The Pink Double Dandy peony, the Double Peppermint petunia, the Doubled Strawberry Vanilla lily and nearly all roses are varieties cultivated for their double flowers.
The blossoms of these and other such plants are lush with extra petals in place of the parts of the flower needed for sexual reproduction and seed production, meaning double flowers – though beautiful – are mutants and usually sterile.
The genetic interruption that causes that mutation helped scientists in the 1990s pinpoint the genes responsible for normal development of sexual organs stamens and carpels in the plant Arabidopsis thaliana, long used as a plant model by biologists. (more…)
A rose by any other name would smell … like celery?
North Carolina State University research intended to extend the “vase life” of roses inserts a gene from celery inside rose plants to help fight off botrytis, or petal blight, one of the rose’s major post-harvest diseases.
Some fungal pathogens, the bad guys that infect plants, produce a sugar alcohol called mannitol that interferes with the plant’s ability to block disease like petal blight, which produces wilty, mushy petals – an effect similar to what happens to lettuce when it’s been in the crisper too long.
