Molecular Regulation of Flowering Time in Grasses
Flowering time is a key target trait for extending the vegetative phase to increase biomass in bioenergy crops such as perennial C4 grasses. Molecular genetic studies allow the identification of genes involved in the control of flowering in different species. Some regulatory factors of the Arabidopsis pathway are conserved in other plant species such as grasses. However, differences in the func...
متن کاملRegulation of flowering time by Arabidopsis MSI1.
The transition to flowering is tightly controlled by endogenous programs and environmental signals. We found that MSI1 is a novel flowering-time gene in Arabidopsis. Both partially complemented msi1 mutants and MSI1 antisense plants were late flowering, whereas ectopic expression of MSI1 accelerated flowering. Physiological experiments revealed that MSI1 is similar to genes from the autonomous ...
متن کاملRegulation of flowering time by Arabidopsis photoreceptors.
The shift in plants from vegetative growth to floral development is regulated by red-far-red light receptors (phytochromes) and blue-ultraviolet A light receptors (cryptochromes). A mutation in the Arabidopsis thaliana CRY2 gene encoding a blue-light receptor apoprotein (CRY2) is allelic to the late-flowering mutant, fha. Flowering in cry2/fha mutant plants is only incompletely responsive to ph...
متن کاملRegulation of flowering time by histone acetylation in Arabidopsis.
The Arabidopsis autonomous floral-promotion pathway promotes flowering independently of the photoperiod and vernalization pathways by repressing FLOWERING LOCUS C (FLC), a MADS-box transcription factor that blocks the transition from vegetative to reproductive development. Here, we report that FLOWERING LOCUS D (FLD), one of six genes in the autonomous pathway, encodes a plant homolog of a prot...
