In a recent study, researchers from the Institute for Stem Cell Biology and Regenerative Medicine (InStem), Bengaluru, National Centre for Biological Sciences (NCBS), Bengaluru, Christian Medical College, Vellore and the Indian Institute of Technology, Kanpur, have described how a type of virus, called adeno-associated virus, behaves when injected into the mouse testis.
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.
