Some cut flower species such as gentian and iris do not accumulate pelargonidin derived pigments and thus lack flowers with an intense red colour. Production is now consolidated in South America, from where there are good air-freight distribution systems to Europe, Japan and North America.
As carnation is insect pollinated in the wild and does not produce air-borne pollen, respiratory allergenicity has not been reported. When the researchers injected the engineered bacteria into a white rose petal, the bacteria transferred the pigment-producing genes to the rose genome, and a blue color spread from the injection site.
Although plant breeders were aware of some of the genes involved, there was as yet no quantitative study of how pigment Everything sounds prettier in French. A variety of colorful tulips take over the West Garden in the April.
