Roses with celery gene: a new method of self-defense for flowers


12/02/2011

Study of North Carolina State University intends to expand the scope of "flowerpot life" rose by embedding them in a celery gene to help plants against Botrytis fungus (botrytis) or petal wilting, one of the major diseases of roses after their maturation.

Some fungalnye pathogens, the bad guys that infect plants, produce a sugar alcohol called mannitol (mannitol), which interferes with the ability of plants to block like a mop with wilt disease, which makes the petals wilted and soft - the effect is similar to what happens with a salad that is too long lain on the sandwich.

In an effort to extend the life of roses to get more revenue from gifts on Valentine’s Day, State of North Carolina, horticultural scientists, Dr. John Dole (John Dole) and Dr. John Williamson (John Williamson), attempts to make the introduction of a gene called the celery mannitol dehydrogenase in roses. In this way, they hope to help the roses "fight" with mannitol and allow the plant to defend itself from one of its greatest threats.

"This gene is found naturally in many plants, but it is not known whether it is present in the roses" - said Williamson. "If so, then perhaps it produces an insufficient amount of enzyme to help fight the plants with leaf wilt."

Genetically modified roses currently grown in the laboratory in the State of North Carolina study, look and smell like "normal" roses. Now the roses will be tested for the presence of superior abilities to resist fading petaled.

The study - it’s just part of the expanded efforts of the State of North Carolina to create the best roses, according to Dole. Other research includes the study of aspiration types of sugars, suitable well to mix with water to support plant life, plucked when ripe, the study of changes in water quality across the country, to see how and what kind of water will provide the best environment for the Roses after they will be cut, as well as search for other methods to prevent many serious diseases of plants.

The ultimate goal of the researchers - get roses that can persist for three to four weeks after they have matured and would be disrupted. Many roses that are sold in flower shops come from Colombia and Ecuador, so the longer the transportation, the less will last the life of flowers in a vase after the purchase.
