A latitudinal cline in flowering time in Arabidopsis thaliana modulated by the flowering time gene FRIGIDA.
A latitudinal cline in flowering time in accessions of Arabidopsis thaliana has been widely predicted because the environmental cues that promote flowering vary systematically with latitude, butExpand
Bar-Coded Pyrosequencing Reveals Shared Bacterial Community Properties along the Temperature Gradients of Two Alkaline Hot Springs in Yellowstone National Park
ABSTRACT An understanding of how communities are organized is a fundamental goal of ecology but one which has historically been elusive for microbial systems. We used a bar-coded pyrosequencingExpand
Role of Gene Interactions in Hybrid Speciation: Evidence from Ancient and Experimental Hybrids
The origin of a new diploid species by means of hybridization requires the successful merger of differentiated parental species' genomes. To study this process, the genomic composition of threeExpand
Quantitative trait loci for inflorescence development in Arabidopsis thaliana.
Variation in inflorescence development patterns is a central factor in the evolutionary ecology of plants. The genetic architectures of 13 traits associated with inflorescence developmental timing,Expand
Genotype-environment interactions at quantitative trait loci affecting inflorescence development in Arabidopsis thaliana.
Phenotypic plasticity and genotype-environment interactions (GEI) play a prominent role in plant morphological diversity and in the potential functional capacities of plant life-history traits. TheExpand
Genome expansion in three hybrid sunflower species is associated with retrotransposon proliferation
The origin of new diploid species through inter-specific hybridization may be facilitated by rapid genomic reorganization. There is evidence that this process was involved in the independent originsExpand
Novel loci control variation in reproductive timing in Arabidopsis thaliana in natural environments.
Molecular biologists are rapidly characterizing the genetic basis of flowering in model species such as Arabidopsis thaliana. However, it is not clear how the developmental pathways identified inExpand
Rapid hybrid speciation in wild sunflowers.
Hybrid or "recombinational" speciation refers to the origin of a new homoploid species via hybridization between chromosomally or genetically divergent parental species. Theory predicts that thisExpand
Genetics of microenvironmental canalization in Arabidopsis thaliana
Canalization is a fundamental feature of many developmental systems, yet the genetic basis for this property remains elusive. We examine the genetic basis of microenvironmental canalization in theExpand
