Snapdragon genes, anti-cancer prope

New Delhi: When European scientists genetically modified a tomato with DNA from the snapdragon flower in 2008, the result was a through-and-through purple tomato with anti-cancer properties. Fourteen years later, this royal-coloured GMO (genetically modified organism) has finally been approved by US regulators.

Earlier this month, the Animal and Plant Health Inspection Service (APHIS) of the US Department of Agriculture (USDA) deemed that the plant could be safely grown and bred in America. “We found the plant is unlikely to pose an increased plant pest risk compared to other cultivated tomatoes,” the USDA said in a statement.

Whether or not customers will bite remains to be seen. But from next year, people will most likely be able to buy seeds and grow GMO tomatoes. The researchers behind it have expressed their excitement that their “healthy” creation will finally be able to make the journey to American tables.

“This is fantastic, I never thought I would see this day. We are now one step closer to my dream of sharing healthy purple tomatoes with the many people excited to eat them,” Cathie Martin, a professor at the John Innes Centre in the UK, and one of the scientists involved in the research, said in a statement.

Here is a look at why purple tomatoes may be even more nutritious than regular tomatoes and the science behind themThe ‘purple tomato’ was created not just for its visual appeal but for its enhanced nutritional qualities.

It was first developed in the lab 14 years ago by an international team of researchers from Italy, UK, Germany and Netherlands.

The team introduced genes from the antirrhinum — a variety of plants commonly known by names like snapdragon, dragon flower, and dog flower — to grow purple tomatoes rich in anthocyanins.

Anthocyanins are naturally occurring pigments present in particularly high levels in berries such as blackberry, cranberry and chokeberry. They don’t have a flavour or smell of their own, although their presence brings a slig
