    A combination of field and herbarium surveys recorded a total of 34 plant species, one variety of aquatic vascular plant, two aquatic moss species and two charophyte species in Lake Ozenuma and the wetlands surrounding the lake. As a result of the surveys, Acorus calamus L., Typha latifolia L., Potamogeton octandrus Poir. and Schoenoplectus nipponicus (Makino) Soják were newly recorded in the area. However, the former two species are presumed to have occurred in the region in the early of the 2000s. Further, four of the species that were previously recorded as being distributed in the region were considered to have been misidentified; i.e. specimens previously identified as P. nipponicus Makino, S. tabernaemontani (C.C.Gmel.) Palla, Myriophyllum spicatum L. and Utricularia intermedia Heyne were identified as P. gramineus L., S. lacustris (L.) Palla, M. verticillatum L. and U. ochroleuca R.W.Hartm in this study, respectively.

    A small semiartificial pond, revealing high species richness with respect to the aquatic macrophytes, was studied in the Aomori Prefecture, Japan. The pond had been completely formed ca. 10 years previously after excavation into a wet bog. To identify and evaluate its aquatic macrophyte flora during 2017-2018, we listed the species of aquatic vascular plants and charophytes in the pond and compared this list with those from the natural Japanese lakes using a database of aquatic flora in Japan. Two species were identified by molecular analyses because they lacked any reproductive organs, which were necessary for identifying the species level. We found a total of 57 taxa of aquatic macrophytes including 15 Red List species in Japan or Aomori Prefecture. Comparing the flora list with those from the 66 natural Japanese lakes surveyed since 2001, the pond was ranked fourth in the order of diversity (based on species richness) and rarity (based on numbers of Red List species). Therefore, the pond is an important aquatic environment in terms of aquatic macrophyte conservation in Japan. Interestingly, for a pond with such high species diversity, it is relatively small (0.14 km(2)), semiartificial, and relatively recently formed.

    山梨県の水田域において2017年7〜8月に160定点を設定して水草・大型藻類の出現定点数、概略的な確認頻度(CR)、コドラートを用いた被度、全長、頻度を求め,これら5項目から積算優占度SDR5を算出し、それぞれの項目間の相関関係をスピアマンの順位相関により比較した。その結果、山梨県の水田域から水草34種(抽水植物16種、浮葉植物2種、浮遊植物5種、沈水植物11種)、大型藻14種(車軸藻類2種、その他大型藻12種)の計48種を確認することができた。SDR5値より、アオウキクサが最優占種、オモダカ、コナギ、クログワイ、アミミドロ属sp.、ウキクサが亜優占種と判断された。全種またはSDR5上位21種のSDR5値と出現定点数や平均CR値に高い相関が認められたことから、陸水域における広範囲の植生調査において優占度を簡便に評価するには今回行った概略的な確認頻度の4段階評価が優れていると考えられた。

    山梨県の水田域において2016年に120定点で行った定性調査の結果と2017年に161定点で行った定量調査の結果を基に,各市町村間で群集類似度をHornの重複度指数により算出し,クラスター解析を最短距離法により行った。類似度は甲斐市と北杜市で最も高く,次いで甲府市と南アルプス市,昭和町と南アルプス市であり,隣接するか距離的に近い市町村間で高い傾向が見られた。これは距離的に近い場所では環境が似ていることや,水草・大型藻類の移入頻度などに起因すると考えられた。クラスター解析では東部・富士五湖地方の4市町から成るクラスターと中西部の12市町全てを含んだクラスターが形成された。これら2つの地域は山によって隔てられていることから,標高や気温などが異なり,それらが水草・大型藻類の種組成や生育量に影響したものと推察された。

    Polymorphic simple sequence repeat (SSR) markers of Ecklonia radicosa were developed using Illumina MiSeq next-generation sequencing (NGS) analysis. In total, 3112 SSRs (di- to hexanucleotide motifs repeated more than six times) were identified from 61.5-Mb assembled genomic DNA using MISA perl script. Among the SSRs, di- (853 loci, 27.4%) and trinucleotides (1813 loci, 58.3%) were dominant, while tetra- (172 loci, 5.5%), penta- (175 loci, 5.6%), and hexanucleotides (99 loci, 3.2%) were not common. After specific amplification and polymorphic tests of 75 selected loci (tri- to hexanucleotide motifs repeated more than eight times), 11 SSR markers (Eradic01–11) were successfully developed. The range of the number of alleles, observed heterozygosity, and expected heterozygosity in the 11 markers was 3–13, 0.200–0.683, and 0.258–0.864, respectively. Polymorphic information content (PIC) analysis indicated that eight markers (Eradic01, 02, 04, 05, 06, 08, 09, and 11) were highly informative (PIC &gt
    0.5) and the other three were reasonably informative (0.5 &lt
    PIC &lt
    0.25). In addition, intra-genus amplification was obtained in all markers except for Eradic02, 08, and 11. These markers could help to reveal the genetic diversity and population structure of E. radicosa.

