Genetic and Phenotypic Variation for Flowering Time Genes in Barley (Hordeum vulgare)
Objective: Flowering Time (FT) in cereals controlled by genes that had a main factor on plant development. Methods: Genetic and phenotypic diversity of four flowering time genes (FT2, FT3, FT4, Ppd-H1) in 19 genotypes of cultivated and wild barley was evaluated and a total of 107 alleles were amplified. Genotypes based on days to flowering time and molecular data were grouped into earl...

متن کاملExtreme Mitogenomic Variation in Natural Populations of Chaetognaths
The extent of within-species genetic variation across the diversity of animal life is an underexplored problem in ecology and evolution. Although neutral genetic variation should scale positively with population size, mitochondrial diversity levels are believed to show little variation across animal species. Here, we report an unprecedented case of extreme mitochondrial diversity within natural...
متن کاملRole of FRIGIDA and FLOWERING LOCUS C in determining variation in flowering time of Arabidopsis.
Arabidopsis (Arabidopsis thaliana) accessions provide an excellent resource to dissect the molecular basis of adaptation. We have selected 192 Arabidopsis accessions collected to represent worldwide and local variation and analyzed two adaptively important traits, flowering time and vernalization response. There was huge variation in the flowering habit of the different accessions, with no simp...
متن کاملGenetic Architecture of Flowering-Time Variation in Arabidopsis thaliana
The onset of flowering is an important adaptive trait in plants. The small ephemeral species Arabidopsis thaliana grows under a wide range of temperature and day-length conditions across much of the Northern hemisphere, and a number of flowering-time loci that vary between different accessions have been identified before. However, only few studies have addressed the species-wide genetic archite...
