	abstract = {Mature ligules of Isoetes lacustris can be divided anatomically into three ultrastructurally different regions. First, the basal region contains large numbers of two types of protein bodies. Second, the cells of the sub-marginal region are characterized by a well developed Golgi apparatus closely associated with the tubular compartments of the endoplasmic reticulum. Third, the peripheral region consists of one to three layers of cells showing an extremely well developed rough asternal and smooth tubular endoplasmic reticulum (ER). The tubular ER compartments are frequently observed in close attachment to the plasmalemma. The outermost peripheral cells are covered with a mucilaginous layer. The dry matter in the mucilage consists of 49 per cent polysaccharides and 22 per cent proteins. The polysaccharide fraction, analysed by ion exchange chromato-graphy, consists mainly of glucose, arabinose, galactose and uronic acids. The protein fraction was analysed by SDS gel dectrophoresis and by high performance liquid-chromatographic separation of the amino acids. The analysis shows a protein pattern very similar to that of the peripheral ligule tissue. It is suggested, therefore, that the material of the external mucilage is secreted by the peripheral ligule cells. The secretional mechanism appears to be a direct release of polysaccharides and proteins by the tubular components of the ER. There is no indication of secretion via the Golgi apparatus. Because of its high activity in protein synthesis and secretion, it is suggested that the ligule is a vestigial structure, which, in extinct genera, might have functioned as a digestive organ. {\textcopyright} 1982 Annals of Botany Company.},

	abstract = {The basal cells in the ligule of Isoetes lacustris contain numerous protein bodies, the contents of which can be digested enzymically by pronase and are stained red by treatment with ninhydrin Schiff{\textquoteright}s reagent. Two types of protein bodies can be distinguished ultrastructurally: spherically-shaped bodies with granular contents and spindle-like bodies with fibrillar contents. Both are ensheathed by single membranes and do not show any solid inclusions within their matrix.The protein bodies probably arise from dilatation of the endoplasmic reticulum (ER) cisternae. This conclusion is based upon three observations: (a) The protein bodies occasionally show membrane continuity with the ER; (b) ribosomes and polysomes are frequently attached to the protein-body membranes; (c) the contents of the protein bodies and of the dilated ER cisternae show similar ultrastructural features.The dilatation of the ER cisternae is assumed to be a result of protein accumulation in the intracisternal space.Based upon the results of polyacrylamide gel electrophoresis, it is likely that the spherically-shaped protein bodies store predominately two proteins with molecular weights of 51300 and 55800 D, while the spindle-like bodies store two proteins with molecular weights of 92000 and 98000 D.The results presented do not permit a definite conclusion regarding the function of the ligule of Isoetes lacustris but it is suggested that it may have a nutritive role. {\textcopyright} 1981 Annals of Botany Company.},

	abstract = {Root tissues of Isoetes muricata Dur. were fixed in glutaraldehyde and postfixed in osmium tetroxide for electron microscopy. Very young root sieve elements can be distinguished from contiguous parenchyma cells by the presence of crystalline and/or fibrillar proteinaceous material in dilated cisternae of rough endoplasmic reticulum (ER). Similar crystalline-fibrillar material accumulates in the perinuclear space. During differentiation, the portions of ER enclosing this proteinaceous substance become smooth surfaced and migrate to the cell wall. Along the way many of them form multivesicular bodies which fuse with the plasmalemma, discharging their contents toward the wall. Nuclear degeneration is pycnotic. At maturity, the sieve element contains a degenerate, filiform nucleus, plastids, and mitochondria. In addition, the wall of the mature sieve element is lined by a plasmalemma and a parietal network of smooth ER. Sieve-area pores are present in both end and lateral walls of mature sieve elements. Whereas a single cluster of pores occurs in each end wall, the pores of the lateral walls are solitary and few in number. {\textcopyright} 1978 Annals of Botany Company.},

	abstract = {{\textbullet} Background and Aims: Isoetes sinensis (Isoeteaceae) is a critically endangered aquatic quillwort in eastern China. Rapid decline of extant population size and local population extinction have occurred in recent years and have raised great concerns among conservationists. {\textbullet} Methods: Amplified fragment length polymorphisms (AFLPs) were used to investigate the genetic variation and population structure of seven extant populations of the species. {\textbullet} Key Results: Eight primer combinations produced a total of 343 unambiguous bands of which 210 (61{\textperiodcentered}2 \%) were polymorphic. Isoetes sinensis exhibited a high level of intra-population genetic diversity (H E) = 0{\textperiodcentered}118; hs = 0{\textperiodcentered}147; I = 0{\textperiodcentered}192; P = 35{\textperiodcentered}2 \%). The genetic variation within each of the populations was not positively correlated with their size, suggesting recent population decline, which is well in accordance with field data of demographic surveys. Moreover, a high degree of genetic differentiation (FST = 0{\textperiodcentered}535; G ST = 0{\textperiodcentered}608; θB = 0{\textperiodcentered}607) was detected among populations and no correlation was found between geographical and genetic distance, suggesting that populations were in disequilibrium of migration-drift. Genetic drift played a more important role than gene flow in the current population genetic structure of I. sinensis because migration of I. sinensis is predominantly water-mediated and habitat range was highly influenced by environment changes. {\textbullet} Conclusions: Genetic information obtained in the present study provides useful baseline data for formulating conservation strategies. Conservation management, including both reinforcement for in situ populations and ex situ conservation programmes should be carefully designed to avoid the potential risk of outbreeding depression by admixture of individuals from different regions. However, translocation within the same regional population should be considered as a measure of genetic enhancement to rehabilitate local populations. An ex situ conservation strategy for conserving all extant populations to maximize genomic representation of the species is also recommended. {\textcopyright} The Author 2005.
