متن کاملA soybean quantitative trait locus that promotes flowering under long days is identified as FT5a, a FLOWERING LOCUS T ortholog
FLOWERING LOCUS T (FT) is an important floral integrator whose functions are conserved across plant species. In soybean, two orthologs, FT2a and FT5a, play a major role in initiating flowering. Their expression in response to different photoperiods is controlled by allelic combinations at the maturity loci E1 to E4, generating variation in flowering time among cultivars. We determined the molec...
متن کاملThe Medicago FLOWERING LOCUS T homolog, MtFTa1, is a key regulator of flowering time.
FLOWERING LOCUS T (FT) genes encode proteins that function as the mobile floral signal, florigen. In this study, we characterized five FT-like genes from the model legume, Medicago (Medicago truncatula). The different FT genes showed distinct patterns of expression and responses to environmental cues. Three of the FT genes (MtFTa1, MtFTb1, and MtFTc) were able to complement the Arabidopsis (Ara...
متن کاملPhytochrome E influences internode elongation and flowering time in Arabidopsis.
From a screen of M2 seedlings derived from gamma-mutagenesis of seeds doubly null for phytochromes phyA and phyB, we isolated a mutant lacking phyE. The PHYE gene of the selected mutant, phyE-1, was found to contain a 1-bp deletion at a position equivalent to codon 726, which is predicted to result in a premature stop at codon 739. Immunoblot analysis showed that the phyE protein was undetectab...
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...
