      The South Asian populations have a mosaic of ancestries likely due to the interactions of long-term populations of the landmassand those of East andWest Eurasia. Apart from prehistoric dispersals, there are some known population movements to India. Inthis study,we focussed on the migration of Jewish and Parsi populations on temporal and spatial scales. The existence of Jewishand Parsi communities in India are recorded since ancient times. However, due to the lack of high-resolution genetic data, theirorigin and affiliation with other Indian and non-Indian populations remains shrouded in legends. Earlier genetic studies onpopulations of Indian Jews have found evidence for a minor shared ancestry of Indian Jews with Middle Eastern (Jews)populations, whereas for Parsis, the Iranian link was proposed. Recently, in our high-resolution study, we were able to quantifythe admixture dynamics of these groups, which has suggested a male-biased admixture. Here, we added the newly availableancient samples and revisited the interplay of genes and cultures. Thus, in this study we reconstructed a broad genetic profile ofIndian Jews and Parsis to paint a fine-grained picture of these ethnic groups.

      Forthcoming Special issue.


    • To trigger further research on plant mitochondria, the Journal of Biosciences is bringing out a special issue titled "Plant Mitochondria: Properties and Interactions with Other Organelles".


      Plant mitochondria are quite distinct and have unique features, such as a cyanide-insensitive alternate pathway. They also interact with chloroplasts to optimize photosynthetic carbon assimilation.


      Submissions are welcome until 30 July 2023. The contributions can be original articles, short communications, reviews, or mini-reviews on any topic related to plant mitochondria.


      Authors can submit their articles online at https://www.editorialmanager.com/jbsc/default2.aspx
