The genetic variability of four natural populations of Larix gmelinii from East Siberia was determined and compared by RAPD analysis. Comparison of the RAPD profiles provided an estimation of
variability in 193 RAPD fragments. More than 89% of these fragments were found to be polymorphic. The main genetic variability
parameters of the two populations from Central Yakutia, a region free of fluoride pollution, had considerably higher values
than those from East Transbaikalia, a region potentially affected by fluoride pollution (FLU, near a fluorite quarry growing
on soils with a high natural content of fluorides). AMOVA revealed that 72.94% of the variation was within populations, while
only 7.05% of the variation was between populations within geographical regions. The genetic diversity of the FLU fluoride-tolerant
population was the lowest, but only slightly lower than that of a fluoride non-tolerant population from Chita, 50 km distant
from FLU. Although this study demonstrates the absence of fundamental alterations of genetic structure within the populations
of L. gmelinii growing on soils with a high content of fluorides, it is presumed that the reduction of genetic diversity was the genetic
response of the FLU population to such an environmental stress as a constantly high concentration of fluorides within the
soil. 相似文献
