sex chromosomes in species from both phylogenetic lineages of Pamphagidae grasshoppers are revealed and the hypothetical mechanism of the Neo-Y degradation was suggested. Expand
Chromosomal localization of 45S rDNA, sex-specific C values, and heterochromatin distribution in Coccinia grandis (L.) Voigt
TLDR
The present study aids in the cytogenetic characterization of four native populations of this plant employing distribution patterns of 45S rDNA on chromosomes and guanine-cytosine (GC)-rich heterochromatin in the genome coupled with flow cytometric determination of genome sizes. Expand
Sexual systems in gymnosperms: A review
Abstract The aim of this study was to update figures for the presence of dioecy among the gymnosperms and investigate its correlation with climate, growth form, pollination and seed dispersalExpand

GENETICS OF SEX EXPRESSION IN FRAGARIA SPECIES
TLDR
Flower organogenesis, acts as an inducer of microsporogenesis in females, but leaves both microand megasporangial development intact, and application of phytohormones alters sex expression to a limited extent. Expand
Recent Origin of Dioecious and Gynodioecious Y Chromosomes in Papaya
TLDR
It is indicated that Y and Yh chromosomes evolved from a common ancestral Y chromosome, possibly prior to the origin of agriculture, and the existence of a hermaphrodite Yh chromosome is less likely to have resulted from human selection as once suggested. Expand
Sex determination and the evolution of dioecy from monoecy in Sagittaria latifolia (Alismataceae)

  • 2004
TLDR
The genetic and environmental determinants of sex in Sagittaria latifolia, a species with both monoecious and dioecious populations, are investigated and results are consistent with predictions for the evolution of dioECy via gynodioecy, rather than the expected monoecy–paradioecY pathway. Expand
Sex determination in dioecious species of plants
TLDR
Evidences suggest that the change from bisexuality to unisexuality and homomorphicity to heteromorphicity in chromosomes had been a short step in evolution possibly occurring in the recent past. Expand
Sex chromosomes in land plants.
Sex chromosomes in land plants can evolve as a consequence of close linkage between the two sex determination genes with complementary dominance required to establish stable dioecious populations,Expand
Evolution of Neo-Sex Chromosomes in Silene diclinis
TLDR
Evolution of neo-sex chromosomes may be the cause of partial reproductive isolation of this species and could have been the isolating mechanism that drove speciation of S. diclinis. Expand
The mechanism of sex determination in dioecious flowering plants.
TLDR
In plants it is possible to follow both the evolution of dioecism from hermaphroditism (or monoecism) and the reverse process, and in many cases, better tools for studying the genetics of sex determination thandioecious animals. Expand
Construction of physical maps for the sex-specific regions of papaya sex chromosomes
TLDR
The 89% increase of DNA sequence in HSY indicates rapid expansion of the Yh chromosome after genetic recombination was suppressed 2–3 million years ago, and is essential for sequencing these X and Yh-specific regions. Expand
Sexual dimorphism in white campion: complex control of carpel number is revealed by y chromosome deletions.
TLDR
Experimental support is brought to the existence on the Y chromosome of genic meiotic drive function(s) and, on the other hand, to models that consider that dioecy evolved through multiple mutation events. Expand
