- Abstract
- Persian walnut (Juglans regia L) is an economically
important species cultivated worldwide for its wood and
nuts. Despite the increasing interest in the development of
conservation strategies for walnut germplasm, an accurate and
full-scale overview of wild genetic resources of J. regia has
not been conducted because natural populations are located in
regions of Asia historically difficult to access. In this study, we
estimated the genetic diversity and spatial genetic structure of
39 autochthonous Persian walnut populations sampled across
its Asian range using 14 neutral microsatellite markers. A
landscape genetic overlay approach was applied to detect the
areas of current reservoirs of walnut genetic diversity in the
Asian range and to evaluate the role of landscape in shaping
walnut genetic diversity since the Last Glacial Maximum.
Although Persian walnut has been highly manipulated by
humans over the last 2,000 years, we determined that patches
of high genetic diversity still exist in the Caucasus and mountains
of Central Asia where J. regia might have survived after
Pleistocene glaciations. We detected a clear separation of
Persian walnut into four main genetic clusters centered in (1)
western Kyrgyzstan, (2) western and south-central Asia, (3)
east-central Uzbekistan, and (4) Xinjiang and Shandong provinces
(China). Overlay of maps showed a coincidence between
groups of walnut populations and potential barriers to
gene flow such as the Hindu Kush, Pamir, Tien Shan, and
Himalaya mountains and the Karakum, Kyzyl Kum, and
Taklamakan deserts. This study claimed the relevance of the
preservation of walnut genetic resources in the Asian range. (literal)
