A recent study by researchers at the Indian Institute of Science, Education and Research (IISER) Kolkata, has resulted in the development of a novel molecular ‘switch’ that turns on in the presence of specific proteins.
The study from IISc found a previously unidentified yeast-like symbiont inside the lac insect Kerria lacca, which gives the insect its distinctive red colour and, may also provide other nutrients in return for shelter.
