Re: where can i find a dna sequences of kudzu and grapes

Hi Peyton,

It would be fantastic to transform kudzu from an invasive pest into a useful crop plant, but what you are proposing is not yet within the reach of current technology.

Although the genome of the grapevine (Vitis vinifera) has been sequenced, the function of most of the genes remains unknown. The development of grapes on the vine is a very complex process, and is controlled not by one or a few genes, but rather by dozens if not hundreds of genes acting in a coordinated fashion, only some of which are known and understood. This is why you cannot find any source that will tell you the specific genes needed.

In addition, while it is possible to transfer genes from one plant to another, it is a complicated process, and can only be done one or a few genes at a time.

Although kudzu has caused a lot of trouble in the Southeastern US, it does have some uses. It was introduced to the United States as a forage plant for livestock. In addition, it can fix nitrogen, which can improve the soil, and its extensive root system can prevent soil erosion as well as bring mineral nutrients from the subsoil to the surface. Because of the useful properties it does have, kudzu may be a good candidate for breeding programs. For example, it may be possible to breed a variety of kudzu that is still useful as a forage crop, but does not grow so aggressively.
