It is the time for all the all vegetarians to hold their breath and hear the news that they can be no more vegetarians. A taken task has been taken by the bio- technology researchers to convert all vegetarians to non vegetarians. The great future of this potato is it uses frog gene to resist pathogens. So we need to change the name of potato as FROGOTATO. In this potato a chemical that a south African frogs excrete from their skin and added to potatoes in order to resist with diseases which are supposed to come. This particular breed of potato is especially meant to grow in the semi arid regions with less water resources like Rajasthan etc. The frog from which the gene is taken mentioned below:

A chemical that South American frogs excrete from their skin could protect potatoes and other crops from a range of diseases, according to biotechnologists in Canada. The genetically  modified (GM) potatoes showed resistance to infection by a broad range of disease-causing fungi and bacteria, including those responsible for diseases such as dry rot, late blight and pink rot.

The tree frog Phyllomedusa bicolor produces chemicals with antibiotic properties from its skin Different species of frog produce different sets of chemicals, including some called dermaseptins, from their skin depending on the environment they inhabit. The chemicals help protect frogs from bacteria and other ‘pathogens’. The most potent dermaseptin, known as B1, has been isolated from the skin of tree frogs called Phyllomedusa bicolor that live in the rainforests of South America, where the hot and humid conditions mean fungi and bacteria thrive a synthetic version of dermaseptin B1 inhibited the growth of “an exceptionally broad range” of fungi that cause plant diseases, as well as the bacterium Erwinia carotovora, which causes blackleg in potato plants in the field and soft rot of tubers in storage.

The researchers genetically modified potatoes to produce the chemical and  exposed the GM plants to the same organisms. The inserted gene gave “unusually broad-spectrum and powerful resistance to infection”, according to the team’s research, which the journal Theoretical and Applied Geneticspublished online in June.

The researchers say that the preliminary results of studies to show the safety of dermaseptin B1 “are positive”. They add that the GM plants showed no ill effects of having been genetically modified. But yet it is important to test if dermaseptin B1 is toxic to people and animals, as well as study whether the chemical gets broken down or builds up in the body. Long-term effects must be taken into consideration because even though the authors claim that the amount of dermaseptin is low, the accumulation effect can’t be ignored.