    The taxonomic status of Nitella flexilis var. bifurcata (Charales, Characeae), which is endemic to Japan, has remained unclear because there have been no records since its description in 1964, and the detailed morphology of fully mature individuals as well as its molecular phylogeny have not been studied. Recently, we collected a fully mature N.flexilis var. bifurcata from two lakes near the type locality in Japan. The morphological characteristics of the thalli agreed well with that in the original description of the taxon, with distinctive fertile and sterile branchlets that divided twice and unicellular dactyls. Scanning electron microscopy showed that the fine oospore structure of N.flexilis var. bifurcata was different from that of related taxa. In addition, molecular phylogenetic and haplotype network analyses using the chloroplast rbcL DNA sequences and the intergenic spacer regions between atpB and rbcL genes demonstrated that N.flexilis var. bifurcata and N.flexilis var. flexilis were distinct.

    Nitellopsis obtusa (Charales, Charophyceae) are widely distributed from Europe to Asia; however, this species has been recorded in only the five lakes in central Honshu in Japan. This species was thought to be extinct in Japan, but was rediscovered in limited areas of Lake Kawaguchi in central Honshu. More recently, we discovered more Japanese populations of N. obtusa in Lake Biwa in western Honshu, and it became clear that the species had a broader distribution in Japan than originally believed. In addition, although only male or female thalli have been collected at each lake, both male and female thalli were found from Lake Biwa. This is the first report of a potentially sexual population of N. obtusa in Japan. The DNA sequences of three chloroplast DNA markers, including both coding and non-coding regions, were identical in all specimens from Lake Kawaguchi and Lake Nojiri (Central Honshu), and differed from those of Lake Biwa and German specimens. Although Japanese and German specimens were genetically similar, Japanese specimens displayed considerable genetic diversity according to locality.

    Optimum conditions of temperature, salinity and glucose concentration were investigated for squalene production of the strain of Aurantiochytrium sp. 18W-13a, with a high content of squalene. Squalene production by this strain was optimum at 25 degrees C, 25-50% seawater concentration and 2-6% glucose concentration. When this strain was grown in the optimum condition, the squalene content and production of approximately 171 mg/g dry weight and 0.9 g/L. were much higher than that previously reported in thraustochytrids, plants and yeasts, respectively. Therefore, 18W-13a could be used as an alternative source of commercial squalene. (C) 2011 Elsevier Ltd. All rights reserved.

    A Botyrococcus braunii strain with high potential for biofuel production was isolated from a pond in Southeast Asia. This strain showed a higher growth rate (mu=0.101/day) and biomass productivity (2.61 dry cell weight (dcw) g/L), both of which are comparable to those of our benchmark strain B. braunii BOT-22. Chemical analyses indicated that this strain produced >44% of lipids (w/dcw), 21-37% of which was identified as C-34 botryococcene. 18S rDNA sequence analysis indicated this strain is closely related to BOT-22, suggesting that this strain can be affiliated into Race B. Interestingly, microscopic observations revealed that this strain harboured numerous bacterial ectosymbionts at the rim of host Botryococcus colonies. Our results suggest that algal-bacterial symbiotic consortia may have a potential to improve the productivity of biofuels, providing us with an alternative to pure culture of oil-producing algae.

    Chara altaica A. Braun (Charales, Charophyceae), a monoecious species of the section Desvauxia, was newly found in Japan and studied by light and scanning electron microscopy (SEM) as well as gene sequence analysis of the large subunit of Rubisco (rbcL). Our first SEM observations of C. altaica oospores revealed that small papillae were scattered on the fossa wall, an SEM oospore wall ornamentation that is essentially different from that of the monoecious species C. (sect. Desvauxia) evoluta T. F. Allen. Phylogenetic analysis demonstrated that C. altaica and 10 European samples of the dioecious species C. (sect. Desvauxia) canescens Desvaux & Loiseleur-Deslongchamps formed a robust monophyletic group, in which the rbcL gene sequence from C. altaica is identical to those from 4 parthenogenetic samples, but different from 6 other bisexual and parthenogenetic samples of C. canescens.

