	abstract = {We examined chloroplast trnL intron sequence variation within Isoetes hypsophila, a Chinese endemic alpine quillwort species. Sequence data were obtained from 46 individuals in six populations throughout the natural distribution of the species. Sequences appeared to have neutral evolution (Tajima{\textquoteright}s criterion D = -1.66453, 0.1 \&gt; P \&gt; 0.05; Fu and Li{\textquoteright}s test D* = -1:92897, 0.1 \&gt; P \&gt; 0.05; F* = -2.17823, 0.1 \&gt; P \&gt; 0.05). Eleven haplotypes were identified in I. hypsophila. A relatively high level of haplotype diversity (h = 0.817) and a low level of nucleotide diversity (π = 0:0045) were detected in I. hypsophila. Indirect estimates of gene flow based on cpDNA variation revealed significant genetic differentiation between the ZD1 population in Yunnan Province and the populations from Sichuan Province. High genetic differentiation between Yunnan and Sichuan populations was consistently indicated by both hierarchical analyses of molecular variance (AMOVA; GST = 0.5011) and the structure of a neighbor-joining tree. From nested clade analysis, restricted gene flow with isolation by distance was inferred to be responsible for the current spatial genetic structure of I. hypsophila. {\textcopyright} 2008 by The University of Chicago.

	abstract = {Isoetes yunguiensis is an endangered and endemic fern in China. Field survey indicated that only one population and no more than 50 individuals occur in the wild. The genetic variation of 46 individuals from the population remaining at Pingba (Guizhou Province, China) was assessed by Random Amplified Polymorphic DNA (RAPD) finger-printing. Twelve primers were screened from sixty ten-bp arbitrary primers, and a total of 95 DNA fragments were scored. Of these, 62.1\% were polymorphic loci, which indicated that high level genetic variation existed in the natural population. The accumulation of genetic variation in the history of the taxon and the apparent minimal reduction effect on genetic diversity following destruction of habitat might be responsible for the high level genetic diversity presently remaining in the I. yunguiensis population. However, with the continuing decrease of population size, the genetic diversity will gradually be lost. We suggest that the materials from the extant population should be used for re-establishment of the populations. {\textcopyright} 2007 Higher Education Press and Springer-Verlag.},
