英文摘要	Tamarix taklamakanensis is an endangered shrub endemic to the Tarim Basin and adjacent Kumtag Desert in north-western China. Here, we used two chloroplast DNA sequences, namely, psbA-trnH and trnS- trnG, to examine the genetic diversity patterns of this species across its entire covered range. A total of nineteen haplotypes were detected. The total gene diversity within the species is high. Genetic variation mainly occurred among populations, SAMOVA groups, and geographic regions. The test for isolation-by-distance showed a significant correlation between genetic and geographical distances, and the genetic landscape shape analysis showed a significant genetic divergence between the Tarim Basin and Kumtag Desert. T. taklamakanensis likely had a potential geographic range during the Last Glacial Maximum period that was much smaller than the present range predicted by ecological niche modelling. The cold and dry climate during the glacial periods of the Quaternary might be a driver of the genetic isolation and divergence detected within T. taklamakanensis, and climatic oscillations might account for the habitat fragmentation of the species. Within the inner of the basin, populations have a higher level of genetic diversity and harbor most of this genetic diversity, thus a nature reserves should be set up in this area for the in situ conservation. In addition, five genetically distinct groups within T. taklamakanensis should be treated as different management units (MUs) when implementing conservation activities.
