First Record of Two Euplotes Ciliates (Ciliophora: Spirotrichea: Euplotida) from Korea

“…However in this original description, the important information for species identification such as the exact cirral pattern (number of AZM, FVC, TC, DK, and dikinetids of mid-DK) and silverline system was not provided. Later, Tuffrau (1960) redescribed their population using the Chatton-Lwoff staining method Lwoff, 1930, 1935). The description of the present population is almost identical to that of Tuffrau's (1960) population in size of body (55-75 μm in long, size strongly overlapped); number of FVC (10), TC (5), DK (8); type of dargyrome (single-vannus) with exception of shape of body; number of AZM, CC, and cilia of mid-DK.…”

Tuffrau (1960) noted the form of body, clearly ovoid, while this population has an elongated oval form.…”

“…Over 100 species have been described in this genus from the world (Berger, 2001). After the pattern of the silverline system came to be considered as an important factor for species classification, many elements on the classification of the euplotid species have been newly revised by taxonomists (Tuffrau, 1960;Borror, 1968Borror, , 1972Carter, 1972;Curds, 1974;Gates, 1978).…”

Polygenic control of an all-or-none morphological trait in Euplotes (Ciliata, Hypotrichea). Evolutionary significance of naturally occurring morphological variation in Ciliates

“…If E balticus is excluded, since the information available on this taxon is very poor, the section A of the genus Euplotes, as defined by Curds (1975), is very likely to be monophyletic on the basis of many similarities in ciliary patterns and arrangement of the dorsal argyrome (Tuffrau, 1960;Curds, 1975;Gates, 1978aGates, , 1978b, mating type systems (Heckmann, 1963(Heckmann, , 1964Nobili, 1966;Wichterman, 1967), electrophoretic patterns (Schlegel et al, 1988), habitat, etc. Since the oldest specific epithet applying to a category included in this section is vannus (Miiller, 1786), this valid infrageneric taxon may be conveniently referred to as &dquo;the vannus group of genus Euplotes&dquo; (G6nermont et al, 1985). Within it, 3 entities can be separated on the basis of morphometric, biochemical and ecological criteria (Machelon et al, 1984;G6nermont et al, 1985;Valbonesi et al, 1988;Gianni and Piras, 1990).…”

“…纤毛虫原生动物为单细胞真核生物, 种类繁多, 其自由生活的类群广泛分布于海洋、淡水和土壤等 各种生境, 甚至在苔原、极地和高盐等极端生境中 也有发现, 还有一些类群营寄生或共栖生活 Qu et al, 2015;Dong et al, 2016;Li et al, 2016)。纤毛虫高度分化的细胞器、分司不同功能的 两型核结构以及特有的有性生殖方式(接合生殖), 使其作为重要的模式生物在细胞生物学、遗传学、 生态学以及真核生物的起源和进化等领域具有重 要的研究价值 (Corliss, 1979;Lynn, 2008;宋微波等, 2009)。 游仆类是纤毛虫中进化最为复杂和高等的一 大类群, 其多样性、发生学及系统学一直是国内外 研究的热点 (Carter, 1972;Curds, 1975;Shao et al, 2010;Yi et al, 2012)。经典的系统分类中, 游仆类隶 属于纤毛虫中的腹毛类 (Kahl, 1932;Borror, 1972;Corliss, 1979;Borror & Hill, 1995) (5-AAC CTG GTT GAT CCT GCC AGT-3)和18s-R (5-TGA TCC TTC TGC AGG TTC ACC TAC-3) (Medlin et al, 1988)。PCR扩增后, 产物直接送测序 公司测序 (Yi et al, 2009)。 额腹棘毛数目 Number of frontoventral cirri 9 9 9 9.0 0 0 19 (Pierson, 1943;Tuffrau, 1960;Pierson et al, 1968;Carter, 1972 虫为名的种群, 实际均为小腔游仆虫 (Pierson et al, 1968;Curds, 1975;庞延斌和魏红兵, 1999 Tuffrau, 1960;Carter, 1972;Curds, 1975 来源于独立发生的原基; 左缘棘毛原基独立发生等 (Washburn & Borror, 1972;Ruffolo, 1976;Shao et al, 2010;Fotedar et al, 2016 …”
