Article Synopsis
- Anthropogenic activities, particularly large-scale grafting of crop species onto wild plants, are leading to significant genetic diversity loss in many species, including the iron walnut (Juglans sigillata) endemic to southwestern China.
- A study involving 149 grafted individuals from nine wild populations revealed that scions (the top part of the graft) had lower genetic diversity than their rootstocks (the base), with clear genetic separation in most populations, and instances of potential gene flow between crops and wild varieties.
- The findings suggest that extensive grafting practices are eroding genetic diversity and disrupting the genetic structure of wild J. sigillata populations, prompting calls for conservation measures to protect natural genotypes

Article Synopsis
- The common walnut (Juglans regia) is valued for its wood and nuts, with the Iranian Plateau being a key area for its genetic diversity and domestication.
- SSR markers were used to analyze 508 walnut individuals across 27 populations, revealing high genetic diversity with more variation within populations than between them.
- The study highlights the importance of conserving certain populations, particularly the low-diversity one in Iraq, and recommends preservation efforts for specific populations in Iran to maintain genetic resources.
Article Synopsis
- The study investigates the genetic diversity and population structure of 12 walnut populations across Pakistan, using 31 nuclear microsatellites to assess their characteristics.
- Findings reveal generally low genetic diversity among populations, with some exhibiting positive inbreeding coefficients, while one population in Upper Dir is notably distinct from others.
- The research highlights key areas with high genetic diversity that need conservation and suggests implications for future walnut breeding and conservation efforts in Pakistan.
