Comparative mapping reveals autosomal origin of sex chromosome in octoploid Fragaria virginiana.
Recent evolution of separate sexes in flowering plants provides unparalleled opportunities for understanding the early stages of sex chromosome evolution, including their origin from autosomes. Moreover, the transition from combined to separate sexes can be associated with speciation via polyploidization in angiosperms, suggesting that genome doubling/merger may facilitate sterility mutations r...
متن کاملA New Perspective on Polyploid Fragaria (Strawberry) Genome Composition Based on Large-Scale, Multi-Locus Phylogenetic Analysis
The subgenomic compositions of the octoploid (2n = 8× = 56) strawberry (Fragaria) species, including the economically important cultivated species Fragaria x ananassa, have been a topic of long-standing interest. Phylogenomic approaches utilizing next-generation sequencing technologies offer a new window into species relationships and the subgenomic compositions of polyploids. We have conducted...
متن کاملNew features in the genus Ilarvirus revealed by the nucleotide sequence of Fragaria chiloensis latent virus.
Fragaria chiloensis latent virus (FClLV), a member of the genus Ilarvirus was first identified in the early 1990s. Double-stranded RNA was extracted from FClLV infected plants and cloned. The complete nucleotide sequence of the virus has been elucidated. RNA 1 encodes a protein with methyltransferase and helicase enzymatic motifs while RNA 2 encodes the viral RNA dependent RNA polymerase and an...
متن کاملIdentification of volatile compounds associated with the aroma of white strawberries (Fragaria chiloensis).
BACKGROUND Fragaria chiloensis (L.) Mill spp. chiloensis form chiloensis, is a strawberry that produces white fruits with unique aromas. This species, endemic to Chile, is one of the progenitors of Fragaria x ananassa Duch. In order to identify the volatile compounds that might be responsible for aroma, these were extracted, and analyzed by gas chromatography-mass spectrometry (GC-MS), gas chro...
متن کاملSex ratio and subdioecy in Fragaria virginiana: the roles of plasticity and gene flow examined.
Here we examined the roles of sex-differential plasticity (SDP) and gene flow in sex ratio evolution of subdioecious Fragaria virginiana. We assessed whether female frequency varied with resource availability in 17 natural populations and then characterized plasticity and mean investment in allocation to female function at flower and plant levels in the sex morphs in the glasshouse. We estimate...
