Krishna Tulasi Tree

DNA barcodes of various biogeographical isolates of Tulsi from the Indian subcontinent are now available. In a large-scale phylogeographical study of this species conducted using chloroplast genome sequences, a group of researchers from Central University of Punjab, Bathinda, have found that this plant originates from North Central India. The discovery might suggest the evolution of Tulsi is related with the cultural migratory patterns in the Indian subcontinent.
