	abstract = {A fungal association has been described in the roots of three species of lsoetes which flourish during the rainy season in Rajasthan (India). The mycelium is septate, branched and forms bunches of intracellular hyphae in cortical cells of young roots. The association is symbiotic and is not influenced by habitat, i.e. while the host plant is aquatic, amphibious or terrestrial. This is the first report of a fungal association with the roots of the taxon Isoetes.},

	abstract = {The genetic diversity of 56 individuals of Iso{\"e}tes hypsophila Hand.-Mazz. from China was investigated by ISSR. Twelve primers were screened from 65 primers, and a total of 119 DNA fragments were scored, of these, 82\% were polymorphic bands, which indicated that high levels of genetic variation existed in the natural populations. Genetic diversity varied greatly among populations with the percentage of polymorphic band (PPB) values ranging from 8 to 35\%. An analysis of molecular variance (AMOVA) was used to apportion the variation between regions, among populations within regions, and within populations. Results indicated that most of the variance (85\%) occurred between Yunnan and Sichuan. The variances among populations within regions and within populations, however, were only 5 and 10\%, respectively. In the among-population analysis, the larger part of genetic variation (77\%) resided among populations, and less (23\%) presented differences within populations. UPGMA cluster analysis showed that there was no distinct genetic differentiation between populations from Sichuan province. A number of causes including limited gene flow, genetic drift and inbreeding might have led to these observed genetic profiles of I. hypsophila. {\textcopyright} 2005 Elsevier B.V.

	abstract = {Isoetes coreana Chung and Choi is on the list of critically endangered species in South Korea. Using randomly amplified polymorphic DNA (RAPD) markers, we investigated the genetic diversity within and between seven local populations of I. coreana. Ten RAPD primers produced a total of 94 bands, of which 59 (62.8\%) were polymorphic. A low level of genetic diversity was recognized within the populations of I. coreana: polymorphic loci (P), with values ranging from 3.4\% to 33.9\%, and a mean value of 15.5\% being observed. Analysis of molecular variance (AMOVA) showed that genetic diversity was greater among populations (81.6\%) than within populations (19.7\%) or among the three regions included in this study (Han River, Youngsan River, and Nakdong River). In addition, a high degree of genetic differentiation (θB = 0.742) was detected among the populations. These results indicate that genetic differentiation has occurred very rapidly. However, the rate of gene flow between populations was found to be as low as 0.059, irrespective of the genetic and geographical distances between the populations, which indicates that genetic drift must have played an important role in forming the present populations of I. coreana. Because a reduction of genetic diversity as a result of genetic drift is undesirable, increasing the gene flow between populations of Korean quillwort I. coreana should be considered as a conservation strategy. {\textcopyright} 2008 Elsevier B.V.

	abstract = {Isoetes sinensis (Isoetaceae), an aquatic quillwort which occurs only in two fragmented sites of China as an allotetraploid, is critically endangered. Genetic variation among eight subpopulations of I. sinensis was examined in the Xin{\textquoteright}an River (119{\textdegree}14'-15'E, 29{\textdegree}28'N) by using allozyme polymorphism. Eighteen loci of 10 enzyme systems were examined and used for the analysis of population genetic parameters. As expected for allotetraploids, fixed heterozygosity was found at four loci. A high level of genetic diversity was observed in the population, with mean number of alleles per loci of 1.8, and mean percentage of polymorphic loci of 55.6\%, which were much higher than the average values in fern species. The genetic variation within each subpopulation was not positively correlated with its size, which may be explained by high gene flow (Nm = 2.57), clonal reproduction and fixed heterozygosity of allopolyploid. The I. sinensis population contained high clonal diversity (PD = 0.39, D = 0.95), indicating the successful seedling recruitment of the population. Significant positive relationship was detected between clonal diversity and the size of subpopulation. Partitioning the genetic diversity indicated that 91.1\% of the genetic variation was within subpopulations and only 8.9\% existed among subpopulations. The migration pattern of I. sinensis along the Xin{\textquoteright}an River is best explained by a source-sink model, but with unidirectional gene flow among subpopulations underlined by hydrochoric force. The results were then discussed in relation to both in situ and ex situ conservation efforts of the population. {\textcopyright} 2008 Elsevier B.V. All rights reserved.},

	abstract = {Isoetes sinensis is a critically endangered aquatic quillwort, occurring in two fragmented sites of China (Xiuning county of Anhui; Jiande county of Zhejiang). During a five-year period (2004-2009), the areas and sizes of the two populations diminished dramatically due to intensive human activities. Genetic structure of the species was investigated using simple sequence repeat makers (SSRs). For seven nuclear microsatellites, high levels of genetic diversity were found within populations (H E=0.324-0.447). Strong genetic differentiation was detected between populations (G ST=0.376), while weak genetic differentiation was found within populations (G ST=0.026-0.080). Notably, in contrast to the source-sink model suggested by previous study (Chen et al., 2009), the migration pattern of I. sinensis along the Xin{\textquoteright}an River is best explained by the linear symmetrical non-adjacent flow model (LSNF), which indicates that intensive human activities of recent years have greatly affected the gene exchange pattern among I. sinensis subpopulations. {\textcopyright} 2011 Elsevier B.V.},
