However, the small differences observed between the FRI-Ler and FRI-wt alleles expressed under the same promoter suggest that if real, the effect of these mutations on flowering time is minor compared to the effect of their differences in expression.
Mutation spectrum of flower shape variation included double inflorescence within one stalk, double stalk per plant, inflorescence without bracts, two-flag petal true flowers, and chlorophyll mutation in the leaves which are generally caused by induced gamma rays.
Irradiation induced some mutation spectrum of flower color variation that included colors such as purple, pale purple, rather pale purple, white, purple white (marbled pattern), and two-tone purple color.
The fo mutation increases floral size, [ 28] while the na mutation reduces plant height and leaf width without significantly affecting flower size while the Ni mutation reduces the sizes of flowers, leaves and internodes in a dosage-dependent fashion.
The ornamental crop Calluna vulgaris is of increasing importance to the horticultural industry in the northern hemisphere due to a flower organ mutation: the flowers of the 'bud-flowering' phenotype remain closed i.e. as buds throughout the total flowering period and thereby maintain more colorful flowers for a longer period of time than the wild-type.
In order to achieve a better understanding of mutations in flower morphology in this crop, an initial cloning of two MADS-box genes was realized in addition to preliminary expression analyses.
Common and rare FRI mutations along with rare FLC mutations explain a large fraction of flowering-time variation in A. thaliana.
Now that it has been shown that the bmr mutations of sorghum also affect the flowering time, the experimental population that can be used to determine the underlying effect has become significantly larger.
Natural mutations of AG orthologs are responsible for double flowers in varieties of ornamental cherry, morning glory and anemone.
