Anyway you slice it, tomatoes cut through drought with new gene

New tomato research has its roots in yielding more food to feed more people, according to Dr. Kendal Hirschi about results announced today. The team made tomato plants over-express the gene, AVP1, which resulted in stronger, larger root systems and that resulted in roots making better use of...

Tastier tomatoes in the future?

Tomatoes are good for you. They strengthen the immune system and can prevent heart and circulatory disease. Now, researchers from the Max Planck Institute of Molecular Plant Physiology, in co-operation with Israeli scientists, have identified DNA fragments in tomatoes that make their contents both healthy and tasty. The researchers crossed wild tomatoes with cultured ones, then investigated the c...

Unique tomatoes tops in disease-fighting antioxidants

Deep red tomatoes get their rich color from lycopene, a disease-fighting antioxidant. A new study, however, suggests that a special variety of orange-colored tomatoes provide a different form of lycopene, one that our bodies may more readily use. Researchers found that eating spaghetti covered in sauce made from these orange tomatoes, called Tangerine tomatoes, caused a noticeable boost in...

Scientists genetically engineer tomatoes with enhanced folate content

Leafy greens and beans aren't the only foods that pack a punch of folate, the vitamin essential for a healthy start to pregnancy. Researchers now have used genetic engineering--manipulating an organism's genes--to make tomatoes with a full day's worth of the nutrient in a single serving. The scientists published their results in this week's online edition of the journal PNAS, Proceedings o...

Protective effects of tomatoes in prostate cancer

Diets rich in tomato products, such as tomato sauce and ketchup, have long been associated with a reduced risk of various cancers, especially prostate cancer, but the reason for such an action is yet to be found. Clinical trials have suggested that lycopene, which is found in tomato products and other natural plant nutrients may be effective in preventing prostate cancer and treating t...

Tomatoes for the heart

A genetically modified tomato which could make for more heart-friendly products has been developed by European scientists. Martine Verhoeyen of Unilever Research in the UK and colleagues, describe how they boosted the production of rutin, a compound found in the skin of tomatoes. Rutin is a flavonol, part of a larger group of compounds called flavenoids, and is believed to be a powerf...

Tomatoes Might Inhibit the Development Of Prostate Cancer

A new study finds that lycopene is not the only compound in tomatoes that could prevent prostate cancer.Lycopene is a carotenoid in tomatoes that gives //them that familiar red color. Research has suggested lycopene could reduce the risk of prostate cancer. But it is unclear if lycopene itself is responsible for the risk reduction. Researchers from the University of Illinois studied th...

Hearty tomatoes

A research group in Germany has successfully inserted genetic material into the chloroplasts of a tomato plant, increasing the potential for edible medicines and reducing the risk of cross-pollination. Chloroplasts are plastids - packages outside the cell nucleus that contain pigments, in this case the green pigment chlorophyll. It is the first time that foreign genes have been introdu...

Roma tomatoes the culprits for salmonella infection

Normally salmonella infectins are caused by non veg items but now roam tomatoes have been found to cause them//. US govt has now revealed that three outbreaks in 2004 were caused by this agent.
