Intraspecific genetic variation in natural populations governs their potential to overcome challenging ecological and environmental conditions. In addition, knowledge of this variation is critical for the conservation and management of endangered plant taxa. Despite its wide distribution across the entire Himalayan range, the current status of Podophyllum hexandrum, a highly important anti-cancerous herb, remains endangered. In a new study published in AoB PLANTS, Nag et al. characterized the genetic diversity of 24 populations comprising 209 individuals representing the whole of the Indian Himalayas, and found that regardless of geographic location, all of the populations were intermixed and composed broadly of two types of genetic populations. Their findings suggest that these populations have evolved well in response to the environment. This study will help in the formulation of conservation programs for P. hexandrum populations in this region.
