Major-Effect Alleles at Relatively Few Loci Underlie Distinct Vernalization and Flowering Variation in Arabidopsis Accessions
We have explored the genetic basis of variation in vernalization requirement and response in Arabidopsis accessions, selected on the basis of their phenotypic distinctiveness. Phenotyping of F2 populations in different environments, plus fine mapping, indicated possible causative genes. Our data support the identification of FRI and FLC as candidates for the major-effect QTL underlying variatio...
متن کاملInteraction of Photoperiod and Vernalization Determines Flowering Time of Brachypodium distachyon1[C][W][OPEN]
Timing of flowering is key to the reproductive success of many plants. In temperate climates, flowering is often coordinated with seasonal environmental cues such as temperature and photoperiod. Vernalization is an example of temperature influencing the timing of flowering and is defined as the process by which a prolonged exposure to the cold of winter results in competence to flower during th...

متن کاملNatural Variation of the RICE FLOWERING LOCUS T 1 Contributes to Flowering Time Divergence in Rice
In rice (Oryza sativa L.), there is a diversity in flowering time that is strictly genetically regulated. Some indica cultivars show extremely late flowering under long-day conditions, but little is known about the gene(s) involved. Here, we demonstrate that functional defects in the florigen gene RFT1 are the main cause of late flowering in an indica cultivar, Nona Bokra. Mapping and complemen...
متن کاملGenetic 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...