    Chara braunii is a charalean species that grows in a range of aquatic habitats from shallow water in paddy fields to the bottom of deep lakes. More than 30 infraspecific taxa have been proposed within this species because of its morphological variability. In order to reexamine the infraspecific taxa and habitat preference of C. braunii, we carried out molecular phylogenetic analyses and quantitative measurements of morphological characters used for infraspecific taxa, based on samples collected from various habitats and localities in Japan. Sequence data from the gene encoding the large subunit of Rubisco (rbcL) and the intergenic spacer regions between the beta subunit of the ATP synthase and rbcL genes demonstrated two robust clades (groups A and B). Samples of group A were collected mainly from shallow aquatic environments (< 15 cm in depth) such as paddy fields, while those of group B were mainly composed of samples found in deep aquatic environments (> 1 m in depth) such as lakes or ponds. Groups A and B therefore seem to represent closely related entities that have recently differentiated and might adapt to two different aquatic environments. However, the morphological measurements suggested these groups can be delineated by neither of the traditional diagnoses that were different between infraspecific taxa of Japanese plants of C. braunii.

    Mature zygotes of the cosmopolitan snow alga Chloromonas nivalis (Chodat) Hoham & Mullet [=Scotiella nivalis (Chodat) Fritsch] collected from Mt. Gassan, Yamagata Prefecture, were examined by scanning electron microscopy (SEM) and single-cell sequencing of the large subunit of Rubisco (rbcL) genes. I-lie present SEM demonstrated that Japanese samples have at least two types of flanges on the zygote wall (straight and sigmate). Although these types fell within the morphological variability of C nivalis as reported previously, at least two types of rbcL (large Subunit of Rubisco) gene sequences were detected by Using the single-cell sequencing. Although the information of the rh(L genes were limited (340-400 bp), the present phylogenetic analyses revealed that these two Japanese types and C. nivalis originating front North America belong to the lineage composed of Chloromonas snow taxa. Thus, C. nivalis might involve multiple cryptic species of Chloromonas. Further ovservations of other stages of life cycle and more detailed phylogenetic analysis are needed to reveal the correct taxonomic identifications of C. nivalis.

    シダ植物の博物館標本胞子の生存可能性を評価するために、昨年度標本胞子の発芽試験を行った種に加えて、新たにスギナ(トクサ科)、オオハナワラビ(ハナワラビ科)の2種を研究対象種に加えた。2021年度は、大阪市立自然史博物館と新潟大学の植物標本庫に収蔵されている標本よりそれぞれ胞子(以下、標本胞子と呼ぶ)を新たに得た。
    また、胞子の生理活性を評価するために、オオハナワラビ20標本、スギナ18標本、ゼンマイ19標本に標本胞子に対して、MTTを用いたテトラゾリウム染色試験を行った。オオハナワラビは、標本作成からの経過時間が183ヶ月(15年)の胞子の生存率が85.5±1.7%と最も高く、446ヶ月(38年)経過した胞子の生存率が37.9±4.2%と2番目に高かった。それ以外の年代の胞子は生存率が10%を下回っており、6標本においては0%であった。スギナやゼンマイでは、標本作成からの経過時間が30年から40年にかけて生存率は緩やかに減少した。しかし、各種の幾つかの古い標本では過剰に染色される胞子も確認され、胞子の生存を過剰評価している可能性が考えられた。
    車軸藻類については、昨年度に続き野外採集を行い発芽試験のための標本を増強するとともに、昨年度と今年度作製したシャジクモの標本(群馬県水田産1集団、新潟県ため池産2集団)より卵胞子を採取し、発芽試験(標本卵胞子およびコントロールデータのための非標本卵胞子を各50粒播種、6反復実施)を行った。その結果、新潟県産2集団の標本卵胞子において発芽が認められた(0.3±0.82%~2.7±0.01%)。これまでの研究で卵胞子に乾燥耐性があることは一部の種で示されていたが、標本の卵胞子に着目して発芽を確認したのは本研究が初めてである。今後、車軸藻類においても博物館標本の利用可能性を検討する価値があることを示すデータが得られた。

    The purpose of this research was to reconstruct the waterfront environment in late 19th century Japan by investigating biological specimens collected in 1879 by the Swedish Vega expedition led by Nordenskiold. The whole Japanese specimens collected by the Vega collection, as well as their records, are stored in the Swedish Museum of Natural History, Stockholm, and were identified by first-hand examination at the museum.
    The specimens were collected in mainly three regions: Kanto Region including Tokyo Bay, Kansai Region including Lake Biwa, and Nagasaki. The specimens contained some of the rare or extinct species in these regions today. As results, the Vega specimens turned out to have important scientific materials that helped us to reconstruct the ecological evidence of these localities in 1879, which had been severely damaged by the various anthropogenic influences during the 20th century.
