A Gradual Process of Recombination Restriction in the Evolutionary History of the Sex Chromosomes in Dioecious Plants
To help understand the evolution of suppressed recombination between sex chromosomes, and its consequences for evolution of the sequences of Y-linked genes, we have studied four X-Y gene pairs,Expand
SlY1, the first active gene cloned from a plant Y chromosome, encodes a WD‐repeat protein
Unlike the majority of flowering plants, which possess hermaphrodite flowers, white campion (Silene latifolia) is dioecious and has flowers of two different sexes. The sex is determined by theExpand
Analysis and evolution of two functional Y-linked loci in a plant sex chromosome system.
White campion (Silene latifolia) is one of the few examples of plants with separate sexes and with X and Y sex chromosomes. The presence or absence of the Y chromosome determines which type ofExpand
Low variability in a Y-linked plant gene and its implications for Y-chromosome evolution
Sex chromosomes have evolved independently in several different groups of organisms, but they share common features, including genetic degeneration of the Y chromosome. Suppression of recombinationExpand
Evidence for Degeneration of the Y Chromosome in the Dioecious Plant Silene latifolia
The human Y--probably because of its nonrecombining nature--has lost 97% of its genes since X and Y chromosomes started to diverge [1, 2]. There are clear signs of degeneration in the DrosophilaExpand
Isolation of early genes expressed in reproductive organs of the dioecious white campion (Silene latifolia) by subtraction cloning using an asexual mutant.
The dioecious white campion (Silene latifolia) has been chosen as a working model for sexual development. In this species, sexual dimorphism is achieved through two distinct developmental blocks:Expand
A Light-Regulated Genetic Module Was Recruited to Carpel Development in Arabidopsis following a Structural Change to SPATULA[W]
This study provides insight into the evolution of flowering plants by demonstrating that a mechanism that modulates carpel margin development in Arabidopsis was recruited from light-regulatedExpand
Independent Origin of Sex Chromosomes in Two Species of the Genus Silene
Here we introduce a new model species, Silene colpophylla, that could facilitate research of sex chromosome evolution and sex-determining systems. This species is related to the well-establishedExpand
A Data-Driven Integrative Model of Sepal Primordium Polarity in Arabidopsis[C][W]
This study presents a new modeling approach allowing diverse types of data to be integrated in a coherent molecular regulatory network model. This was used to analyze sepal primordium development andExpand
Premature arrest of the male flower meristem precedes sexual dimorphism in the dioecious plant Silene latifolia
Most dioecious plant species are believed to derive from hermaphrodite ancestors. The regulatory pathways that have been modified during evolution of the hermaphrodite ancestors and led to theExpand
