	abstract = {Isoetes hypsophila Hand.-Mazz. (Isoetaceae) is an endangered quillwort endemic to the Qinghai-Tibetan Plateau. Genetic variation and population structure of 12 I. hypsophila populations were examined by using amplified fragment length polymorphism (AFLP) markers. Eight primer pairs produced a total of 472 unambiguous bands, of which 229 (48.5\%) were polymorphic. Intra-population genetic variation of Isoetes hypsophila was low (PP = 14.9\%, HE = 0.039, hs = 0.084 and I = 0.061). The F statistics calculated by different approaches consistently revealed high genetic differentiation among populations, contributing approximately 50\% of total gene diversity. Four genetic groups corresponding to four geographic regions were detected, indicating significant geographic structure. Our results suggest that both ongoing evolutionary forces (e.g., inbreeding system, bottlenecks resulting from fluctuation of water level) and historical events (e.g., orogenic movements which reduce gene flow among populations, repeated population retreat, and recolonization during ice ages) may have contributed to the genetic structure of I. hypsophila. In conservation, attention should be paid to preserving every population, and intra-region translocations can currently be recommended. {\textcopyright} 2010 Springer-Verlag.},

I. iapygia is similar to the amphibious species for the lack of phyllopodia, even if it has scales; it is similar to terrestrial species for the complete velum and tuberculate macrospores. A completely unique character is represented by the two air chambers. Its habitat is on limestone rocks, in temporary pools. {\textcopyright} 2010 Societ{\`a} Botanica Italiana.},

	abstract = {Background. Despite considerable progress in our understanding of land plant phylogeny, several nodes in the green tree of life remain poorly resolved. Furthermore, the bulk of currently available data come from only a subset of major land plant clades. Here we examine early land plant evolution using complete plastome sequences including two previously unexamined and phylogenetically critical lineages. To better understand the evolution of land plants and their plastomes, we examined aligned nucleotide sequences, indels, gene and nucleotide composition, inversions, and gene order at the boundaries of the inverted repeats. Results. We present the plastome sequences of Equisetum arvense, a horsetail, and of Isoetes flaccida, a heterosporous lycophyte. Phylogenetic analysis of aligned nucleotides from 49 plastome genes from 43 taxa supported monophyly for the following clades: embryophytes (land plants), lycophytes, monilophytes (leptosporangiate ferns + Angiopteris evecta + Psilotum nudum + Equisetum arvense), and seed plants. Resolution among the four monilophyte lineages remained moderate, although nucleotide analyses suggested that P. nudum and E. arvense form a clade sister to A. evecta + leptosporangiate ferns. Results from phylogenetic analyses of nucleotides were consistent with the distribution of plastome gene rearrangements and with analysis of sequence gaps resulting from insertions and deletions (indels). We found one new indel and an inversion of a block of genes that unites the monilophytes. Conclusions. Monophyly of monilophytes has been disputed on the basis of morphological and fossil evidence. In the context of a broad sampling of land plant data we find several new pieces of evidence for monilophyte monophyly. Results from this study demonstrate resolution among the four monilophytes lineages, albeit with moderate support; we posit a clade consisting of Equisetaceae and Psilotaceae that is sister to the "true ferns," including Marattiaceae. {\textcopyright} 2010 Karol et al; licensee BioMed Central Ltd.},

	abstract = {The goal of this research was to investigate genetic variation in Iso{\"e}tes malinverniana (Iso{\"e}taceae) to select candidate populations for future conservation efforts. To this aim, ISSR and AFLP analyses, carried out using six and four primer combinations, respectively, produced a total of 425 bands, 97.18\% of which were polymorphic.Our results suggest that I. malinverniana shows medium to high genetic diversity (mean Nei{\textquoteright}s genetic diversity: H=0.1491 for ISSR data; H=0.2289 for AFLP data) and a substantial amount of gene flow between the analysed populations (Nm=1.768, with combined ISSR and AFLP data). The moderate levels of population differentiation support the hypothesis that the fragmentation and isolation of I. malinverniana occurred only recently, probably due to the intensive agriculture practice and water pollution.These results will be used to focus further studies aimed at supporting reintroduction programs within suitable sites of the distribution area. {\textcopyright} 2010 Elsevier B.V.},

In section, the sporoderm is 100μm thick including the ornamentation. The wall is composed of a siliceous perispore, which consists of short fused flatten, elements forming a three-dimensional mesh. The exospore has two zones of different structure. The endospore is fibrillar. The microspores are monolete, 21-27μm in equatorial diameter. The sporoderm is composed of a sporopollinic rugulate perispore. A space between the para-exospore and the exospore is evident. The exospore is compact. The endospore is fibrillar. The ultrastructural analysis akes hoologies evident concerning structure and organization of the layers belo the perispore in both spore types. A possible similarity and stability in the ultrustructure of the present spores and fossils could be also inferred. In addition, there would be a correlation among the plant habitat, the spore ornamentation and the geographic distribution.},

	abstract = {The content of main nutritional components in soil of natural habitat of two plots (Shupowan and Xiaolanhu in Songyang of Zhejiang Province) of Iso{\"e}tes orientalis H. Liu et Q. F. Wang was comparatively analyzed, and the pH value of water in plot of Shupowan was determined. On this basis, the factors of soil and water led to I. orientalis endangered were discussed. The results show that contents of organic matter, total nitrogen, available phosphorus, available potassium and total iron ions (including Fe 3+ and Fe 2+) in soil of Shupowan are 102. 7 g {\textperiodcentered} kg -1, 3.1 g {\textperiodcentered} kg -1, 18.1 μg {\textperiodcentered} g -1, 15.0 μg {\textperiodcentered} g -1 and 221. 6 μg {\textperiodcentered} g -1, respectively, and those in soil of Xiaolanhu are 122. 8 g {\textperiodcentered} kg -1, 4. 8 g {\textperiodcentered} kg -1, 13. 7 μg {\textperiodcentered} g -1, 7. 1 μg {\textperiodcentered} g -1 and 240.0μg {\textperiodcentered} g -1, respectively. The contents of organic matter, total nitrogen and available potassium in soil of Xiaolanhu are significantly or very significantly higher than those of Shupowan, while the content differences of available phosphorus and total iron ions are not significant between two plots. But the available potassium content in soil of two plots is very low, while the total iron ion content is rich. The water pH values in upper, middle and down streams of Shupowan are pH 6. 35, pH 6.53 and pH 6.49, respectively, showing approximately neutral. It is suggested that the soil type in the two natural plots is the type which the contents of organic matter, total nitrogen, available phosphorus and total iron ions are rich, and the available potassium content is low. And extreme lack of available potassium in soil and water neutralization are probably the important environmental factors to limit development of I. orientalis population.},
