	abstract = {A relict population of Iso{\"e}tes echinospora Durieu survived a thirty-year period of severe acidification and high concentrations of phytotoxic aluminium (Al) in Ple{\v s}n{\'e} Lake (Bohemian Forest, Czech Republic). The population consisted of only adult plants. Sporeling survival and age structure were examined during the population recovery in 2004-2008. Laboratory experiments were conducted to assess the effect of various pH values (4-8) and Al concentrations (0-1000 μgl -1) on sporeling development. The responses of the sporelings to the experimental treatments were evaluated and compared with those observed in the lake. The experiments showed that an Al concentration higher than 300 μgl- 1 , and high acidity (pH 4), inhibit sporeling growth, in particular resulted in a pronounced reduction in absorptive organs (macrogametophyte rhizoids, roots and root hairs). With increasing concentrations of Al and at pH 4, the ratio of the below-ground to above-ground sporeling biomass decreased to less than 1. The responses of the lake sporelings, rooting in the upper sediment layer, were similar to those exposed to 100-300 μgl -1 of Al in the laboratory, and reflected the Al toxicity of the lake water. The quillworts at Ple{\v s}n{\'e} Lake survived because adult plants can tolerate these adverse conditions and are very long-lived. The population recovered when the pH of the water increased to over 5 and the Al concentration decreased to below 300 μgl- 1 .},

These submerged lycopsids are the only macrophyte species inhabiting the bottom of two acidified glacial lakes in the Czech Republic. Arbuscular mycorrhizal (AM) fungi were detected in the roots of both species but the percentage of root colonization was both low and variable. Nevertheless, planting Littorella uniflora in the sediments from Iso{\"e}tes rhizosphere revealed high levels of viable AM propagules in both lakes. While AM colonization of Iso{\"e}tes roots did not exceed 25\%, the average colonization of Littorella roots amounted to more than 80\%. Although colonization of quillwort roots by AM fungi is evident, the taxonomic identity and role of these AM fungi in plant growth remain unclear. In addition to AM fungi, root-colonizing dark septate endophytic fungi were observed in both Iso{\"e}tes species. {\textcopyright} 2011 Elsevier B.V.},

	abstract = {Isoetes hypsophila Hand.-Mazz. (Isoetaceae) is an endangered alpine quillwort endemic to the Qinghai-Tibetan Plateau (QTP). A total of 247 individuals of I. hypsophila from 11 populations were analyzed using ten pairs simple sequence repeats (SSR) markers. Seventy-seven alleles were recorded, with an average of 7.7 alleles per locus (ranging from 3 to 12) and the expected heterozygosity (HE) ranged from 0.392 to 0.536 (average 0.471). Clear population structure among I. hypsophila populations was found and the proportion of genetic differentiation among populations accounted for about 20\% of total genetic diversity (FST = 0.178; probability of allelic co-ancestory Fcoal = 0.238). This genetic structure was probably due to limited gene flow hindered by complex terrains, bottlenecks resulting from water fluctuation in habitats, and repeated population retreat and recolonization during the ice ages. In conservation, four management units corresponding to four geographic regions were suggested, and the populations from different management units with higher genetic variation should be the priority targets of both in situ and ex situ conservation. {\textcopyright} 2012 Elsevier Ltd.},
